Prof. Christopher Knittel speaks with Andy Uhler of Marketplace about gasoline process and the crack spread, the difference between the cost of oil and the cost to refine it. “Increases in the crack spread that we’ve seen recently has been just supply and demand,” said Knittel.
Postdoctoral researcher Murat Onen and his colleagues have created “a nanoscale resistor that transmits protons from one terminal to another,” reports Alex Wilkins for New Scientist. “The resistor uses powerful electric fields to transport protons at very high speeds without damaging or breaking the resistor itself, a problem previous solid-state proton resistors had suffered from,” explains Wilkins.
Commonwealth Fusion Systems (CFS), an MIT spinout, has signed an agreement with the U.K. Atomic Energy Authority (UKAEA) to “support the fastest path to clean commercial fusion energy,” reports Ed Browne for Newsweek. “CFS says its agreement with UKAEA could involve exchanges of knowledge and collaboration on things like fuel, modeling, manufacturing and maintenance,” writes Browne.
Postdoctoral fellow Joshua A. Schwartz and University of Pennsylvania PhD candidate Sabrina B. Arias write for The Washington Post about their research exploring how American cities and towns are taking action to help reduce carbon emissions. “Major urban areas account for about 30 percent of the U.S. carbon footprint,” they write. “This means even relatively narrow efforts focused on those cities could still have a significant impact.”
Ross Trethewey, co-host of This Old House, visits Prof. Vladimir Bulović, director of MIT.nano, to learn more about the future of solar technology, including an electricity-generating film that can be applied to windows and other materials. “Dramatic advancements are on the horizon,” says Bulović. “We can make solar cells that don’t weigh very much at all so deployment of them on top of your roof could be as simple as unrolling a carpet and stapling it to the roof with a plug. Maybe your windows will be turned into solar cells.”
Writing for The Boston Globe, Prof. Ernest Moniz, former secretary of energy, makes the case for addressing climate change and energy insecurity collectively. “US decision makers in the public and private sector need to implement data-driven plans that reflect real needs and enable a credible and sustained energy transition to zero-carbon energy in the mid-century time frame,” writes Moniz.
TechCrunch reporter Devin Coldewey writes that a new report by MIT researchers finds that in order to successfully transition to a renewable energy grid, the federal government must intervene to help build green energy storage at a scale that will meet the nation’s needs. “The federal government has the means both to subsidize the utilization of existing storage options and to fund intensive research into new and promising ones,” writes Coldewey of the report’s findings.
Ambri, an MIT startup that has developed a liquid-metal battery that can be used for grid-level storage of renewable energy, has announced that it is months away from delivering its first battery to a customer, reports Jacob Wycoff for CBS Boston. "We want to have a battery that can draw from the sun even when the sun doesn't shine," said Prof. Donald Sadoway of the inspiration for Ambri’s battery.
Prof. David Hsu weighs in on how the current competitive utility prices may not survive the anticipated shocks to the energy market, reports Dharna Noor for The Boston Globe. Hsu explains that “aggregation is a useful tool to clean the grid and boost local control of energy – and customers can always opt out to take advantage of lower rates,” writes Noor.
Infinite Cooling, an MIT startup, is developing a new system that can capture water from cooling tower plumes and could significantly reduce water consumption in evaporative cooling tower systems, reports Sonal Patel for Power Magazine. “The technology that is developed could lead to significant water savings and improve water quality with minimal energy cost,” explained members of Prof. Kripa Varanasi’s lab.
Siblings Gia Schneider ‘99 and Abe Schneider SM ‘03 co-founded Natel, a company dedicated to developing sustainable, climate-resilient hydropower, reports Amy Gunia for TIME. “The siblings hope that what they’re doing can help demonstrate a more sustainable approach to renewable energy – proving that companies shouldn’t have to choose between what’s good for the environment and what works economically,” writes Gunia.
Prof. Donald Sadoway is the recipient of the 2022 European Inventor Award for his work in liquid metal batteries, reports WBUR. “MIT says the battery could enable the long-term storage of renewable energy,” says WBUR.
Writing for The Conversation, John Reilly, co-director emeritus of the MIT Joint Program on the Science and Policy of Global Change, outlines a roadmap for how the U.S. can meet the Biden administration’s commitment to reducing carbon emissions 50% by 2030 below 2005 levels. “By exploiting declining costs of zero- and low-carbon energy sources in a more aggressive and focused way, the U.S. can meet its target within eight years,” writes Reilly, “all while substantially reducing its dependence on fossil fuels, including high-priced gasoline, and cutting back the air pollution, climate and health impacts resulting from their combustion.”
In a recent case study, Steven Gonzalez Monserrate PhD ’22 makes the case that the environmental cost of computer science, specifically computer cloud storage and data centers, are huge and will only continue to rise, reports Naomi Oreskes for Scientific American. “The cloud, he [Monserrate] contends, is a ‘carbonivore’: a single data center can use the same amount of electricity as 50,000 homes,” writes Oreskes. “The entire cloud has a greater carbon footprint than the entire airline industry.”
Researchers from MIT’s Plasma Science and Fusion Center (PSFC) and Commonwealth Fusion Systems (CFS) are working on making commercial nuclear fusion a reality, reports Juandre for Popular Mechanics. “CFS will build [the tokamak] SPARC and develop a commercial fusion product, while MIT PSFC will focus on its core mission of cutting-edge research and education,” says Prof. Dennis G. Whyte, director of the PSFC.
