GreenFire Energy has launched its first commercial next-gen geothermal demonstration project at The Geysers.
Early test results conducted at the site make for positive viewing, providing a positive foundation for the future of next-gen geothermal technology and its use in reservoirs of this type. The project’s early performance marks a major milestone in the efficiency of geothermal recovery, and highlights GreenFire’s ability to enhance output in mature fields using next-gen tech.
The installed system is now fully operational – with results showing higher-than-expected output temperatures in a stable closed-loop system. GreenFire Energy enhances heat recovery by leveraging natural convection and optimising saturation pressure within the reservoir, while maintaining a closed-loop flow. This approach allows for an efficient energy transfer with the potential to unlock more power from existing well structures, such as at The Geysers.
Two seven-day production tests have already been conducted, as well as a step-change test. An industry-standard duration steady-state test is nearly complete. These tests are designed to validate performance across multiple operating conditions and test the adaptability in other low-output wells to show the scalability of geothermal energy.
Rob Klenner, President of GreenFIre Energy, said, “This is a breakthrough – not just for our team, but for the future of geothermal. The ability to demonstrate a successful test at The Geysers is one of the biggest impacts the industry needs right now to scale new geothermal energy to the grid. We’re bringing real innovative solutions to the market. We’re delivering on our promises to show how next-gen technology can provide high-performance power with real commercial applications.”
The project is penned to be completed by June this year.
