Enhanced geothermal has moved from pilot to project finance – Fervo's Cape Station energises in October 2026 – and the open question is now cost per MWh, not whether EGS works.

The thesis
Core thesis
Traditional geothermal is limited to volcanic regions. EGS uses horizontal drilling (borrowed from fracking) to access hot rock anywhere. Fervo Energy has moved from its 2023 Nevada pilot to commercial scale: Cape Station in Utah energises its first ~100MW in October 2026 on the way to a 500MW build-out by 2028, under a Google framework agreement for up to 3GW of geothermal through 2033. Fervo IPOd on Nasdaq in May 2026 (FRVO), raising roughly $2.2B. If EGS hits its cost targets, it is 24/7 clean baseload power – the holy grail for data centres. Drilling cost per MWh and induced-seismicity risk remain the open questions.
State of the art (2026)
Next-generation geothermal has crossed from pilot to project finance. Fervo Energy's Cape Station in Utah – the first commercial-scale EGS – has its initial 100MW on track to energise the grid in October 2026, with Baker Hughes and Turboden ORC turbines contracted toward a 500MW build-out by 2028 under a Google offtake. Closed-loop reached a milestone too: Eavor's Geretsried plant in Bavaria delivered first grid electricity in December 2025, proving the sealed-loop architecture without hydraulic stimulation. Ultra-deep remains pre-commercial – Quaise drilled 100m of granite with millimetre-wave gyrotrons in 2025, targeting a 2028 pilot. The live question is whether EGS levelised cost falls below roughly 60 dollars per MWh fast enough to win baseload, not whether it works.
