MIT spinoff Commonwealth Fusion System has made its first direct corporate power purchase agreement with Google, reports Timothy Gardner for Reuters. Google plans to buy 200 megawatts of fusion power from Commonwealth Fusion Systems’ first grid-scale fusion power plant in Chesterfield County, Virginia.
Noman Bashir, a fellow with the MIT Climate and Sustainability Consortium and a postdoc at CSAIL, speaks with Wired reporter Molly Taft about AI and energy consumption. Bashir explains that how quickly a model answers a question has a big impact on its energy use. “The goal is to provide all of this inference the quickest way possible so that you don’t leave their platform,” Bashir says. “If ChatGPT suddenly starts giving you a response after five minutes, you will go to some other tool that is giving you an immediate response.”
Vijay Gadepally, a senior scientist at MIT Lincoln Lab, discusses users can help conserve energy while using AI tools, reports Nicolás Rivero for The Washington Post. Gadepally notes that users can save energy by asking the AI to be concise when you don’t need long answers, as models use more energy for each word they process. “People often mistake these things as having some sort of sentience,” says Gadepally. “You don’t need to say ‘please’ and ‘thank you.’ It’s okay. They don’t mind.”
Prof. Yet-Ming Chiang, Shreya Dave '09, SM ’12, PhD '16, Bob Mumgaard SM '15, PhD '15 and Sloan alumna Emily Reichert have been named to the 2025 Boston Globe Tech Power Players list for their efforts in the energy sector, reports Hiawatha Bray for The Boston Globe. Chiang emphasizes the importance of federal funding in advancing scientific research. “My entire career has been supported by US taxpayers,” Chiang says. “The ability to give back and develop technologies and create jobs, that’s a big motivator for me.”
Prof. Daniela Rus, director of CSAIL, and research affiliate Ramin Hasani have been named to The Boston Globe’s 2025 list of Tech Power Players working in the foundational AI sector, reports Aaron Pressman for The Boston Globe. Rus and Hasani are co-founders of Liquid AI, a startup that has developed “an AI technique with fewer software ‘neurons’ than large language models of OpenAI and others,” explains Pressman. This means “Liquid AI requires less computing power (and electricity.)”
Prof. Yet-Ming Chiang and his colleagues have developed a sodium-air fuel cell that “packs three to four times more energy per pound than common lithium-ion batteries,” reports Aaron Pressman for The Boston Globe, which could serve as “a potentially groundbreaking clean power source for airplanes.” Pressman adds that: “Ultimately, a sodium-air fuel cell could power a regional jet carrying 50 to 100 passengers on flights as long as 300 miles.”
MIT researchers have developed a new membrane that can separate different kinds of fuel by molecular size, which could replace the current energy-intensive crude oil distillation process. “Roughly 1 percent of global energy use goes into separating crude oil into gasoline, diesel, and heating oil,” writes Aamir Khollam for Interesting Engineering. This new membrane “excelled in lab tests…[and] effectively separated real industrial oil samples containing naphtha, kerosene, and diesel.”
Prof. Christopher Knittel joins the Marketplace podcast “Make Me Smart” to discuss how the U.S. can be in the best position for global energy dominance. “The world is switching to electric vehicles, the world is switching to solar and wind,” says Knittel. “And the less we do domestically, the less capability we build domestically to provide those clean energy resources, the worse off our industries will be in the future.”
Anantha Chandrakasan, MIT’s chief innovation and strategy officer and dean of MIT’s School of Engineering, speaks with Boston Globe reporter Jon Chesto about the new MIT-GE Vernova Energy and Climate Alliance. “A great amount of innovation happens in academia. We have a longer view into the future,” says Chandrakasan. He adds that while companies like GE Vernova have “the ability to get products out quickly to scale up, to manufacture, we have the ability to think past the short-term. ... It’s super smart of them to surround themselves with this incredible talent in academia. That will allow us to make the kind of breakthroughs that will keep U.S. competitiveness at its peak.”
E&E News reporter Christa Marshall writes that the new MIT-GE Vernova Energy and Climate Alliance will “scale sustainable energy systems across the globe” and advance breakthrough low-carbon technologies.
Lee Selwyn PhD '69 speaks with WVCB reporter Ben Simmoneau about how gas companies in Massachusetts promised consumers discounts on their March and April bills, following soaring energy costs this winter.
Sloan Lecturer Harvey Michaels speaks with Boston Globe reporter Scooty Nickerson about skyrocketing energy costs in Massachusetts. Michaels explains that one contributing factor is the vast but costly energy system that can supply heat during cold dips but is expensive to maintain. “It’s like having a fleet of planes flying around with very few passengers on them,” Michaels explains. “It’s going to be very expensive for the passengers that do fly” to make it worth it.
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.”
New Yorker reporter Brent Crane spotlights Quaise Energy, an MIT geothermal energy startup founded by Carlos Araque BS '01, MS '02. Crane explains that central to Quaise’s system is the gyrotron, a tubular device that “works like a very, very powerful microwave, emitting ‘millimeter waves’ that would vaporize your vegetables; they can generate temperatures of a hundred million degrees Celsius.” Crane notes that: “About a decade ago, Paul Woskov, an MIT research engineer, showed that the technology could be used for ‘energy drilling’ without a physical bit. Quaise’s scientists propose that the heat of a gyrotron could stabilize tunnel walls by vitrifying them into glass.”
Researchers at MIT have developed a new chip-based system capable of improving “how terahertz (THz) waves pass through silicon chips,” reports Rupendra Brahambhatt for Interesting Engineering. The researchers “applied a principle called matching, which involves reducing the difference between silicon (dielectric constant is 11) and air (dielectric constant is 1) so that more waves can travel through,” writes Brahambhatt.
