24M, an MIT startup, has been named to Fast Company’s list of the most innovative companies in the energy space for 2025, reports Alex Pasternack. The company “has been developing a portfolio of battery technologies designed to make batteries that are safer, cheaper, cleaner, and longer-lasting,” explains Pasternack. “Its technologies include a semisolid electrode for conventional and novel battery chemistries, which gives the battery more energy density and requires fewer materials, and a unique separator that monitors the cell and helps prevent the aberrations that cause shorts and fires.” 

Mohamed Elrefaie speaks with Automotive World reporter Will Girling about his work developing an open-source dataset of 8,000 car designs, including their aerodynamic characteristics, which could be used to develop novel car designs in a more efficient manner. “If an automaker wants to reduce drag and improve performance, it can guide the GenAI model to produce those specific designs,” Elrefaie explains. “The standard development cycle for a design using legacy tools can take anywhere from three to five years, as it requires collaboration between many specialized departments. With AI, you could validate up to 600 designs in just one or two minutes.”

David Zipper, a senior fellow at the Mobility Initiative, speaks with WBUR Here & Now co-host Scott Tong about “car bloat,” the trend of increasingly large SUVs and trucks on the road. “I personally believe that car bloat is a major public health issue, it's a major policy issue, but I'll be candid, I don't think the average American does right now,” explains Zipper. “We need people to understand it and appreciate it. And in my view, that's going to need to happen at the grassroots level before we can expect really anybody in Washington to address this problem in the way that it deserves to be addressed.”

David Zipper, a senior fellow at the Mobility Initative, writes for Fast Company about the future of the electric vehicle market. “With EVs comprising less than one in ten new car purchases, most Americans are still forming their impressions and figuring out how to evaluate them,” writes Zipper. “It remains to be seen whether they’ll ultimately care most about range, engine power, or something else entirely.” 

Prof. Jessika Trancik speaks with BBC reporter Isabelle Gerretsen about the future of electric vehicles and how shifting to EVs can help reduce carbon emissions. Trancik and her research lab developed an online tool, dubbed Carboncounter, that can analyze the climate impact of different vehicles. “A shift to an electric vehicle is one of the single most impactful decisions that someone can make if they want to reduce their own emissions," explains Trancik. 

David Zipper, a senior fellow at the MIT Mobility Initiative, speaks with ABC News reporter Michael Dobuski about the rising popularity of small “micromobility” vehicles. “In the last fifteen years or so, you’ve seen a lot of cities in the US, and frankly in other parts of the world too, invest a lot of money and resources in creating safe spaces for people who want to use a scooter, or a bicycle, or any of these other versions of micromobility that we’re talking about,” explains Zipper. 

MIT startup, 24M, has designed an EV battery with a range of 1,000 miles on a single charge, reports Adele Peters for Fast Company. “The extra-long range also can help the car’s battery last much longer,” explains Peters. “If you use a rapid charger to fully charge a battery, it can damage the battery, meaning it won’t last as long. Because it has such a long range, the new battery should rarely need a full rapid charge.”

Researchers at MIT have developed a cathode, the negatively-charged part of an EV lithium-ion battery, using “small organic molecules instead of cobalt,” reports Hannah Northey for Energy Wire. The organic material, "would be used in an EV and cycled thousands of times throughout the car’s lifespan, thereby reducing the carbon footprint and avoiding the need to mine for cobalt,” writes Northey. 

Prof. Jessika Trancik writes for Newsweek about the importance of government policy in supporting the transition to electric vehicles. “Policy is needed to make EVs widely accessible to people while the technology and markets continue to mature,” writes Trancik, “and to ensure the process moves quickly enough to help slow the build-up of greenhouse gases in the atmosphere.”

Prof. Jessika Trancik speaks with Associated Press reporter Alexa St. John to discuss electric vehicle emissions and ownership costs. Trancik notes, “buyers should consider total cost of ownership, which for an EV is generally less than that of a gas-powered counterpart due to savings on maintenance and fuel.”

David Zipper, a senior fellow at the MIT Mobility Initiative, speaks with Kai Ryssdal of Marketplace about how cars in the U.S. are getting heavier and larger, and the environmental and safety costs associated with larger vehicles. “For decades, people who buy enormous, very heavy cars have been creating societal costs that they aren’t paying for. That’s what’s called a market failure,” said Zipper. “So if you want the market for automobiles to succeed, we need to make sure that when people are shopping for their next car, they are considering the societal costs of their purchase.”

Prof. Jessika Trancik speaks with Bloomberg reporter Kyle Stock about the importance of scrappage programs, especially those that incentivize electrifying the current fleet of vehicles in the United States. “At any given point in time, you care about the composition of the fleet,” says Trancik. “Funding programs that would help turn over the fleet more rapidly makes a lot of sense.”

Studies by researchers at MIT have found “that shifting to electric vehicles delivers a 30% to 50% reduction in greenhouse gas emissions over combustion vehicles,” reports Tom Krisher for Associated Press. According to Prof. Jessika Trancik, “electric vehicles are cleaner over their lifetimes, even after taking into account the pollution caused by the mining of metals for batteries,” writes Krisher.

Prof. Jessika Trancik speaks with Popular Science reporter Charlotte Hu about the impact of electric vehicles on the environment. “There’s definitely a number of different modes of transport that need to be addressed and green modes of transport that need to be supported,” says Trancik. “We really need to be thinking holistically about all these ways to reduce greenhouse gas emissions.”

MIT researchers have found that by “encouraging strategic EV charging placement, rather than allowing EV chargers to be situated merely due to charging company convenience or preferences” it may be possible to “mitigate or eliminate EV charging problems without the need for advanced technological systems of connected devices and real-time communications, which could add to costs and energy consumption,” reports Carolyn Fortuna for CleanTechnica.
