In conjunction with this year's GRC Annual Meeting a fieldtrip has been announced to Coso Geothermal Operations and GreenFire Energy’s Closed-Loop Demonstration Plant, September 18-19, 2019.

Geothermal Resources Council has announced a fieldtrip to Coso Geothermal Operations and GreenFire Energy’s Closed-Loop Demonstration Plant, September 18-19, 2019. The fieldtrip is part of the GRC Annual Meeting taking place September 15-18, 2019 in Palm Springs, California.

The fieldtrip offers a rare opportunity to explore operations, volcanic geology, and hydrothermal features of the Coso geothermal field located at the China Lake Naval Air Warfare Station (NAWS), California. The Coso Geothermal Facility is known for its large and very hot geothermal resource. It has been producing power continuously since 1987. The tour will include views of Quaternary rhyolite domes and flows, Sierran basement rocks (geothermal resource host), a short-lived mercury mine, sinter terraces and fumaroles, plus the Coso well field, power blocks, and the central control room.

The tour features a visit to GreenFire Energy‘s experimental project demonstrating closed-loop geothermal power production technology. GreenFire Energy’s project has been tested using both water and supercritical CO2 as working fluids and is designed to demonstrate usage in hot dry rock resources and to retrofit unproductive conventional geothermal wells to regain productivity. The Coso and GreenFire Energy project has been primarily funded by the California Energy Commission with additional support from Shell Oil, the Electric Power Research Institute, J-POWER, and a variety of key suppliers, all of whom will have representatives on site for the tour.
