Subsea geothermal for energy abundance
The grid problem
Power availability
is the world's
greatest need
From island nations, to industrial sites, to hyperscale data centers, quality of life and technological progress are directly correlated with the availability of low cost power.

From island nations, to industrial sites, to hyperscale data centers, quality of life and technological progress are directly correlated with the availability of low cost power.
In 2022, the industrial sector accounted for 33% of total U.S. energy consumption. Nearly 80% of this industrial energy usage comes from fossil fuel and coal.

OUR BREAKTHROUGH
Subsea geothermal offers limitless renewable energy
Under the sea, where tectonic plates spread and new crust forms, volcanic activity provides ideal conditions to produce electricity from Earth’s internal heat.
