The company stands out by utilizing a closed-loop system filled with refrigerant in its boreholes, contrasting with traditional water-based methods used by other geothermal companies.
Leading the Series A funding round is Evok Innovations, along with investments from Active Impact Investments, Giga Investments, and others. Rodatherm faces competition from established players like Fervo Energy, Sage Geosystems, and XGS Energy.
Fervo Energy, a key competitor, has raised significant funding and is set to complete a 100-megawatt power plant in the near future. Rodatherm claims its refrigerant-based approach is 50% more efficient than traditional water-based systems.
The company’s patented closed-loop design eliminates the need for filters and minimizes water usage, offering potential efficiency gains. However, the approach may incur higher drilling and installation costs, which could be offset by its enhanced performance.
