A new milestone has been achieved in the field of geothermal energy production in northern Nevada this week, as confirmed by a recent commercial pilot project.
Fervo Energy, a leading player in the sector, proudly announced the successful completion of the well test for its expansive commercial pilot initiative known as ‘Project Red’.
This achievement marks a significant step forward in advancing the utilization of cutting-edge geothermal power technology.
The favorable outcome of the well test serves as a validation of the practical viability of Fervo’s advanced drilling techniques, firmly establishing ‘Project Red’ as an unparalleled enhanced geothermal system in terms of productivity.
During the course of a 30-day well test, a benchmark often used in the geothermal industry, an impressive flowrate of 63 liters per second was achieved at a notably high temperature. This accomplishment enables the generation of 3.5 MW of electric power, shattering previous records for both flowrate and power output from an enhanced geothermal system.
Distinguished by its achievement, Fervo has become the pioneering entity in successfully drilling a horizontal well into thermal reservoirs to extract commercial geothermal energy. This accomplishment not only signifies a major leap forward in energy production but also effectively mitigates the risks associated with drilling operations.
“By applying drilling technology from the oil and gas industry, we have proven that we can produce 24/7 carbon-free energy resources in new geographies across the world,” Tim Latimer, Fervo Energy CEO and Co-Founder, shared.
“The incredible results are the product of many years of dedicated work and commitment from Fervo employees and industry partners, especially Google.”
In 2021, Fervo and Google forged a partnership to create the next-generation power plant. Their aim was to provide an uninterrupted, eco-friendly energy source for Google’s Cloud servers in Las Vegas. This initiative would substantially lessen the company’s dependence on fossil fuels.
As per an official statement, Fervo made notable strides by achieving lateral lengths of 3,250 feet, resulting in a temperature of 191 °C.
Fervo diligently implemented a protocol to mitigate induced seismicity, drawing from the best practices outlined by the U.S. Department of Energy (DOE). Remarkably, the entire project was executed without any untoward incidents. The data gathered during this pilot endeavor will accelerate the progress of geothermal deployment. Fervo’s upcoming horizontal well pair is projected to yield over twice the power output of the current pilot design.
Google’s Senior Director for Energy and Climate, Michael Terrell, also said, “Achieving our goal of operating on 24/7 carbon-free energy will require new sources of firm, clean power to complement variable renewables like wind and solar.”
Fervo says their results have shown that geothermal energy may be able to supply over 20% of U.S. power needs and compliment wind and solar in order to attain a fully decarbonized grid. “With Fervo’s breakthrough, no technological barriers to geothermal deployment remain.”
Jesse Jenkins, leader of the Zero-carbon Energy systems Research and Optimization (ZERO) lab at Princeton University, said, “Fervo’s successful commercial pilot takes next-generation geothermal technology from the realm of models into the real world and starts us on a path to unlock geothermal’s full potential.”
Presently operational in 26 nations, geothermal technology generates electricity by circulating cold water into the Earth’s depths. There, the water is naturally heated by the planet’s internal temperature. Upon being brought back to the surface, this water does not release carbon or any detrimental pollutants.
During the ongoing summer season, Fervo initiated construction on its inaugural greenfield project in the southwestern region of Utah. This site is located next to the Department of Energy’s Frontier Observatory for Research in Geothermal Energy (FORGE). The proceeds and insights garnered from Fervo’s undertaking in Utah will be channeled into the establishment of additional projects in previously unexplored geographical locations.
