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

    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

    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

    Material designed to improve power plant efficiency wins 2022 Water Innovation Prize

    The winner of this year’s Water Innovation Prize is a company commercializing a material that could dramatically improve the efficiency of power plants.

    The company, Mesophase, is developing a more efficient power plant steam condenser that leverages a surface coating developed in the lab of Evelyn Wang, MIT’s Ford Professor of Engineering and the head of the Department of Mechanical Engineering. Such condensers, which convert steam into water, sit at the heart of the energy extraction process in most of the world’s power plants.

    In the winning pitch, company founders said they believe their low-cost, durable coating will improve the heat transfer performance of such condensers.

    “What makes us excited about this technology is that in the condenser field, this is the first time we’ve seen a coating that can last long enough for industrial applications and be made with a high potential to scale up,” said Yajing Zhao SM ’18, who is currently a PhD candidate in mechanical engineering at MIT. “When compared to what’s available in academia and industry, we believe you’ll see record performance in terms of both heat transfer and lifetime.”

    In most power plants, condensers cool steam to turn it into water. The pressure change caused by that conversion creates a vacuum that pulls steam through a turbine. Mesophase’s patent-pending surface coating improves condensers’ ability to transfer heat, thus allowing operators to extract power more efficiently.

    Based on lab tests, the company predicts it can increase power plant output by up to 7 percent using existing infrastructure. Because steam condensers are used around the world, this advance could help increase global electricity production by 500 terawatt hours per year, which is equivalent to the electricity supply for about 1 billion people.

    The efficiency gains will also lead to less water use. Water sent from cooling towers is a common means of keeping condensers cool. The company estimates its system could reduce fresh water withdrawals by the equivalent of what is used by 50 million people per year.

    After running pilots, the company believes the new material could be installed in power plants during the regularly scheduled maintenance that occurs every two to five years. The company is also planning to work with existing condenser manufacturers to get to market faster.

    “This all works because a condenser with our technology in it has significantly more attractive economics than what you find in the market today,” says Mesophase’s Michael Gangemi, an MBA candidate at MIT’s Sloan School of Management.

    The company plans to start in the U.S. geothermal space, where Mesophase estimates its technology is worth about $800 million a year.

    “Much of the geothermal capacity in the U.S. was built in the ’50s and ’60s,” Gangemi said. “That means most of these plants are operating way below capacity, and they invest frequently in technology like ours just to maintain their power output.”

    The company will use the prize money, in part, to begin testing in a real power plant environment.

    “We are excited about these developments, but we know that they are only first steps as we move toward broader energy applications,” Gangemi said.

    MIT’s Water Innovation Prize helps translate water-related research and ideas into businesses and impact. Each year, student-led finalist teams pitch their innovations to students, faculty, investors, and people working in various water-related industries.

    This year’s event, held in a virtual hybrid format in MIT’s Media Lab, included five finalist teams. The second-place $15,000 award was given to Livingwater Systems, which provides portable rainwater collection and filtration systems to displaced and off-grid communities.

    The company’s product consists of a low-cost mesh that goes on roofs to collect the water and a collapsible storage unit that incorporates a sediment filter. The water becomes drinkable after applying chlorine tablets to the storage unit.

    “Perhaps the single greatest attraction of our units is their elegance and simplicity,” Livingwater CEO Joshua Kao said in the company’s pitch. “Anyone can take advantage of their easy, do-it-yourself setup without any preexisting knowhow.”

    The company says the system works on the pitched roofs used in many off-grid settlements, refugee camps, and slums. The entire unit fits inside a backpack.

    The team also notes existing collection systems cost thousands of dollars, require expert installation, and can’t be attached to surfaces like tents. Livingwater is aiming to partner with nongovernmental organizations and nonprofit entities to sell its systems for $60 each, which would represent significant cost savings when compared to alternatives like busing water into settlements.

    The company will be running a paid pilot with the World Food Program this fall.

    “Support from MIT will be crucial for building the core team on the ground,” said Livingwater’s Gabriela Saade, a master’s student in public policy at the University of Chicago. “Let’s begin to realize a new era of water security in Latin America and across the globe.”

    The third-place $10,000 prize went to Algeon Materials, which is creating sustainable and environmentally friendly bioplastics from kelp. Algeon also won the $5,000 audience choice award for its system, which doesn’t require water, fertilizer, or land to produce.

    The other finalists were:

    Flowless, which uses artificial intelligence and an internet of things (IoT) platform to detect leaks and optimize water-related processes to reduce waste;
    Hydrologistics Africa Ltd, a platform to help consumers and utilities manage their water consumption; and
    Watabot, which is developing autonomous, artificial intelligence-powered systems to monitor harmful algae in real time and predict algae activity.

    Each year the Water Innovation Prize, hosted by the MIT Water Club, awards up to $50,000 in grants to teams from around the world. This year’s program received over 50 applications. A group of 20 semifinalist teams spent one month working with mentors to refine their pitches and business plans, and the final field of finalists received another month of mentorship.

    The Water Innovation Prize started in 2015 and has awarded more than $275,000 to 24 different teams to date. More

    How can we reduce the carbon footprint of global computing?

    The voracious appetite for energy from the world’s computers and communications technology presents a clear threat for the globe’s warming climate. That was the blunt assessment from presenters in the intensive two-day Climate Implications of Computing and Communications workshop held on March 3 and 4, hosted by MIT’s Climate and Sustainability Consortium (MCSC), MIT-IBM Watson AI Lab, and the Schwarzman College of Computing.

    The virtual event featured rich discussions and highlighted opportunities for collaboration among an interdisciplinary group of MIT faculty and researchers and industry leaders across multiple sectors — underscoring the power of academia and industry coming together.

    “If we continue with the existing trajectory of compute energy, by 2040, we are supposed to hit the world’s energy production capacity. The increase in compute energy and demand has been increasing at a much faster rate than the world energy production capacity increase,” said Bilge Yildiz, the Breene M. Kerr Professor in the MIT departments of Nuclear Science and Engineering and Materials Science and Engineering, one of the workshop’s 18 presenters. This computing energy projection draws from the Semiconductor Research Corporations’s decadal report.To cite just one example: Information and communications technology already account for more than 2 percent of global energy demand, which is on a par with the aviation industries emissions from fuel.“We are the very beginning of this data-driven world. We really need to start thinking about this and act now,” said presenter Evgeni Gousev, senior director at Qualcomm.  Innovative energy-efficiency optionsTo that end, the workshop presentations explored a host of energy-efficiency options, including specialized chip design, data center architecture, better algorithms, hardware modifications, and changes in consumer behavior. Industry leaders from AMD, Ericsson, Google, IBM, iRobot, NVIDIA, Qualcomm, Tertill, Texas Instruments, and Verizon outlined their companies’ energy-saving programs, while experts from across MIT provided insight into current research that could yield more efficient computing.Panel topics ranged from “Custom hardware for efficient computing” to “Hardware for new architectures” to “Algorithms for efficient computing,” among others.

    The goal, said Yildiz, is to improve energy efficiency associated with computing by more than a million-fold.“I think part of the answer of how we make computing much more sustainable has to do with specialized architectures that have very high level of utilization,” said Darío Gil, IBM senior vice president and director of research, who stressed that solutions should be as “elegant” as possible.  For example, Gil illustrated an innovative chip design that uses vertical stacking to reduce the distance data has to travel, and thus reduces energy consumption. Surprisingly, more effective use of tape — a traditional medium for primary data storage — combined with specialized hard drives (HDD), can yield a dramatic savings in carbon dioxide emissions.Gil and presenters Bill Dally, chief scientist and senior vice president of research of NVIDIA; Ahmad Bahai, CTO of Texas Instruments; and others zeroed in on storage. Gil compared data to a floating iceberg in which we can have fast access to the “hot data” of the smaller visible part while the “cold data,” the large underwater mass, represents data that tolerates higher latency. Think about digital photo storage, Gil said. “Honestly, are you really retrieving all of those photographs on a continuous basis?” Storage systems should provide an optimized mix of of HDD for hot data and tape for cold data based on data access patterns.Bahai stressed the significant energy saving gained from segmenting standby and full processing. “We need to learn how to do nothing better,” he said. Dally spoke of mimicking the way our brain wakes up from a deep sleep, “We can wake [computers] up much faster, so we don’t need to keep them running in full speed.”Several workshop presenters spoke of a focus on “sparsity,” a matrix in which most of the elements are zero, as a way to improve efficiency in neural networks. Or as Dally said, “Never put off till tomorrow, where you could put off forever,” explaining efficiency is not “getting the most information with the fewest bits. It’s doing the most with the least energy.”Holistic and multidisciplinary approaches“We need both efficient algorithms and efficient hardware, and sometimes we need to co-design both the algorithm and the hardware for efficient computing,” said Song Han, a panel moderator and assistant professor in the Department of Electrical Engineering and Computer Science (EECS) at MIT.Some presenters were optimistic about innovations already underway. According to Ericsson’s research, as much as 15 percent of the carbon emissions globally can be reduced through the use of existing solutions, noted Mats Pellbäck Scharp, head of sustainability at Ericsson. For example, GPUs are more efficient than CPUs for AI, and the progression from 3G to 5G networks boosts energy savings.“5G is the most energy efficient standard ever,” said Scharp. “We can build 5G without increasing energy consumption.”Companies such as Google are optimizing energy use at their data centers through improved design, technology, and renewable energy. “Five of our data centers around the globe are operating near or above 90 percent carbon-free energy,” said Jeff Dean, Google’s senior fellow and senior vice president of Google Research.Yet, pointing to the possible slowdown in the doubling of transistors in an integrated circuit — or Moore’s Law — “We need new approaches to meet this compute demand,” said Sam Naffziger, AMD senior vice president, corporate fellow, and product technology architect. Naffziger spoke of addressing performance “overkill.” For example, “we’re finding in the gaming and machine learning space we can make use of lower-precision math to deliver an image that looks just as good with 16-bit computations as with 32-bit computations, and instead of legacy 32b math to train AI networks, we can use lower-energy 8b or 16b computations.”

    Other presenters singled out compute at the edge as a prime energy hog.“We also have to change the devices that are put in our customers’ hands,” said Heidi Hemmer, senior vice president of engineering at Verizon. As we think about how we use energy, it is common to jump to data centers — but it really starts at the device itself, and the energy that the devices use. Then, we can think about home web routers, distributed networks, the data centers, and the hubs. “The devices are actually the least energy-efficient out of that,” concluded Hemmer.Some presenters had different perspectives. Several called for developing dedicated silicon chipsets for efficiency. However, panel moderator Muriel Medard, the Cecil H. Green Professor in EECS, described research at MIT, Boston University, and Maynooth University on the GRAND (Guessing Random Additive Noise Decoding) chip, saying, “rather than having obsolescence of chips as the new codes come in and in different standards, you can use one chip for all codes.”Whatever the chip or new algorithm, Helen Greiner, CEO of Tertill (a weeding robot) and co-founder of iRobot, emphasized that to get products to market, “We have to learn to go away from wanting to get the absolute latest and greatest, the most advanced processor that usually is more expensive.” She added, “I like to say robot demos are a dime a dozen, but robot products are very infrequent.”Greiner emphasized consumers can play a role in pushing for more energy-efficient products — just as drivers began to demand electric cars.Dean also sees an environmental role for the end user.“We have enabled our cloud customers to select which cloud region they want to run their computation in, and they can decide how important it is that they have a low carbon footprint,” he said, also citing other interfaces that might allow consumers to decide which air flights are more efficient or what impact installing a solar panel on their home would have.However, Scharp said, “Prolonging the life of your smartphone or tablet is really the best climate action you can do if you want to reduce your digital carbon footprint.”Facing increasing demandsDespite their optimism, the presenters acknowledged the world faces increasing compute demand from machine learning, AI, gaming, and especially, blockchain. Panel moderator Vivienne Sze, associate professor in EECS, noted the conundrum.“We can do a great job in making computing and communication really efficient. But there is this tendency that once things are very efficient, people use more of it, and this might result in an overall increase in the usage of these technologies, which will then increase our overall carbon footprint,” Sze said.Presenters saw great potential in academic/industry partnerships, particularly from research efforts on the academic side. “By combining these two forces together, you can really amplify the impact,” concluded Gousev.Presenters at the Climate Implications of Computing and Communications workshop also included: Joel Emer, professor of the practice in EECS at MIT; David Perreault, the Joseph F. and Nancy P. Keithley Professor of EECS at MIT; Jesús del Alamo, MIT Donner Professor and professor of electrical engineering in EECS at MIT; Heike Riel, IBM Fellow and head science and technology at IBM; and Takashi Ando, principal research staff member at IBM Research.

    MIT Energy Conference focuses on climate’s toughest challenges

    This year’s MIT Energy Conference, the largest student-led event of its kind, included keynote talks and panels that tackled some of the thorniest remaining challenges in the global effort to cut back on climate-altering emissions. These include the production of construction materials such as steel and cement, and the role of transportation including aviation and shipping. While the challenges are formidable, approaches incorporating methods such as fusion, heat pumps, energy efficiency, and the use of hydrogen hold promise, participants said.

    The two-day conference, held on March 31 and April 1 for more than 900 participants, included keynote lectures, 14 panel discussions, a fireside chat, networking events, and more. The event this year included the final round of the annual MIT Climate and Energy Prize, whose winning team receives $100,000 and other support. The prize, awarded since 2007, has led to the creation of more than 220 companies and $1.1 billion in investments.

    This year’s winner is a project that hopes to provide an innovative, efficient waterless washing machine aimed at the vast majority of the world’s people, who still do laundry by hand.

    “A truly consequential moment in history”

    In his opening keynote address Fatih Birol, executive director of the International Energy Agency, noted that this year’s conference was taking place during the unprovoked invasion of Ukraine by Russia, a leading gas and oil exporter. As a result, “global oil markets are going through a major turmoil,” he said.

    He said that Russian oil exports are expected to drop by 3 million barrels a day, and that international efforts to release reserves and promote increased production elsewhere will help, but will not suffice. “We have to look to other measures” to make up the shortfall, he said, noting that his agency has produced a 10-point plan of measures to help reduce global demand for oil.

    Europe gets 45 percent of its natural gas from Russia, and the agency also has developed a 10-point plan to help alleviate expected shortages there, including measures to improve energy efficiency in homes and industries, promote renewable heating sources, and postpone retirement of some nuclear plants. But he emphasized that “our goals to reach our climate targets should not be yet another victim of Mr. Putin and his allies.”  Unfortunately, Birol said, “I see that addressing climate change is sliding down in the policy agenda of many governments.”

    But he sees reasons for optimism as well, in terms of the feasibility of achieving the global emissions reduction target, agreed to by countries representing 80 percent of the global economy, of reaching net zero carbon dioxide emissions by 2050. The IEA has developed a roadmap for the entire energy sector to get there, which is now used by many governments as a benchmark, according to Birol.

    In addition, the trend is already clear, he said. “More than 90 percent of all power plants installed in the world [last year] were renewable energy,” mainly solar and wind. And 10 percent of cars sold worldwide last year, and 20 percent in Europe, were electric cars. “Please remember that in 2019 it was only 2 percent!” he said. He also predicted that “nuclear is going to make a comeback in many countries,” both in terms of large plants and newer small modular reactors.

    Birol said that “I hope that the current crisis gives governments the impetus to address the energy security concerns, to reach our climate goals, and … [to] choose the right direction at this very important turning point.”

    The conference’s second day began with keynote talks by Gina McCarthy, national climate advisor at the White House Office of Domestic Climate Policy, and Maria Zuber, MIT’s vice president for research. In her address, Zuber said, “This conference comes at a truly consequential moment in history — a moment that puts into stark relief the enormous risks created by our current fossil-fuel based energy system — risks we cannot continue to accept.”

    She added that “time is not on our side.” To meet global commitments for limiting climate impacts, the world needs to reduce emissions by about half by 2030, and get to net zero by 2050. “In other words, we need to transform our entire global energy system in a few decades,” she said. She cited MIT’s “Fast Forward” climate action plan, issued last year, as presenting the two tracks that the world needs to pursue simultaneously: going as far as possible, as fast as possible, with the tools that exist now, while also innovating and investing in new ideas, technologies, practices, and institutions that may be needed to reach the net-zero goal.

    On the first track, she said, citing an IEA report, “from here until 2040, we can get most of the emissions reductions we need with technologies that are currently available or on the verge of becoming commercially available.” These include electrifying and boosting efficiency in buildings, industry, and transportation; increasing the portion of electricity coming from emissions-free sources; and investing in new infrastructure such as electric vehicle charging stations.

    But more than that is needed, she pointed out. For example, the amount of methane that leaks away into the atmosphere from fossil fuel operations is equivalent to all the natural gas used in Europe’s power sector, Zuber said. Recovering and selling that methane can dramatically reduce global methane emissions, often at little or no cost.

    For the longer run, “we need track-two solutions to decarbonize tough industries like aviation, shipping, chemicals, concrete, and steel,” and to remove carbon dioxide from the atmosphere. She described some of the promising technologies that are in the pipeline. Fusion, for example, has moved from being a scientific challenge to an engineering problem whose solution seems well underway, she said.

    Another important area is food-related systems, which currently account for a third of all global emissions. For example, fertilizer production uses a very energy-intensive process, but work on plants engineered to fix nitrogen directly could make a significant dent.

    These and several other advanced research areas may not all pan out, but some undoubtedly will, and will help curb climate change as well as create new jobs and reduce pollution.

    Though the problems we face are complex, they are not insurmountable, Zuber said. “We don’t need a miracle. What we need is to move along the two tracks I’ve outlined with determination, ingenuity, and fierce urgency.”

    The promise and challenges of hydrogen

    Other conference speakers took on some of the less-discussed but crucial areas that also need to be addressed in order to limit global warming to 1.5 degrees. Heavy transportation, and aviation in particular, have been considered especially challenging. In his keynote address, Glenn Llewellyn, vice president for zero-emission aircraft at Airbus, outlined several approaches his company is working on to develop competitive midrange alternative airliners by 2035 that use either batteries or fuel cells powered by hydrogen. The early-stage designs demonstrate that, contrary to some projections, there is a realistic pathway to weaning that industry from its present reliance on fossil fuel, chiefly kerosene.

    Hydrogen has real potential as an aviation fuel, he said, either directly for use in fuel cells for power or burned directly for propulsion, or indirectly as a feedstock for synthetic fuels. Both are being studied by the company, he said, including a hybrid model that uses both hydrogen fuel cells and hydrogen-fueled jet engines. The company projects a range of 2,000 nautical miles for a jet carrying 200 to 300 passengers, he said — all with no direct emissions and no contrails.

    But this vision will not be practical, Llewellyn said, unless economies of scale help to significantly lower the cost of hydrogen production. “Hydrogen is at the hub of aviation decarbonization,” he said. But that kind of price reduction seems quite feasible, he said, given that other major industries are also seriously looking at the use of hydrogen for their own decarbonization plans, including the production of steel and cement.

    Such uses were the subject of a panel discussion entitled “Deploying the Hydrogen Economy.” Hydrogen production technology exists, but not nearly at the scale that’s needed, which is about 500 million tons a year, pointed out moderator Dharik Mallapragada of the MIT Energy Initiative.

    Yet in some applications, the use of hydrogen both reduces emissions and is economically competitive. Preeti Pande of Plug Power said that her company, which produces hydrogen fuel cells, has found a significant market in an unexpected place: fork lifts, used in warehouses and factories worldwide. It turns out that replacing current battery-operated versions with fuel cell versions is a win-win for the companies that use them, saving money while helping to meet decarbonization goals.

    Lindsay Ashby of Avangrid Renewables said that the company has installed fuel-cell buses in Barcelona that run entirely on hydrogen generated by solar panels. The company is also building a 100-megawatt solar facility to produce hydrogen for the production of fertilizer, another major industry in need of decarbonization because of its large emissions footprint. And Brett Perleman of the Center for Houston’s Future said of his city that “we’re already a hydrogen hub today, just not green hydrogen” since the gas is currently mostly produced as a byproduct of fossil fuels. But that is changing rapidly, he said, and Houston, along with several other cities, aims to be a center of activity for hydrogen produced from renewable, non-carbon-emitting sources. They aim to be producing 1,000 tons a day by 2028, “and I think we’ll end up exceeding that,” he said.

    For industries that can switch to renewably generated electricity, that is typically the best choice, Perleman said. “But for those that can’t, hydrogen is a great option,” and that includes aviation, shipping, and rail. “The big oil companies all have plans in place” to develop clean hydrogen production, he said. “It’s not just a dream, but a reality.”

    For shipping, which tends to rely on bunker fuel, a particularly high-emissions fossil fuel, another potential option could be a new generation of small nuclear plants, said Jeff Navin of Terrapower, a company currently developing such units. “Finding replacements for coal, oil, or natural gas for industrial purposes is very hard,” he said, but often what these processes require is consistent high heat, which nuclear can deliver, as long as costs and regulatory issues can be resolved.  

    MIT professor of nuclear engineering Jacopo Buongiorno pointed out that the primary reasons for delays and cost overruns in nuclear plants have had to do with issues at the construction site, many of which could be alleviated by having smaller, factory-built modular plants, or by building multiple units at a time of a standardized design. If the government would take on the nuclear waste disposal, as some other countries have done, then nuclear power could play an important part in the decarbonization of many industries, he said.

    Student-led startups

    The two-day conference concluded with the final round of the annual MIT Climate and Energy Prize, consisting of the five finalist teams presenting brief pitches for their startup company ideas, followed by questions from the panel of judges. This year’s finalists included a team called Muket, dedicated to finding ways of reducing methane emissions from cattle and dairy farms. Feed additives or other measures could cut the emissions by 50 percent, the team estimates.

    A team called Ivu Biologics described a system for incorporating nitrogen-fixing microbes into the coatings of seeds, thereby reducing the need for added fertilizers, whose production is a major greenhouse gas source. The company is making use of seed-coating technology developed at MIT over the last few years. Another team, called Mesophase, also based on MIT-developed technology, aims to replace the condensers used in power plants and other industrial systems with much more efficient versions, thus increasing the energy output from a given amount of fuel or other heat source.

    A team called TerraTrade aims to facilitate the adoption of power purchase agreements by companies, institutions and governments, by acting as a kind of broker to create and administer such agreements, making it easier for even smaller entities to take part in these plans, which help to enable rapid development of renewable fossil-fuel-free energy production.

    The grand prize of $100,000 was awarded to a team called Ultropia, which is developing a combined clothes washer and drier that uses ultrasound instead of water for its cleaning. The system does use a small amount of water, but this can be recycled, making these usable even in areas where water availability is limited. The devices could have a great impact on the estimated 6 billion people in the world today who are still limited to washing clothes by hand, the team says, and because the machines would be so efficient, they would require very little energy to run — a significant improvement over the wider adoption of conventional washers and driers.

    Investors awaken to the risks of climate change

    Poppy Allonby, a senior financial executive and the former managing director of BlackRock, has been analyzing the link between climate change and investing for more than two decades. “For a lot of that, it was quite lonely,” Allonby said during her December address at the MIT Energy Initiative Fall Colloquium. “There weren’t that many other people looking at this field. And over the last three or four years, that’s completely changed.”

    Increasingly, Allonby said, investors are opening their eyes to the long-term risks of climate change — risks that threaten not only the planet, but also their portfolios. And as more institutional investors come to see climate change as a threat to their beneficiaries, they are taking action to fight it. Still, she cautioned that much more work remains to be done.

    “Various investors are at very different stages in considering climate change,” Allonby said. “Once they realize this is something they need to think about … they need to do a risk assessment, then develop a strategy.” 

    “When you look at different institutions,” she said, “some are just at the very beginning of this journey.”

    A changing landscape

    Although there is a compelling moral case to be made for taking steps to mitigate climate change, Allonby noted that institutional investors such as pension funds are bound by a fiduciary duty to their beneficiaries. That is to say, they are obligated to put their client or member interests ahead of their own.

    “I talk about fiduciary duty, because one of the things that has really changed in the investment space is that more and more investors are beginning to see climate change and climate risk as [impacting] their fiduciary duty,” said Allonby. “That has been a shift. In my mind, it makes total sense. If you’re a long-term investor … and you’re thinking about beneficiaries that need assets over the next 10 or 20 years, and thinking about risks that might materialize — and climate change, in particular — then that makes a lot of sense. But that is not where we were five or 10 years ago.”

    Allonby spent more than 20 years at the multinational investment management corporation BlackRock. For 17 of those years, she was a senior portfolio manager responsible for managing multibillion-dollar funds investing globally in companies across the traditional energy sector, and also those involved in sustainable energy and mitigating climate change. Most recently, she was head of the corporation’s Global Product Group on several continents, where she provided oversight for nearly $1 trillion assets and played a critical role in developing BlackRock’s sustainable product strategy.

    “Where I like to think the finance industry is heading is integration,” she said. “This means thinking holistically about pretty much every decision you make as an investor, and thinking about how climate risk is going to impact that investment. That is a sea change in the mentality around how people invest.”

    Divestment versus engagement

    For many years, activists have pushed for institutions — including MIT — to divest from fossil fuel companies. By keeping fossil fuel companies out of their portfolios, these activists argue, institutions and individuals can exert social, political, and economic pressure on these corporations and help to accelerate the shift to renewable energy.

    However, Allonby argued instead for ongoing engagement with fossil fuel companies, reasoning that this better positions investors to push for change. “My personal view with divesting from oil and gas companies is, that’s not very effective,” Allonby said. “I think there might be examples where you have very specific companies which you don’t think will be involved in the transition [to net zero], and [divestment] might make sense. Or if you’ve got an institutional investor where it is imperative that their investment is entirely aligned with their values — so, certain charities — it might make sense. But if you really care about change, I think you need to keep a seat at the table.”

    In a way, Allonby said, divesting from fossil fuel companies lets leaders at those organizations off the hook, reducing the pressure on them to make meaningful changes to their operations. “Imagine a company that is incredibly polluting and not sustainable, and they have shareholders that are not happy, but they don’t do anything, and those shareholders decide to divest,” she said. “What happens as a result of that, potentially, is the company goes, ‘Oh, that was easy! I didn’t have to do anything, and [the activists] have gone away.’ And potentially, those assets end up being owned by people who care less. So that is a risk, when you think about divestment.”

    Challenges and opportunities         

    Allonby outlined several challenges with climate-focused investing, but also noted a number of opportunities — both for investors looking to make money, and those looking to make a change.

    Among the challenges: For one, some investors simply still need to be convinced that climate change is a problem they should be working to solve. Also, Allonby said, there is a lack both of a formalized methodology and of specialized investment products for climate-focused investing, although she noted that both of these areas are improving. Finally, she said, it remains a challenge to encourage investors to direct capital toward clean-energy projects in developing countries. 

    Investors can both set themselves up for financial success and mitigate climate change, Allonby said, through savvy investments in either distressed or underpriced assets. “If you can buy assets that are discounted or cheaper because people have real concerns about their environmental footprint, then you can work with those companies to improve it and therefore reduce the risk and improve the valuation,” she said.

    Allonby, pointing to the high cost of waterfront property in areas that are vulnerable to rising sea levels, also suggested that the long-term risks of climate change have not been fully priced into many assets. “My view is that we haven’t really gotten our arms around that,” she said. “From a purely investment perspective, that’s also an opportunity.”

    Additionally, Allonby noted the recent rise of ESG funds, which invest with environmental, social, and corporate governance guidelines in mind. Some of these funds, she noted, have outperformed the larger market over the past several years.

    “When we talk about climate change, one has a range of emotions,” Allonby said. “Sometimes it can feel like we’re not making enough progress. And one of the nice things about being here at MIT is that whenever I’m here, I always feel hopeful about the future, and quite hopeful about all of the technologies and work that you are doing to transition energy systems and move things forward. When you look at what’s happening in the financial services sector, there’s still a huge amount to do, but it’s also quite a hopeful story.” More

    New visions for better transportation

    We typically experience transportation problems from the ground up. Waiting for a delayed bus, packing ourselves into a subway car, or crawling along in traffic, it is common to see such systems struggling at close range.

    Yet sometimes transportation solutions come from a high-level, top-down approach. That was the theme of the final talk in MIT’s Mobility Forum series, delivered on Friday by MIT Professor Thomas Magnanti, which centered on applying to transportation the same overarching analytical framework used in other domains, such as bioengineering.

    Magnanti’s remarks focused on a structured approach to problem-solving known as the 4M method — which stands for measuring, mining, modeling, and manipulating. In urban transportation planning, for instance, measuring and mining might involve understanding traffic flows. Modeling might simulate those traffic flows, and manipulating would mean engineering interventions: tolls, one-way streets, or other changes.

    “These are four things that interact quite a bit with each other,” said Magnanti, who is an Institute Professor — MIT’s highest faculty distinction — and a professor of operations research at the MIT Sloan School of Management. “And they provide us with a sense of how you can gather data and understand a system, but also how you can improve it.”

    Magnanti, a leading expert in operations research, pointed out that the 4M method can be applied to systems from physics to biomedical research. He outlined how it might be used to analyze transportations-related systems such as supply chains and warehouse movements.

    In all cases, he noted, applying the 4M concept to a system is an iterative process: Making changes to a system will likely produce new flows — of traffic and goods — and thus be subject to a new set of measurements.

    “One thing to notice here, once you manipulate the system, it changes the data,” Magnanti observed. “You’re doing this so you can hopefully improve operations, but it creates new data. So, you want to measure that new data again, you want to mine it, you want to model it again, and then manipulate it. … This is a continuing loop that we use in these systems.”

    Magnanti’s talk, “Understanding and Improving Transportation Systems,” was delivered online to a public audience of about 175 people. It was the 12th and final event of the MIT Mobility Forum in the fall 2021 semester. The event series is organized by the MIT Mobility Initiative, an Institute-wide effort to research and accelerate the evolution of transportation, at a time when decarbonization in the sector is critical.

    Other MIT Mobility Forum talks have focused on topics such as zero-environmental-impact aviation, measuring pedestrian flows in cities, autonomous vehicles, the impact of high-speed rail and subways on cities, values and equity in mobility design, and more.

    Overall, the forum “offers an opportunity to showcase the groundbreaking transportation research occurring across the Institute,” says Jinhua Zhao, an associate professor of transportation and city planning in MIT’s Department of Urban Studies and Planning, and director of the MIT Mobility Initiative.

    The initiative has held 39 such talks since it launched in 2020, and the series will continue again in the spring semester of 2022.

    One of the principal features of the forum, like the MIT Mobility Initiative in general, is that it “facilitates cross-disciplinary exchanges both within MIT and without,” Zhao says. Faculty and students from every school at MIT have participated in the forum, lending intellectual and methodological diversity to a broad field.

    For his part, Magnanti, who is both an engineer and operations researcher by training, embraced that interdisciplinary approach in his remarks, fielding a variety of audience questions after his talk, about research methods and other issues. Magnanti, who served from 2009 to 2017 as the founding president of the Singapore University of Technology and Design (with which MIT has had research collaborations), noted that the setting can heavily influence transportation research and progress.

    In Singapore, he noted, “They measure everything. They measure how people access the subway … and they use their data.” Of course, Singapore’s status as a city-state of modest size, among other factors, makes comprehensive transportation planning more feasible there. Still, Magnanti also noted that the infrastructure bill recently passed by the U.S. federal government is “going to provide lots of opportunities” for transportation improvements.

    And in general, Magnanti added, one of the best things academic leaders and research communities can do is to “continue to create a sense of excitement. Even when things are tough, the problems are going to be interesting.” More
