Ars Technica reports that the three-week test deployment of the 3-ton prototype power plant took place at the Axial Seamount in the northeast Pacific Ocean in September.

The world’s first demonstration of a subsea geothermal power plant has taken place near an active underwater volcano almost a mile below the ocean surface. It generated less than 10 seconds of net-positive electricity but showed the technical feasibility of tapping another form of renewable energy underwater.

This environment story centres on the United States. Names and organisations mentioned in the coverage include Pacific Ocean, Axial Seamount and Endurance Energy.
