      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.

      MIT student club Engineers Without Borders works with local village in Tanzania

      by

      Four students from the MIT club Engineers Without Borders (EWB) spent part of their summer in Tanzania to begin assessment work for a health and sanitation project that will benefit the entire village, and an irrigated garden for the Mkutani Primary School.

      The club has been working with the Boston Professional Chapter of Engineers Without Borders (EWB-BPC) since 2019. The Boston chapter finds projects in underserved communities in the developing world and helped connect the MIT students with local government and school officials.

      Juniors Fiona Duong, female health and sanitation team lead, and Lai Wa Chu, irrigation team lead, spent two weeks over the summer in Mkutani conducting research for their projects. Chu was faced with finding more water supplies and a way to get water from the nearby river to the school to use in the gardens they were planting. Duong was charged with assessing the needs of the people who visit The Mkutani Dispensary, which serves as a local medical clinic. Juniors Hung Huynh, club president, and Vivian Cheng, student advisor, also made the trip to work on the projects.

      Health and sanitation project

      Duong looked into ways to help pregnant women with privacy issues as the facility they give birth in — The Mkutani Dispensary — is very small, with just two beds, and is in need of repairs and upgrades. Before leaving Cambridge, Duong led FaceTime meetings with government officials and facilities managers in the village. Once on the ground, she began collecting information and conducted focus groups with the local women and other constituents. She learned that one in three women were not giving birth in the dispensary due to privacy concerns and the lack of modern equipment needed for high-risk pregnancies.

      “The women said that the most pressing need there was water. The women were expected to bring their own water to their deliveries. The rain-catching system there was not enough to fulfill their needs and the river water wasn’t clean. When in labor, they relied on others to gather it and bring it to the dispensary by bike,” Duong says. “With broken windows, the dispensary did not allow for privacy or sanitary conditions.”

      Duong will also analyze the data she collected and share it with others before more MIT students head to Mkutani next summer.

      Farming, sustainability, and irrigation projectBefore heading to Mkutani, Chu conducted research regarding irrigation methods and water collection methods. She confirmed that the river water still contained E.coli and advised the teachers that it would need to be boiled or placed in the sun for a few hours before it could be used. Her technical background in fluid dynamics was helpful for the project.

      “We also found that there was a need for supplemental food for the school, as many children lived too far away to walk home for lunch. The headmaster reached out to us about building the garden, as the garden provides supplemental fruit and vegetables for many of the 600 students to eat. They needed water from the river that was quite far away from the school. We looked at ways to get the water to the garden,” Chu says.

      The group is considering conducting an ecological survey of the area to see if there is another source of water so they could drill another borehole. They will complete their analysis and then decide the best solution to implement.

      “Watching the whole team’s hard work pay off when the travel team got to Mkutani was so amazing,” says second-year student Maria Hernandez, club internal relations chair. “Now, we’re ready to get to work again so we can go back next year. I love being a part of Engineers Without Borders because it’s such a unique way to apply technical skills outside of the classroom and see the impact you make on the community. It’s a beautiful project that truly impacts so many people, and I can’t wait to go back to Mkutani next year.”

      Both Duong and Chu hope they’ll return to the school and the dispensary in summer 2023 to work on the implementation phase of their projects. “This project is one of the reasons I came to MIT. I wanted to work on a social impact project to help improve the world,” Chu says.

      “I hope to go back next summer and implement the project,” adds Duong. “If I do, we’ll go during the two most crucial weeks of the project — after the contractors have started the repair work on the dispensary, so we can see how things are going and then help with anything else related to the project.”

      Duong and Chu said students don’t have to be engineers to help with the EWB’s work — any MIT student interested in joining the club may do so. Both agree that fundraising is a priority, but there are numerous other roles students can help with.

      “MIT students shouldn’t be afraid to just dive right in. There’s a lot that needs to be done there, and even if you don’t have experience in a certain area, don’t let that be a barrier. It’s very rewarding work and it’s also great to get international work experience,” Duong says.

      Chu added, “The project may not seem flashy now, but the rewards are great. Students will get new technical skills and get to experience a new culture as well.” More

      MIT accelerates efforts on path to carbon reduction goals

      by

      Under its “Fast Forward” climate action plan, which was announced in May 2021, MIT has set a goal of eliminating direct emissions from its campus by 2050. An important near-term milestone will be achieving net-zero emissions by 2026. Many other colleges and universities have set similar targets. What does it take to achieve such a dramatic reduction?

      Since 2014, when MIT launched a five-year plan for action on climate change, net campus emissions have been cut by 20 percent. To meet the 2026 target, and ultimately achieve zero direct emissions by 2050, the Institute is making its campus buildings dramatically more energy efficient, transitioning to electric vehicles (EVs), and enabling large-scale renewable energy projects, among other strategies.

      “This is an ‘all-in’ moment for MIT, and we’re taking comprehensive steps to address our carbon footprint,” says Glen Shor, executive vice president and treasurer. “Reducing our emissions to zero will be challenging, but it’s the right aspiration.”

      “As an energy-intensive campus in an urban setting, our ability to achieve this goal will, in part, depend on the capacity of the local power grid to support the electrification of buildings and transportation, and how ‘green’ that grid electricity will become over time,” says Joe Higgins, MIT’s vice president for campus services and stewardship. “It will also require breakthrough technology improvements and new public policies to drive their adoption. Many of those tech breakthroughs are being developed by our own faculty, and our teams are planning scenarios in anticipation of their arrival.”

      Working toward an energy-efficient campus

      The on-campus reductions have come primarily from a major upgrade to MIT’s Central Utilities Plant, which provides electricity, heating, and cooling for about 80 percent of all Institute buildings. The upgraded plant, which uses advanced cogeneration technology, became fully operational at the end of 2021 and is meeting campus energy needs at greater efficiency and lower carbon intensity (on average 15 to 25 percent cleaner) compared to the regional electricity grid. Carbon reductions from the increased efficiency provided by the enhanced plant are projected to counter the added greenhouse gas emissions caused by recently completed and planned construction and operation of new buildings on campus, especially energy-intensive laboratory buildings.

      Energy from the plant is delivered to campus buildings through MIT’s district energy system, a network of underground pipes and power lines providing electricity, heating, and air conditioning. With this adaptable system, MIT can introduce new technologies as they become available to increase the system’s energy efficiency. The system enables MIT to export power when the regional grid is under stress and to import electricity from the power grid as it becomes cleaner, likely over the next decade as the availability of offshore wind and renewable resources increases. “At the same time, we are reviewing additional technology options such as industrial-scale heat pumps, thermal batteries, geothermal exchange, microreactors, bio-based fuels, and green hydrogen produced from renewable energy,” Higgins says.

      Along with upgrades to the plant, MIT is gradually converting existing steam-based heating systems into more efficient hot-water systems. This long-term project to lower campus emissions requires replacing the vast network of existing steam pipes and infrastructure, and will be phased in as systems need to be replaced. Currently MIT has four buildings that are on a hot-water system, with five more buildings transitioning to hot water by the fall of 2022.  

      Minimizing emissions by implementing meaningful building efficiency standards has been an ongoing strategy in MIT’s climate mitigation efforts. In 2016, MIT made a commitment that all new campus construction and major renovation projects must earn at least Leadership in Energy and Environmental Design (LEED) Gold certification. To date, 24 spaces and buildings at MIT have earned a LEED designation, a performance-based rating system of a building’s environmental attributes associated with its design, construction, operations, and management.

      Current efficiency efforts focus on reducing energy in the 20 buildings that account for more than 50 percent of MIT’s energy usage. One such project under construction aims to improve energy efficiency in Building 46, which houses the Department of Brain and Cognitive Sciences and the Picower Institute for Learning and Memory and is the biggest energy user on the campus because of its large size and high concentration of lab spaces. Interventions include optimizing ventilation systems that will significantly reduce energy use while improving occupant comfort, and working with labs to implement programs such as fume hood hibernation and equipment adjustments. For example, raising ultralow freezer set points by 10 degrees can reduce their energy consumption by as much as 40 percent. Together, these measures are projected to yield a 35 percent reduction in emissions for Building 46, which would contribute to reducing campus-level emissions by 2 percent.

      Over the past decade, in addition to whole building intervention programs, the campus has taken targeted measures in over 100 campus buildings to add building insulation, replace old, inefficient windows, transition to energy-efficient lighting and mechanical systems, optimize lab ventilation systems, and install solar panels on solar-ready rooftops on campus — and will increase the capacity of renewable energy installations on campus by a minimum of 400 percent by 2026. These smaller scale contributions to overall emissions reductions are essential steps in a comprehensive campus effort.

      Electrification of buildings and vehicles

      With an eye to designing for “the next energy era,” says Higgins, MIT is looking to large-scale electrification of its buildings and district energy systems to reduce building use-associated emissions. Currently under renovation, the Metropolitan Storage Warehouse — which will house the MIT School of Architecture and Planning (SA+P) and the newly established MIT Morningside Academy for Design — will be the first building on campus to undergo this transformation by using electric heat pumps as its main heating and supplemental cooling source. The project team, consisting of campus engineering and construction teams as well as the designers, is working with SA+P faculty to design this innovative electrification project. The solution will move excess heat from the district energy infrastructure and nearby facilities to supply the heat pump system, creating a solution that uses less energy — resulting in fewer carbon emissions. 

      Next to building energy use, emissions from on-campus vehicles are a key target for reduction; one of the goals in the “Fast Forward” plan is the electrification of on-campus vehicles. This includes the expansion of electric vehicle charging stations, and work has begun on the promised 200 percent expansion of the number of stations on campus, from 120 to 360. Sites are being evaluated to make sure that all members of the MIT community have easy access to these facilities.

      The electrification also includes working toward replacing existing MIT-owned vehicles, from shuttle buses and vans to pickup trucks and passenger cars, as well as grounds maintenance equipment. Shu Yang Zhang, a junior in the Department of Materials Science and Engineering, is part of an Office of Sustainability student research team that carried out an evaluation of the options available for each type of vehicle and compared both their lifecycle costs and emissions.

      Zhang says the team examined “the specifics of the vehicles that we own, looking at key measures such as fuel economy and cargo capacity,” and determined what alternatives exist in each category. The team carried out a study of the costs for replacing existing vehicles with EVs on the market now, versus buying new gas vehicles or leaving the existing ones in place. They produced a set of specific recommendations about fleet vehicle replacement and charging infrastructure installation on campus that supports both commuters and an MIT EV fleet in the future. According to their estimates, Zhang says, “the costs should be not drastically different” in the long run for the new electric vehicles.

      Strength in numbers

      While a panoply of measures has contributed to the successful offsetting of emissions so far, the biggest single contributor was MIT’s creation of an innovative, collaborative power purchase agreement (PPA) that enabled the construction of a large solar farm in North Carolina, which in turn contributed to the early retirement of a large coal-fired power plant in that region. MIT is committed to buying 73 percent of the power generated by the new facility, which is equivalent to approximately 40 percent of the Institute’s electricity use.

      That PPA, which was a collaboration between three institutions, provided a template that has already been emulated by other institutions, in many cases enabling smaller organizations to take part in such a plan and achieve greater offsets of their carbon emissions than might have been possible acting on their own. Now, MIT is actively pursuing new, larger variations on that plan, which may include a wider variety of organizational participants, perhaps including local governments as well as institutions and nonprofits. The hope is that, as was the case with the original PPA, such collaborations could provide a model that other institutions and organizations may adopt as well.

      Strategic portfolio agreements like the PPA will help achieve net zero emissions on campus while accelerating the decarbonization of regional electricity grids — a transformation critical to achieving net zero emissions, alongside all the work that continues to reduce the direct emissions from the campus itself.

      “PPAs play an important role in MIT’s net zero strategy and have an immediate and significant impact in decarbonization of regional power grids by enabling renewable energy projects,” says Paul L. Joskow, the Elizabeth and James Killian Professor of Economics. “Many well-known U.S. companies and organizations that are seeking to enable and purchase CO2-free electricity have turned to long-term PPAs selected through a competitive procurement process to help to meet their voluntary internal decarbonization commitments. While there are still challenges regarding organizational procurements — including proper carbon emissions mitigation accounting, optimal contract design, and efficient integration into wholesale electricity markets — we are optimistic that MIT’s efforts and partnerships will contribute to resolving some of these issues.”

      Addressing indirect sources of emissions

      MIT’s examination of emissions is not limited to the campus itself but also the indirect sources associated with the Institute’s operations, research, and education. Of these indirect emissions, the three major ones are business travel, purchased goods and services, and construction of buildings, which are collectively larger than the total direct emissions from campus.

      The strategic sourcing team in the Office of the Vice President for Finance has been working to develop opportunities and guidelines for making it easier to purchase sustainable products, for everything from office paper to electronics to lab equipment. Jeremy Gregory, executive director of MIT’s Climate and Sustainability Consortium, notes that MIT’s characteristic independent spirit resists placing limits on what products researchers can buy, but, he says, “we have opportunities to centralize some of our efforts and empower our community to choose low-impact alternatives when making procurement decisions.”

      The path forward

      The process of identifying and implementing MIT’s carbon reductions will be supported, in part, by the Carbon Footprint Working Group, which was launched by the Climate Nucleus, a new body MIT created to manage the implementation of the “Fast Forward” climate plan. The nucleus includes a broad representation from MIT’s departments, labs, and centers that are working on climate change issues. “We’ve created this internal structure in an effort to integrate operational expertise with faculty and student research innovations,” says Director of Sustainability Julie Newman.

      Whatever measures end up being adopted to reduce energy and associated emissions, their results will be made available continuously to members of the MIT community in real-time, through a campus data gateway, Newman says — a degree of transparency that is exceptional in higher education. “If you’re interested in supporting all these efforts and following this,” she says, “you can track the progress via Energize MIT,” a set of online visualizations that display various measures of MIT’s energy usage and greenhouse gas emissions over time.

      Promoting systemic change in the Middle East, the “MIT way”

      by

      The Middle East is a region that is facing complicated challenges. MIT programs have been committed to building scalable methodologies through which students and the broader MIT community can learn and make an impact. These processes ensure programs work alongside others across cultures to support change aligned with their needs. Through MIT International Science and Technology Initiatives (MISTI), faculty and staff at the Institute continue to build opportunities to connect with and support the region.

      In this spirit, MISTI launched the Leaders Journey Workshop in 2021. This program partnered MIT students with Palestinian and Israeli alumni from three associate organizations: Middle East Entrepreneurs for Tomorrow (MEET), Our Generation Speaks (OGS), and Tech2Peace. Teams met monthly to engage with speakers and work with one another to explore the best ways to leverage science, technology, and entrepreneurship across borders.

      Building on the success of this workshop, the program piloted a for-credit course: SP.258 (MISTI: Middle East Cross-Border Development and Leadership) in fall 2021. The course involved engaging with subject matter experts through five mini-consulting projects in collaboration with regional stakeholders. Topics included climate, health care, and economic development. The course was co-instructed by associate director of the MIT Regional Entrepreneurship Acceleration Program (REAP) Sinan AbuShanab, managing director of MISTI programs in the Middle East David Dolev, and Kathleen Schwind ’19, with MIT CIS/ MISTI Research Affiliate Steven Koltai as lead mentor. The course also drew support from alumni mentors and regional industry partners.

      The course was developed during the height of the pandemic and thus successfully leveraged the intense culture of online engagement prevalent at the time by layering in-person coursework with strategic digital group engagement. Pedagogically, the structure was inspired by multiple MIT methodologies: MISTI preparation and training courses, Sloan Action Learning, REAP/REAL multi-party stakeholder model, the Media Lab Learning Initiative, and the multicultural framework of associate organizations.

      “We worked to develop a series of aims and a methodology that would enrich MIT students and their peers in the region and support the important efforts of Israelis and Palestinians to make systemic change,” said Dolev.

      During the on-campus sessions, MIT students explored the region’s political and historical complexities and the meaning of being a global leader and entrepreneur. Guest presenters included: Boston College Associate Professor Peter Krause (MIT Security Studies Program alumnus), Gilad Rosenzweig (MITdesignX), Ari Jacobovits (MIT-Africa), and Mollie Laffin-Rose Agbiboa (MIT-REAP). Group projects focused on topics that fell under three key regional verticals: water, health care, and economic development. The teams were given a technical or business challenge they were tasked with solving. These challenges were sourced directly from for-profit and nonprofit organizations in the region.

      “This was a unique opportunity for me to learn so much about the area I live in, work on a project together with people from the ‘other side,’ MIT students, and incredible mentors,” shared a participant from the region. “Furthermore, getting a glimpse of the world of MIT was a great experience for me.”

      For their final presentations, teams pitched their solutions, including their methodology for researching/addressing the problem, a description of solutions to be applied, what is needed to execute the idea itself, and potential challenges encountered. Teams received feedback and continued to deepen their experience in cross-cultural teamwork.

      “As an education manager, I needed guidance with these digital tools and how to approach them,” says an EcoPeace representative. “The MIT program provided me with clear deliverables I can now implement in my team’s work.”

      “This course has broadened my knowledge of conflicts, relationships, and how geography plays an important role in the region,” says an MIT student participant. “Moving forward, I feel more confident working with business and organizations to develop solutions for problems in real time, using the skills I have to supplement the project work.”

      Layers of engagement with mentors, facilitators, and whole-team leadership ensured that participants gained project management experience, learning objectives were met, and professional development opportunities were available. Each team was assigned an MIT-MEET alumni mentor with whom they met throughout the course. Mentors coached the teams on methods for managing a client project and how to collaborate for successful completion. Joint sessions with MIT guest speakers deepened participants’ regional understanding of water, health care, economic development, and their importance in the region. Speakers included: Mohamed Aburawi, Phil Budden (MIT-REAP) Steven Koltai, Shari Loessberg, Dina Sherif (MIT Legatum Center, Greg Sixt (J-WAFS), and Shriya Srinivasan.

      “The program is unlike any other I’ve come across,” says one of the alumni mentors. “The chance for MIT students to work directly with peers from the region, to propose and create technical solutions to real problems on the ground, and partner with local organizations is an incredibly meaningful opportunity. I wish I had been able to participate in something like this when I was at MIT.”

      Each team also assigned a fellow group member as a facilitator, who served as the main point of contact for the team and oversaw project management: organizing workstreams, ensuring deadlines were met, and mediating any group disagreements. This model led to successful project outcomes and innovative suggestions.

      “The superb work of the MISTI group gave us a critical eye and made significant headway on a product that can hopefully be a game changer to over 150 Israeli and Palestinian organizations,” says a representative from Alliance for Middle East Peace (ALLMEP).

      Leadership team meetings included MIT staff and Israeli and Palestinian leadership of the partner organizations for discussing process, content, recent geopolitical developments, and how to adapt the class to the ongoing changing situation.

      “The topic of Palestine/Israel is contentious: globally, in the region, and also, at times, on the MIT campus,” says Dolev. “I myself have questioned how we can make a systemic impact with our partners from the region. How can we be side-by-side on that journey for the betterment of all? I have now seen first-hand how this multilayered model can work.”

      MIT International Science and Technology Initiatives (MISTI) is MIT’s hub for global experiences. MISTI’s unparalleled internship, research, teaching, and study abroad programs offer students unique experiences that bring MIT’s one-of-a-kind education model to life in countries around the world. MISTI programs are carefully designed to complement on-campus course work and research, and rigorous, country-specific preparation enables students to forge cultural connections and play a role in addressing important global challenges while abroad. Students come away from their experiences with invaluable perspectives that inform their education, career, and worldview. MISTI embodies MIT’s commitment to global engagement and prepares students to thrive in an increasingly interconnected world. More

      New J-WAFS-led project combats food insecurity

      by

      Today the Abdul Latif Jameel Water and Food Systems Lab (J-WAFS) at MIT announced a new research project, supported by Community Jameel, to tackle one of the most urgent crises facing the planet: food insecurity. Approximately 276 million people worldwide are severely food insecure, and more than half a million face famine conditions.     To better understand and analyze food security, this three-year research project will develop a comprehensive index assessing countries’ food security vulnerability, called the Jameel Index for Food Trade and Vulnerability. Global changes spurred by social and economic transitions, energy and environmental policy, regional geopolitics, conflict, and of course climate change, can impact food demand and supply. The Jameel Index will measure countries’ dependence on global food trade and imports and how these regional-scale threats might affect the ability to trade food goods across diverse geographic regions. A main outcome of the research will be a model to project global food demand, supply balance, and bilateral trade under different likely future scenarios, with a focus on climate change. The work will help guide policymakers over the next 25 years while the global population is expected to grow, and the climate crisis is predicted to worsen.    

      The work will be the foundational project for the J-WAFS-led Food and Climate Systems Transformation Alliance, or FACT Alliance. Formally launched at the COP26 climate conference last November, the FACT Alliance is a global network of 20 leading research institutions and stakeholder organizations that are driving research and innovation and informing better decision-making for healthy, resilient, equitable, and sustainable food systems in a rapidly changing climate. The initiative is co-directed by Greg Sixt, research manager for climate and food systems at J-WAFS, and Professor Kenneth Strzepek, climate, water, and food specialist at J-WAFS.

      The dire state of our food systems

      The need for this project is evidenced by the hundreds of millions of people around the globe currently experiencing food shortages. While several factors contribute to food insecurity, climate change is one of the most notable. Devastating extreme weather events are increasingly crippling crop and livestock production around the globe. From Southwest Asia to the Arabian Peninsula to the Horn of Africa, communities are migrating in search of food. In the United States, extreme heat and lack of rainfall in the Southwest have drastically lowered Lake Mead’s water levels, restricting water access and drying out farmlands. 

      Social, political, and economic issues also disrupt food systems. The effects of the Covid-19 pandemic, supply chain disruptions, and inflation continue to exacerbate food insecurity. Russia’s invasion of Ukraine is dramatically worsening the situation, disrupting agricultural exports from both Russia and Ukraine — two of the world’s largest producers of wheat, sunflower seed oil, and corn. Other countries like Lebanon, Sri Lanka, and Cuba are confronting food insecurity due to domestic financial crises.

      Few countries are immune to threats to food security from sudden disruptions in food production or trade. When an enormous container ship became lodged in the Suez Canal in March 2021, the vital international trade route was blocked for three months. The resulting delays in international shipping affected food supplies around the world. These situations demonstrate the importance of food trade in achieving food security: a disaster in one part of the world can drastically affect the availability of food in another. This puts into perspective just how interconnected the earth’s food systems are and how vulnerable they remain to external shocks. 

      An index to prepare for the future of food

      Despite the need for more secure food systems, significant knowledge gaps exist when it comes to understanding how different climate scenarios may affect both agricultural productivity and global food supply chains and security. The Global Trade Analysis Project database from Purdue University, and the current IMPACT modeling system from the International Food Policy Research Institute (IFPRI), enable assessments of existing conditions but cannot project or model changes in the future.

      In 2021, Strzepek and Sixt developed an initial Food Import Vulnerability Index (FIVI) as part of a regional assessment of the threat of climate change to food security in the Gulf Cooperation Council states and West Asia. FIVI is also limited in that it can only assess current trade conditions and climate change threats to food production. Additionally, FIVI is a national aggregate index and does not address issues of hunger, poverty, or equity that stem from regional variations within a country.

      “Current models are really good at showing global food trade flows, but we don’t have systems for looking at food trade between individual countries and how different food systems stressors such as climate change and conflict disrupt that trade,” says Greg Sixt of J-WAFS and the FACT Alliance. “This timely index will be a valuable tool for policymakers to understand the vulnerabilities to their food security from different shocks in the countries they import their food from. The project will also illustrate the stakeholder-guided, transdisciplinary approach that is central to the FACT Alliance,” Sixt adds.

      Phase 1 of the project will support a collaboration between four FACT Alliance members: MIT J-WAFS, Ethiopian Institute of Agricultural Research, IFPRI (which is also part of the CGIAR network), and the Martin School at the University of Oxford. An external partner, United Arab Emirates University, will also assist with the project work. This first phase will build on Strzepek and Sixt’s previous work on FIVI by developing a comprehensive Global Food System Modeling Framework that takes into consideration climate and global changes projected out to 2050, and assesses their impacts on domestic production, world market prices, and national balance of payments and bilateral trade. The framework will also utilize a mixed-modeling approach that includes the assessment of bilateral trade and macroeconomic data associated with varying agricultural productivity under the different climate and economic policy scenarios. In this way, consistent and harmonized projections of global food demand and supply balance, and bilateral trade under climate and global change can be achieved. 

      “Just like in the global response to Covid-19, using data and modeling are critical to understanding and tackling vulnerabilities in the global supply of food,” says George Richards, director of Community Jameel. “The Jameel Index for Food Trade and Vulnerability will help inform decision-making to manage shocks and long-term disruptions to food systems, with the aim of ensuring food security for all.”

      On a national level, the researchers will enrich the Jameel Index through country-level food security analyses of regions within countries and across various socioeconomic groups, allowing for a better understanding of specific impacts on key populations. The research will present vulnerability scores for a variety of food security metrics for 126 countries. Case studies of food security and food import vulnerability in Ethiopia and Sudan will help to refine the applicability of the Jameel Index with on-the-ground information. The case studies will use an IFPRI-developed tool called the Rural Investment and Policy Analysis model, which allows for analysis of urban and rural populations and different income groups. Local capacity building and stakeholder engagement will be critical to enable the use of the tools developed by this research for national-level planning in priority countries, and ultimately to inform policy.  Phase 2 of the project will build on phase 1 and the lessons learned from the Ethiopian and Sudanese case studies. It will entail a number of deeper, country-level analyses to assess the role of food imports on future hunger, poverty, and equity across various regional and socioeconomic groups within the modeled countries. This work will link the geospatial national models with the global analysis. A scholarly paper is expected to be submitted to show findings from this work, and a website will be launched so that interested stakeholders and organizations can learn more information. More

      Helping cassava farmers by extending crop life

      by

      The root vegetable cassava is a major food staple in dozens of countries across the world. Drought-resistant, nutritious, and tasty, it has also become a major source of income for small-scale, rural farmers in places like West Africa and Southeast Asia.

      But the utility of cassava has always been limited by its short postharvest shelf life of two to three days. That puts millions of farmers who rely on the crop in a difficult position. The farmers can’t plant more than they can sell quickly in local markets, and they’re often forced to sell below market prices because buyers know the harvest will spoil rapidly. As a result, cassava farmers are among the world’s poorest people.

      Now the startup CassVita is buying cassava directly from farmers and applying a patent-pending biotechnology to extend its shelf life to 18 months. The approach has the potential to transform economies in rural, impoverished regions where millions of families rely on the crop for income.

      CassVita tells farmers how much cassava the company will buy each month, and processes the cassava at a manufacturing facility in Cameroon. It currently sells the first version of its product as a powdered food to people in Cameroon and to West African immigrants in the U.S.

      But CassVita founder and CEO Pelkins Ajanoh ’18 says the future of the company will revolve around its next product: a cassava-based flour that can act as a direct substitute for wheat. The wheat substitute would dramatically broaden CassVita’s target market to include the fast-growing, trillion-dollar healthy food market.

      Ajanoh says CassVita is currently able to increase farmers’ incomes by about 400 percent through its purchases.

      “Our objective is to leverage proprietary technology to offer a healthier and better-tasting alternative to wheat while creating prosperity for local farmers,” Ajanoh says. “We’re hoping to tap into this huge market while empowering farmers, all by minimizing spoilage and incentivizing farmers to plant more.”

      Gaining confidence to help a community

      While growing up in Cameroon, Ajanoh’s parents always emphasized the importance of education for him and his three siblings. But Ajanoh lost his father when he was 13, and his mother moved to the U.S. a year later to help provide for the family. During that time, Ajanoh lived with his grandmother, a cassava farmer. For many years, Ajanoh watched his grandmother harvest cassava without making any lasting financial gains. He remembers feeling powerless as his grandmother struggled to pay for things like diabetes medication.

      Then Ajanoh earned the top marks on the national exams that Cameroonian students take before college. After high school, he joined his mother in the U.S. and came to MIT to study mechanical engineering. Once on campus, Ajanoh says he had lunch with new people all the time to learn from them.

      “I’d never had this community of intellectuals — and they were from all over the world — so I soaked up as much as I could,” Ajanoh says. “That sparked an interest in entrepreneurship, because MIT is super entrepreneurial. Everyone’s thinking of starting something cool.”

      Ajanoh also got a confidence boost during an internship in the summer after his junior year, when he created self-driving technology for General Motors that was eventually patented.

      “It made me realize I could do something really valuable for the world, and by the end of that internship I was thinking, ‘Now I want to solve a problem in my community,’” he says.

      Returning to the crop he knew well, Ajanoh received a series of grants from the MIT Sandbox Innovation Fund to experiment with ways to extend the shelf life of cassava. In the summer of 2018, the MIT-Africa program sponsored three MIT students to fly to Cameroon with him to participate in internships with the company.

      Today CassVita partners with development banks to help farmers get loans to buy the cassava sticks used for planting. Ajanoh says CassVita decided on a powdered food for its first product because it requires less marketing to sell to West Africans, who are familiar with the dish. Now the company is working on a cassava flour that it will market to all consumers looking for healthy alternatives to wheat that can be used in pastries and other baked goods.

      “Cassava makes sense as a global substitute to wheat because it’s gluten free, grain free, nut free, and it also helps with glucose regulation, to normalize blood sugar levels, to lower triglycerides, so the health benefits are exciting,” Ajanoh says. “But the farmers were still living in poverty, so if we could solve the shelf-life problem then we could empower these farmers to offer healthier wheat alternatives to the global market.”

      The project has taken on additional urgency now that the war in Ukraine is limiting that country’s wheat and grain exports, raising prices, and heightening food insecurity in regions around the globe.

      Showing the value of helping farmers

      Ajanoh says the majority of people farming cassava are women, and he says the challenges related to cassava’s shelf life have contributed to gender inequities in many communities. In fact, of the roughly 500 farmers CassVita works with in Cameroon, 95 percent are women.

      “That has always excited me because I was raised by women, so working on something that could empower women in their communities and give them authority is fulfilling,” Ajanoh says.

      Ajanoh has already heard from farmers who have been able to send their children to school for the first time because of improved financial situations. Now, as CassVita continues to scale, Ajanoh wants to stay focused on the technology that enables these new business models.

      “We’re evolving into a food technology company,” Ajanoh says. “We prefer to focus on leveraging technology to impact lives and improve outcomes in these communities. Right now, we’re going all the way to consumers because this is an opportunity the Nestles and the Unilevers of the world won’t pick up because the market doesn’t make sense to them yet. So, we have to build this company and show them the value.” More

      Helping renewable energy projects succeed in local communities

      by

      Jungwoo Chun makes surprising discoveries about sustainability initiatives by zooming in on local communities.

      His discoveries lie in understanding how renewable energy infrastructure develops at a local level. With so many stakeholders in a community — citizens, government officials, businesses, and other organizations — the development process gets complicated very quickly. Chun works to unpack stakeholder relationships to help local renewable energy projects move forward.

      While his interests today are in local communities around the U.S., Chun comes from a global background. Growing up, his family moved frequently due to his dad’s work. He lived in Seoul, South Korea until elementary school and then hopped from city to city around Asia, spending time in China, Hong Kong, and Singapore. When it was time for college, he returned to South Korea, majoring in international studies at Korea University and later completing his master’s there in the same field.

      After graduating, Chun wanted to leverage his international expertise to tackle climate change. So, he pursued a second master’s in international environmental policy with William Moomaw at Tufts University.

      During that time, Chun came across an article on climate change by David Victor, a professor in public policy at the University of California at San Diego. Victor argued that while international efforts to fight climate change are necessary, more tangible progress can be made through local efforts catered to each country. That prompted Chun to think a step further: “What can we do in the local community to make a little bit of a difference, which could add up to something big in the long term?”

      With a renewed direction for his goals, Chun arrived at the MIT Department of Urban Studies and Planning, specializing in environmental policy and planning. But he was still missing that final inspirational spark to proactively pursue his goals — until he began working with his primary advisor, Lawrence Susskind, the Ford Professor of Urban and Environmental Planning and director of the Science Impact Collaborative.

      For previous research projects, “I would just do what I was told,” Chun says, but his new advisor “really opened [his] eyes” to being an active member of the community. From the start, Susskind has encouraged Chun to share his research ideas and has shown him how to leverage his research skills for public service. Over the past few years, Chun has also taught several classes with Susskind, learning to approach education thoughtfully for an engaging and equitable classroom. Because of their relationship, Chun now always searches for ways to make a difference through research, teaching, and public service.

      Understanding renewable energy projects at a local level

      For his main dissertation project with Susskind, Chun is studying community-owned solar energy projects, working to understand what makes them successful.

      Often, communities don’t have the required expertise to carry out these projects on their own and instead look to advisory organizations for help. But little research has been done on these organizations and the roles that they play in developing solar energy infrastructure.

      Through over 200 surveys and counting, Chun has discovered that these organizations act as life-long collaborators to communities and are critical in getting community-owned solar projects up and running. At the start of these projects, they walk communities through a mountain of logistics for setting up solar energy infrastructure, including permit applications, budgeting, and contractor employment. After the infrastructure is in place, the organizations stay involved, serving as consultants when needed and sometimes even becoming partners.

      Because of these roles, Chun calls these organizations “intermediaries,” drawing a parallel with roles in in conflict resolution. “But it’s much more than that,” he adds. Intermediaries help local communities “build a movement [for community-owned solar energy projects] … and empower them to be independent and self-sustaining.”

      Chun is also working on another project with Susskind, looking at situations where communities are opposed to renewable energy infrastructure. For this project, Chun is supervising and mentoring a group of five undergraduates. Together, they are trying to pinpoint the reasons behind local opposition to renewable energy projects.

      The idea for this project emerged two years ago, when Chun heard in the news that many solar and wind projects were being delayed or cancelled due to local opposition. But the reasons for this opposition weren’t thoroughly researched.

      “When we started to dig a little deeper, [we found that] communities oppose these projects even though they aren’t opposed to renewable energy,” Chun says. The primary reasons for opposition lie in land use concerns, including financial challenges, health and safety concerns, and ironically, environmental consequences. By better understanding these concerns, Chun hopes to help more renewable energy projects succeed and bring society closer to a sustainable future.

      Bringing research to the classroom and community

      Right now, Chun is looking to bring his research insights on renewable energy infrastructure into the classroom. He’s developing a course on renewable energy that will act as a “clinic” where students will work with communities to understand their concerns for potential renewable energy projects. The students’ findings will then be passed onto project leaders to help them address these concerns.

      This new course is modeled after 11.074/11.274 (Cybersecurity Clinic), which Chun has helped develop over the past few years. In this clinic, students work with local governments in New England to assess potential cybersecurity vulnerabilities in their digital systems. At first, “a lot of city governments were very skeptical, like ‘students doing service for us…?’” Chun says. “But in the end, they were all very satisfied with the outcome” and found the assessments “impactful.”

      Since the Cybersecurity Clinic has kicked off, other universities have approached Chun and his co-instructors about developing their own regional clinics. Now, there are cybersecurity clinics operating around the world. “That’s been a huge success,” Chun says. Going forward, “we’d like to expand the benefit of this clinic [to address] communities opposing renewable energy [projects].” The new course will be a philosophical trifecta for Chun, combining his commitments to research, teaching, and public service.

      Chun plans to wrap up his PhD at the end of this summer and is currently writing his dissertation on community-owned solar energy projects. “I’m done with all the background work — working the soil and throwing the seeds in the right place,” he says, “It’s now time to gather all the crops and present the work.” More

      Study finds natural sources of air pollution exceed air quality guidelines in many regions

      by

      Alongside climate change, air pollution is one of the biggest environmental threats to human health. Tiny particles known as particulate matter or PM2.5 (named for their diameter of just 2.5 micrometers or less) are a particularly hazardous type of pollutant. These particles are produced from a variety of sources, including wildfires and the burning of fossil fuels, and can enter our bloodstream, travel deep into our lungs, and cause respiratory and cardiovascular damage. Exposure to particulate matter is responsible for millions of premature deaths globally every year.

      In response to the increasing body of evidence on the detrimental effects of PM2.5, the World Health Organization (WHO) recently updated its air quality guidelines, lowering its recommended annual PM2.5 exposure guideline by 50 percent, from 10 micrograms per meter cubed (μm3) to 5 μm3. These updated guidelines signify an aggressive attempt to promote the regulation and reduction of anthropogenic emissions in order to improve global air quality.

      A new study by researchers in the MIT Department of Civil and Environmental Engineering explores if the updated air quality guideline of 5 μm3 is realistically attainable across different regions of the world, particularly if anthropogenic emissions are aggressively reduced. 

      The first question the researchers wanted to investigate was to what degree moving to a no-fossil-fuel future would help different regions meet this new air quality guideline.

      “The answer we found is that eliminating fossil-fuel emissions would improve air quality around the world, but while this would help some regions come into compliance with the WHO guidelines, for many other regions high contributions from natural sources would impede their ability to meet that target,” says senior author Colette Heald, the Germeshausen Professor in the MIT departments of Civil and Environmental Engineering, and Earth, Atmospheric and Planetary Sciences. 

      The study by Heald, Professor Jesse Kroll, and graduate students Sidhant Pai and Therese Carter, published June 6 in the journal Environmental Science and Technology Letters, finds that over 90 percent of the global population is currently exposed to average annual concentrations that are higher than the recommended guideline. The authors go on to demonstrate that over 50 percent of the world’s population would still be exposed to PM2.5 concentrations that exceed the new air quality guidelines, even in the absence of all anthropogenic emissions.

      This is due to the large natural sources of particulate matter — dust, sea salt, and organics from vegetation — that still exist in the atmosphere when anthropogenic emissions are removed from the air. 

      “If you live in parts of India or northern Africa that are exposed to large amounts of fine dust, it can be challenging to reduce PM2.5 exposures below the new guideline,” says Sidhant Pai, co-lead author and graduate student. “This study challenges us to rethink the value of different emissions abatement controls across different regions and suggests the need for a new generation of air quality metrics that can enable targeted decision-making.”

      The researchers conducted a series of model simulations to explore the viability of achieving the updated PM2.5 guidelines worldwide under different emissions reduction scenarios, using 2019 as a representative baseline year. 

      Their model simulations used a suite of different anthropogenic sources that could be turned on and off to study the contribution of a particular source. For instance, the researchers conducted a simulation that turned off all human-based emissions in order to determine the amount of PM2.5 pollution that could be attributed to natural and fire sources. By analyzing the chemical composition of the PM2.5 aerosol in the atmosphere (e.g., dust, sulfate, and black carbon), the researchers were also able to get a more accurate understanding of the most important PM2.5 sources in a particular region. For example, elevated PM2.5 concentrations in the Amazon were shown to predominantly consist of carbon-containing aerosols from sources like deforestation fires. Conversely, nitrogen-containing aerosols were prominent in Northern Europe, with large contributions from vehicles and fertilizer usage. The two regions would thus require very different policies and methods to improve their air quality. 

      “Analyzing particulate pollution across individual chemical species allows for mitigation and adaptation decisions that are specific to the region, as opposed to a one-size-fits-all approach, which can be challenging to execute without an understanding of the underlying importance of different sources,” says Pai. 

      When the WHO air quality guidelines were last updated in 2005, they had a significant impact on environmental policies. Scientists could look at an area that was not in compliance and suggest high-level solutions to improve the region’s air quality. But as the guidelines have tightened, globally-applicable solutions to manage and improve air quality are no longer as evident. 

      “Another benefit of speciating is that some of the particles have different toxicity properties that are correlated to health outcomes,” says Therese Carter, co-lead author and graduate student. “It’s an important area of research that this work can help motivate. Being able to separate out that piece of the puzzle can provide epidemiologists with more insights on the different toxicity levels and the impact of specific particles on human health.”

      The authors view these new findings as an opportunity to expand and iterate on the current guidelines.  

      “Routine and global measurements of the chemical composition of PM2.5 would give policymakers information on what interventions would most effectively improve air quality in any given location,” says Jesse Kroll, a professor in the MIT departments of Civil and Environmental Engineering and Chemical Engineering. “But it would also provide us with new insights into how different chemical species in PM2.5 affect human health.”

      “I hope that as we learn more about the health impacts of these different particles, our work and that of the broader atmospheric chemistry community can help inform strategies to reduce the pollutants that are most harmful to human health,” adds Heald. More
