TDK Corporation has announced that its corporate venture-capital subsidiary, TDK Ventures, Inc., is investing in geothermal power-generation company Rodatherm’s USD 38M Series A funding round. The strategic investment will help advance Rodatherm’s innovative closed-loop advanced geothermal system (AGS) technology, which promises to deliver affordable, long term, sustainable, and baseload energy.
Operating in stealth since 2022, and with operations in both Calgary, Alberta, Canada and Salt Lake City, Utah, Rodatherm has developed a fully cased, pressurized, closed-loop geothermal system optimized for sedimentary basins to enable both conductive and convective heat transfer into the working fluid. Rodatherm’s working fluid is fully isolated and used directly in a power-generating turbine, achieving 50% higher efficiency than water-based binary-cycle geothermal systems with exceptionally low operating and maintenance costs. Rodatherm’s advanced geothermal system is expected to achieve competitive levelized costs of energy with firm power, including fossil fuels, at early project scale and is designed to have an operating life lasting decades.
