Renewable energy

Prof. Donald Sadoway and his colleagues have developed a battery that can charge to full capacity in less than one minute, store energy at similar densities to lithium-ion batteries and isn’t prone to catching on fire, reports Alex Wilkins for New Scientist. “Although the battery operates at the comparatively high temperature of 110°C (230°F),” writes Wilkins, “it is resistant to fire because it uses an inorganic salt that can’t burn as its electrolyte, the material that allows charge to flow inside a battery.” Sadoway explains that “this is a totally new battery chemistry."

MIT scientists have discovered a new method to maximize wind farm output, reports Gwen Egan for Boston.com. “While there are pros and cons to this strategy, it’s possible that it could allow for smaller wind farms that take up less land to produce more energy,” says Prof. Michael Howland. “It’s critically important we do this now, as we embark on building much more offshore wind. We need to ensure that our future wind farms maximize efficiency to increase the pace of decarbonization.”

MIT scientists have found that changing the angle of turbine blades on wind farms could increase energy output, reports David Abel for The Boston Globe. “Given the scale of wind deployment needed to achieve state and federal climate goals, we need optimal wind farm performance to ensure efficient, rapid decarbonization,” says Prof. Michael Howland. “Our method resulted in significant energy gains over standard industry operations, and, importantly, it can be instituted with minimal cost.”

Los Angeles Times reporter Sammy Roth spotlights Prof. Lawrence Susskind’s study that finds common sources of opposition to delayed or blocked renewable energy projects include concerns over land use and environmental impact. Roth writes that Susskind’s “research has convinced him that speeding up the clean energy transition will be possible only if developers take the time to make a good-faith effort to gather input from communities before dumping solar and wind farms on them.”

Quaise Energy co-founder Carlos Araque BS ’01 MS ’02 speaks with Guy Raz, host of NPR’s How I Built This, about his time on the MIT Electric Vehicle Team, starting his company and the future of geothermal energy. “We would build these cars together, literally from scratch,“ said Araque about the EVT. "Very hands on, a lot of engineering went into that. And it [offered] very early experience with building things that work -- not only work, but work reliantly and consistently.”  

Commonwealth Fusion Systems (CFS), an MIT spinout, has signed an agreement with the U.K. Atomic Energy Authority (UKAEA) to “support the fastest path to clean commercial fusion energy,” reports Ed Browne for Newsweek. “CFS says its agreement with UKAEA could involve exchanges of knowledge and collaboration on things like fuel, modeling, manufacturing and maintenance,” writes Browne. 

Ross Trethewey, co-host of This Old House, visits Prof. Vladimir Bulović, director of MIT.nano, to learn more about the future of solar technology, including an electricity-generating film that can be applied to windows and other materials. “Dramatic advancements are on the horizon,” says Bulović. “We can make solar cells that don’t weigh very much at all so deployment of them on top of your roof could be as simple as unrolling a carpet and stapling it to the roof with a plug. Maybe your windows will be turned into solar cells.” 

TechCrunch reporter Devin Coldewey writes that a new report by MIT researchers finds that in order to successfully transition to a renewable energy grid, the federal government must intervene to help build green energy storage at a scale that will meet the nation’s needs. “The federal government has the means both to subsidize the utilization of existing storage options and to fund intensive research into new and promising ones,” writes Coldewey of the report’s findings. 

Ambri, an MIT startup that has developed a liquid-metal battery that can be used for grid-level storage of renewable energy, has announced that it is months away from delivering its first battery to a customer, reports Jacob Wycoff for CBS Boston. "We want to have a battery that can draw from the sun even when the sun doesn't shine," said Prof. Donald Sadoway of the inspiration for Ambri’s battery.

Siblings Gia Schneider ‘99 and Abe Schneider SM ‘03 co-founded Natel, a company dedicated to developing sustainable, climate-resilient hydropower, reports Amy Gunia for TIME. “The siblings hope that what they’re doing can help demonstrate a more sustainable approach to renewable energy – proving that companies shouldn’t have to choose between what’s good for the environment and what works economically,” writes Gunia.

Prof. Donald Sadoway is the recipient of the 2022 European Inventor Award for his work in liquid metal batteries, reports WBUR. “MIT says the battery could enable the long-term storage of renewable energy,” says WBUR.

Researchers from MIT’s Plasma Science and Fusion Center (PSFC) and Commonwealth Fusion Systems (CFS) are working on making commercial nuclear fusion a reality, reports Juandre for Popular Mechanics. “CFS will build [the tokamak] SPARC and develop a commercial fusion product, while MIT PSFC will focus on its core mission of cutting-edge research and education,” says Prof. Dennis G. Whyte, director of the PSFC. 

Associate Provost Richard Lester and Prof. Noelle Selin speak with Tiziana Dearing, host of Radio Boston, about MIT’s Climate Grand Challenges. “To me, the Climate Grand Challenges effort really represents that we’re kind of at a frameshift when thinking about the climate problem. It’s not just a problem that some people can work on,” says Selin. “A climate challenge is a whole of society challenge, and therefore it really has to be a whole of MIT challenge.” Lester adds he hopes the challenges will “inspire a new generation of students to roll up their sleeves, put their shoulders to the wheel and help us solve this problem.”

WBUR reporter Bruce Gellerman spotlights a new report by MIT Energy Initiative (MITEI) researchers that emphasizes the importance of developing and deploying new ways to store renewable energy in order to transition to clean energy. “There are a variety of technologies and if we can develop [them] and drive those costs down, it could make getting to net-zero or zero in the electricity sector more affordable,” says Prof. Robert Armstrong, MITEI director.

A new report by researchers from MIT’s Energy Initiative (MITEI) underscores the feasibility of using energy storage systems to almost completely eliminate the need for fossil fuels to operate regional power grids, reports David Abel for The Boston Globe. “Our study finds that energy storage can help [renewable energy]-dominated electricity systems balance electricity supply and demand while maintaining reliability in a cost-effective manner,” says Prof. Robert Armstrong, director of MITEI.
