GreenFire Energy and AltaRock Energy Partner on CO2G Renewable Geothermal Energy Project

Utah’s GreenFire Energy and AltaRock Energy of California have partnered on a technology sublicense agreement for a patent tied to using CO2 as the working fluid for geothermal energy plants.

According to GreenFire Energy, the CO2G™ method will produce renewable geothermal energy while also sequestering large volumes of CO2. The company aims to be the first in the world to commercialize the technology, and the sublicense agreement with AltaRock Energy provides it with the rights to its use throughout the St. Johns Dome area in Apache County, AZ, and Catron County, NM. GreenFire can also develop other sites as well.

Enhanced Oil Resources, Inc. entered into a joint venture with GreenFire in September 2009. It holds extensive CO2 leases at the dome and gave the renewable energy company exclusive access to CO2 within the dome for CO2G™ development.
