Geothermal Startup Fervo Energy Reaches Key Milestone in Clean Energy Transition
Introduction
Geothermal startup Fervo Energy recently achieved a significant technical milestone, advancing the role of geothermal energy in the transition to clean energy.
By drilling deep wells and pumping water into them, Fervo harnesses the heat from the Earth’s core. The heated water is then brought back to the surface, where a turbine converts it into electricity.
In a 30-day test at its commercial pilot plant in Nevada, Fervo successfully drilled down to 7,700 feet and then horizontally to another 3,250 feet, reaching internal temperatures of approximately 375 degrees Fahrenheit. This test demonstrated the conditions necessary to generate 3.5 megawatts of electricity, enough to power around 2,625 homes simultaneously.
Fervo is now embarking on the construction of a 400-megawatt project, expected to be operational by 2028, which would provide power to approximately 300,000 homes.
Experts believe that Fervo’s achievement marks a significant step towards unlocking the full potential of geothermal energy.
Leveraging Oil and Gas Drilling Technology
Fervo’s success is attributed to its innovative use of drilling technology derived from the oil and gas industry. By utilizing hydraulic fracturing techniques, Fervo can create reservoirs deep underground, enabling the development of geothermal resources in various locations worldwide.
Tim Latimer, CEO of Fervo Energy, recognized the potential of oil and gas drilling advancements for geothermal energy. His idea faced initial resistance but found support within Stanford University’s geothermal program, where he co-wrote a paper on the subject in 2017. This paper served as the foundation for Fervo Energy, which has since secured over $200 million in investments.
Fervo’s Partnership with Google and Future Plans
Google, known for its commitment to carbon-free energy, has partnered with Fervo to develop a geothermal power plant. Geothermal energy, unlike wind and solar, provides a constant and reliable source of carbon-free power.
The partnership involves Google applying its expertise in artificial intelligence and machine learning to enhance Fervo’s efficiency. In return, Fervo contributes clean energy to Nevada’s grid, where Google is a major clean energy customer.
The U.S. Department of Energy is also driving the development of enhanced geothermal systems through its “Enhanced Geothermal Shot” initiative. The goal is to reduce the cost of enhanced geothermal energy by 90% to $45 per megawatt hour by 2035, potentially providing clean energy to millions of homes.
While Fervo still faces challenges in scaling up geothermal energy, experts recognize its recent achievement as a significant milestone in the industry. Enhanced geothermal systems, like the ones developed by Fervo, have the potential to serve as long-duration energy storage, complementing wind and solar power in a decarbonized grid.
