Enhanced Geothermal Has A Flock Of Black Swans

Despite being mostly underground, enhanced geothermal systems (EGS) are having a moment in the sun. At its core, EGS involves drilling deep into hot, solid rock formations, artificially creating permeability by fracturing the rock, and circulating fluids to harness and produce power from the Earth’s heat. Unlike conventional geothermal, which … [continued]

Is Closed-Loop Geothermal The Future of Heat & Power, or Just a Niche Play?

Geothermal energy has long been the quiet workhorse of the clean energy sector—steady, reliable, and utterly unsexy compared to its flashier solar and wind counterparts. It’s also been stubbornly constrained by geography. Traditional geothermal requires naturally occurring underground reservoirs of hot water and steam, which means it’s only viable in … [continued]

Conventional Geothermal’s Untapped Potential: What’s Holding It Back?

Conventional geothermal electrical generation, where conditions are right, is an excellent form of renewable generation. It keeps chugging along day and night, offering firmed power with some of the highest capacity factors in the business and very low emissions per MWh. Yet, despite its many advantages, geothermal often gets left … [continued]
