Mazama Energy is a geothermal startup targeting deeper and hotter rock. It has drilled past 10,000 feet in 15 days on its way to about 15,000 feet deep. At those depths, the company can access 400˚C heat, which at high pressures turns water into a “supercritical” fluid that’s neither fully liquid nor fully gas — a state that lets it absorb far more energy than ordinary steam. Mazama says that will allow each well to produce up to 10 times more power than traditional geothermal technologies. Company's first site in Oregon is capable of producing 10 gigawatts of electricity.
