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 ...
Cowi to Spearhead 100MW Geothermal Power Plant Expansion in Iceland: A Leap Toward Renewable Innovation By: Robert Buluma In a major stride toward sustainable energy development, Cowi , a leading engineering firm, has secured the design contract for the expansion of the Hellisheidi Geothermal Power Plant in Iceland. This ambitious project, driven by ON Power , will see the plant's capacity increase by 100MW, further solidifying Iceland's commitment to harnessing its geothermal potential. The Hellisheidi plant, located just 18km from Reykjavik, serves as a cornerstone for Iceland's energy landscape, providing both electricity and hot water for domestic heating. With the ongoing expansion, the plant’s heating output will rise from 200MW to 300MW, ensuring more homes and businesses in Reykjavik benefit from geothermal energy. A Legacy of Excellence Cowi's involvement in the Hellisheidi project dates back to its early phases, when the firm, formerly known as Mannvit ...
