全球首次海底地热发电厂演示在距海面近一英里深的活跃海底火山附近进行。它产生了不到10秒的净正电力，但展示了利用另一种水下可再生能源的技术可行性。
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.
3吨原型发电厂的三周测试部署于9月在东北太平洋的轴海山进行。总部位于西雅图的初创企业Endurance Energy是该项目的发起方，旨在最终将海底地热能商业化，为太平洋岛国及其他寻求进口昂贵化石燃料替代方案的客户提供服务。
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. Endurance Energy, the Seattle-based startup behind the effort, aims to eventually commercialize subsea geothermal power for Pacific island nations and other customers looking for alternatives to importing expensive fossil fuels.
“深海为我们提供了无限的冷却海水，而海水的重量使系统和井保持加压状态，因此我们的电厂可以设计得紧凑，”Endurance Energy的创始人兼首席执行官Andrew Redd在给Ars的电子邮件中表示。
“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,” said Andrew Redd, founder and CEO of Endurance Energy, in an email to Ars.
