New Google geothermal electricity project could be a milestone for clean energy

Google announced Tuesday that an advanced geothermal project has begun pumping carbon-free electricity onto the Nevada electric grid to feed Google data centers there

An advanced geothermal project has begun pumping carbon-free electricity onto the Nevada grid to power Google data centers there, Google announced Tuesday.

Getting electrons onto the grid for the first time is a milestone many new energy companies never reach, said Tim Latimer, CEO and co-founder of Google's geothermal partner in the project, Houston-based Fervo Energy.

“I think it will be big and it will continue to vault geothermal into a lot more prominence than it has been,” Latimer said in an interview.

The International Energy Agency has long projected geothermal could be a serious solution to climate change. It said in a 2011 roadmap document that geothermal could reach some 3.5% of global electricity generation annually by 2050, avoiding almost 800 megatonnes of carbon dioxide emissions per year.

But that potential has been mostly unrealized up until now. Today's announcement could mark a turning point.

Fervo is using this first pilot to launch other projects that will deliver far more carbon-free electricity to the grid. It’s currently completing initial drilling in southwest Utah for a 400-megawatt project.

Google and Fervo Energy started working together in 2021 to develop next-generation geothermal power. Now that the site near Winnemucca, Nevada is operating commercially, it's sending about 3.5 megawatts to the grid. There are three wells there.

The data centers require more electricity than that, so Google signed other agreements for solar and storage too. It has two sites in Nevada, one near Las Vegas and the other near Reno. Michael
