Energy

Boston Globe correspondent Scott Kirsner spotlights CubicPV, an MIT startup, which is creating solar cells that more efficiently convert sunlight into energy.

Washington Post columnist David Von Drehle spotlights MIT startup Form Energy, which has created a battery prototype made of iron and oxygen that stores large amounts of power and can release it over days. Von Drehle writes that this new battery could usher in a “sort of tipping point for green energy: reliable power from renewable sources at less than $20 per kilowatt-hour.”

Wall Street Journal reporter Russell Gold spotlights how Form Energy, a startup co-founded by Prof. Yet-Ming Chiang, has developed an inexpensive iron-air battery that can discharge power for days. The batteries could be “capable of solving one of the most elusive problems facing renewable energy: cheaply storing large amounts of electricity to power grids when the sun isn’t shining and wind isn’t blowing,” writes Gold.

Sergey Paltsev, deputy director of the MIT Joint Program on the Science and Policy of Global Change, emphasizes the importance of reaching net-zero emissions as fast as possible. “By pushing natural gas—which is indeed cleaner than coal, but it’s still a fossil fuel that releases a lot of CO2 and more importantly, a lot of methane—we are actually hurting renewables,” says Paltsev. 

Writing for The Hill, Prof. Sanjoy Mitter, Prof. Munther Dahleh, research affiliate Le Xie and their colleagues underscore the need to build a “resilient energy ‘superhighway,’ an electric grid that delivers a wide portfolio of energy supplies to the end users in a reliable manner.” They add that: “Investments are needed both in building the backbone interconnections, as well as in upgrading the ‘last mile’ distribution grid.”

UPI reporter Brian Dunleavy writes that MIT researchers have developed a new way to potentially expand sources of biofuel to include straw and woody plants. "Our goal is to extend this technology to other organisms that are better suited for the production of these heavy fuels, like oils, diesel and jet fuel," explains Prof. Gregory Stephanopoulos.

MIT has announced a new climate action plan aimed at helping the Institute tackle climate change, reports Kristina Chen for The Tech. The plan offers increased opportunities for student involvement and a new organizational structure. Maria Zuber, MIT’s vice president for research, explains that MIT feels “that it’s our responsibility and duty to try to make a genuine difference, and to do that, we’re going to need the help of everyone in the community.” 

Prof. Jacopo Buongiorno speaks with National Geographic reporter Lois Parshley about the future of nuclear energy in the U.S. and western Europe. “Our analysis shows a big share of nuclear, a big share of renewables, and some storage is the best mix that is low-carbon, reliable, and at the lowest cost,” says Buongiorno of an MIT report showing the most cost-efficient, reliable grid comes from an energy mix.  

Prof. Jessika Trancik speaks with Vox contributor David Roberts about the various aspects involved with transforming our world in response to climate change. “There is so much potential, but we really need to be more deliberate about how we are thinking about technology and that means understanding what it is, how it evolves and how we can push it faster towards these beneficial solutions,” says Trancik of the transition to clean energy technologies.

Prof. Robert Jaffe speaks with CNN reporter Stephanie Bailey for a piece that explores how the rivalry between Edison, Tesla and Westinghouse helped lead to transformations in the development of electricity. Bailey also features alumnus Joel Jean and his solar tech startup.

On The Interchange podcast, Prof. Jessika Trancik discusses her research exploring the cost declines in lithium-ion batteries and what it will take to reach mass-market adoption of electric vehicles.

Writing for The Conversation, Prof. Jessika Trancik explores how government policies can spark innovation in clean energy markets, helping to reduce carbon emissions. “Left to its own devices, technological change will not necessarily solve climate change, especially not in the limited time we have left to act,” writes Trancik. “But my research on technology evolution suggests that government policy can help propel this powerful process toward rapid progress and beneficial outcomes.”

A new study by Prof. Jessika Trancik and postdoctoral associate Micah Ziegler examining the plunge in lithium-ion battery costs finds that “every time output doubles, as it did five times between 2006 and 2016, battery prices fall by about a quarter,” reports The Economist. “A doubling in technological know-how, measured by patent filings, is associated with a 40% drop in price.”

MIT researchers have analyzed the role of long-duration energy storage technologies and found that large storage systems have the potential to lower electricity prices in a carbon-free grid by up to 40%, writes Eric Roston for Bloomberg. 

A study by researchers from MIT, Yale and Purdue finds that leaving the camera on during video meetings is a contributor to carbon dioxide emissions, reports Hannah Smothers for Vice. “Just one hour of videoconferencing or streaming, for example, emits 150-1,000 grams of carbon dioxide (a gallon of gasoline burned from a car emits about 8,887 grams), requires 2-12 liters of water and demands a land area adding up to about the size of an iPad Mini,” the researchers write.
