Beyond the Hype: A Clear-Eyed Look at Geothermal’s Role in the Energy Transition - CleanTechnica

The article "Beyond the Hype: A Clear-Eyed Look at Geothermal’s Role in the Energy Transition" from CleanTechnica presents a comprehensive and nuanced examination of geothermal energy’s potential and challenges within the global energy transition. The author’s investigation evolved from initial curiosity into an extensive research project, culminating in a detailed report published by TFIE Strategy in September 2025. The report critically assesses geothermal technologies, balancing enthusiasm with realism by applying Bent Flyvbjerg’s framework on megaproject risks, which highlights the frequent cost overruns and delays in large-scale, first-of-a-kind projects. This approach helps differentiate between geothermal methods with scalable, modular potential—such as district heating and industrial heat pumps—and riskier, ambitious ventures like enhanced geothermal systems and ultra-deep drilling. The article underscores that while conventional geothermal power offers excellent low-carbon energy in select geographies, its global impact remains limited. Enhanced geothermal, often touted as imminent, faces historical setbacks including seismic risks and financial uncertainties,
