Key Takeaways
- Endurance Energy successfully tested a subsea geothermal power plant near an underwater volcano.
- The test, conducted in September, generated electricity from the heat of the volcano.
- The company aims to commercialize this technology for island nations and other customers.
Endurance Energy, a Seattle-based startup, has demonstrated the technical feasibility of generating electricity from underwater volcanoes through a subsea geothermal power plant. The test, conducted in September, utilized the heat from the Axial Seamount, an active underwater volcano located in the northeast Pacific Ocean, nearly a mile below the ocean surface.
The prototype power plant, weighing 3 tons, was deployed for a three-week period. It successfully generated less than 10 seconds of net-positive electricity, proving the concept's viability.
Andrew Redd, founder and CEO of Endurance Energy, explained, 'The deep ocean provides us with unlimited cold seawater for cooling, and its weight keeps the system and the well pressurized, allowing our plants to be compact.'
This technology could offer a sustainable alternative to importing expensive fossil fuels, particularly for Pacific island nations and other remote areas.
Endurance Energy's goal is to commercialize subsea geothermal power, leveraging the unique advantages of the deep ocean environment.
The company believes that this technology can significantly reduce the reliance on imported fuels, providing a reliable and renewable energy source for remote communities.
While the current test was brief, it marks a significant step towards the widespread adoption of subsea geothermal power as a viable renewable energy solution.
The success of this proof-of-concept test paves the way for further development and deployment of subsea geothermal power plants in the future.
The deep ocean gives us unlimited cold seawater for cooling, and its weight keeps the system and the well pressurized, so our plants can be compact.
