Google's philanthropic arm,, said the investment would go toward so-called Enhanced Geothermal Systems. The technology circulates water through hot rocks in the ground, producing steam to power a turbine.

Conventional geothermal technology relies on finding naturally occurring pockets of steam and hot water in the ground.

Google's investment includes $6.25 million for AltaRock Energy Inc, $4 million for Potter Drilling Inc, and a $489,521 grant for Southern Methodist University's Geothermal Lab.
