ChatGPT generated panoramic aerial view of Dronninglund’s solar thermal fields and insulated water pit storage, set beautifully against a winter backdrop
Having grown up in Canada’s north and spent far too many winters trudging through snowy downtown streets in Toronto, Ottawa, and Edmonton, I know firsthand just how brutal Canadian winters can be—and how urgently our cities need practical, scalable, low-carbon heating solutions. Even if you haven’t spent months navigating icy … [continued]
ChatGPT generated panoramic sparrow's eye view of a serene neighborhood heated by ground-source geothermal
When China starts scaling a technology at massive levels, the rest of the world should take notice. That’s not a geopolitical statement, it’s a thermodynamic and logistical one. China doesn’t mess around when it comes to heat, power, and infrastructure. And in the case of ground-source heat pumps used for … [continued]
ChatGPT generated panoramic image of a book with "Fossil Marketing" written on it, and "Geothermal" stamped across it
One of the things I’ve found amusing while researching this series on geothermal is how much the sector’s rhetoric mirrors the natural gas and nuclear industry’s. It’s not the flex they think it is, highlighting clearly that they are the poor cousins trying to compare favorably to the affluent and … [continued]
Deep drilling isn’t optional for enhanced geothermal systems (EGS), it’s the whole point. To understand why, think of the Earth’s crust as a hot soup. Near the surface, it’s merely lukewarm, barely useful beyond warming your house if you’re lucky. Go deeper, however, and temperatures rise rapidly, roughly 25 to … [continued]
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]
ChatGPT generated panoramic aerial view of a large geothermal power plant in Indonesia, showcasing steam rising from production wells within a lush volcanic landscape
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]
ChatGPT generated panoramic image capturing the geothermal plant amidst Iceland's mystical volcanic landscape
For several years now, people have been asking me about enhanced or deep geothermal energy. I’ve fielded questions from readers, investors, policymakers, and fellow analysts, and it’s clear there’s renewed enthusiasm for geothermal’s potential role in our energy future. It’s time I delved into this topic comprehensively, and this article … [continued]
Borobotics, a Swiss startup company, has created a compact boring machine that is compact enough to be used almost anywhere.
Framingham, Massachusetts is the first city in the US where a gas utility is now offering geothermal services to its customers.
New lithium mines will plug a gaping hole in the US EV battery supply chain until more sustainable, alternative sources emerge.
