Alternative energy

Prof. Asegun Henry founded Fourth Power, a startup using new technology to cut the cost of storing renewable energy, reports Adele Peters for Fast Company.  The technology is designed “to tap into excess renewable energy,” explains Peters. “That energy heats up liquid tin, which flows down carbon pipes to heat up the blocks. When the grid needs electricity again, the system generates it using special solar panels that run on the white-hot light from the pipes rather than sunshine. Because the system was designed for durability, the team expects it to last for three decades—far longer than lithium-ion batteries, which quickly degrade.”

An analysis by The Atlantic’s Ronald Brownstein notes despite Republican resistance to electric vehicles, many new production facilities are located in GOP-represented states. MIT Innovation Fellow Brian Deese explains EV companies are simply seeking space and nearby manufacturing and construction capacity, but said “it’s pretty hard to think of a technology where there was a cheaper, better technology to solve a consumer need and consumers prioritized a cultural or political patina over lower costs and higher quality.”

Prof. Jacopo Buongiorno talks with Steve Curwood of Living on Earth about new investments in nuclear power generation, advanced reactors and waste disposal. He notes roughly half the clean energy in the U.S. comes from nuclear, with great potential due to its adaptability. “The nice thing about nuclear is that it’s a fairly versatile energy source,” explains Buongiorno. “It can give you heat, if you want heat. It can give you electricity if you want electricity. It can give you hydrogen if you need hydrogen, or some kind of synthetic fuel for transportation." 

Prof. Christopher Knittel speaks with The Hill reporters Rachel Frazin and Zack Budryk about the implications of the latest climate rule put in place to mitigate power plant emissions. “What we’ve seen, even without these rules, is that coal generation is failing,” says Knittel. “These new rules will certainly push to speed that transition up.”

Robert Stoner, interim director of the MIT Energy Initiative, speaks with Boston Public Radio hosts Jim Braude and Margery Eagan about how the Bipartisan Infrastructure Act provides funding for hydrogen hubs around the country to create networks of hydrogen fuel producers. “We're going to use hydrogen as a substitute for natural gas. In order for that to happen, we have to get the cost way down,” Stoner explains.

Researchers from MIT and elsewhere explored the effectiveness of climate commitments made by banks to mitigate the effects of climate change, reports Nicole Goodkind for CNN. “Our results cast doubt on the efficacy of voluntary climate commitments for reducing financed emissions, whether through divestment or engagement,” the researchers note.

Researchers from MIT and elsewhere have found that climate pledges made by banks to reduce carbon emissions and finance energy transitions may not be as effective as previously thought, reports Eshe Nelson for The New York Times. “The researchers found that since 2018 the banks had reduced lending 20 percent to sectors they had targeted in their climate goals, such as oil and gas and transport,” explains Nelson. “That seems like progress, but the researchers argued it was not sufficient because the decline was the same for banks that had not made the same commitment.”

Senior Lecturer John Parsons speaks with Grist reporter Gautama Mehta about the future of nuclear energy in the United States. “It’s also possible that nuclear, if we can do it, is a valuable contribution to the system, but we need to learn how to do it cheaper than we’ve done so far,” explains Parsons. “I would hate to throw away all the gains that we’ve learned from doing it.”

Using microwave plasma technology developed at MIT, 6K inc., is turning metals “including scrap, into high-performance materials for various applications,” reports Alex Pasternack for Fast Company. “The process produces no salt or liquid waste, uses just 10% of the water and half of the energy of conventional processes, and reduces costs by half,” writes Pasternack. “Its technique can also precisely control the composition and structure of materials at the atomic level.”

Radia, an energy startup founded by Mark Lundstrom '91, SM '93, MBA '93, has developed the “Windrunner,” an airplane designed to deliver 300-foot-blades directly to wind farms, reports Maureen O’Hare for CNN. The plane will “help the world meet its decarbonization targets, it’ll use sustainable aviation fuel and need only a simple packed-dirt or gravel runway to land on,” writes O’Hare.

Radia – a startup founded by Mark Lundstrom '91, SM '93, MBA '93 – has unveiled the “WindRunner,” a large cargo plane equipped with wind turbine blades aimed at transforming wind energy across the United States, reports Jennifer Hiller and Brian McGill for The Washington Post. “Radia estimates the larger turbines could reduce the cost of energy by up to 35% and increase the consistency of power generation by 20% compared with today’s onshore turbines,” they write. 

Paris Smalls PhD '22 founded Eden GeoPower – a startup that uses “a new kind of fracking that uses jolts of electricity, rather than blasts of water, to shatter underground rocks,” reports Hiawatha Bray for The Boston Globe. “While the process can work for extracting oil and natural gas, Smalls mainly wants to tap into a squeaky-clean energy source — the natural heat of the planet’s crust,” writes Bray.

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.

Prof. Yet-Ming Chiang has been named to the TIME 100 Climate list, which highlights the world’s most influential climate leaders in business. “When it comes to cleantech, if it won’t scale, it doesn’t matter,” Chiang says. “This is a team sport—companies large and small, and governments state and federal, need to work together to get these new technologies out there where they can have impact.” 

Prof. Jacopo Buongiorno speaks with Danny Lewis, host of The Wall Street Journal’s “Future of Everything” podcast, about the future of nuclear power plants. “As countries, regions, businesses contemplate their future plans for reducing carbon emissions, nuclear is one technology that they have got to consider,” says Buongiorno. “It's an incredibly dense energy source, so you don't need a big supply chain that continuously feeds the power plant with fuel, the same way that you would with coal, for example. Also, the machine itself, the reactor is very, very compact.”
