      Mining for the clean energy transition

      by

      In a world powered increasingly by clean energy, drilling for oil and gas will gradually give way to digging for metals and minerals. Today, the “critical minerals” used to make electric cars, solar panels, wind turbines, and grid-scale battery storage are facing soaring demand — and some acute bottlenecks as miners race to catch up.

      According to a report from the International Energy Agency, by 2040, the worldwide demand for copper is expected to roughly double; demand for nickel and cobalt will grow at least sixfold; and the world’s hunger for lithium could reach 40 times what we use today.

      “Society is looking to the clean energy transition as a way to solve the environmental and social harms of climate change,” says Scott Odell, a visiting scientist at the MIT Environmental Solutions Initiative (ESI), where he helps run the ESI Mining, Environment, and Society Program, who is also a visiting assistant professor at George Washington University. “Yet mining the materials needed for that transition would also cause social and environmental impacts. So we need to look for ways to reduce our demand for minerals, while also improving current mining practices to minimize social and environmental impacts.”

      ESI recently hosted the inaugural MIT Conference on Mining, Environment, and Society to discuss how the clean energy transition may affect mining and the people and environments in mining areas. The conference convened representatives of mining companies, environmental and human rights groups, policymakers, and social and natural scientists to identify key concerns and possible collaborative solutions.

      “We can’t replace an abusive fossil fuel industry with an abusive mining industry that expands as we move through the energy transition,” said Jim Wormington, a senior researcher at Human Rights Watch, in a panel on the first day of the conference. “There’s a recognition from governments, civil society, and companies that this transition potentially has a really significant human rights and social cost, both in terms of emissions […] but also for communities and workers who are on the front lines of mining.”

      That focus on communities and workers was consistent throughout the three-day conference, as participants outlined the economic and social dimensions of standing up large numbers of new mines. Corporate mines can bring large influxes of government revenue and local investment, but the income is volatile and can leave policymakers and communities stranded when production declines or mineral prices fall. On the other hand, “artisanal” mining operations are an important source of critical minerals, but are hard to regulate and subject to abuses from brokers. And large reserves of minerals are found in conservation areas, regions with fragile ecosystems and experiencing water shortages that can be exacerbated by mining, in particular on Indigenous-controlled lands and other places where mine openings are deeply fraught.

      “One of the real triggers of conflict is a dissatisfaction with the current model of resource extraction,” said Jocelyn Fraser of the University of British Columbia in a panel discussion. “One that’s failed to support the long-term sustainable development of regions that host mining operations, and yet imposes significant local social and environmental impacts.”

      All these challenges point toward solutions in policy and in mining companies’ relationships with the communities where they work. Participants highlighted newer models of mining governance that can create better incentives for the ways mines operate — from full community ownership of mines to recognizing community rights to the benefits of mining to end-of-life planning for mines at the time they open.

      Many of the conference speakers also shared technological innovations that may help reduce mining challenges. Some operations are investing in desalination as alternative water sources in water-scarce regions; low-carbon alternatives are emerging to many of the fossil fuel-powered heavy machines that are mainstays of the industry; and work is being done to reclaim valuable minerals from mine tailings, helping to minimize both waste and the need to open new extraction sites.

      Increasingly, the mining industry itself is recognizing that reforms will allow it to thrive in a rapid clean-energy transition. “Decarbonization is really a profitability imperative,” said Kareemah Mohammed, managing director for sustainability services at the technology consultancy Accenture, on the conference’s second day. “It’s about securing a low-cost and steady supply of either minerals or metals, but it’s also doing so in an optimal way.”

      The three-day conference attracted over 350 attendees, from large mining companies, industry groups, consultancies, multilateral institutions, universities, nongovernmental organizations (NGOs), government, and more. It was held entirely virtually, a choice that helped make the conference not only truly international — participants joined from over 27 countries on six continents — but also accessible to members of nonprofits and professionals in the developing world.

      “Many people are concerned about the environmental and social challenges of supplying the clean energy revolution, and we’d heard repeatedly that there wasn’t a forum for government, industry, academia, NGOs, and communities to all sit at the same table and explore collaborative solutions,” says Christopher Noble, ESI’s director of corporate engagement. “Convening, and researching best practices, are roles that universities can play. The conversations at this conference have generated valuable ideas and consensus to pursue three parallel programs: best-in-class models for community engagement, improving ESG metrics and their use, and civil-society contributions to government/industry relations. We are developing these programs to keep the momentum going.”

      The MIT Conference on Mining, Environment, and Society was funded, in part, by Accenture, as part of the MIT/Accenture Convergence Initiative. Additional funding was provided by the Inter-American Development Bank. More

      A breakthrough on “loss and damage,” but also disappointment, at UN climate conference

      by

      As the 2022 United Nations climate change conference, known as COP27, stretched into its final hours on Saturday, Nov. 19, it was uncertain what kind of agreement might emerge from two weeks of intensive international negotiations.

      In the end, COP27 produced mixed results: on the one hand, a historic agreement for wealthy countries to compensate low-income countries for “loss and damage,” but on the other, limited progress on new plans for reducing the greenhouse gas emissions that are warming the planet.

      “We need to drastically reduce emissions now — and this is an issue this COP did not address,” said U.N. Secretary-General António Guterres in a statement at the conclusion of COP27. “A fund for loss and damage is essential — but it’s not an answer if the climate crisis washes a small island state off the map — or turns an entire African country to desert.”

      Throughout the two weeks of the conference, a delegation of MIT students, faculty, and staff was at the Sharm El-Sheikh International Convention Center to observe the negotiations, conduct and share research, participate in panel discussions, and forge new connections with researchers, policymakers, and advocates from around the world.

      Loss and damage

      A key issue coming in to COP27 (COP stands for “conference of the parties” to the U.N. Framework Convention on Climate Change, held for the 27th time) was loss and damage: a term used by the U.N. to refer to harms caused by climate change — either through acute catastrophes like extreme weather events or slower-moving impacts like sea level rise — to which communities and countries are unable to adapt. 

      Ultimately, a deal on loss and damage proved to be COP27’s most prominent accomplishment. Negotiators reached an eleventh-hour agreement to “establish new funding arrangements for assisting developing countries that are particularly vulnerable to the adverse effects of climate change.” 

      “Providing financial assistance to developing countries so they can better respond to climate-related loss and damage is not only a moral issue, but also a pragmatic one,” said Michael Mehling, deputy director of the MIT Center for Energy and Environmental Policy Research, who attended COP27 and participated in side events. “Future emissions growth will be squarely centered in the developing world, and offering support through different channels is key to building the trust needed for more robust global cooperation on mitigation.”

      Youssef Shaker, a graduate student in the MIT Technology and Policy Program and a research assistant with the MIT Energy Initiative, attended the second week of the conference, where he followed the negotiations over loss and damage closely. 

      “While the creation of a fund is certainly an achievement,” Shaker said, “significant questions remain to be answered, such as the size of the funding available as well as which countries receive access to it.” A loss-and-damage fund that is not adequately funded, Shaker noted, “would not be an impactful outcome.” 

      The agreement on loss and damage created a new committee, made up of 24 country representatives, to “operationalize” the new funding arrangements, including identifying funding sources. The committee is tasked with delivering a set of recommendations at COP28, which will take place next year in Dubai.

      Advising the U.N. on net zero

      Though the decisions reached at COP27 did not include major new commitments on reducing emissions from the combustion of fossil fuels, the transition to a clean global energy system was nevertheless a key topic of conversation throughout the conference.

      The Council of Engineers for the Energy Transition (CEET), an independent, international body of engineers and energy systems experts formed to provide advice to the U.N. on achieving net-zero emissions globally by 2050, convened for the first time at COP27. Jessika Trancik, a professor in the MIT Institute for Data, Systems, and Society and a member of CEET, spoke on a U.N.-sponsored panel on solutions for the transition to clean energy.

      Trancik noted that the energy transition will look different in different regions of the world. “As engineers, we need to understand those local contexts and design solutions around those local contexts — that’s absolutely essential to support a rapid and equitable energy transition.”

      At the same time, Trancik noted that there is now a set of “low-cost, ready-to-scale tools” available to every region — tools that resulted from a globally competitive process of innovation, stimulated by public policies in different countries, that dramatically drove down the costs of technologies like solar energy and lithium-ion batteries. The key, Trancik said, is for regional transition strategies to “tap into global processes of innovation.”

      Reinventing climate adaptation

      Elfatih Eltahir, the H. M. King Bhumibol Professor of Hydrology and Climate, traveled to COP27 to present plans for the Jameel Observatory Climate Resilience Early Warning System (CREWSnet), one of the five projects selected in April 2022 as a flagship in MIT’s Climate Grand Challenges initiative. CREWSnet focuses on climate adaptation, the term for adapting to climate impacts that are unavoidable.

      The aim of CREWSnet, Eltahir told the audience during a panel discussion, is “nothing short of reinventing the process of climate change adaptation,” so that it is proactive rather than reactive; community-led; data-driven and evidence-based; and so that it integrates different climate risks, from heat waves to sea level rise, rather than treating them individually.

      “However, it’s easy to talk about these changes,” said Eltahir. “The real challenge, which we are now just launching and engaging in, is to demonstrate that on the ground.” Eltahir said that early demonstrations will happen in a couple of key locations, including southwest Bangladesh, where multiple climate risks — rising sea levels, increasing soil salinity, and intensifying heat waves and cyclones — are combining to threaten the area’s agricultural production.

      Building on COP26

      Some members of MIT’s delegation attended COP27 to advance efforts that had been formally announced at last year’s U.N. climate conference, COP26, in Glasgow, Scotland.

      At an official U.N. side event co-organized by MIT on Nov. 11, Greg Sixt, the director of the Food and Climate Systems Transformation (FACT) Alliance led by the Abdul Latif Jameel Water and Food Systems Lab, provided an update on the alliance’s work since its launch at COP26.

      Food systems are a major source of greenhouse gas emissions — and are increasingly vulnerable to climate impacts. The FACT Alliance works to better connect researchers to farmers, food businesses, policymakers, and other food systems stakeholders to make food systems (which include food production, consumption, and waste) more sustainable and resilient. 

      Sixt told the audience that the FACT Alliance now counts over 20 research and stakeholder institutions around the world among its members, but also collaborates with other institutions in an “open network model” to advance work in key areas — such as a new research project exploring how climate scenarios could affect global food supply chains.

      Marcela Angel, research program director for the Environmental Solutions Initiative (ESI), helped convene a meeting at COP27 of the Afro-InterAmerican Forum on Climate Change, which also launched at COP26. The forum works with Afro-descendant leaders across the Americas to address significant environmental issues, including climate risks and biodiversity loss. 

      At the event — convened with the Colombian government and the nonprofit Conservation International — ESI brought together leaders from six countries in the Americas and presented recent work that estimates that there are over 178 million individuals who identify as Afro-descendant living in the Americas, in lands of global environmental importance. 

      “There is a significant overlap between biodiversity hot spots, protected areas, and areas of high Afro-descendant presence,” said Angel. “But the role and climate contributions of these communities is understudied, and often made invisible.”    

      Limiting methane emissions

      Methane is a short-lived but potent greenhouse gas: When released into the atmosphere, it immediately traps about 120 times more heat than carbon dioxide does. More than 150 countries have now signed the Global Methane Pledge, launched at COP26, which aims to reduce methane emissions by at least 30 percent by 2030 compared to 2020 levels.

      Sergey Paltsev, the deputy director of the Joint Program on the Science and Policy of Global Change and a senior research scientist at the MIT Energy Initiative, gave the keynote address at a Nov. 17 event on methane, where he noted the importance of methane reductions from the oil and gas sector to meeting the 2030 goal.

      “The oil and gas sector is where methane emissions reductions could be achieved the fastest,” said Paltsev. “We also need to employ an integrated approach to address methane emissions in all sectors and all regions of the world because methane emissions reductions provide a near-term pathway to avoiding dangerous tipping points in the global climate system.”

      “Keep fighting relentlessly”

      Arina Khotimsky, a senior majoring in materials science and engineering and a co-president of the MIT Energy and Climate Club, attended the first week of COP27. She reflected on the experience in a social media post after returning home. 

      “COP will always have its haters. Is there greenwashing? Of course! Is everyone who should have a say in this process in the room? Not even close,” wrote Khotimsky. “So what does it take for COP to matter? It takes everyone who attended to not only put ‘climate’ on front-page news for two weeks, but to return home and keep fighting relentlessly against climate change. I know that I will.” More

      MIT Policy Hackathon produces new solutions for technology policy challenges

      by

      Almost three years ago, the Covid-19 pandemic changed the world. Many are still looking to uncover a “new normal.”

      “Instead of going back to normal, [there’s a new generation that] wants to build back something different, something better,” says Jorge Sandoval, a second-year graduate student in MIT’s Technology and Policy Program (TPP) at the Institute for Data, Systems and Society (IDSS). “How do we communicate this mindset to others, that the world cannot be the same as before?”

      This was the inspiration behind “A New (Re)generation,” this year’s theme for the IDSS-student-run MIT Policy Hackathon, which Sandoval helped to organize as the event chair. The Policy Hackathon is a weekend-long, interdisciplinary competition that brings together participants from around the globe to explore potential solutions to some of society’s greatest challenges. 

      Unlike other competitions of its kind, Sandoval says MIT’s event emphasizes a humanistic approach. “The idea of our hackathon is to promote applications of technology that are humanistic or human-centered,” he says. “We take the opportunity to examine aspects of technology in the spaces where they tend to interact with society and people, an opportunity most technical competitions don’t offer because their primary focus is on the technology.”

      The competition started with 50 teams spread across four challenge categories. This year’s categories included Internet and Cybersecurity, Environmental Justice, Logistics, and Housing and City Planning. While some people come into the challenge with friends, Sandoval said most teams form organically during an online networking meeting hosted by MIT.

      “We encourage people to pair up with others outside of their country and to form teams of different diverse backgrounds and ages,” Sandoval says. “We try to give people who are often not invited to the decision-making table the opportunity to be a policymaker, bringing in those with backgrounds in not only law, policy, or politics, but also medicine, and people who have careers in engineering or experience working in nonprofits.”

      Once an in-person event, the Policy Hackathon has gone through its own regeneration process these past three years, according to Sandoval. After going entirely online during the pandemic’s height, last year they successfully hosted the first hybrid version of the event, which served as their model again this year.

      “The hybrid version of the event gives us the opportunity to allow people to connect in a way that is lost if it is only online, while also keeping the wide range of accessibility, allowing people to join from anywhere in the world, regardless of nationality or income, to provide their input,” Sandoval says.

      For Swetha Tadisina, an undergraduate computer science major at Lafayette College and participant in the internet and cybersecurity category, the hackathon was a unique opportunity to meet and work with people much more advanced in their careers. “I was surprised how such a diverse team that had never met before was able to work so efficiently and creatively,” Tadisina says.

      Erika Spangler, a public high school teacher from Massachusetts and member of the environmental justice category’s winning team, says that while each member of “Team Slime Mold” came to the table with a different set of skills, they managed to be in sync from the start — even working across the nine-and-a-half-hour time difference the four-person team faced when working with policy advocate Shruti Nandy from Calcutta, India.

      “We divided the project into data, policy, and research and trusted each other’s expertise,” Spangler says, “Despite having separate areas of focus, we made sure to have regular check-ins to problem-solve and cross-pollinate ideas.”

      During the 48-hour period, her team proposed the creation of an algorithm to identify high-quality brownfields that could be cleaned up and used as sites for building renewable energy. Their corresponding policy sought to mandate additional requirements for renewable energy businesses seeking tax credits from the Inflation Reduction Act.

      “Their policy memo had the most in-depth technical assessment, including deep dives in a few key cities to show the impact of their proposed approach for site selection at a very granular level,” says Amanda Levin, director of policy analysis for the Natural Resources Defense Council (NRDC). Levin acted as both a judge and challenge provider for the environmental justice category.

      “They also presented their policy recommendations in the memo in a well-thought-out way, clearly noting the relevant actor,” she adds. This clarity around what can be done, and who would be responsible for those actions, is highly valuable for those in policy.”

      Levin says the NRDC, one of the largest environmental nonprofits in the United States, provided five “challenge questions,” making it clear that teams did not need to address all of them. She notes that this gave teams significant leeway, bringing a wide variety of recommendations to the table. 

      “As a challenge partner, the work put together by all the teams is already being used to help inform discussions about the implementation of the Inflation Reduction Act,” Levin says. “Being able to tap into the collective intelligence of the hackathon helped uncover new perspectives and policy solutions that can help make an impact in addressing the important policy challenges we face today.”

      While having partners with experience in data science and policy definitely helped, fellow Team Slime Mold member Sara Sheffels, a PhD candidate in MIT’s biomaterials program, says she was surprised how much her experiences outside of science and policy were relevant to the challenge: “My experience organizing MIT’s Graduate Student Union shaped my ideas about more meaningful community involvement in renewables projects on brownfields. It is not meaningful to merely educate people about the importance of renewables or ask them to sign off on a pre-planned project without addressing their other needs.”

      “I wanted to test my limits, gain exposure, and expand my world,” Tadisina adds. “The exposure, friendships, and experiences you gain in such a short period of time are incredible.”

      For Willy R. Vasquez, an electrical and computer engineering PhD student at the University of Texas, the hackathon is not to be missed. “If you’re interested in the intersection of tech, society, and policy, then this is a must-do experience.” More

      Machinery of the state

      by

      In Mai Hassan’s studies of Kenya, she documented the emergence of a sprawling administrative network officially billed as encouraging economic development, overseeing the population, and bolstering democracy. But Hassan’s field interviews and archival research revealed a more sinister purpose for the hundreds of administrative and security offices dotting the nation: “They were there to do the presidents’ bidding, which often involved coercing their own countrymen.”

      This research served as a catalyst for Hassan, who joined MIT as an associate professor of political science in July, to investigate what she calls the “politicized management of bureaucracy and the state.” She set out to “understand the motivations, capacities, and roles of people administering state programs and social functions,” she says. “I realized the state is not a faceless being, but instead comprised of bureaucrats carrying out functions on behalf of the state and the regime that runs it.”

      Today, Hassan’s portfolio encompasses not just the bureaucratic state but democratization efforts in Kenya and elsewhere in the East Africa region, including her native Sudan. Her research highlights the difficulties of democratization. “I’m finding that the conditions under which people come together for overthrowing an autocratic regime really matter, because those conditions may actually impede a nation from achieving democracy,” she says.

      A coordinated bureaucracy

      Hassan’s academic engagement with the state’s administrative machinery began during graduate school at Harvard University, where she earned her master’s and doctorate in government. While working with a community trash and sanitation program in some Kenyan Maasai communities, Hassan recalls “shepherding myself from office to office, meeting different bureaucrats to obtain the same approvals but for different jurisdictions.” The Kenyan state had recently set up hundreds of new local administrative units, motivated by what it claimed was the need for greater efficiency. But to Hassan’s eyes, “the administrative network was not well organized, seemed costly to maintain, and seemed to hinder — not bolster — development,” she says. What then, she wondered, was “the political logic behind such state restructuring?”

      Hassan began researching this bureaucratic transformation of Kenya, speaking with administrators in communities large and small who were charged with handling the business of the state. These studies yielded a wealth of findings for her dissertation, and for multiple journals.

      But upon finishing this tranche of research, Hassan realized that it was insufficient simply to study the structure of the state. “Understanding the role of new administrative structures for politics, development, and governance fundamentally requires that we understand who the government has put in charge of them,” she says. Among her insights:

      “The president’s office knows a lot of these administrators, and thinks about their strengths, limitations, and fit within a community,” says Hassan. Some administrators served the purposes of the central government by setting up water irrigation projects or building a new school. But in other villages, the state chose administrators who could act “much more coercively, ignoring development needs, throwing youth who supported the opposition into jail, and spending resources exclusively on policing.”

      Hassan’s work showed that in communities characterized by strong political opposition, “the local administration was always more coercive, regardless of an elected or autocratic president,” she says. Notably, the tenures of such officials proved shorter than those of their peers. “Once administrators get to know a community — going to church and the market with residents — it’s hard to coerce them,” explains Hassan.

      These short tenures come with costs, she notes: “Spending significant time in a station is useful for development, because you know exactly whom to hire if you want to build a school or get something done efficiently.” Politicizing these assignments undermines efforts at delivery of services and, more broadly, economic improvement nationwide. “Regimes that are more invested in retaining power must devote resources to establishing and maintaining control, resources that could otherwise be used for development and the welfare of citizens,” she says.

      Hassan wove together her research covering three presidents over a 50-year period, in the book, “Regime Threats and State Solutions: Bureaucratic Loyalty and Embeddedness in Kenya” (2020, Cambridge University Press), named a Foreign Affairs Best Book of 2020.

      Sudanese roots

      The role of the state in fulfilling the needs of its citizens has long fascinated Hassan. Her grandfather, who had served as Sudan’s ambassador to the USSR, talked to her about the advantages of a centralized government “that allocated resources to reduce inequality,” she says.

      Politics often dominated the conversation in gatherings of Hassan’s family and friends. Her parents immigrated to northern Virginia when she was very young, and many relatives joined them, part of a steady flow of Sudanese fleeing political turmoil and oppression.

      “A lot of people had expected more from the Sudanese state after independence and didn’t get it,” she says. “People had hopes for what the government could and should do.”

      Hassan’s Sudanese roots and ongoing connection to the Sudanese community have shaped her academic interests and goals. At the University of Virginia, she gravitated toward history and economics classes. But it was her time at the Ralph Bunche Summer institute that perhaps proved most pivotal in her journey. This five-week intensive program is offered by the American Political Science Association to introduce underrepresented undergraduate students to doctoral studies. “It was really compelling in this program to think rigorously about all the political ideas I’d heard as I was growing up, and find ways to challenge some assertions empirically,” she says.

      Regime change and civil society

      At Harvard, Hassan first set out to focus on Sudan for her doctoral program. “There wasn’t much scholarship on the country, and what there was lacked rigor,” she says. “That was something that needed to change.” But she decided to postpone this goal after realizing that she might be vulnerable as a student conducting field research there. She landed instead in Kenya, where she honed her interviewing and data collection skills.

      Today, empowered by her prior work, she has returned to Sudan. “I felt that the popular uprising in Sudan and ousting of the Islamist regime in 2019 should be documented and analyzed,” she says. “It was incredible that hundreds of thousands, if not millions, acted collectively to uproot a dictator, in the face of brutal violence from the state.”But “democracy is still uncertain there,” says Hassan. The broad coalition behind regime change “doesn’t know how to govern because different people and different sectors of society have different ideas about what democratic Sudan should look like,” she says. “Overthrowing an autocratic regime and having civil society come together to figure out what’s going to replace it require different things, and it’s unclear if a movement that accomplishes the first is well-suited to do the second.”

      Hassan believes that in order to create lasting democratization, “you need the hard work of building organizations, developing ways in which members learn to compromise among themselves, and make decisions and rules for how to move forward.”

      Hassan is enjoying the fall semester and teaching courses on autocracy and authoritarian regimes. She is excited as well about developing her work on African efforts at democratic mobilization in a political science department she describes as “policy-forward.”

      Over time, she hopes to connect with Institute scholars in the hard sciences to think about other challenges these nations are facing, such as climate change. “It’s really hot in Sudan, and it may be one of the first countries to become completely uninhabitable,” she says. “I’d like to explore strategies for growing crops differently or managing the exceedingly scarce resource of water, and figure out what kind of political discussions will be necessary to implement any changes. It is really critical to think about these problems in an interdisciplinary way.” More

      3 Questions: Robert Stoner unpacks US climate and infrastructure laws

      by

      This month, the 2022 United Nations Climate Change Conference (COP27) takes place in Sharm El Sheikh, Egypt, bringing together governments, experts, journalists, industry, and civil society to discuss climate action to enable countries to collectively sharply limit anthropogenic climate change. As MIT Energy Initiative Deputy Director for Science and Technology Robert Stoner attends the conference, he takes a moment to speak about the climate and infrastructure laws enacted in the last year in the United States, and about the impact these laws can have in the global energy transition.

      Q: COP27 is now underway. Can you set the scene?

      A: There’s a lot of interest among vulnerable countries about compensation for the impacts climate change has had on them, or “loss and damage,” a topic that the United States refused to address last year at COP26, for fear of opening up a floodgate and leaving U.S. taxpayers exposed to unlimited liability for our past (and future) emissions. This is a crucial issue of fairness for developed countries — and, well, of acknowledging our common humanity. But in a sense, it’s also a sideshow, and addressing it won’t prevent a climate catastrophe — we really need to focus on mitigation. With the passage of the bipartisan Infrastructure Investment and Jobs Act and the Inflation Reduction Act (IRA), the United States is now in a strong position to twist some arms. These laws are largely about subsidizing the deployment of low-carbon technologies — pretty much all of them. We’re going to do a lot in the United States in the next decade that will lead to dramatic cost reductions for these technologies and enable other countries with fewer resources to adopt them as well. It’s exactly the leadership role the United States has needed to assume. Now we have the opportunity to rally the rest of the world and get other countries to commit to more ambitious decarbonization goals, and to build practical programs that take advantage of the investable pathways we’re going to create for public and private actors.

      But that alone won’t get us there — money is still a huge problem, especially in emerging markets and developing countries. And I don’t think the institutions we rely on to help these countries fund infrastructure — energy and everything else — are adequately funded. Nor do these institutions have the right structures, incentives, and staffing to fund low-carbon development in these countries rapidly enough or on the necessary scale. I’m talking about the World Bank, for instance, but the other multilateral organizations have similar issues. I frankly don’t think the multilaterals can be reformed or sufficiently redirected on a short enough time frame. We definitely need new leadership for these organizations, and I think we probably need to quickly establish new multilaterals with new people, more money, and a clarity of purpose that is likely beyond what can be achieved incrementally. I don’t know if this is going to be an active public discussion at COP27, but I hope it takes place somewhere soon. Given the strong role our government plays in financing and selecting the leadership of these institutions, perhaps this is another opportunity for the United States to demonstrate courage and leadership.

      Q: What “investable pathways” are you talking about?

      A: Well, the pathways we’re implicitly trying to pursue with the Infrastructure Act and IRA are pretty clear, and I’ll come back to them. But first let me describe the landscape: There are three main sources of demand for energy in the economy — industry (meaning chemical production, fuel for electricity generation, cement production, materials and manufacturing, and so on), transportation (cars, trucks, ships, planes, and trains), and buildings (for heating and cooling, mostly). That’s about it, and these three sectors account for 75 percent of our total greenhouse gas emissions. So the pathways are all about how to decarbonize these three end-use sectors. There are a lot of technologies — some that exist, some that don’t — that will have to be brought to bear. And so it can be a little overwhelming to try to imagine how it will all transpire, but it’s pretty clear at a high level what our options are:

      First, generate a lot of low-carbon electricity and electrify as many industrial processes, vehicles, and building heating systems as we can.
      Second, develop and deploy at massive scale technologies that can capture carbon dioxide from smokestacks, or the air, and put it somewhere that it can never escape from — in other words, carbon capture and sequestration, or CCS.
      Third, for end uses like aviation that really need to use fuels because of their extraordinary energy density, develop low-carbon alternatives to fossil fuels.
      And fourth is energy efficiency across the board — but I don’t really count that as a separate pathway per se.
      So, by “investable pathways” I mean specific ways to pursue these options that will attract investors. What the Infrastructure Act and the IRA do is deploy carrots (in the form of subsidies) in a variety of ways to close the gap between what it costs to deploy technologies like CCS that aren’t yet at a commercial stage because they’re immature, and what energy markets will tolerate. A similar situation occurs for low-carbon production of hydrogen, one of the leading low-carbon fuel candidates. We can make it by splitting water with electricity (electrolysis), but that costs too much with present-day technology; or we can make it more cheaply by separating it from methane (which is what natural gas mainly is), but that creates CO2 that has to be transported and sequestered somewhere. And then we have to store the hydrogen until we’re ready to use it, and transport it by pipeline to the industrial facilities where it will be used. That requires infrastructure that doesn’t exist — pipelines, compression stations, big tanks! Come to think of it, the demand for all that hydrogen doesn’t exist either — at least not if industry has to pay what it actually costs.

      So, one very important thing these new acts do is subsidize production of hydrogen in various ways — and subsidize the creation of a CCS industry. The other thing they do is subsidize the deployment at enormous scale of low-carbon energy technologies. Some of them are already pretty cheap, like solar and wind, but they need to be supported by a lot of storage on the grid (which we don’t yet have) and by other sorts of grid infrastructure that, again, don’t exist. So, they now get subsidized, too, along with other carbon-free and low-carbon generation technologies — basically all of them. The idea is that by stimulating at-scale deployment of all these established and emerging technologies, and funding demonstrations of novel infrastructure — effectively lowering the cost of supply of low-carbon energy in the form of electricity and fuels — we will draw out the private sector to build out much more of the connective infrastructure and invest in new industrial processes, new home heating systems, and low-carbon transportation. This subsidized build-out will take place over a decade and then phase out as costs fall — hopefully, leaving the foundation for a thriving low-carbon energy economy in its wake, along with crucial technologies and knowledge that will benefit the whole world.

      Q: Is all of the federal investment in energy infrastructure in the United States relevant to the energy crisis in Europe right now?

      A: Not in a direct way — Europe is a near-term catastrophe with a long-term challenge that is in many ways more difficult than ours because Europe doesn’t have the level of primary energy resources like oil and gas that we have in abundance. Energy costs more in Europe, especially absent Russian pipelines. In a way, the narrowing of Europe’s options creates an impetus to invest in low-carbon technologies sooner than otherwise. The result either way will be expensive energy and quite a lot of economic suffering for years. The near-term challenge is to protect people from high energy prices. The big spikes in electricity prices we see now are driven by the natural gas market disruption, which will eventually dissipate as new sources of electricity come online (Sweden, for example, just announced a plan to develop new nuclear, and we’re seeing other countries like Germany soften their stance on nuclear) — and gas markets will sort themselves out. Meanwhile governments are trying to shield their people with electricity price caps and other subsidies, but that’s enormously burdensome.

      The EU recently announced gas price caps for imported gas to try to eliminate price-gouging by importers and reduce the subsidy burden. That may help to lower downstream prices, or it may make matters worse by reducing the flow of gas into the EU and fueling scarcity pricing, and ultimately adding to the subsidy burden. A lot people are quite reasonably suggesting that if electricity prices are subject to crazy behavior in gas markets, then why not disconnect from the grid and self-generate? Wouldn’t that also help reduce demand for gas overall and also reduce CO2 emissions? It would. But it’s expensive to put solar panels on your roof and batteries in your basement — so for those rich enough to do this, it would lead to higher average electricity costs that would live on far into the future, even when grid prices eventually come down.

      So, an interesting idea is taking hold, with considerable encouragement from national governments — the idea of “energy communities,” basically, towns or cities that encourage local firms and homeowners to install solar and batteries, and make some sort of business arrangement with the local utility to allow the community to disconnect from the national grid at times of high prices and self-supply — in other words, use the utility’s wires to sell locally generated power locally. It’s interesting to think about — it takes less battery storage to handle the intermittency of solar when you have a lot of generators and consumers, so forming a community helps lower costs, and with a good deal from the utility for using their wires, it might not be that much more expensive. And of course, when the national grid is working well and prices are normal, the community would reconnect and buy power cheaply, while selling back its self-generated power to the grid. There are also potentially important social benefits that might accrue in these energy communities, too. It’s not a dumb idea, and we’ll see some interesting experimentation in this area in the coming years — as usual, the Germans are enthusiastic! More

      Advancing the energy transition amidst global crises

      by

      “The past six years have been the warmest on the planet, and our track record on climate change mitigation is drastically short of what it needs to be,” said Robert C. Armstrong, MIT Energy Initiative (MITEI) director and the Chevron Professor of Chemical Engineering, introducing MITEI’s 15th Annual Research Conference.

      At the symposium, participants from academia, industry, and finance acknowledged the deepening difficulties of decarbonizing a world rocked by geopolitical conflicts and suffering from supply chain disruptions, energy insecurity, inflation, and a persistent pandemic. In spite of this grim backdrop, the conference offered evidence of significant progress in the energy transition. Researchers provided glimpses of a low-carbon future, presenting advances in such areas as long-duration energy storage, carbon capture, and renewable technologies.

      In his keynote remarks, Ernest J. Moniz, the Cecil and Ida Green Professor of Physics and Engineering Systems Emeritus, founding director of MITEI, and former U.S. secretary of energy, highlighted “four areas that have materially changed in the last year” that could shake up, and possibly accelerate, efforts to address climate change.

      Extreme weather seems to be propelling the public and policy makers of both U.S. parties toward “convergence … at least in recognition of the challenge,” Moniz said. He perceives a growing consensus that climate goals will require — in diminishing order of certainty — firm (always-on) power to complement renewable energy sources, a fuel (such as hydrogen) flowing alongside electricity, and removal of atmospheric carbon dioxide (CO2).

      Russia’s invasion of Ukraine, with its “weaponization of natural gas” and global energy impacts, underscores the idea that climate, energy security, and geopolitics “are now more or less recognized widely as one conversation.” Moniz pointed as well to new U.S. laws on climate change and infrastructure that will amplify the role of science and technology and “address the drive to technological dominance by China.”

      The rapid transformation of energy systems will require a comprehensive industrial policy, Moniz said. Government and industry must select and rapidly develop low-carbon fuels, firm power sources (possibly including nuclear power), CO2 removal systems, and long-duration energy storage technologies. “We will need to make progress on all fronts literally in this decade to come close to our goals for climate change mitigation,” he concluded.

      Global cooperation?

      Over two days, conference participants delved into many of the issues Moniz raised. In one of the first panels, scholars pondered whether the international community could forge a coordinated climate change response. The United States’ rift with China, especially over technology trade policies, loomed large.

      “Hatred of China is a bipartisan hobby and passion, but a blanket approach isn’t right, even for the sake of national security,” said Yasheng Huang, the Epoch Foundation Professor of Global Economics and Management at the MIT Sloan School of Management. “Although the United States and China working together would have huge effects for both countries, it is politically unpalatable in the short term,” said F. Taylor Fravel, the Arthur and Ruth Sloan Professor of Political Science and director of the MIT Security Studies Program. John E. Parsons, deputy director for research at the MIT Center for Energy and Environmental Policy Research, suggested that the United States should use this moment “to get our own act together … and start doing things,” such as building nuclear power plants in a cost-effective way.

      Debating carbon removal

      Several panels took up the matter of carbon emissions and the most promising technologies for contending with them. Charles Harvey, MIT professor of civil and environmental engineering, and Howard Herzog, a senior research engineer at MITEI, set the stage early, debating whether capturing carbon was essential to reaching net-zero targets.

      “I have no trouble getting to net zero without carbon capture and storage,” said David Keith, the Gordon McKay Professor of Applied Physics at Harvard University, in a subsequent roundtable. Carbon capture seems more risky to Keith than solar geoengineering, which involves injecting sulfur into the stratosphere to offset CO2 and its heat-trapping impacts.

      There are new ways of moving carbon from where it’s a problem to where it’s safer. Kripa K. Varanasi, MIT professor of mechanical engineering, described a process for modulating the pH of ocean water to remove CO2. Timothy Krysiek, managing director for Equinor Ventures, talked about construction of a 900-kilometer pipeline transporting CO2 from northern Germany to a large-scale storage site located in Norwegian waters 3,000 meters below the seabed. “We can use these offshore Norwegian assets as a giant carbon sink for Europe,” he said.

      A startup showcase featured additional approaches to the carbon challenge. Mantel, which received MITEI Seed Fund money, is developing molten salt material to capture carbon for long-term storage or for use in generating electricity. Verdox has come up with an electrochemical process for capturing dilute CO2 from the atmosphere.

      But while much of the global warming discussion focuses on CO2, other greenhouse gases are menacing. Another panel discussed measuring and mitigating these pollutants. “Methane has 82 times more warming power than CO2 from the point of emission,” said Desirée L. Plata, MIT associate professor of civil and environmental engineering. “Cutting methane is the strongest lever we have to slow climate change in the next 25 years — really the only lever.”

      Steven Hamburg, chief scientist and senior vice president of the Environmental Defense Fund, cautioned that emission of hydrogen molecules into the atmosphere can cause increases in other greenhouse gases such as methane, ozone, and water vapor. As researchers and industry turn to hydrogen as a fuel or as a feedstock for commercial processes, “we will need to minimize leakage … or risk increasing warming,” he said.

      Supply chains, markets, and new energy ventures

      In panels on energy storage and the clean energy supply chain, there were interesting discussions of challenges ahead. High-density energy materials such as lithium, cobalt, nickel, copper, and vanadium for grid-scale energy storage, electric vehicles (EVs), and other clean energy technologies, can be difficult to source. “These often come from water-stressed regions, and we need to be super thoughtful about environmental stresses,” said Elsa Olivetti, the Esther and Harold E. Edgerton Associate Professor in Materials Science and Engineering. She also noted that in light of the explosive growth in demand for metals such as lithium, recycling EVs won’t be of much help. “The amount of material coming back from end-of-life batteries is minor,” she said, until EVs are much further along in their adoption cycle.

      Arvind Sanger, founder and managing partner of Geosphere Capital, said that the United States should be developing its own rare earths and minerals, although gaining the know-how will take time, and overcoming “NIMBYism” (not in my backyard-ism) is a challenge. Sanger emphasized that we must continue to use “denser sources of energy” to catalyze the energy transition over the next decade. In particular, Sanger noted that “for every transition technology, steel is needed,” and steel is made in furnaces that use coal and natural gas. “It’s completely woolly-headed to think we can just go to a zero-fossil fuel future in a hurry,” he said.

      The topic of power markets occupied another panel, which focused on ways to ensure the distribution of reliable and affordable zero-carbon energy. Integrating intermittent resources such as wind and solar into the grid requires a suite of retail markets and new digital tools, said Anuradha Annaswamy, director of MIT’s Active-Adaptive Control Laboratory. Tim Schittekatte, a postdoc at the MIT Sloan School of Management, proposed auctions as a way of insuring consumers against periods of high market costs.

      Another panel described the very different investment needs of new energy startups, such as longer research and development phases. Hooisweng Ow, technology principal at Eni Next LLC Ventures, which is developing drilling technology for geothermal energy, recommends joint development and partnerships to reduce risk. Michael Kearney SM ’11, PhD ’19, SM ’19 is a partner at The Engine, a venture firm built by MIT investing in path-breaking technology to solve the toughest challenges in climate and other problems. Kearney believes the emergence of new technologies and markets will bring on “a labor transition on an order of magnitude never seen before in this country,” he said. “Workforce development is not a natural zone for startups … and this will have to change.”

      Supporting the global South

      The opportunities and challenges of the energy transition look quite different in the developing world. In conversation with Robert Armstrong, Luhut Binsar Pandjaitan, the coordinating minister for maritime affairs and investment of the Republic of Indonesia, reported that his “nation is rich with solar, wind, and energy transition minerals like nickel and copper,” but cannot on its own tackle developing renewable energy or reducing carbon emissions and improving grid infrastructure. “Education is a top priority, and we are very far behind in high technologies,” he said. “We need help and support from MIT to achieve our target,” he said.

      Technologies that could springboard Indonesia and other nations of the global South toward their climate goals are emerging in MITEI-supported projects and at young companies MITEI helped spawn. Among the promising innovations unveiled at the conference are new materials and designs for cooling buildings in hot climates and reducing the environmental costs of construction, and a sponge-like substance that passively sucks moisture out of the air to lower the energy required for running air conditioners in humid climates.

      Other ideas on the move from lab to market have great potential for industrialized nations as well, such as a computational framework for maximizing the energy output of ocean-based wind farms; a process for using ammonia as a renewable fuel with no CO2 emissions; long-duration energy storage derived from the oxidation of iron; and a laser-based method for unlocking geothermal steam to drive power plants.

      Coordinating climate and air-quality policies to improve public health

      by

      As America’s largest investment to fight climate change, the Inflation Reduction Act positions the country to reduce its greenhouse gas emissions by an estimated 40 percent below 2005 levels by 2030. But as it edges the United States closer to achieving its international climate commitment, the legislation is also expected to yield significant — and more immediate — improvements in the nation’s health. If successful in accelerating the transition from fossil fuels to clean energy alternatives, the IRA will sharply reduce atmospheric concentrations of fine particulates known to exacerbate respiratory and cardiovascular disease and cause premature deaths, along with other air pollutants that degrade human health. One recent study shows that eliminating air pollution from fossil fuels in the contiguous United States would prevent more than 50,000 premature deaths and avoid more than $600 billion in health costs each year.

      While national climate policies such as those advanced by the IRA can simultaneously help mitigate climate change and improve air quality, their results may vary widely when it comes to improving public health. That’s because the potential health benefits associated with air quality improvements are much greater in some regions and economic sectors than in others. Those benefits can be maximized, however, through a prudent combination of climate and air-quality policies.

      Several past studies have evaluated the likely health impacts of various policy combinations, but their usefulness has been limited due to a reliance on a small set of standard policy scenarios. More versatile tools are needed to model a wide range of climate and air-quality policy combinations and assess their collective effects on air quality and human health. Now researchers at the MIT Joint Program on the Science and Policy of Global Change and MIT Institute for Data, Systems and Society (IDSS) have developed a publicly available, flexible scenario tool that does just that.

      In a study published in the journal Geoscientific Model Development, the MIT team introduces its Tool for Air Pollution Scenarios (TAPS), which can be used to estimate the likely air-quality and health outcomes of a wide range of climate and air-quality policies at the regional, sectoral, and fuel-based level. 

      “This tool can help integrate the siloed sustainability issues of air pollution and climate action,” says the study’s lead author William Atkinson, who recently served as a Biogen Graduate Fellow and research assistant at the IDSS Technology and Policy Program’s (TPP) Research to Policy Engagement Initiative. “Climate action does not guarantee a clean air future, and vice versa — but the issues have similar sources that imply shared solutions if done right.”

      The study’s initial application of TAPS shows that with current air-quality policies and near-term Paris Agreement climate pledges alone, short-term pollution reductions give way to long-term increases — given the expected growth of emissions-intensive industrial and agricultural processes in developing regions. More ambitious climate and air-quality policies could be complementary, each reducing different pollutants substantially to give tremendous near- and long-term health benefits worldwide.

      “The significance of this work is that we can more confidently identify the long-term emission reduction strategies that also support air quality improvements,” says MIT Joint Program Deputy Director C. Adam Schlosser, a co-author of the study. “This is a win-win for setting climate targets that are also healthy targets.”

      TAPS projects air quality and health outcomes based on three integrated components: a recent global inventory of detailed emissions resulting from human activities (e.g., fossil fuel combustion, land-use change, industrial processes); multiple scenarios of emissions-generating human activities between now and the year 2100, produced by the MIT Economic Projection and Policy Analysis model; and emissions intensity (emissions per unit of activity) scenarios based on recent data from the Greenhouse Gas and Air Pollution Interactions and Synergies model.

      “We see the climate crisis as a health crisis, and believe that evidence-based approaches are key to making the most of this historic investment in the future, particularly for vulnerable communities,” says Johanna Jobin, global head of corporate reputation and responsibility at Biogen. “The scientific community has spoken with unanimity and alarm that not all climate-related actions deliver equal health benefits. We’re proud of our collaboration with the MIT Joint Program to develop this tool that can be used to bridge research-to-policy gaps, support policy decisions to promote health among vulnerable communities, and train the next generation of scientists and leaders for far-reaching impact.”

      The tool can inform decision-makers about a wide range of climate and air-quality policies. Policy scenarios can be applied to specific regions, sectors, or fuels to investigate policy combinations at a more granular level, or to target short-term actions with high-impact benefits.

      TAPS could be further developed to account for additional emissions sources and trends.

      “Our new tool could be used to examine a large range of both climate and air quality scenarios. As the framework is expanded, we can add detail for specific regions, as well as additional pollutants such as air toxics,” says study supervising co-author Noelle Selin, professor at IDSS and the MIT Department of Earth, Atmospheric and Planetary Sciences, and director of TPP.    

      This research was supported by the U.S. Environmental Protection Agency and its Science to Achieve Results (STAR) program; Biogen; TPP’s Leading Technology and Policy Initiative; and TPP’s Research to Policy Engagement Initiative. More

      Passion projects prepare to launch

      by

      At the start of the sixth annual MITdesignX “Pitch Day,” Svafa Grönfeldt, the program’s faculty director, made a point of noting that many of the teams about to showcase their ventures had changed direction multiple times on their projects.

      “Some of you have pivoted more times than we can count,” Grönfeldt said in her welcoming address. “This makes for a fantastic idea because you have the courage to actually question if your ideas are the right ones. In the true spirit of human-centered design, you actually try to understand the problem before you solve it!”

      MITdesignX, a venture accelerator based in the School of Architecture and Planning, is an interdisciplinary academic program operating at the intersection of design, business, and technology. The launching pad for startups focuses on applying design to engage complex problems and discovering high-impact solutions to address critical challenges facing the future of design, cities, and the global environment. The program reflects a new approach to entrepreneurship education, drawing on business theory, design thinking, and entrepreneurial practices.

      At this year’s event, 11 teams pitched their ideas before a panel of three judges, an on-site audience, and several hundred viewers watching the livestream event.

      “These teams have been working hard on solutions,” Gilad Rosenzweig, executive director of MITdesignX, told the audience. “They’re not designing solutions for people. They’re designing solutions with people.”

      Solving urgent problems

      Some of the issues addressed by the teams were lack of adequate housing, endangered food supplies, toxic pollution, and threats to democracy. Many of the students were inspired to create their venture because of problems they encountered in their careers or concerns impacting their home countries. The 25 team members in this year’s cohort represent work on five continents.

      “We’re very proud of our international representation because we want our impact to be felt outside of Cambridge,” said Rosenzweig. “We want to make an impact around the country and around the world.”

      John Devine, a JD/Masters in City Planning (MCP) candidate in the Department of Urban Studies and Planning, created a new software platform, “Civic Atlas.” In his pitch, he explained that having worked in city planning in Texas for a decade before coming to MIT, he saw how difficult it was for communities to wade through and comprehend the dense, technical language in city council agendas. Zoning cases, bond projects, and transportation investments are just some of the significant projects that affect a community, and Devine saw many instances where decisions were being made without community awareness as a result of inadequate communication.

      “When communities don’t have access to clear, accessible information, we have poor outcomes,” Devine told the audience. “I realized the solution to this is to make accessible and inclusive digital experiences that really facilitate communication between planners, developers, and members of the community.”

      Seizing the opportunity, Devine taught himself how to code and built a fully automated web tool for the Dallas City Planning Commission. The tool checks the city’s website daily and translates documents into interactive maps, allowing residents to view plans in their community. Devine is starting in Dallas, but says that there are more than 800 cities across the United States with a population greater than 50,000 that present an excellent target market for this product.

      “I think cities have a ton to gain from working with us, including building trust and communication with constituents — something that’s vital for city halls to function,” says Devine.

      Next steps for the cohort

      The judges for this year’s event — Yscaira Jimenez, founder of LaborX; Magnus Ingi Oskarsson of Eyrir Venture Management in Reykjavik, Iceland; and Frank Pawlitschek, director, HPI School of Entrepreneurship in Potsdam, Germany — deliberated to identify the best teams based on three criteria: most innovative, greatest impact, and best presentation. The competition was so strong that the judges decided to award two honorable mentions. This year’s awardees are:

      Atacama, a company that is developing biomaterials to replace plastics, received the “Most Innovative” award and $5,000. The company accelerates the adoption of renewable and sustainable materials through machine learning and robotics, ensuring performance, cost-effectiveness, and environmental impact. Its founders are Paloma Gonzalez-Rojas PhD ’21, Jose Tomas Dominguez, and Jose Antonio Gonzalez.
      Grain Box, a startup focusing on optimizing the post-harvest supply chain for smallholder farmers in rural India, was awarded “Greatest Impact” and a $5,000 award. Its founders are Mona Vijaykumar SMArchS ’22 and T.R. (Radha) Radhakrishnan.
      Lamarr.AI, which offers an autonomous solution for rapid building envelope diagnostics using AI and cloud computing, was recognized for “Best Presentation” and awarded $2,500. Its founders are Norhan Bayomi PhD ’22, Tarek Rakha, PhD ’15, and John E. Fernandez ’85, professor and director of the MIT Environmental Solutions Initiative.
      Honorable Mention: “News Detective,” a platform combining moderated, professional fact-checking and AI to fight misinformation on social media, created by rising senior Ilana Strauss.
      Honorable Mention: “La Firme,” which digitizes architectural services to reach families who self-build their homes in Latin America, created by Mora Orensanz MCP ’21, Fiorella Belli Ferro MCP ’21, and rising senior Raul Briceno Brignole.
      Following the award ceremony, Rosenzweig told the students that the process was not yet over because MITdesignX faculty and staff would always be available to continue guiding and supporting their journeys as they launch and grow their ventures.

      “You’re going to become alumni of MITdesignX,” he said. “You’re going to be joining over 50 teams that are working around the world, making an impact. They’re being recognized as leaders in innovation. They’re being recognized by investors who are helping them make an impact. This is your next step.” More
