ARPA-E bets on materials that can survive superhot geothermal wells

Runs the SUPERHOT program and selected the eight projects

On November 12, the Department of Energy's Advanced Research Projects Agency-Energy (ARPA-E) selected eight teams to share up to $30 million for one problem: building wells that survive rock hotter than 375 °C and under more than 22 megapascals of pressure. Commercial geothermal equipment tops out near 220 °C. Above that, steel casing, Portland cement and off-the-shelf electronics tend to fail.
