About Rodatherm

Rodatherm Energy Corporation is a privately held geothermal power generation company founded in 2021 by CEO Curtis Cook. Operating from Calgary, Alberta, and Salt Lake City, Utah, the firm focuses on the Great Basin region in the Western United States. Having operated in stealth mode since 2022, the company recently announced a $38 million Series A funding round led by TDK Ventures and Evok Innovations. This capital is intended to fund the construction of its first pilot system in Utah.

Rodatherm is developing a patented Advanced Geothermal System (AGS), a closed-loop technology that uses refrigerants as the working fluid instead of water. This fully cased, pressurized system is designed for use in sedimentary basins, enabling both conductive and convective heat transfer. The isolated working fluid is used to directly drive a power-generating turbine, a method projected to be up to 50% more efficient than conventional water-based binary-cycle geothermal systems. Key advantages of this approach include a significant reduction in water usage, the elimination of filtration needs, and lower operating and maintenance costs, as the closed system prevents contamination. The technology is composed of individually mature and commercialized components, with its novelty lying in their patented combination into a modular system.

The company's business model centers on the development, construction, and operation of these geothermal power plants, providing baseload and dispatchable electricity. Rodatherm aims to deliver power at a levelized cost competitive with fossil fuels, even at an early scale. The firm plans to sell the electricity generated from its initial 1.8-megawatt Utah pilot plant to Utah Associated Municipal Power Systems, with the goal of having it operational by the end of 2026.
