Enhanced Geothermal
One concrete 2026 milestone: the first commercial-scale project set to deliver grid power.
Still an emerging category overall, but with a specific, dated milestone behind the leader: the first-ever commercial-scale enhanced geothermal project delivering grid power, targeted for October 2026.
Standings
Fervo Energy’s Cape Station in Utah is on track to become the first commercial-scale enhanced geothermal project to deliver grid power, targeted for October 2026 — backed by a $2.2B IPO in May 2026 and a Google framework deal for up to 3 GW through 2033.
Decades of mature, at-scale conventional and hybrid geothermal deployment across both power and district heating — the deepest institutional expertise of any country, now extending into research like the Krafla Magma Testbed drilling directly into magma in 2026.

How this ranking was determined
Only two leaders are listed, deliberately — no clear third country has comparable evidence yet in this still-thin field. That gap will likely close within a year or two; forcing a bronze now would mean inventing one.
