A team of researchers from MIT and the National Renewable Energy Laboratory successfully reached a 30% jump in thermophotovoltaic (TPV) efficiency, reports Robert F. Service for Science. “[TPV] is a semiconductor structure that concerts photons emitted from a heat source to electricity, just as a solar cell transforms sunlight into power,” explains Service.
MIT announced five projects "targeting the world's toughest climate riddles" that were selected following a rigorous two-year competition, reports Benjamin Kail for Boston Business Journal. “Climate Grand Challenges represents a whole-of-MIT drive to develop game-changing advances to confront the escalating climate crisis, in time to make a difference,” says President L. Rafael Reif.
Prof. Jessika Trancik speaks with Wall Street Journal reporter Nidhi Subbaraman about the dramatic drops in costs to manufacture and sell renewable technologies. Subbaraman notes that Trancik’s research shows that “the steep drop in solar and lithium-ion battery technology was enabled by market expansion policies as well as investment in research and development by governments and the private sector.”
A study conducted by Prof. Susan Solomon and her colleagues has found that unlike CFCs, smoke destroys the ozone in a more roundabout way, creating concerns due to the impact of the Australian bushfires of 2019-2020, reports Krystal Vasquez for EOS. “Because of the sheer scale of the event [the Australian bushfires] massive amounts of smoke penetrated the normally pristine upper stratosphere,” writes Vasquez.
Research engineer Paul Woskov speaks with Bloomberg Radio host Tom Moroney and Joe Shortsleeve about his work with Quaise Energy in developing a laser to drill holes into the earth. “There is a lot of heat contained within our planet. The amount of heat that is present, if tapped, could supply all of our energy needs for several million years,” says Woskov.
Researchers from MIT and MIT spinoff Quaise Energy speak with Boston Globe reporter David Abel about their work developing a new way to drill as deep as 12 miles into the Earth’s crust, using a special laser, which could provide a way to tap the geothermal energy in the rocks. “This is game-changing,” Woskov said. “We now have the potential to exploit an energy source that . . . could unleash the virtually limitless supply of energy beneath our feet.”
Boston Globe reporter Hiawatha Bray spotlights how a number of MIT spinoffs are working on changing the world’s energy-storage systems. “Behind these companies are key technological advances in chemistry and materials, many of them pioneered at the Massachusetts Institute of Technology,” writes Bray. “These breakthroughs have put battery startups at the forefront of the region’s climate-tech sector.”
Prof. Susan Solomon speaks with Wall Street Journal reporter Nidhi Subbaraman about her research and another recent study that provides evidence wildfire smoke poses a threat to the ozone layer. “It’s fair to say that, at least for a few months, these wildfires canceled out the last decade of all the efforts that we put in over the Montreal Protocol,” says Solomon. “I think there’s every reason to believe this is going to happen more often, and it’s going to act to slow down the recovery of the ozone depletion.”
Prof. Yet-Ming Chiang and his colleagues are developing a new, inexpensive iron-air battery technology that could provide multi-day storage for renewable energy by 2024 through their startup Form Energy, reports Anuradha Varanasi for Popular Science. Chiang explains that “the battery can deliver clean electricity for 100 hours at a price of only $20 kilowatts per hour – a bargain compared to lithium-ion batteries, which cost up to $200/kWh,” writes Varanasi.
Smoke from Australian wildfires in 2019 and 2020 appears to have contributed to the breakdown of the ozone layer, according to a new study by MIT scientists, reports Sharon Udasin for The Hill. “The new study establishes the first direct link between wildfire smoke and ozone depletion,” writes Udasin.
Daily Beast reporter Miriam Fauzia writes that a new study by MIT scientists finds that smoke particles from wildfires are slowing the recovery of the ozone layer.
BBC News correspondent Helen Briggs writes that MIT scientists have found that increasing wildfires may slow the recovery of the ozone layer. "All the hard work that the world went to to reduce chlorofluorocarbons (ozone-depleting chemicals once used in aerosol sprays) is not paying off as well in the areas that experience extreme wildfires," explains Prof. Susan Solomon. "The best hope would be that we reduce global warming gases also and stop increasing the wildfires, but that's obviously more difficult."
A new study by MIT scientists finds that smoke emitted into the atmosphere from Australian wildfires in 2019 and 2020 resulted in depletion of the ozone layer, reports Donna Lu for The Guardian. The findings suggest “rising fire intensity and frequency due to the climate crisis may slow the recovery of the ozone layer.”
E&E News reporter Sara Schonhardt reporter speaks with Michael Mehling, deputy director of the MIT Center for Energy and Environmental Policy Research, about how Russia’s invasion of Ukraine will impact the transition to cleaner energy in Europe. “I think it will lend further support to the not only environmental imperative of decarbonization, but also the strategic imperative of becoming energy independent with locally available renewables,” says Mehling.
Wired reporter Gregory Barber spotlights Prof. Desirée Plata’s work developing a new process for removing methane emissions using zeolite. Plata’s team is currently working on converting their system to a filter that air can be pushed through. “Plata wants to install the filters in places where methane is concentrated, but there’s not enough of it to burn,” Barber explains.
