Ijen’s Blind Geothermal System vs. Zanskar’s AI-Discovered Resources: Two Models for Finding Hidden Heat The geothermal industry is entering a new phase in which the most valuable resources may no longer be the fields marked by obvious hot springs, geysers, fumaroles, or steaming ground. Increasingly, developers are targeting “blind” or hidden geothermal systems,reservoirs that lack clear surface expressions but can still contain the temperature, permeability, and fluid needed for commercial power generation. Two examples illustrate how different parts of the industry are approaching this challenge. In Indonesia, the Blawan-Ijen geothermal field in East Java was developed through geological interpretation, magnetotelluric imaging, conceptual modelling, and drilling. The project is now operating commercially, with its first phase delivering approximately 35 MW to the Java grid under a 30-year power purchase agreement. In the United States, Zanskar Geothermal & Minerals is using...
From Steam Engines to Servers: How a Historic Norwegian Factory Site is Reinventing Energy for the Future By: Robert Buluma In the heart of Telemark, Norway, where rivers once powered the industrial revolution, a quiet but profound transformation is taking place. The riverbanks that echoed with the clatter of heavy machinery are now the site of a different kind of innovation—one that merges the ancient stability of the Earth’s core with the high-tech hum of the digital age. The project is Nye Skotfoss Brug. It is a story about respecting the past while building a carbon-free future. It’s a story about taking waste—specifically, waste heat—and turning it into a community asset. And at its core, it’s a masterclass in circular energy economics. Let’s unpack how a team of forward-thinking developers, geothermal drilling experts, and energy system designers are turning a historic industrial site into a "futura district"—a blueprint for how we might heat our homes and power our l...
