A report published last year by the Massachusetts Institute of Technology found that similar resources in the U.S. alone could generate up to 100,000 MW of power.
(Hot Fractured Rock)HFR mines Earth’s heat with wells up to 10 km deep into hot rock, connecting the wells to a fractured-rock region that has been stimulated to let water flow through it. This creates a heat exchanger that can produce large amounts of hot water or steam to run electric generators on the surface. It requires little fuel and emits no carbon dioxide. “This would be a breakthrough if they’re able to produce hot fluid at a sustained production flow rate that exceeds what has been achieved before,” says Tester. |
