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 ...
A Climate-Neutral Future for Hanover’s District Heating By: Robert Buluma The city of Hanover is taking a bold step toward a climate-friendly future with the implementation of an innovative geothermal energy project by Eavor in collaboration with enercity. This groundbreaking initiative aims to cover 15 to 20 percent of Hanover’s district heating needs using cutting-edge Eavor-Loop™ technology, significantly reducing reliance on coal-fired power plants and advancing the city's heat transition goals. The Hanover Geothermal Project: A Game Changer for District Heating Eavor is developing two Eavor-Loops™ in the Lahe district, each with a heat output of 15 MW. Once operational, this system will generate up to 250 million kilowatt hours of geothermal energy annually. This is equivalent to supplying heat for approximately 20,000 homes within the enercity supply area, ensuring a stable, renewable, and climate-neutral energy source. Replacing Coal with Sustainable Geothermal Energ...
