Strataphy and Baker Hughes Forge Strategic Alliance to Accelerate Geothermal Cooling and Saudi Arabia’s Energy Transition By: Robert Buluma Saudi Arabia’s journey toward a low-carbon, diversified energy future has taken a decisive step forward with the signing of a strategic Memorandum of Understanding (MoU) between Strataphy and global energy technology leader Baker Hughes. Announced in Khobar in December 2025, the partnership signals a powerful convergence of deep-tech innovation and industrial-scale execution,aimed squarely at accelerating geothermal cooling and advancing the Kingdom’s broader energy transition agenda. At a time when cooling demand is surging across the Middle East,driven by rapid urbanization, giga-projects, data centers, and industrial expansion,this collaboration positions geothermal energy not merely as an alternative, but as a cornerstone technology for sustainable infrastructure in Saudi Arabia. A Landmark Agreement with Strategic Implications Under the MoU,...

A 400-Year-Old Tudor Mansion Just Chose Next-Gen Geothermal  And It Changes Everything Posted by  Robert Buluma | December 11, 2025 Deep in the rolling countryside of Suffolk, England, stands Kentwell Hall ,a moated, red-brick Tudor masterpiece built in 1563, complete with octagonal guard towers, a 16th-century long gallery, and gardens that have hosted queens. For centuries it has been heated (if you can call it that) by a wheezing, century-old oil boiler that gulps thousands of litres of heating oil every winter yet still leaves the 400-year-old rooms chilly and the fuel bills astronomical. That is about to change , dramatically, invisibly, and permanently. This week it was announced that Kentwell Hall has selected CeraPhi Energy , a British deep-geothermal pioneer, to carry out a world-first feasibility study and, if successful, install a closed-loop deep geothermal heating system that will make the entire estate net-zero with almost zero visible impact on the Grade I list...

Exciting PhD Opportunity at Utrecht University : Unravelling Clogging Mechanisms in Porous and Fractured Rocks (Deadline: 14 December 2025) Published on  December 2025 By: Robert Buluma Are you a curious MSc graduate in Earth Sciences, Geology, Physics, or a related field who wants to work on cutting-edge research that directly supports the energy transition? Then this fully funded PhD position at Utrecht University (The Netherlands) might be exactly what you’re looking for! The Project – Why it matters Many of tomorrow’s energy solutions  geothermal energy, CO₂ storage, underground hydrogen storage , depend on injecting and extracting large volumes of fluids into the subsurface. A major risk that can kill these projects is clogging: pores and fractures gradually get blocked by particles, precipitates, or biomass, reducing permeability and sometimes stopping flow altogether. Although individual clogging mechanisms are reasonably well studied, we still lack a good understanding...

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...

First Utility-Owned Geothermal Network Set to Double with DOE Grant , A Bipartisan Clean Energy Win By: Robert Buluma In a political climate where clean energy funding is under siege, geothermal is emerging as the unexpected survivor. Just days ago, the U.S. Department of Energy greenlit an $8.6 million grant to expand the nation's pioneering utility-led geothermal heating and cooling network in Framingham, Massachusetts. This move, finalized under the Trump administration, signals that geothermal – reliable, efficient, and domestic – might just be the renewable technology that transcends partisan divides. The Framingham Pilot: A Groundbreaking Start Launched in 2024 by Eversource Energy , the Framingham project marked a U.S. first: a utility-owned networked geothermal system serving an entire neighborhood. Spanning residential homes, a school, a firehouse, and low-income housing, the initial phase taps into stable underground temperatures around 55°F via dozens of boreholes drill...

Exclusive interview with Exergy : discover the new Gemini dual-flow radial outflow turbine, the first single-unit ORC solution for 30–60 MW geothermal projects, offering up to 30 % lower costs and 99 % availability. By:  Robert Buluma .   An interview with  Luca Pozzoni -  Deputy CEO | Group CFO - Exergy International and the Exergy Team 1. Can you walk us through the key design innovations in your new Gemini turbine and how it differs from previous models? The major innovation of the Gemini turbine lies in the dual-flow configuration: unlike conventional radial outflow turbines which are equipped with a single bladed overhung rotor disk, the Gemini features a double-side bladed rotor disk mounted in a between-bearing configuration. This enables the efficient processing of significantly larger volumes of fluid, leading to higher power output having basically two radial outflow turbines in a single machine with enhanced operational stability and simplified mainte...

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...

Alberta launches $35-million challenge to reinvent drilling for the next 50 years   By  Robert Buluma | December 3, 2025   EDMONTON – The days of drilling straight down and hoping for the best are long gone. Today, operators in Western Canada routinely steer multi-kilometre horizontal wells with pinpoint accuracy from a single surface location. Tomorrow’s wells, however, could be guided entirely by artificial intelligence, powered by low-emission rigs, and used to unlock everything from geothermal heat to critical minerals and permanent CO₂ storage. That future just got a $35-million boost. Emissions Reduction Alberta (ERA ) officially opened applications this week for the Drilling Technology Challenge, a funding program designed to bridge the “valley of death” that too often kills promising subsurface innovations before they ever reach the field. “Many great ideas never make it past the prototype stage because the cost and risk of real-world testing are simply...

Iceland's Geothermal Renaissance: Government Bets Big on Low-Enthalpy and Innovative Uses By: Robert Buluma Iceland has long been the poster child for geothermal energy. With legendary high-temperature fields powering everything from the famous Blue Lagoon to nearly 100% of the country’s electricity and district heating, most people assumed the geothermal story was already written. Apparently not. In a move that has the global geothermal community buzzing, the Icelandic government has just announced a massive ISK 600 million (roughly €4 million / $4.4 million USD) grant program specifically designed to kick-start innovative geothermal projects, with the state covering up to one-third of total project costs. What makes this announcement truly exciting isn’t the money itself (Iceland has funded geothermal before), but the deliberate shift in focus: low-enthalpy resources and non-traditional applications. Why This Matters  The Low-Enthalpy Revolution For decades, Iceland’s geothermal ...

DeepStor : Turning a Former Oil Field into a Giant Underground Heat Battery at KIT Campus North Published by  Robert Buluma : | November 2025 Imagine storing the surplus summer heat deep underground and bringing it back up in winter to warm an entire research campus  without burning any gas or emitting CO₂. That is exactly what the DeepStor research infrastructure at Karlsruhe Institute of Technology (KIT) Campus North is setting out to prove.  From black gold to green heat The Upper Rhine Graben, one of Europe’s classic oil provinces, still hides dozens of depleted hydrocarbon reservoirs beneath its surface. Instead of abandoning them, the DeepStor team wants to repurpose one of these former oil fields as a high-temperature seasonal heat storage  essentially a gigantic geothermal battery. Hot water (up to 130–150 °C) would be injected in summer when solar thermal collectors, waste heat from industry or even waste incineration plants produce more heat than needed. ...
