The Retrofit Revolution: How GreenFire Energy Is Unlocking Geothermal Power Without Drilling a Single New Well By: Robert Buluma While much of the geothermal energy sector has been focused on breakthrough drilling techniques—deeper wells, hotter reservoirs, and complex engineered systems—a quieter revolution has been unfolding in the background. Instead of chasing entirely new subsurface frontiers, one company has chosen a radically simpler question: What if the answer was already in the ground? GreenFire Energy is advancing a retrofit-first geothermal strategy that targets one of the most overlooked opportunities in the global energy transition: existing wells that are underperforming, depleted, or completely abandoned. Rather than drilling new holes into the Earth, the company is reusing the infrastructure that already exists—turning stranded assets into continuous sources of clean, baseload electricity. This approach is not just technically elegant. It may also be one of ...
Exciting news for the advanced nuclear sector as the US-based Centrus Energy Corporation has completed construction on a cutting-edge uranium enrichment plant in Piketon, Ohio. This state-of-the-art facility features a cascade of 16 advanced centrifuges and is set to revolutionize the production of high-assay low-enriched uranium (HALEU) by the end of 2023. The HALEU cascade at Piketon (Image: Centrus) With the support of the US Department of Energy, Centrus received USD150 million in funding to bring this project to life. The cascade and its associated systems have undergone rigorous testing and the completion of fissile material storage and Nuclear Regulatory Commission (NRC) operational readiness reviews are the final steps before production can commence. Piketon is the only production facility in the US that has been licensed by the NRC for HALEU production, making this a major milestone in the advanced nuclear industry. The HALEU produced here will be enriched to between 5% and 20...
