In a groundbreaking initiative, Google has successfully launched a pioneering geothermal project in Nevada, in collaboration with startup Fervo. This venture employs cutting-edge technology to harness geothermal power, different from conventional methods, with a capacity to generate 3.5 MW. The electricity generated will support two of Google’s data centers outside Las Vegas and Reno, contributing to Google’s commitment to achieving carbon pollution-free electricity 24/7 by 2030.
This unique geothermal endeavor, conceived in 2021, deviates from typical geothermal plants by utilizing an existing geothermal field on the outskirts. Fervo’s innovative approach involves drilling two horizontal wells to pump water through hot rocks, creating steam on the surface. The closed-loop system not only reuses water but also incorporates fiber optic cables for real-time data monitoring, drawing inspiration from practices in the oil and gas industry.
Google’s investment in geothermal energy aligns with its strategy to diversify clean energy sources, viewing geothermal power as a crucial element in maintaining a consistent energy supply alongside intermittent sources like wind and solar. Besides the Nevada project, Google has partnered with Project InnerSpace to address geothermal development challenges globally, signaling a broader commitment to sustainable energy solutions.
While the specifics of future geothermal deployments for data centers remain undisclosed, Google’s move reflects a strategic shift to reduce the environmental impact of its energy-intensive data operations. This innovative geothermal project represents a significant leap forward, supported not only by Google but also by climate-focused entities such as Breakthrough Energy Ventures and the US Department of Energy.
