Amsterdam Strikes Geothermal Gold: Hot, Thick, Permeable Reservoir Confirmed

Breakthrough Beneath the Beach: Amsterdam Region Hits Geothermal Paydirt at Strandeiland By: Robert Buluma The Netherlands just took a giant leap toward fossil-free heating. On the artificial island of Strandeiland (part of Amsterdam’s fast-growing IJburg district), the SCAN exploration well has officially confirmed what the geothermal community has been hoping for: a thick, hot, and , most importantly permeable reservoir in the Slochteren Formation. Key numbers that matter:   Reservoir thickness: 152 meters   Bottom-hole temperature: 66 °C   Permeability: confirmed via successful production and injection tests   That’s not screaming-hot by Icelandic standards, but for direct-use district heating in one of Europe’s densest urban areas, 66 °C is more than enough to supply thousands of homes with clean, baseload heat – forever. Why This Well Changes Everything for the Netherlands The Dutch government launched the SCAN program (Seismic Campaign Nethe...

Zanskar’s Big Blind: First Blind Geothermal Discovery in 30 Years

Big Blind: The Geothermal Discovery That Changes Everything By: Robert Buluma Utah startup  Zanskar Geothermal quietly dropped one of the most important announcements in American energy in decades. They discovered and confirmed “Big Blind” ,the first completely blind, commercial-grade geothermal system found in the United States in over thirty years. Let that sink in. No hot springs.   No fumaroles.   No steaming ground.   No prior wells.   Zero surface expression whatsoever. Just desert, sagebrush, and – 7,000 feet below,  a reservoir hot enough and permeable enough to support gigawatt-scale power production. This isn’t incremental progress. This is a paradigm breaker. Why “Blind” Discoveries Matter So Much For the last 40 years, geothermal development in the U.S. has been geographically handcuffed. You could only build plants where nature advertised the resource on the surface – think Yellowstone, The Geysers, or Imperial Valley. Ever...
