Geothermal energy is gaining traction as a sustainable solution to power the energy-hungry AI data centers of major tech companies like Meta and Google. However, the path forward remains uncertain due to stiff competition from natural gas and the high upfront costs of geothermal projects.
The Rise of Geothermal for AI Energy Needs
Big Tech firms are partnering with geothermal startups to supply clean energy for their data centers. These partnerships are part of a broader push to meet the growing energy demands of AI technologies while accelerating investments in renewable energy.
Trey Lowe, Chief Technology Officer of Devon Energy, a shale gas producer and investor in geothermal startup Fervo Energy, highlights the potential: “We believe geothermal, along with abundant natural gas, can be part of the all-of-the-above energy mix we need to meet the demand.”
Geothermal energy offers advantages such as faster carbon-free electricity generation compared to nuclear energy and reliability over intermittent sources like wind and solar. Despite these benefits, challenges like high drilling costs and lengthy project approvals have tempered initial enthusiasm.
Investments and Industry Shifts
Since 2020, geothermal projects have attracted an estimated $700 million in funding. While startups like Sage Geosystems and Gradient Geothermal are pushing forward with innovative approaches, larger oil majors like Chevron and Exxon Mobil remain focused on natural gas, often coupled with carbon sequestration to lower emissions.
Sage Geosystems, for instance, recently raised $30 million and is planning a Series B funding round in January. Gradient Geothermal is leveraging existing oil and gas infrastructure to generate geothermal energy, a cost-effective strategy gaining interest among mid-sized energy firms.
Geothermal energy’s cost competitiveness is a key factor driving its appeal. The average levelized cost of electricity (LCOE) for geothermal projects in the U.S. stands at $64 per megawatt-hour (MWh), lower than combined-cycle natural gas ($77/MWh) and significantly cheaper than nuclear energy ($182/MWh).
The Texas Geothermal Boom
Texas is emerging as a hub for geothermal development, thanks to its abundant resources, streamlined permitting process, and regulatory certainty. Ten of the 22 geothermal startups launched in the U.S. between 2016 and 2022 are headquartered in Texas.
According to Matt Welch of the Texas Geothermal Energy Alliance, “Texas is becoming the ‘place to be’ for geothermal exploration and development across the board.”
Legislative and Market Support
Lower commodity prices are pushing shale companies to diversify revenue streams, with geothermal becoming a viable option. Bipartisan legislative interest, such as the recently passed CLEAN Act and HEATS Act, could further simplify the process of setting up geothermal projects in the U.S., boosting the sector’s growth.
Trey Lowe of Devon Energy notes that government incentives and the stability of geothermal investments are attracting more private capital: “A combination of a low decline asset with high certainty on pricing piques the interest of many investors.”
Challenges and Outlook
While geothermal energy has significant potential, its growth is clouded by competition from natural gas and the reluctance of major oil companies to commit fully. For geothermal to become a cornerstone of the energy mix, continued investment, innovation, and supportive policy frameworks will be essential.
