GreenFire Energy designs, develops, and builds “GreenLoop” ™ geothermal projects to capture heat energy from hot dry rock where conventional hydrothermal technology cannot operate but where 98% of geothermal resources reside. The key innovations are closed-loop wells and proprietary thermodynamic models for optimized well production. In contrast to hydrothermal technology that requires heat, water and subsurface permeability, closed-loop system require only sufficient heat. This dramatically reduces project and drilling risk, compresses time to revenue, and uses a much higher percentage of a given resource. GreenLoop can be used to rehabilitate existing wells or for large new projects.

GreenLoop technology is the product of years of research conducted in concert with geothermal operators, the U.S. Department of Energy, several national laboratories, major universities. In May 2019, GreenFire Energy successfully demonstrated GreenLoop technology at the Coso geothermal operatio...

GreenLoop technology is the product of years of research conducted in concert with geothermal operators, the U.S. Department of Energy, several national laboratories, major universities. In May 2019, GreenFire Energy successfully demonstrated GreenLoop technology at the Coso geothermal operations in southern California. The project was funded in part by the California Energy Commission, Shell Oil, Coso Operating Company, the Electric Power Research Institute, and J-POWER.

GreenFire Energy offers two types of GreenLoop solutions. The “Well Retrofit” solution revitalizes existing but failed hydrothermal wells. Well Retrofits comprise a flexible system of components and processes that can be employed in a variety of configurations to optimize geothermal power production in a wide spectrum of well conditions. The Well Retrofit deployment is fast and takes approximately 6 months. The solution is cost competitive generating 1 to 4 MWe with a simple payback of about 2 years. GreenFire offers well retrofits to geothermal field operators on a “design- build” basis.

GreenFire’s “Field Scale” solution incorporates advanced drilling and completion technologies that revolutionized the oil industry to develop large new geothermal projects. Field Scale projects feature long closed-loop wells in various configurations which permits much greater well density and resulting heat extraction. Low-density hydrothermal technology on average uses only about 10% of the available heat. High density drilling also substantially re¬duces the cost per well and permits economies of scale in site development, power purchase agreements, and transmission lines. GreenFire’s Field Scale technology will be used to develop GreenFire projects but may also be licensed to geothermal development companies.

Recommendations

GreenFire Energy's innovative closed-loop, renewable geothermal power technologies for new and retrofit applications have the potential to provide secure, sustainable, 24/7 carbon free electric power with lower lifecycle environmental impacts than solar and wind.
