How Fervo is digging a deep financial hole

The problems started in 2023 with Project Red in Nevada. Fervo’s self-published paper described their small demonstration project as “commercial scale”. But Project Red was neither commercial (as in economically…

The end of Eavor?

A feat of engineering. That’s how the Eavor loops in Geretsried could be described. But that’s about it. When it comes to contributing to the energy transition, and the advance…

Why the Rittershoffen geothermal plant came to a halt

The ECOGI geothermal heat plant, located in Rittershoffen (France), has been exploiting geothermal energy from the naturally fractured reservoir of the Rhine Graben for 10 years, with an injection well…

Response to feedback from Mark McClure

Last week, we published the latest contribution from Elliot Yearsley, in which he discusses the lack of published well test data to support the claims made by Fervo about their…

The reservoir will always have its final say

With 500 Megawatts (MW) of plant capacity in construction for their flagship geothermal project at Cape Station, Utah, one might think that Fervo had already answered the questions on the…

No B without A

In oil and gas, production is influenced by market de­mand, but it remains relatively decoupled from end-use consumption – you produce hydrocarbons, sell them, and the relationship between producer and…

The low productivity of enhanced geothermal systems

Fervo Energy operate the world’s most well-funded Enhanced Geothermal Systems (EGS) project at Cape Station, Utah, and have published well test results from which the Productivity Index can be estimated.…
