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.
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.
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.
Researchers at MIT have built a highly efficient thermophotovoltaic cell that converts incoming photons to electricity, reports Kevin Hurler for Gizmodo. “We developed this technology—thermal batteries—because storing energy as heat rather than storing it electrochemically is 10 to 100 times cheaper," explains Prof. Asegun Henry.
A team of researchers from MIT and the National Renewable Energy Laboratory successfully reached a 30% jump in thermophotovoltaic (TPV) efficiency, reports Robert F. Service for Science. “[TPV] is a semiconductor structure that concerts photons emitted from a heat source to electricity, just as a solar cell transforms sunlight into power,” explains Service.
Boston Globe reporter Hiawatha Bray spotlights how a number of MIT spinoffs are working on changing the world’s energy-storage systems. “Behind these companies are key technological advances in chemistry and materials, many of them pioneered at the Massachusetts Institute of Technology,” writes Bray. “These breakthroughs have put battery startups at the forefront of the region’s climate-tech sector.”
Senior research engineer Howard Herzog speaks with Bloomberg about the challenges facing the carbon capture industry and how we can get to net-zero emissions.
Washington Post columnist David Von Drehle spotlights MIT startup Form Energy, which has created a battery prototype made of iron and oxygen that stores large amounts of power and can release it over days. Von Drehle writes that this new battery could usher in a “sort of tipping point for green energy: reliable power from renewable sources at less than $20 per kilowatt-hour.”
MIT researchers have analyzed the role of long-duration energy storage technologies and found that large storage systems have the potential to lower electricity prices in a carbon-free grid by up to 40%, writes Eric Roston for Bloomberg.
“What we need to do, especially as we move more towards intermittent energy that we can’t predict as well as the output of thermal power plants is to keep adding to that resiliency,” says Robert Stoner, deputy director of the MIT Energy Initiative. Stoner discussed the recent failures of Texas’ power grid and what New England can learn from these events on WBUR’s Radio Boston.
Popular Mechanics reporter Kyro Mitchell spotlights how MIT researchers have created a new material, inspired by camel fur, that could be used to help insulate food and medical supplies. “Field tests on the new material show that it can provide cooling of more than seven degrees Celsius,” writes Mitchell. “It can also maintain that low temperature for five times longer than using hydrogel alone.”
Smithsonian reporter Corryn Wetzel spotlights how MIT researchers have developed a new technology inspired by camel fur that could be used to keep food and medical supplies chilled. The researchers hope the new system could be applied to “lots of areas that require passive cooling—meaning no external energy needs to power the process. Possible applications include insulating food storage, medical supplies and buildings.”
MIT researchers have created a new material that mimics camel fur and could be used to help keep food and medical supplies cool without electricity, reports Layal Liverpool for New Scientist. “We achieve evaporation and insulation at the same time, extending the cooling period significantly,” explains Prof. Jeffrey Grossman.
XiaoZhi Lim at The New York Times reports on a new study co-authored by researchers at MIT, which found that “by using a new class of electrolytes composed of ionic liquids, or salts that remain liquid at room temperature,” it may be possible for a supercapacitor to store as much energy as a lithium-ion battery.
