Google (TGW) - Google.org announced today that it will invest $10 million in Enhanced Geothermal Systems (EGS).
EGS differs from traditional geothermal in that it does not exploit existing wells of steam, but rather uses hot rocks far below the surface to heat water to generate steam.
Google invested in 3 different companies:
- AltaRock Energy
- Potter Drilling
- Southern Methodist University Geothermal Lab
