      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

      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.

      Doubling down on sustainability innovation in Kendall Square

      by

      From its new headquarters in Cambridge’s Kendall Square, The Engine is investing in a number of “tough tech” startups seeking to transform the world’s energy systems. A few blocks away, the startup Inari is using gene editing to improve seeds’ resilience to climate change. On the MIT campus nearby, researchers are working on groundbreaking innovations to meet the urgent challenges our planet faces.

      Kendall Square is known as the biotech capital of the world, but as the latest annual meeting of the Kendal Square Association (KSA) made clear, it’s also a thriving hub of sustainability-related innovation.

      The Oct. 20 event, which began at MIT’s Welcome Center before moving to the MIT Museum for a panel discussion, brought together professionals from across Cambridge’s prolific innovation ecosystem — not just entrepreneurs working at startups, but also students, restaurant and retail shop owners, and people from local nonprofits.

      Titled “[Re] Imagining a Sustainable Future,” the meeting highlighted advances in climate change technologies that are afoot in Kendall Square, to help inspire and connect the community as it works toward common sustainability goals.

      “Our focus is on building a better future together — and together is the most important word there,” KSA Executive Director Beth O’Neill Maloney said in her opening remarks. “This is an incredibly innovative ecosystem and community that’s making changes that affect us here in Kendall Square and far, far beyond.”

      The pace of change

      The main event of the evening was a panel discussion moderated by Lee McGuire, the chief communications officer of the Broad Institute of MIT and Harvard. The panel featured Stuart Brown, chief financial officer at Inari; Emily Knight, chief operating officer at The Engine; and Joe Higgins, vice president for campus services and stewardship at MIT.

      “Sustainability is obviously one of the most important — if not the most important — challenge facing us as a society today,” said McGuire, opening the discussion. “Kendall Square is known for its work in biotech, life sciences, AI, and climate, and the more we dug into it the more we realized how interconnected all of those things are. The talent in Kendall Square wants to work on problems relevant for humanity, and the tools and skills you need for that can be very similar depending on the problem you’re working on.”

      Higgins, who oversees the creation of programs to reduce MIT’s environmental impact and improve the resilience of campus operations, focused on the enormity of the problem humanity is facing. He showed the audience a map of the U.S. power grid, with power plants and transmission lines illuminated in a complex web across the country, to underscore the scale of electrification that will be needed to mitigate the worst effects of climate change.

      “The U.S. power grid is the largest machine ever made by mankind,” Higgins said. “It’s been developed over 100 years; it has 7,000 generating plants that feed into it every day; it has 7 million miles of cable and wires; there are transformers and substations; and it lives in every single one of your walls. But people don’t think about it that much.”

      Many cities, states, and organizations like MIT have made commitments to shift to 100 percent clean energy in coming decades. Higgins wanted the audience to try to grasp what that’s going to take.

      “Hundreds of millions of devices and equipment across the planet are going to have to be swapped from fossil fuel to electric-based,” Higgins said. “Our cars, appliances, processes in industry, like making steel and concrete, are going to need to come from this grid. It’ll need to undergo a major modernization and transformation. The good news is it’s already changing.”

      Multiple panelists pointed to developments like the passing of the Inflation Reduction Act to show there was progress being made in reaching urgent sustainability goals.

      “There is a tide change coming, and it’s not only being driven by private capital,” Knight said. “There’s a huge opportunity here, and it’s a really important part of this [Kendall Square] ecosystem.”

      Chief among the topics of discussion was technology development. Even as leaders implement today’s technologies to decarbonize, people in Kendall Square keep a close eye on the new tech being developed and commercialized nearby.

      “I was trying to think about where we are with gene editing,” Brown said. “CRISPR’s been around for 10 years. Compare that to video games. Pong was the first video game when it came out in 1972. Today you have Chess.com using artificial intelligence to power chess games. On gene editing and a lot of these other technologies, we’re much closer to Pong than we are to where it’s going to be. We just can’t imagine today the technology changes we’re going to see over the next five to 10 years.”

      In that regard, Knight discussed some of the promising portfolio companies of The Engine, which invests in early stage, technologically innovative companies. In particular, she highlighted two companies seeking to transform the world’s energy systems with entirely new, 100 percent clean energy sources. MIT spinout Commonwealth Fusion Systems is working on nuclear fusion reactors that could provide abundant, safe, and constant streams of clean energy to our grids, while fellow MIT spinout Quaise Energy is seeking to harvest a new kind of deep geothermal energy using millimeter wave drilling technology.

      “All of our portfolio companies have a focus on sustainability in one way or another,” Knight said. “People who are working on these very hard technologies will change the world.”

      Knight says the kind of collaboration championed by the KSA is important for startups The Engine invests in.

      “We know these companies need a lot of people around them, whether from government, academia, advisors, corporate partners, anyone who can help them on their path, because for a lot of them this is a new path and a new market,” Knight said.

      Reasons for hope

      The KSA is made up of over 150 organizations across Kendall Square. From major employers like Sanofi, Pfizer, MIT, and the Broad Institute to local nonprofit organizations, startups, and independent shops and restaurants, the KSA represents the entire Kendall ecosystem.

      O’Neill Maloney celebrated a visible example of sustainability in Kendall Square early on by the Charles River Conservancy, which has built a floating wetland designed to naturally remove harmful algae blooms from Charles River.

      Other examples of sustainability work in the neighborhood can be found at MIT. Under its “Fast Forward” climate action plan, the Institute has set a goal of eliminating direct emissions from its campus by 2050, including a near-term milestone of achieving net-zero emissions by 2026. Since 2014, when MIT launched a five-year plan for action on climate change, net campus emissions have already been cut by 20 percent by making its campus buildings more energy efficient, transitioning to electric vehicles, and enabling large-scale renewable energy projects, among other strategies.

      In the face of a daunting global challenge, such milestones are reason for optimism.

      “If anybody’s going to be able to do this [shift to 100 percent clean energy] and show how it can be done at an urban, city scale, it’s probably MIT and the city of Cambridge,” McGuire said. “We have a lot of good ingredients to figure this out.”

      Throughout the night, many speakers, attendees, and panelists echoed that sentiment. They said they see plenty of reasons for hope.

      “I’m absolutely optimistic,” Higgins said. “I’m seeing utility companies working with businesses working with regulators — people are coming together on this topic. And one of these new technologies being commercialized is going to change things before 2030, whether its fusion, deep geothermal, small modular nuclear reactors, the technology is just moving so quickly.” More

      Making hydrogen power a reality

      by

      For decades, government and industry have looked to hydrogen as a potentially game-changing tool in the quest for clean energy. As far back as the early days of the Clinton administration, energy sector observers and public policy experts have extolled the virtues of hydrogen — to the point that some people have joked that hydrogen is the energy of the future, “and always will be.”

      Even as wind and solar power have become commonplace in recent years, hydrogen has been held back by high costs and other challenges. But the fuel may finally be poised to have its moment. At the MIT Energy Initiative Spring Symposium — entitled “Hydrogen’s role in a decarbonized energy system” — experts discussed hydrogen production routes, hydrogen consumption markets, the path to a robust hydrogen infrastructure, and policy changes needed to achieve a “hydrogen future.”

      During one panel, “Options for producing low-carbon hydrogen at scale,” four experts laid out existing and planned efforts to leverage hydrogen for decarbonization. 

      “The race is on”

      Huyen N. Dinh, a senior scientist and group manager at the National Renewable Energy Laboratory (NREL), is the director of HydroGEN, a consortium of several U.S. Department of Energy (DOE) national laboratories that accelerates research and development of innovative and advanced water splitting materials and technologies for clean, sustainable, and low-cost hydrogen production.

      For the past 14 years, Dinh has worked on fuel cells and hydrogen production for NREL. “We think that the 2020s is the decade of hydrogen,” she said. Dinh believes that the energy carrier is poised to come into its own over the next few years, pointing to several domestic and international activities surrounding the fuel and citing a Hydrogen Council report that projected the future impacts of hydrogen — including 30 million jobs and $2.5 trillion in global revenue by 2050.

      “Now is the time for hydrogen, and the global race is on,” she said.

      Dinh also explained the parameters of the Hydrogen Shot — the first of the DOE’s “Energy Earthshots” aimed at accelerating breakthroughs for affordable and reliable clean energy solutions. Hydrogen fuel currently costs around $5 per kilogram to produce, and the Hydrogen Shot’s stated goal is to bring that down by 80 percent to $1 per kilogram within a decade.

      The Hydrogen Shot will be facilitated by $9.5 billion in funding for at least four clean hydrogen hubs located in different parts of the United States, as well as extensive research and development, manufacturing, and recycling from last year’s bipartisan infrastructure law. Still, Dinh noted that it took more than 40 years for solar and wind power to become cost competitive, and now industry, government, national lab, and academic leaders are hoping to achieve similar reductions in hydrogen fuel costs over a much shorter time frame. In the near term, she said, stakeholders will need to improve the efficiency, durability, and affordability of hydrogen production through electrolysis (using electricity to split water) using today’s renewable and nuclear power sources. Over the long term, the focus may shift to splitting water more directly through heat or solar energy, she said.

      “The time frame is short, the competition is intense, and a coordinated effort is critical for domestic competitiveness,” Dinh said.

      Hydrogen across continents

      Wambui Mutoru, principal engineer for international commercial development, exploration, and production international at the Norwegian global energy company Equinor, said that hydrogen is an important component in the company’s ambitions to be carbon-neutral by 2050. The company, in collaboration with partners, has several hydrogen projects in the works, and Mutoru laid out the company’s Hydrogen to Humber project in Northern England. Currently, the Humber region emits more carbon dioxide than any other industrial cluster in the United Kingdom — 50 percent more, in fact, than the next-largest carbon emitter.   

      “The ambition here is for us to deploy the world’s first at-scale hydrogen value chain to decarbonize the Humber industrial cluster,” Mutoru said.

      The project consists of three components: a clean hydrogen production facility, an onshore hydrogen and carbon dioxide transmission network, and offshore carbon dioxide transportation and storage operations. Mutoru highlighted the importance of carbon capture and storage in hydrogen production. Equinor, she said, has captured and sequestered carbon offshore for more than 25 years, storing more than 25 million tons of carbon dioxide during that time.

      Mutoru also touched on Equinor’s efforts to build a decarbonized energy hub in the Appalachian region of the United States, covering territory in Ohio, West Virginia, and Pennsylvania. By 2040, she said, the company’s ambition is to produce about 1.5 million tons of clean hydrogen per year in the region — roughly equivalent to 6.8 gigawatts of electricity — while also storing 30 million tons of carbon dioxide.

      Mutoru acknowledged that the biggest challenge facing potential hydrogen producers is the current lack of viable business models. “Resolving that challenge requires cross-industry collaboration, and supportive policy frameworks so that the market for hydrogen can be built and sustained over the long term,” she said.

      Confronting barriers

      Gretchen Baier, executive external strategy and communications leader for Dow, noted that the company already produces hydrogen in multiple ways. For one, Dow operates the world’s largest ethane cracker, in Texas. An ethane cracker heats ethane to break apart molecular bonds to form ethylene, with hydrogen one of the byproducts of the process. Also, Baier showed a slide of the 1891 patent for the electrolysis of brine water, which also produces hydrogen. The company still engages in this practice, but Dow does not have an effective way of utilizing the resulting hydrogen for their own fuel.

      “Just take a moment to think about that,” Baier said. “We’ve been talking about hydrogen production and the cost of it, and this is basically free hydrogen. And it’s still too much of a barrier to somewhat recycle that and use it for ourselves. The environment is clearly changing, and we do have plans for that, but I think that kind of sets some of the challenges that face industry here.”

      However, Baier said, hydrogen is expected to play a significant role in Dow’s future as the company attempts to decarbonize by 2050. The company, she said, plans to optimize hydrogen allocation and production, retrofit turbines for hydrogen fueling, and purchase clean hydrogen. By 2040, Dow expects more than 60 percent of its sites to be hydrogen-ready.

      Baier noted that hydrogen fuel is not a “panacea,” but rather one among many potential contributors as industry attempts to reduce or eliminate carbon emissions in the coming decades. “Hydrogen has an important role, but it’s not the only answer,” she said.

      “This is real”

      Colleen Wright is vice president of corporate strategy for Constellation, which recently separated from Exelon Corporation. (Exelon now owns the former company’s regulated utilities, such as Commonwealth Edison and Baltimore Gas and Electric, while Constellation owns the competitive generation and supply portions of the business.) Wright stressed the advantages of nuclear power in hydrogen production, which she said include superior economics, low barriers to implementation, and scalability.

      “A quarter of emissions in the world are currently from hard-to-decarbonize sectors — the industrial sector, steel making, heavy-duty transportation, aviation,” she said. “These are really challenging decarbonization sectors, and as we continue to expand and electrify, we’re going to need more supply. We’re also going to need to produce clean hydrogen using emissions-free power.”

      “The scale of nuclear power plants is uniquely suited to be able to scale hydrogen production,” Wright added. She mentioned Constellation’s Nine Mile Point site in the State of New York, which received a DOE grant for a pilot program that will see a proton exchange membrane electrolyzer installed at the site.

      “We’re very excited to see hydrogen go from a [research and development] conversation to a commercial conversation,” she said. “We’ve been calling it a little bit of a ‘middle-school dance.’ Everybody is standing around the circle, waiting to see who’s willing to put something at stake. But this is real. We’re not dancing around the edges. There are a lot of people who are big players, who are willing to put skin in the game today.” More

      Migration Summit addresses education and workforce development in displacement

      by

      “Refugees can change the world with access to education,” says Alnarjes Harba, a refugee from Syria who recently shared her story at the 2022 Migration Summit — a first-of-its-kind, global convening to address the challenges that displaced communities face in accessing education and employment.

      At the age of 13, Harba was displaced to Lebanon, where she graduated at the top of her high school class. But because of her refugee status, she recalls, no university in her host country would accept her. Today, Harba is a researcher in health-care architecture. She holds a bachelor’s degree from Southern New Hampshire University, where she was part of the Global Education Movement, a program providing refugees with pathways to higher education and work.

      Like many of the Migration Summit’s participants, Harba shared her story to call attention not only to the barriers to refugee education, but also to the opportunities to create more education-to-employment pathways like MIT Refugee Action Hub’s (ReACT) certificate programs for displaced learners.

      Organized by MIT ReACT, the MIT Abdul Latif Jameel World Education Lab (J-WEL), Na’amal, Karam Foundation, and Paper Airplanes, the Migration Summit sought to center the voices and experiences of those most directly impacted by displacement — both in narratives about the crisis and in the search for solutions. Themed “Education and Workforce Development in Displacement,” this year’s summit welcomed more than 900 attendees from over 30 countries, to a total of 40 interactive virtual sessions led by displaced learners, educators, and activists working to support communities in displacement.

      Sessions highlighted the experiences of refugees, migrants, and displaced learners, as well as current efforts across the education and workforce development landscape, ranging from pK-12 initiatives to post-secondary programs, workforce training to entrepreneurship opportunities.

      Overcoming barriers to access

      The vision for the Migration Summit developed, in part, out of the need to raise more awareness about the long-standing global displacement crisis. According to the United Nations High Commissioner for Refugees (UNHCR), 82.4 million people worldwide today are forcibly displaced, a figure that doesn’t include the estimated 12 million people who have fled their homes in Ukraine since February.

      “Refugees not only leave their countries; they leave behind a thousand memories, their friends, their families,” says Mondiant Dogon, a human rights activist, refugee ambassador, and author who gave the Migration Summit’s opening keynote address. “Education is the most important thing that can happen to refugees. In that way, we can leave behind the refugee camps and build our own independent future.”

      Yet, as the stories of the summit’s participants highlight, many in displacement have lost their livelihoods or had their education disrupted — only to face further challenges when trying to access education or find work in their new places of residence. Obstacles range from legal restrictions, language and cultural barriers, and unaffordable costs to lack of verifiable credentials. UNHCR estimates that only 5 percent of refugees have access to higher education, compared to the global average of 39 percent.

      “There is another problem related to forced displacement — dehumanization of migrants,” says Lina Sergie Attar, the founder and CEO of Karam Foundation. “They are unjustly positioned as enemies, as a threat.”

      But as Blein Alem, an MIT ReACT alum and refugee from Eritrea, explains, “No one chooses to be a refugee — it just occurs. Whether by conflict, war, human rights violations, just because you have refugee status does not mean that you are not willing to make a change in your life and access to education and work.” Several participants, including Alem, shared that, even with a degree in hand, their refugee status limited their ability to work in their new countries of residence.

      Displaced communities face complex and structural challenges in accessing education and workforce development opportunities. Because of the varying and vast effects of displacement, efforts to address these challenges range in scale and focus and differ across sectors. As Lorraine Charles, co-founder and director of Na’amal, noted in the Migration Summit’s closing session, many organizations find themselves working in silos, or even competing with each other for funding and other resources. As a result, solution-making has been fragmented, with persistent gaps between different sectors that are, in fact, working toward the same goals.

      Imagining a modular, digital, collaborative approach

      A key takeaway from the month’s discussions, then, is the need to rethink the response to refugee education and workforce challenges. During the session, “From Intentions to Impact: Decolonizing Refugee Response,” participants emphasized the systemic nature of these challenges. Yet formal responses, such as the 1951 Refugee Convention, have been largely inadequate — in some instances even oppressing the communities they’re meant to support, explains Sana Mustafa, director of partnership and engagement for Asylum Access.

      “We have the opportunity to rethink how we are handling the situation,” Mustafa says, calling for more efforts to include refugees in the design and development of solutions.

      Presenters also agreed that educational institutions, particularly universities, could play a vital role in providing more pathways for refugees and displaced learners. Key to this is rethinking the structure of education itself, including its delivery.

      “The challenge right now is that degrees are monolithic,” says Sanjay Sarma, vice president for MIT Open Learning, who gave the keynote address on “Pathways to Education, Livelihood, and Hope.” “They’re like those gigantic rocks at Stonehenge or in other megalithic sites. What we need is a much more granular version of education: bricks. Bricks were invented several thousand years ago, but we don’t really have that yet formally and extensively in education.”

      “There is no way we can accommodate thousands and thousands of refugees face-to-face,” says Shai Reshef, the founder and president of University of the People. “The only path is a digital one.”

      Ultimately, explains Demetri Fadel of Karam Foundation, “We really need to think about how to create a vision of education as a right for every person all around the world.”

      Underlying many of the Migration Summit’s conclusions is the awareness that there is still much work to be done. However, as the summit’s co-chair Lana Cook said in her closing remarks, “This was not a convening of despair, but one about what we can build together.”

      The summit’s organizers are currently putting together a public report of the key findings that have emerged from the month’s conversations, including recommendations for thematic working groups and future Migration Summit activities. More

      “The world needs your smarts, your skills,” Ngozi Okonjo-Iweala tells MIT’s Class of 2022

      by

      On a clear warm day, the MIT graduating class of 2022 gathered in Killian Court for the first in-person commencement exercises in three years, after two years of online ceremonies due to the Covid-19 pandemic.

      Ngozi Okonjo-Iweala MCP ’78, PhD ’81, director-general of the World Trade Organization, delivered the Commencement address, stressing the global need for science-informed policy to address problems of climate change, pandemics, international security, and wealth disparities. She told the graduates: “In these uncertain times, in this complex world in which you are entering, you need not be so daunted, if you can search for the opportunities hidden in challenges.” She urged them to go “into the world to embrace the opportunities to serve.”

      An expert in global finance, economics, and international development, Okonjo-Iweala is the first woman and first African to lead the WTO. She earned a master’s degree in city planning from MIT in 1978, and a PhD in regional economics and development in 1981.

      Okonjo-Iweala began her address by paying tribute to MIT President L. Rafael Reif, who earlier this semester announced plans to end his decade-long tenure in that role. Calling this a “bittersweet day” because of his departure, she honored “his academic, institutional, and thought leadership of these past 10 years.”

      She spoke warmly of the way MIT had helped her while she was a graduate student struggling to pay the bills. She was assured that the Institute would do whatever was needed to make sure she could complete her studies, she recalled, saying, “They had my back.” Noting that this year’s graduating class had their own educational journeys challenged by the global pandemic, she described how her own early education was interrupted for three years by civil war in her home country of Nigeria. She also noted the recent tragic shootings in Uvalde, Texas, saying that “I feel grief as a mother and a grandmother.”

      “MIT has helped make me who I am today,” she said. “My parents made it clear to me that education was a privilege, and that with that privilege comes responsibility — the responsibility to use it for others, not just for yourself.”

      She said that what the world needs in this time of multiple global challenges, including Covid-19, climate change, public health, and international security, is an approach “combining science, social science, and public policy, to meet the challenges of our future.”

      Friday’s Commencement ceremony celebrated the 1,099 undergraduate and 2,590 graduate students receiving MIT diplomas this year.

      Okonjo-Iweala, who was formerly head of the World Bank, said that “a common thread running through many of these challenges is the central role for science,” and she stressed the need for technological innovation to address the global problems facing humanity. “New inventions and new ways of doing things will have an impact, mainly to the extent they are scaled up across the dividing lines of income and geography,” she said.

      “We don’t just need vaccines,” she continued. “We need shots in arms across the world, to be safe. We need new renewable technologies diffused not just in rich countries to fight climate change, but also in poor ones. We need new agricultural technologies built to local conditions and culture, if we’re to fight hunger. In other words, we need innovation. But we also need access, equity, diffusion.”

      In the case of the global response to the pandemic, she noted that only 17 percent of people in Africa and 13 percent of people in low-income countries have been fully vaccinated, compared to 75 percent of people in high income countries. “Since we all know that no one is safe until everyone is safe, the risk of more dangerous variants and pathogens remains real because of this public policy lapse and the lack of timely international cooperation,” she said.

      As for climate change, she pointed out that the world somehow managed to come up with $14 trillion to address the Covid-19 pandemic but has not managed to fulfill the pledges nations made to provide $100 billion to help less-developed nations build renewable energy solutions.

      To address these global challenges, she told the new graduates, “the world needs your smarts, your skills, your adaptability, and the great training you have received here at MIT. The world needs you for innovation, for policymaking, for connecting the dots so that implementation can actually happen.”

      President Reif, in his charge to the graduates, urged the assembled crowd to shout out a loud “thank you!” to all family, professors, friends, and other who helped them reach today’s milestone. He pointed out that research, including from MIT’s Department of Brain and Cognitive Sciences, shows that “simply expressing gratitude does wonderful things to your brain. It gets different parts of your brain to act in a synchronized way. It lights up reward pathways!”

      “All of us could use a reliable device for feeling better. So now, thanks to brain science, Course 9, you have one! The Gratitude Amplifier is unbreakable. Its battery never dies, it will never try to sell you anything, you can use it every day, forever — and it’s free!”

      He recalled the example of the way students banded together to create a new space for relaxation on campus, now known as the Banana Lounge, a central location where students could relax with free coffee and bananas. “The students have done this all essentially themselves, applying their skills and the most delightful MIT values.” The project has already distributed a half-million bananas, he said, and produced a “wonderful, tropical, perfectly improbable new MIT institution.”

      He urged the graduating students to work to “make the world a little more like MIT. More daring and more passionate. More rigorous, inventive and ambitious. More humble, more respectful, more generous, more kind.” And, he added, “try always to share your bananas!”

      Adam Joseph “AJ” Miller, president of the Graduate Student Council, said, “Today marks the end of a chapter, the culmination of so many late nights, to forge lifelong friendships, to hold onto new experiences, to shape our dreams.” He added that “Something I heard a lot about when I first got here was all the doubt so many of us had in ourselves. I can say unequivocally today though, there are no impostors before me. Nobody sits where you sit by accident. You’re all now graduates of MIT, carrying on an incredibly impressive history.”

      Miller urged his fellow students to “stay confident in yourselves because of the challenges you’ve overcome. Be courageous in trying, because failure is learning and investing in each other.”

      Temiloluwa Omitoogun, president of the Class of 2022, told his classmates, “MIT is hard. MIT during an unprecedented pandemic is even harder, but we did it. Even if you don’t realize it, this is a huge accomplishment.” He added that “it’s sad that we’re all parting ways at the moment, but I’m even more excited than sad. I’m excited to see what more you all will accomplish. I look out and I don’t just see friends and classmates. I see future leaders, people who will change the world. I’m going to try my best to keep up and change the world too.”

      Later in the day, in a separate ceremony on Briggs Field, each of the members of the undergraduate Class of 2022 had a chance to hear their names read aloud as they walked across the stage to receive their diplomas. Right before this presentation, senior and physics and mathematics major Quinn Brodsky performed a heartful rendition of “Hypotheticals” by Lake Street Dive.

      Addressing the graduating seniors, Chancellor Melissa Nobles urged them to “absorb and relish this celebration of what you’ve achieved during your transformative time at MIT. How much you have grown, academically, professionally and personally!” She added that “the lifelong friends and mentors you found here are the people who I know will continue to be sources of encouragement, support, and inspiration as you make your way in the world.”

      Recalling the way the pandemic altered their academic careers, she said “you should know now that you can handle whatever life throws your way. Never forget that you are stronger and more resilient than you think you are.” She added, “hold on to the way this pandemic has put certain things into perspective. Time with people we care about is precious. So are our health and wellbeing, and the health and wellbeing of the ones we love. Looking out for others and feeling a sense of shared responsibility for the common good are paramount.”

      Nobles concluded that “your journey into the future holds countless possibilities, risks, joys, rewards, sometimes failures, and always surprises. … We wish you well on the road ahead.” More

      Lama Willa Baker challenges MIT audience to look beyond technology to solve the climate crises

      by

      Buddhist teacher Willa Blythe Baker called for an “embodied revolution,” in speaking to an MIT audience on May 5, to create a world in which we realize we are connected and interdependent with each other and with our natural environment. She envisioned a world in which we always ask of every question: “How will this affect our bodies, trees, plants, mosses, water, air around us?”

      Authorized as a dharma teacher and lineage holder (lama) in the Kagyu lineage of Tibetan Buddhism, Baker holds a PhD in religion form Harvard University and is founder and spiritual co-director of the Natural Dharma Fellowship in Boston. As experts warn of warming oceans, rising sea levels, turbulent weather, mass extinctions, droughts, hunger, and global pandemics, she said, “Much is made of what we must do, but little is made of how we must live and who we must become”

      The climate crisis has been “framed as a set of problems that need to be solved through intellectual ingenuity, engineering, and technology. These solutions are critical, but they do not require grappling with the underlying issue … They do not look beyond doing, to being.’“

      Part of the problem, Baker pointed out, is that in discussing climate change, we frequently approach it in terms of what we must give up to live more sustainably — but not in terms of what we gain by living simply and mindfully.

      Disembodiment

      Baker outlined her view that “disembodiment” is a key underlying cause of the global environmental crisis. This disembodied state causes us to feel separate from our ecosystem, and from one another, and from our own bodies, leading to a state of constant worry about the past or the future, and to a constant desire or ambition for more. Disembodiment  is the state of being “up in the head” and out of touch with the body, and being disconnected from the here and now.

      The climate crisis, Baker put forward, is in part a result of society’s long journey away from the embodied ways of being in earlier agrarian societies in which there was a more intimate relationship between humans and their natural world.

      The contemplative tradition

      Baker said the contemplative perspective, and the practices of meditation and mindfulness, have much to offer climate activists. Rather than viewing meditation, prayer, or contemplation as passive acts, these practices are active pursuits, according to Baker, as “engagements of attention and embodiment that steward novel ways of knowing and being.”

      She explained further how an “embodied contemplative perspective” re-frames the climate crisis. Instead of viewing the crisis as external, the climate crisis calls for us to look inward to our motivations and values. “It is asking us to inquire into who and what we are, not just what we do.” Rather than seeing ourselves as “stewards” of the planet, we should see ourselves as part of the planet.

      “The idea of embodiment gets us to explore who we are in the deepest sense … Embodiment is a journey from our isolated sense of separateness, our sense of limited cognitive identity, back to the body and senses, back to our animal wisdom, back to the earthly organic identity of being bound by gravity.”

      Baker pointed to the central Buddhist tenet that we live with the illusion of separateness, and, she said, “the task of this human life is to see beyond the veil of that illusion.”

      Embodiment will bring us “back to the body and senses; back to our animal wisdom; back to the earthly organic identity of being bound by gravity. These wisdoms remind us of who we are — that we are of the Earth.”

      How much is enough?

      A lively discussion was held following the presentation. One audience member asked how to reconcile the idea of looking to the body for wisdom, when some of the climate crisis is fueled by our need for bodily comfort. Baker replied, “We have started to associate comfort with plenty … That’s a point of reflection. How much is enough?” She said that part of the Buddhist path is the cultivation of knowing that whatever you have is enough.

      One MIT student studying mechanical engineering asked how to reconcile these ideas with a capitalistic society. He pointed out that “a lot of industry is driven by the need to accumulate more capital … Every year, you want to increase your balance sheet … How do you tell companies that what you have is enough?”

      Baker agreed that that our current economic system constantly encourages us to want “more.” “Human happiness is at stake, in addition to our planet’s survival. If we’re told that the ‘next thing’ will make us happy, we will be seeking happiness externally. I think the system will change eventually. I don’t think we have any choice. The planet cannot sustain a world where we’re producing and producing more and more stuff for us to need and want.”

      One audience member asked how to meet the challenge of being embodied in our busy world. Baker said that “embodiment and disembodiment is a continuum. Sometimes we have to be in our head. We’re taking a test, or writing a paper. But we can get ‘up there’ so much that we forget we have a body.” She called for ‘bringing your attention down. Pausing and bring attention all the way down, and feeling the Earth below your feet … There’s a calming and centering that comes with coming down and connecting with the Earth below. Being present and grounded and in tune.”

      Baker said the body can show us, “Just here. Just now. Just this.”

      The speaker was introduced by Professor Emma J. Teng, the T.T. and Wei Fong Chao Professor of Asian Civilizations at MIT. This spring, Teng introduced a new class 21G.015 (Introduction to Buddhism, Mindfulness, and Meditation), a half-term subject that met with the class PE.0534 (Fitness and Meditation), taught by Sarah Johnson, so that students learned basic ideas of Buddhism and its history while having a chance to learn and practice mindfulness and meditation techniques.

      This event was the latest in the T.T. and W.F. Chao Distinguished Buddhist Lecture Series. This series engages the rich history of Buddhist thought and ethical action to advance critical dialogues on ethics, humanity, and MIT’s mission “to develop in each member of the MIT community the ability and passion to work wisely, creatively, and effectively for the betterment of humankind.”

      Baker’s books include “Essence of Ambrosia” (2005), “Everyday Dharma”(2009), “The Arts of Contemplative Care” (2012) and “The Wakeful Body” (2021). Her guided meditations can be found here. More

      Solar-powered desalination device wins MIT $100K competition

      by

      The winner of this year’s MIT $100K Entrepreneurship Competition is commercializing a new water desalination technology.

      Nona Desalination says it has developed a device capable of producing enough drinking water for 10 people at half the cost and with 1/10th the power of other water desalination devices. The device is roughly the size and weight of a case of bottled water and is powered by a small solar panel.

      “Our mission is to make portable desalination sustainable and easy,” said Nona CEO and MIT MBA candidate Bruce Crawford in the winning pitch, delivered to an audience in the Kresge Auditorium and online.

      The traditional approach for water desalination relies on a power-intensive process called reverse osmosis. In contrast, Nona uses a technology developed in MIT’s Research Laboratory of Electronics that removes salt and bacteria from seawater using an electrical current.

      “Because we can do all this at super low pressure, we don’t need the high-pressure pump [used in reverse osmosis], so we don’t need a lot of electricity,” says Crawford, who co-founded the company with MIT Research Scientist Junghyo Yoon. “Our device runs on less power than a cell phone charger.”

      The founders cited problems like tropical storms, drought, and infrastructure crises like the one in Flint, Michigan, to underscore that clean water access is not just a problem in developing countries. In Houston, after Hurricane Harvey caused catastrophic flooding in 2017, some residents were advised not to drink their tap water for months.

      The company has already developed a small prototype that produces clean drinking water. With its winnings, Nona will build more prototypes to give to early customers.

      The company plans to sell its first units to sailors before moving into the emergency preparedness space in the U.S., which it estimates to be a $5 billion industry. From there, it hopes to scale globally to help with disaster relief. The technology could also possibly be used for hydrogen production, oil and gas separation, and more.

      The MIT $100K is MIT’s largest entrepreneurship competition. It began in 1989 and is organized by students with support from the Martin Trust Center for MIT Entrepreneurship and the MIT Sloan School of Management. Each team must include at least one current MIT student.

      The second-place $25,000 prize went to Inclusive.ly, a company helping people and organizations create a more inclusive environment.

      The company uses conversational artificial intelligence and natural language processing to detect words and phrases that contain bias, and can measure the level of bias or inclusivity in communication.

      “We’re here to create a world where everyone feels invited to the conversation,” said MBA candidate Yeti Khim, who co-founded the company with fellow MBA candidates Joyce Chen and Priya Bhasin.

      Inclusive.ly can scan a range of communications and make suggestions for improvement. The algorithm can detect discrimination, microaggression, and condescension, and the founders say it analyzes language in a more nuanced way than tools like Grammarly.

      The company is currently developing a plugin for web browsers and is hoping to partner with large enterprise customers later this year. It will work with internal communications like emails as well as external communications like sales and marketing material.

      Inclusive.ly plans to sell to organizations on a subscription model and notes that diversity and inclusion is becoming a higher priority in many companies. Khim cited studies showing that lack of inclusion hinders employee productivity, retention, and recruiting.

      “We could all use a little bit of help to create the most inclusive version of ourselves,” Khim said.

      The third-place prize went to RTMicrofluidics, which is building at-home tests for a range of diseases including strep throat, tuberculosis, and mononucleosis. The test is able to detect a host of bacterial and viral pathogens in saliva and provide accurate test results in less than 30 minutes.

      The audience choice award went to Sparkle, which has developed a molecular dye technology that can illuminate tumors, making them easier to remove during surgery.

      This year’s $100K event was the culmination of a process that began last March, when 60 teams applied for the program. Out of that pool, 20 semifinalists were given additional mentoring and support before eight finalists were selected to pitch.

      The other finalist teams were:

      Astrahl, which is developing high resolution and affordable X-ray systems by integrating nanotechnologies with scintillators;

      Encreto Therapeutics, which is discovering medications to satiate appetite for people with obesity;

      Iridence, which has patented a biomaterial to replace minerals like mica as a way to make the beauty industry more sustainable; and

      Mantel, which is developing a liquid material for more efficient carbon removal that operates at high temperatures. More
