Energy

Grist reporter Matt Simon spotlights a new study co-authored by MIT researchers that finds “large-scale deployment of long-duration energy storage isn’t just feasible but essential for renewables to reach their full potential, and would even cut utility bills.” Graduate student Martin Staadecker explains: “Battery storage on its own — or what people call short-duration energy storage — is very important. But you can’t just rely on lithium-ion batteries, because it would be very expensive to have enough to actually provide power for an entire week.”

Prof. Jessika Trancik speaks with ABC News reporter Julia Jacobo about the role of green hydrogen in decarbonization efforts. “Hydrogen itself could be a really important component to a green transition,” says Trancik. 

Joe Higgins, MIT’s vice president for campus services and stewardship, speaks with Boston Globe reporter Sabrina Shankman about the Consortium for Climate Solutions, a new effort led by MIT, Harvard and Mass General Brigham to enable the development of large-scale renewable energy projects. “The science is telling us that we need to triple the amount of renewable energy on the power grids by 2030 and it’s not happening fast enough,” says Higgins. “It really came down to, we need new models … and how do we come together to do that with much greater impact, at a much greater speed?”

The Consortium for Climate Solutions, which is led by MIT, Harvard and Mass General Brigham, is enabling the development of a solar farm in Texas and a wind farm in North Dakota, which should generate enough renewable energy annually to power 130,000 homes, reports Martha Bebinger for WBUR. The effort is intended to “cut annual carbon dioxide emissions by 950,000 tons, about the equivalent of the carbon that trees covering 600,000 acres of forest would absorb in a year.”

Researchers at MIT have developed a “new type of transistor using semiconductor nanowires made up of gallium antimonide and iridium arsenide,” reports Alex Knapp for Forbes. “The transistors were designed to take advantage of a property called quantum tunneling to move electricity through transistors,” explains Knapp. 

Writing for MarketWatch, Joseph Coughlin, director of the MIT AgeLab, examines how the revival of nuclear power could be beneficial for older workers with expertise in the industry. “The myth of older workers taking up space must end in every industry, but in a high-stakes sector such as nuclear power, older workers aren’t taking up space — they are a critical part of the future," writes Coughlin. 

Prof. Christopher Reinhart speaks with GBH reporter Craig LeMoult about the feasibility of harvesting energy from the Charles River. Reinhart notes that using renewable heat pumps along with the old, existing steam infrastructure could be a good option for Boston and other cities around the country that have district energy systems. “I think you would see a lot of those, especially with the overall push towards decarbonization,” says Reinhart.  

Prof. Jacopo Buongiorno speaks with Nature reporter Davide Castelvecchi about how AI has increased energy demand and the future of nuclear energy. 

Fast Company reporter Kristin Toussaint spotlights a new study by MIT researchers that examines the energy burden in the U.S., the percent of a household’s income spent on energy costs. The researchers found a disproportionate number of people in the South experiencing energy poverty. “As the climate warms, we’re going to need to use more and more energy on air-conditioning, and that’s going to increase the burden on low-income households,” explains Prof. Christopher Knittel. 

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. 

Writing for The Washington Post, Prof. Daniela Rus, director of CSAIL, and Nico Enriquez, a graduate student at Stanford, make the case that the United States should not only be building more efficient AI software and better computer chips, but also creating “interstate-type corridors to transmit sufficient, reliable power to our data centers.” They emphasize: “The United States has the talent, investor base, corporations and research institutions to write the most advanced AI models. But without a powerful data highway system, our great technology advances will be confined to back roads.”

Graduate student Zoe Fisher speaks with Yusuf Khan of The Wall Street Journal’s  about what inspired her to pursue a career in nuclear engineering, noting that being able to fight climate change firsthand is one of the key reasons she wanted to make a career in nuclear.. “It’s a cool thing to study that is going to have a lot of broader impacts,” Fisher says.

Prof. Asegun Henry has been named a 2024 Grist honoree for his work developing a “sun in a box,” a new cost-effective system for storing renewable energy, reports Grist. Based on his research, Prof. Henry has founded Fourth Power, a startup working to build a prototype system that will hopefully “allow us to decarbonize electricity,” says Henry. 

Prof. Michael Strano joins “Somewhere on Earth” podcast host Gareth Mitchell to discuss how he and his colleagues developed tiny batteries that could be used to power cell-sized robots. Roughly the thickness of a human hair, the new battery can create a current by capturing oxygen. “I would say we're making the LEGOs, the building blocks that go into robots,” Strano says. “We’re building the parts and it's an exciting time for the field.”

Anurag Bajpayee MS '08, PhD '12 and Prakash Govindan PhD '12 founded Gradiant, an MIT startup “trying to reduce both costs and energy while eliminating chemicals” in water, reports Diana Olick for CNBC. “We take highly contaminated wastewater which contains solvents, which contains dissolved salt, which contains organics, and we eliminate the entire liquid waste,” says Govindan.
