What is "enhanced" geothermal?
Instead of tapping into natural water-filled fractures in hot rock (which can only be found in volcanic areas), we create our own. Hot rock itself is ubiquitous if you go deep enough, and in large swaths of the world sufficient heat is accessible at under 6km depth - the deep end of the range oil and gas drillers regularly drill today.
Over the past five years, several companies have proven this next-generation approach – including our partner Sage Geosystems. The first enhanced geothermal plant in the US is operating commercially, with 100s of MWs under construction.
