Underwater Volcanoes Are Geothermal Energy’s Next Frontier

A Seattle startup is seeking to revolutionize geothermal energy by tapping into undersea volcanoes. In September, a 100-kilowatt geothermal generator will be deployed to the seafloor off Oregon’s coast, where a hydrothermal vent emits temperatures of up to 750 degrees Fahrenheit. The pilot project – the fifth of its kind – will continue to test the viability of turning that heat into commercially competitive, round-the-clock, and totally emissions-free electricity. The team behind the project at Endurance Energy believes...
