USA, California: New Interest in ECO2G™ Closed-Loop Geothermal Technology Project at Coso

J-Power and EPRI to work with GreenFire Energy Inc. on world's first demonstration of closed-loop geothermal power generation (News Release)

GreenFire Energy Inc. today announced that Electric Power Development Company, Ltd. (J-Power Company), a utility company in Japan, and the Electric Power Research Institute (EPRI) will participate in GreenFire’s demonstration of a closed-loop geothermal power generation system. J-Power Company will have project observation and information rights.

This project is the first implementation of GreenFire Energy Inc.’s innovative ECO2G™ closed-loop geothermal technology and will demonstrate the ability to produce power from a currently inactive well in the Coso, California geothermal field. The success of ECO2G could enable geothermal project owners to generate power from idle or marginal wells at low risk and attractive cost per megawatt-hour. This is significant because worldwide, about 20% of geothermal wells are unproductive for a variety of reasons.

The demonstration project will insert a coaxial closed-loop tube in an existing geothermal well that lacks sufficient pressure and permeability to generate power. Various fluids may be circulated to transfer heat to the surface where power potential will be carefully measured.
