About
Endurance Energy is a startup founded by SpaceX alumni that aims to harness terawatts of geothermal energy from deep in the ocean. The company's approach focuses on tapping into geologically active areas around the Ring of Fire, where tectonic plates spread apart, allowing hot magma to flow closer to the surface. Unlike traditional geothermal startups that drill thousands of feet into the Earth's crust, Endurance Energy plans to operate underwater, leveraging the oil and gas industry's experience with subsea operations.
