Prof. Kripa Varanasi and his colleagues have founded Alsym Energy, a startup working toward developing a lithium battery alternative, reports Hiawatha Bray for The Boston Globe. The founders say “they’ve built a new kind of rechargeable battery that delivers the performance of lithium ion cells at half the cost,” writes Bray.
Research Scientist David Correll speaks with Wall Street Journal reporter Cheryl Winokur Munk about the challenges companies are facing as they try to improve supply-chain sustainability. “Doing better at sustainability involves being closer and sharing information with some of your supply base,” says Correll. “There’s value to unlock through supplier development and collaboration in terms of innovation and resilience.”
Researchers at MIT have developed a silk-based biodegradable substitute for microplastics, reports Ysabelle Kempe for Scientific American. “This type of research is urgent for companies that face tightening regulations on deliberate use of microplastics,” writes Kempe.
Prof. Jessika Trancik speaks with Science Friday host Ira Flatow about the future of electric vehicles. “I think there is a lot happening in this space both coming from the private sector and then also from these government incentives coming in to accelerate that process,” says Trancik.
MIT and Delta airlines are developing a plan to eliminate persistent contrails, reports Susan Tran for NBC Boston 10. “A possible solution here is to get rid of these clouds flying at different altitudes,” says Tran. “They [researchers] say that up to 90 percent of all contrails could be avoided by flying at different heights.”
Researchers at MIT’s Department of Aeronautics and Astronautics and Delta Air Lines are working together to find new ways to eliminate persistent contrails, the white clouds that trail behind airplanes, using an algorithm that predicts altitudes and locations where contrails are likely to form, reports Omose Ighodaro for Bloomberg. “The joint research group has already completed more than 40 testing flights and has plans for live experiment flights and simulations,” writes Ighodaro.
MIT spinoff Gradiant, a water treatment facility developer, is working on new technology aimed at limiting the amount of water needed to produce lithium, reports Annie Lee and Janet Wu for Bloomberg. Gradiant’s process “can vastly improve lithium recovery and allow almost all wastewater to be recycled, has been developed in connection with Schlumberger’s NeoLith Energy venture,” writes Lee and Wu.
Prof. Kerry Emanuel discusses the impact climate change has on hurricanes, reports Robinson Meyer for The Atlantic. “First of all, you can have more intense hurricanes in a warmer climate. That finding goes back well over 30 years now,” says Emanuel. “For that reason we expect to see more of the highest-category storms—the Cat 3s, Cat 4s, Cat 5s, more of the Ian-style storms.”
Prof. Kerry Emanuel speaks with Newsweek reporter Pandora Dewan about Hurricane Ian and its correlation to climate change, reports Pandora Dewan for Newsweek. “What worries people in my profession is the confluence of two trends," says Emanuel. "One is demographic, one is nature. The number of people exposed to hurricanes has tripled since 1970 [as] people are moving in droves to hurricane-prone regions. Then the climate is changing, and that is demonstrably increasing the incidence of high-end storms like Ian."
Prof. Emeritus Donald Sadoway and his colleagues have developed a safer and more cost-effective battery to store renewable energy, reports David Abel for The Boston Globe. The battery is “ethically sourced, cheap, effective and can’t catch fire,” says Sadoway.
Researchers from MIT’s Research Laboratory for Electronics have developed a portable desalinator that can turn seawater into safe drinking water, reports Ian Mount for Fortune. Research scientist Jongyoon Han and graduate student Bruce Crawford have created Nona Technologies to commercialize the product, writes Mount.
Researchers from MIT and elsewhere have developed a new cost-effective battery design that relies on aluminum ion, reports Robert F. Service for Science. “The battery could be a blockbuster,” writes Service, “because aluminum is cheap; compared with lithium batteries, the cost of materials for these batteries would be 85% lower.”
Principal Research Scientist Randolph Kirchain, co-director of the Concrete Sustainability Hub, speaks with Jane Margolies of The New York Times about how the Inflation Reduction Act expands eligibility for tax credits for installing emissions-reduction equipment at manufacturing plants. “These credits are really valuable to keep technology coming down in cost,” says Kirchain.
David HC Correll, a research scientist at the MIT Center for Transportation and Logistics, writes for The Hill about how environmental, social and governance (ESG) criteria impacts global supply chain managers and their sustainability efforts. “From 2020 to 2021, we observed that investors were by far the fastest-growing driver of sustainability pressure on firms,” writes Correll. “At the same, the understanding of what exactly ESG and supply chain sustainability entails changes depending on the geography, industry and year that we ask.”
Boston Metal, an MIT startup, is working to transition the steel industry from coal-based fuel to sustainably produced electricity, reports Scott Kirsner for The Boston Globe. The “key to making iron and steel production less environmentally damaging is getting access to sustainable power from wind, solar, hydro, or nuclear, and finding ways to store that power to use when it’s needed, such as in large-scale batteries,” explains Kirsner.
