Climate change

Prof. Jessika Trancik speaks with Forbes contributor Peter Cohan about the carbon emissions associated with gas, hybrid and electric vehicles, and the site she and her research group developed to allow consumers to compare personal vehicles against climate change mitigation targets. “In most locations, compared to [gas-powered vehicles], EVs produce emissions savings greater than 30%,” says Trancik. "Most savings are greater depending on the geographic location, the electricity supply, and the vehicle model.”

MIT researchers have found that zeolite, a material used to soak up odors in kitty litter, can be used to grab methane out of the air, reports Angely Mercado for Gizmodo.  “Zeolite has tiny pores that act like sponge, and the clay is pretty multifunctional: It can help improve water retention in soil, and it’s found in natural kitty litter,” explains Mercado.

WBUR reporter Bruce Gellerman spotlights a new report by MIT Energy Initiative (MITEI) researchers that emphasizes the importance of developing and deploying new ways to store renewable energy in order to transition to clean energy. “There are a variety of technologies and if we can develop [them] and drive those costs down, it could make getting to net-zero or zero in the electricity sector more affordable,” says Prof. Robert Armstrong, MITEI director.

A new report by researchers from MIT’s Energy Initiative (MITEI) underscores the feasibility of using energy storage systems to almost completely eliminate the need for fossil fuels to operate regional power grids, reports David Abel for The Boston Globe. “Our study finds that energy storage can help [renewable energy]-dominated electricity systems balance electricity supply and demand while maintaining reliability in a cost-effective manner,” says Prof. Robert Armstrong, director of MITEI.

Boston Metal, an MIT spinout, has created a new manufacturing method that could help engineers reshape the way in which alloy is made, reports Marcello Rossi for The Atlantic. The process is “called ‘molten oxide electrolysis,’ in which a current moves through a cell containing iron ore,” explains Rossi.

Wall Street Journal reporter Ryan Dezember visited Prof. Desiree Plata’s lab to learn more about her group’s work developing a new tool to help address climate change. Plata and her colleagues “soaked an odor-eating clay used in cat boxes in a copper solution to create a compound that they say snatches methane from passing air and turns it into carbon dioxide, a much less harmful greenhouse gas.” The new technique has the “potential to greatly reduce the amount of methane in the atmosphere and slow warming temperatures on the planet.”

Researchers at MIT have built a highly efficient thermophotovoltaic cell that converts incoming photons to electricity, reports Kevin Hurler for Gizmodo. “We developed this technology—thermal batteries—because storing energy as heat rather than storing it electrochemically is 10 to 100 times cheaper," explains Prof. Asegun Henry. 

In an article for The Hill, Prof. Emeritus Henry Jacoby writes that “government agencies, even as they act to protect U.S. interests, need to try to maintain conditions favorable for international climate research efforts.”

Prof. Yet-Ming Chiang ’85, Prof. Craig Carter and Throop Wilder co-founded MIT spinout 24M, which “will manufacture next-generation lithium-ion batteries using its cell technology,” reports Reuters.  

“MIT researchers concluded wood burns dirtier than coal, and determined it takes at least 44 years for replanted trees to adsorb the carbon released from burning the ones they replaced,” reports CBS News correspondent Jonathan Vigliotti.

Bruce Anderson ’73, founder and CEO of MIT spinout 247 Solar, speaks with Bloomberg Baystate Business Hour host Janet Wu about the power of solar energy and growing climate concerns for the future. “We are facing dire circumstances here,” says Anderson. “We have no clue what the climate’s tipping point is where it all of sudden goes in a direction that we cannot recover from, no matter how much carbon we remove from the air."

Lecturer Susan Murcott and graduate student Imane Ait Mbiriq speak with Paris Alston and Jeremy Siegel of GBH’s Morning Edition about the MIT Climate Clock, a creation from the D-Lab that will be projected on the Green Building through May 27. “Our overall vision is that we have climate clocks in every K-12 school, in every university campus in the United States and even in the world, so that people can wake up to the reality of this new age and take action,” says Murcott.

MIT President L. Rafael Reif and Special Presidential Envoy for Climate John Kerry discussed the urgency of addressing climate change during the Climate Grand Challenges Showcase event, reports Chris Lisinski for the State House News Service. “Climate change has been called a ‘super wicked’ problem. In Boston, that might sound like a local way of saying ‘really hard,’ but this phrase is actually a technical term,” Reif said. “It describes any enormously complex societal problem that has no single right answer and no clear finish line as well as multiple stakeholders with conflicting priorities and no central authority empowered to solve it.”

Bloomberg News reporter Janet Wu speaks with President L. Rafael Reif and Special Presidential Envoy for Climate John Kerry during the Institute’s Climate Grand Challenges showcase event. “If you can capture the emissions -- literally, genuinely -- then you’re reducing the problem,” said Kerry of the importance of eliminating greenhouse gas emissions.

Prof. Jessika Trancik speaks with ABC News about the urgent need to transition to renewable energy sources, and how we can build a future powered by alternative energy. “Up until recently there were really significant questions about whether we could transition to another [energy] foundation,” says Trancik. “This question has now been answered in that we now have cost competitive renewable primary energy in the form of solar and wind energy and also in other types of renewable energy.”
