GreenFire Energy will be exploring the deployment of modular next-gen geothermal facilities to power the data centers of Iron Mountain in the United States.
GreenFire Energy and Iron Mountain Data Centers have announced a collaboration to identify and evaluate potential sites in the United States for the development of next-generation geothermal projects to support data center operations.
Under the collaboration, GreenFire Energy will aim to deploy 25 to 50 MW geothermal modules that will be co-located with energy-intensive infrastructure such as data centers. This will help supply reliable and climate-neutral power supply to the data centers while reducing reliance on stressed local grids. It also provide a pathway to hyperscale data infrastructure while supporting the growth of next-generation geothermal technologies.
The initiative also aligns with GreenFire Energy’s focus on behind-the-meter, co-located geothermal development. This modular approach is more agile, allowing for the faster deployment of geothermal power projects with lower early-stage risk and capital requirements. More details on the flexible and scalable approach of GreenFire Energy is available in our interview with with Rob Klenner, President of GreenFire Energy.
Iron Mountain Data Centers is a global IT services company that has deployed data centers in more than 30 sites across Europe, Asia, and the USA. As the demand for data and AI services increases, data center growth needs to be coupled with sustainable, secure, and reliable power. With this venture into potential geothermal deployment, the company is leveraging on increasing AI demand as a catalyst for the growth of geothermal energy.
Data centers are increasingly becoming large-scale off-takers for geothermal power. Google has already signed 265 MWs in PPA for geothermal power to support their data center operations in Nevada – 115 MW with Fervo Energy and 150 MW with Ormat Technologies – while also being involved in geothermal development in Taiwan and Australia. Meta has also shown similar interest with co-development agreements signed with Sage Geosystems and XGS Energy.
