AI's energy hunger fuels geothermal startups but natgas rivalry clouds future
By Mrinalika Roy and Seher Dareen
Dec 19 (Reuters) -Geothermal energy startups are on the upswing with Big Tech companies looking to feed their power-intensive AI data centers, but long-term investments remain uncertain as oil majors double down on natural gas.
Meta META.O and Alphabet's GOOGL.O Google are among the tech companies partnering with startups proposing to produce geothermal electricity,to power their data centers.
Large data-center operators are also racing to meet the energy needs of artificial intelligence, acceleratinga range of clean technologies in the process.
"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," said Trey Lowe, chief technology officer at U.S. shale gas producer Devon Energy DVN.N, an investor ingeothermal startupFervo Energy.
Geothermal has been promoted as a faster way to generate carbon-free electricity than nuclear, and withoutthe intermittency of wind and solar. But the startups still face high upfront costs, particularly for drilling, and long project approvaltimes.
That has soured some of the initial enthusiasm, with limited investments so far- analysts estimate just over $700 million in financing has been contributed to overall geothermal projects since 2020.
Top shale oil producers Chevron CVX.N, Diamondback Energy FANG.O and Exxon Mobil XOM.N have also begun advocating for natural gas as the mainstay fuel for electric power, offering to work with utilities to couple their power plants with carbon sequestration projects that cut greenhouse emissions.
"In general, (there is) a lot more interest from smaller oil and gas producers as well as service companies ... we've talked to Chevron and Shell SHEL.L but the supermajors seem to be taking more of a wait-and-watch view," said Cindy Taff, CEO of Sage Geosystems, which is developing energy storage and geothermal baseload technologies deep in the earth.
Sage recently closed a $30 million fundraising led by U.S. shale gas producer Expand Energy EXE.O, formerly Chesapeake Energy, and plans to launch its Series B round in January.
In December, Colorado-based Gradient Geothermal - which generates geothermal energy using existing oil and gas infrastructure - announced it was providing Chord Energy CHRD.O services to help generate power at one of its oil and gas sites in North Dakota.
Gradient Chief Operating Officer Johanna Ostrumsaid most mid-size and smaller independent energy firmswere interested in geothermal energy for their own power needs, not to create electricity for resale.
Geothermal aims to compete on cost. The average levelized cost of electricity (LCOE) of the conventional geothermal projects in the U.S. is around$64 per megawatt-hour (MWh), which is competitive with other dispatchable energy sources such ascombined cycle gas, which is around $77/MWh on average, and nuclear, which is around $182/MWh, according to energy consultancy Rystad Energy.
Thanks to an improving investment landscape, more than 60 startupshave sprung to life in the last two years, said Bryant Jones, executive director of industry association Geothermal Rising.
"Texas is becoming the 'place to be' for geothermal exploration and development across the board," said Matt Welch at the Texas Geothermal Energy Alliance (TxGEA)."Much of this is due to an abundance of identified geothermal resources, 1-stop shopping permitting process and our regulatory certainty."
Ten of the 22 geothermal startups launched in the U.S. between 2016 and 2022 were headquartered in Texas, according to areport published last year.
The current lower commodity prices could also encourage more shale companies to diversify their revenue streams by tapping geothermal power.
The sector is receiving increased bipartisan interest as well. The CLEAN Act and HEATS Act recently passed the House and are awaiting Senate approval. If they become law, itwould make it easier to set up geothermal projects in the country.
"Government incentives and private investments are increasing...combination of a low decline asset with high certainty on pricing piques the interest of many investors," said Devon's Lowe.
