In the United States (US), Turboden America LLC, a subsidiary of the technology provider for power generation and heat electrification, Turboden S.p.A., a Mitsubishi Heavy Industries Group company, has announced a three‑year framework agreement with Fervo Energy LLC, a next-generation geothermal development company, to supply Organic Rankine cycle (ORC) units for up to 35 GeoBlocks totalling 1,750 MW of carbon-free, dispatchable power capacity.
According to a statement, this agreement is expected to enable the optimal conversion of geothermal heat into baseload carbon‑free electricity and expand the US-based supply chain for Turboden’s proprietary ORC turbine design.
These strengthened capabilities are intended to help shorten lead times for current and future customers and provide geothermal energy developers with a more efficient path to meeting rising power demand.
This framework agreement also establishes delivery timelines that are expected to enable faster project execution and support supply chain resilience as Fervo scales.
Over the past two years, we have built a constructive strategic relationship with Fervo, and this framework agreement reflects a mutual commitment to continued and expanded collaboration. Geothermal energy will be essential in stabilizing a strained power grid with clean, firm energy, and Fervo has shown strong leadership in advancing the sector. With this announcement, we are prepared to scale delivery in the US market and add megawatts of new generation wherever and however they are required, said Paolo Bertuzzi, President of Turboden America and CEO of Turboden.
Builds on existing agreement
This commitment builds on Turboden’s prior agreement with Fervo to supply ORC units for three 50 MW GeoBlocks at Fervo’s enhanced geothermal development in Utah, Cape Station.
By establishing a multi‑year arrangement, Fervo has identified Turboden as a dependable supplier as it continues to scale and looks to rely on ORC technology as a core component of its projects.
Both companies plan to apply lessons learned across deployed units to continuously strengthen system performance. The companies are currently in the advanced commissioning stage of the Phase I project at Cape Station, a key milestone representing the first project to start within a large and strategic development pipeline, with startup expected later this year.
Expanding our work with Mitsubishi Heavy Industries is a key step in scaling geothermal to meet rising US power demand. By combining Turboden’s proven ORC technology with the global capabilities of Mitsubishi Heavy Industries, we are strengthening the supply chain needed to build geothermal at scale. This collaboration will play a central role as we continue to develop at Cape Station and beyond and bring reliable, 24/7 carbon-free energy to the grid, said Tim Latimer, CEO and co-founder of Fervo Energy.
As data center developers increasingly recognize geothermal energy as a viable baseload power solution, this agreement positions Turboden and Fervo to deliver fast‑tracked projects that address immediate, near‑term electricity demands.
Turboden’s ORC turbines, which convert heat into power without increasing fuel consumption, water use, or carbon dioxide (CO2) emissions, can also be used with gas turbines and a range of industrial processes that produce waste heat, unlocking additional capacity from existing infrastructure for utilities and other energy providers.
