Always-On Clean Power Puts Geothermal Back in Focus

New funding, IPO buzz, and corporate bets are pushing U.S. geothermal toward scale as demand grows for always-on clean electricity

26 Jan 2026

Geothermal energy in the US is attracting rising levels of capital as investors and large companies look for clean electricity that can run continuously, unlike wind and solar power.

A key focus is Fervo Energy, a fast-growing geothermal developer that has recently raised a large funding round and taken early steps towards a possible initial public offering. Analysts say a public listing would be an important test of whether advanced geothermal can scale into long-term infrastructure rather than remain a niche technology.

As Canary Media has reported, Fervo’s progress reflects broader interest in so-called firm clean power as electricity demand rises and concerns grow about grid reliability. Data centres, electrification and industrial demand are increasing pressure on power systems to deliver steady output.

Large technology companies are also playing a role. Google has invested in geothermal developers including Fervo as part of its strategy to secure round-the-clock clean energy for its operations. While details of long-term power contracts have not been disclosed, the investment signals growing confidence among corporate buyers that geothermal could provide dependable clean electricity.

Capital is also flowing into exploration, one of the sector’s most difficult and risky stages. Zanskar, a US-based geothermal company, has raised significant funding to apply modern data and imaging tools to the search for underground heat. According to The Wall Street Journal, the aim is to reduce drilling risk and speed up the identification of viable sites, potentially expanding the number of locations suitable for development.

The combination of project finance, corporate investment and new exploration techniques suggests an industry gaining credibility. However, obstacles remain. Geothermal projects often face long development timelines, high upfront costs and constraints linked to drilling capacity, permitting and grid connections.

Latitude Media has noted that as companies move closer to public markets, investors will look for evidence that projects can be repeated successfully across different locations, not just proven once.

Even so, momentum is building. With strong financial backing and growing demand for reliable clean power, geothermal is entering a phase where execution and scale will matter as much as technical innovation. If current investment trends persist, the sector could play a larger role in meeting the US economy’s rising electricity needs.
