GreenFire Energy is reinventing the global geothermal industry. Tapping into the earth’s most abundant “always on” source of energy, GreenFire Energy, along with its distinguished research partners, continues to develop breakthrough carbon dioxide (CO2)-based geothermal energy technologies (CO2G™) engineered to accelerate the future of clean, sustainable energy.
Why CO2 Geothermal?
The most abundant and concentrated source of clean, renewable, baseload energy is not solar, wind, hydropower, or biomass. Rather, it is right underneath our feet in the form of geothermal heat. The challenge has long been how to harness that energy and bring it to the surface economically, while at the same time reducing project development timeframes and risk. The impediment to global geothermal energy exploitation is the very fluid that all other utility-scale facilities currently use: water. Conventional geothermal technologies are simply not applicable or economic outside a comparatively small number of sites. In order to help solve the global clean-energy problem, we must find ways to increase the use of this vast energy resource without the use of water, and to do so in a faster timeframe and in a more scalable, predictable manner with far less risk.
GreenFire Energy’s CO2G™ geothermal energy technologies accomplish this while presenting a solution to all three of our planet’s most critical problems: climate change, fresh water supply, and the global availability of affordable, clean energy. The earth is rich in geothermal heat and supercritical CO2 (SCO2) is a far superior fluid than water for collecting that heat and for driving highly efficient turbines. This fluid can be contained and controlled in the first-of-its-kind utility-scale, closed-loop design being developed by GreenFire Energy, an innovative technology called Convective Cycle CO2G™. GreenFire's use of SCO2, along with advanced, existing directional drilling and turbine technologies, are what make this game-changing design possible.
With vast global potential, Convective Cycle CO2G™ has superior economics rivaling those of natural gas, does not employ the use of traditional fracking or other well stimulation techniques, and does not depend upon clean-tech incentives. Instead of contributing to the problems of greenhouse gas emissions and water consumption, Convective Cycle CO2G™ employs the use of one of the primary culprits of our changing climate, carbon dioxide, as the geothermal working fluid, and does so with zero CO2 emissions and zero water consumption.
GreenFire Energy is a development-stage company. Our first commercial-scale demonstration projected is scheduled for completion in the Imperial Valley of California by Q2 2015.
