Endurance Energy’s Prototype Subsea Geothermal Well Produced ~2 kW for 8.7 Seconds After First-Ever Mile-Deep Seafloor Drilling

Endurance Energy drilled the world’s first subsea geothermal well about 300 miles off Oregon and briefly produced ~2 kW for 8.7 seconds from a prototype that the company had hoped would run a 100 kW generator for a year; the team says the mission proved seafloor drilling is possible despite technical setbacks and tough offshore conditions.
