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 ...
Breakthrough in Taiwan’s Deep Geothermal Energy: Academia Sinica and CPC Corporation Drill Nearly 4,000 Meters in Yilan and Find High-Potential Reservoir Published: December 10, 2025 By: Robert Buluma In a historic milestone for Taiwan’s renewable energy journey, Academia Sinica (Central Research Academy) and Taiwan’s state-owned CPC Corporation have successfully completed the island’s first-ever “deep geothermal exploratory well” in Yuanshan Township, Yilan County. The well reached a depth of nearly 4,000 meters, recorded a bottom-hole temperature close to 150 °C, and confirmed the existence of an upwelling heat source beneath the northern Yilan Plain. Researchers are now calling it a “high-potential geothermal reservoir” that could become a cornerstone of Taiwan’s green energy transition. From Anxiety to Excitement: The Temperature Surprise Dr. Ji-Chen Lee (李建成), principal investigator of the “Taiwan Geothermal Research and Technology Development Project” and researcher a...
