Endurance Energy

Modular subsea geothermal power

Endurance Energy is building the world's first modular subsea geothermal power plants, converting the vast thermal resources beneath the ocean into gigawatts of baseload power. Its founding team includes veterans from SpaceX, Helion, Blue Origin and Apple, and the company has already completed multiple deep-ocean deployments to subsea volcanoes, with a long-term demonstration project launching this autumn. By combining modular design, manufacturing scale, efficient drilling and the latent cooling available on the seafloor, it is pioneering an energy category that outperforms traditional sources on environmental impact, deployment speed and cost.
