GreenFire Energy Closed-Loop Geothermal Demonstration at the Coso Geothermal Field

摘要

GreenFire Energy has demonstrated a downhole, closed-loop geothermal technology at the Coso Geothermal Field. In this demonstration, water and CO_2 were each circulated through a tube-in-tube heat exchanger placed 330 meters down the well, hung from the wellhead. At the same time, various production rates of geothermal steam were simultaneously produced. The primary goal of this demonstration was to verify GreenFire Energy's process modeling assumptions and to illustrate the power production potential of closed-loop geothermal technology.
