Maybe it is because I am connected with Ryan Law on LinkedIn, but the number of posts about the success of the United Downs geothermal project was unstoppable for a…

Has enhanced geothermal been proven at scale?

Elliot Yearsley and Henk Kombrink

April 23, 2026

A few days ago, Fervo published production data from their geothermal Project Red in Nevada that answers some of the questions posed in previous GeoExpro articles. However, it also raises…
