Renewable energy

Prof. Emeritus Donald Sadoway co-founded Boston Metal, an MIT startup that has developed a carbon-free steel manufacturing process, reports Amy Feldman for Forbes. “Boston Metal’s process – which uses an electricity conducting, molten-metal proof anode to liquify iron ore, separating the pure metal without harmful byproducts – allows factories to create carbon-free steel as long as they use a clean energy source, such as hydroelectric power,” explains Feldman. “It also can create steel from lower-grade ores rather than relying on scarce high-grade ones. That’s an important advantage in terms of both cost and availability compared to other methods of making green steel, according to the company.”

Writing for The Hill, Prof. Christopher Knittel and graduate student Kailin Graham emphasize the importance of ensuring the transition away from fossil fuels is an equitable process that provides support for vulnerable workers. “If we’re serious about achieving a truly just transition, far more federal policy action is needed,” they write.

Prof. Ernest Moniz and his colleagues have designed a new consortium that plans to create an organized market for hydrogen, reports Llewellyn King for Forbes. This will allow hydrogen to become “a viable option in the pursuit of net-zero emissions,” writes King.

A study by MIT researchers has uncovered an, “intricate relationship between jobs and the nation’s energy transition,” reports Kaleigh Harrison for Environment + Energy Leader. The study, “presents an unprecedented county-level examination of the U.S., identifying regions most intertwined with fossil fuels – ranging from intensive drilling and mining operations to heavy manufacturing sectors,” writes Harrison. “The findings underscore not only the expected impact on traditional energy bastions but also highlight the broader, often overlooked, implications for areas heavily invested in manufacturing.”

Fast Company reporter Kristin Toussaint spotlights how MIT researchers have developed a new map detailing how the shift to clean energy could impact jobs around the country. The researchers found that workers could be most impacted in areas that drill for oil and gas, as well as “regions with a high concentration of manufacturing, agriculture, and construction—all industries that rely heavily on coal, oil, and gas.” 

Fast Company reporter Adele Peters spotlights Boston Metal – an MIT startup that uses electrolysis to heat iron ore and create liquid steel without releasing carbon emissions. “If the process runs on renewable energy, the steel is zero-emissions,” explains Peters. “The same technique can be used to extract other valuable metals from mining waste.”

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.”

Robert Stoner, interim director of the MIT Energy Initiative, speaks with Boston Public Radio hosts Margery Eagan and Jim Braude to discuss the climate crisis and some solutions being developed at MIT. "You have to be [optimistic]," says Stoner. "I do feel there are technological pathways that we can go down and get there. Solar and wind and storage get us an awful long way. We have to make these things cheaper, and there are an awful lot of people at MIT and at other great universities, and many companies, hammering away at those problems."

ClimateWire reporter John Fialka writes that MIT engineers have developed a new process to convert carbon dioxide into a powder that can be safely stored for decades. “The MIT process gets closer to an ambitious dream: turning captured CO2 into a feedstock for clean fuel that replaces conventional batteries and stores electricity for months or years,” writes Fialka. “That could fill gaps in the nation's power grids as they transition from fossil fuels to intermittent solar and wind energy.”

Fast Company reporter Adele Peters spotlights how researchers at MIT have combined cement with carbon black to make concrete that can store energy as one of the climate tech innovations that provide hope “that it’s still possible to avoid the worst impacts of climate change.” With this new technology, “the foundation of your future house could eventually store solar power from your roof,” explains Peters.

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.”

Principal Research Scientist Emre Gençer speaks with The Independent reporter Louise Boyle about natural hydrogen and its potential as a future renewable energy source. “There is a ‘mismatch’ where natural hydrogen is being discovered and where it could be used, which would require massive investments in completely new infrastructure,” says Gençer. “I think it will be part of the solution but we need to take it with a grain of salt.”

MIT researchers have developed a supercapacitor comprised of concrete and charcoal, that can store electricity and discharge as needed, reports Aleks Phillips for Newsweek. Researchers hope the device can provide “a cheap and architectural way of saving renewable energy from going to waste,” writes Phillips.

Johanna Mayer and Katie Hafner from Scientific American’s “The Lost Women of Science podcast spotlight the late former Prof. Mária Telkes and her work focused on the development of solar energy. “Dr. Mária Telkes died in 1995, at age 94,” says Mayer. “But her legacy lives on. Today, the number of people installing solar panels in their homes is consistently rising – and in a recent Pew study, 39% of homeowners surveyed said they were seriously considering going solar.”

Researchers at MIT have developed a conceptual design for a system that can efficiently produce “solar thermochemical hydrogen,” reports Xinhua. “The system harnesses the Sun's heat to directly split water and generate hydrogen -- a clean fuel that can power long-distance trucks, ships, and planes, while in the process emitting no greenhouse gas emissions.”
