Turboden ,  Fervo and the Future of Geothermal: 180 MW of Gen-2 ORC Plants for Cape Station, Utah By:  Robert Buluma October 2, 2025    In a landmark move for clean energy and geothermal power, Turboden America LLC   the U.S. arm of Turboden S.p.A. (a Mitsubishi Heavy Industries group company)  has been selected to supply 180 MW of Gen-2 Organic Rankine Cycle (ORC) power plants for Fervo Energy’s Cape Station geothermal project in Utah. A New Milestone in Geothermal Deployment This award relates to Phase II of the Cape Station development, following  Turboden’s earlier participation in Phase I. Under Phase II, Turboden will provide three ORC units , each with a gross output of 60 MWe, summing to 180 MWe. Once installed and operational (targeted by 2028), these Gen-2 units will bring the total ORC capacity on site to 300 MWe , making Cape Station one of the largest geothermal installations globally. The earlier Phase I installation, invol...

Vulcan Energy  Secures $196 Million Deal for Geothermal Power and Lithium Production in Germany By:  Robert Buluma In a major leap for Europe’s clean energy transition, Vulcan Energy  Resources has signed a landmark $196 million (€110 million) supply contract with European firms Turboden and ROM Technik .

Jakarta, September 2025   In a move that could change how Indonesia leverages its enormous geothermal endowment, PT Pertamina Geothermal Energy Tbk  (PGE) and PT  Toyota Motor Manufacturing Indonesia (TMMIN) signed a joint declaration to develop a green hydrogen ecosystem in Indonesia.  By:  Robert Buluma The announcement  made at the 11th Indonesia International Geothermal Convention & Exhibition (IIGCE) in Jakarta  signals an ambition to turn geothermal heat into a strategic feedstock for low-carbon fuels and industrial feedstocks, not just electricity. Why this matters Indonesia sits on some of the world’s richest geothermal resources. Traditionally those resources have been used to generate baseload electricity; PGE’s partnership with Toyota broadens the conversation: use geothermal power and heat to produce green hydrogen, then convert that hydrogen into transport fuels, ammonia, methanol, or industrial hydrogen for heavy industry. That pivot...

Geothermal energy is often called the “quiet backbone” of the clean energy transition. To understand the science, challenges, and innovations driving this sector, we spoke with a seasoned geothermal reservoir engineer with experience spanning the Andes, Nevada, Utah, and volcanic fields worldwide. Here’s what they shared. By:  Robert Buluma 1. What sparked your passion for geothermal reservoir engineering, and did you ever imagine yourself working in some of the world’s most challenging geothermal fields? My passion was sparked during my early career in the petroleum industry, specifically in reservoirs. I was fascinated by the subsurface—how fluids move, how heat and pressure interact but it wasn’t until I worked on projects in Peru that I realized geothermal offered the chance to apply my skills to clean energy. I never imagined I would later work on Enhanced Geothermal Systems (EGS) projects in Nevada and Utah or Andean volcanic fields, where the geology is as unforgiving as it ...

XGS Energy  Achieves 3,000-Hour Milestone for Water-Independent Geothermal System By : Robert Buluma HOUSTON, Sept 30, 2025 – In a groundbreaking achievement for the geothermal sector, XGS Energy has announced the successful 3,000-hour operation of its water-independent geothermal system at commercial scale. This milestone not only validates the system’s commercial economics but also positions XGS as the first company to demonstrate such technology under real-world, commercial conditions. A New Era in Geothermal Innovation The operations took place at the Coso Geothermal Field in California’s Western Mojave Desert, a site owned by Atlantica Sustainable Infrastructure and operated by Coso Operating Company. XGS Energy  revitalized a well that had been idle for over two decades, installing its proprietary closed-loop geothermal system enhanced by Thermal Reach Enhancement (TRE) technology. Flow testing delivered a record performance, maintaining a sustained temperature differenc...

CKW and Localnet AG are investigating geothermal energy potential in the Burgdorf region to provide continuous, climate-friendly heat and power. Discover how the project is progressing, what steps are planned, and what it could mean for sustainable energy in Switzerland. Why Geothermal Energy Matters CKW  and  Local Net AG have launched preliminary studies for a possible geothermal project in the Burgdorf region. The goal is to assess whether geothermal energy can be used to produce heat and electricity in a way that is climate-friendly and independent of weather conditions. Unlike solar, wind, and hydropower that depend on daily or seasonal patterns, geothermal can provide continuous, reliable energy an important factor in Switzerland’s push toward climate neutrality. Scope of the Initial Studies In the coming months,  CKW (a subsidiary of the Axpo Group) and  Local Net Ag will: Analyze publicly available underground and geological data. Evaluate the poten...

Cornish Lithium  Secures £35M in Equity Funding  A Milestone for UK Critical Minerals By:  Robert Buluma In a major boost for the UK’s domestic battery supply ambitions,  Cornish Lithium has announced that it has secured £35 million in new equity funding. This capital raise is intended to propel its key projects closer to construction and commercial stages, marking a pivotal moment in the firm’s trajectory.

Mount Erciyes: A Hidden Geothermal Treasure Beneath Cappadocia By: Robert Buluma Beneath the snow-capped slopes of Mount Erciyes , central Turkey’s highest peak, lies more than just volcanic history  it harbors the promise of geothermal energy . A new study published in the Journal of Volcanology and Geothermal Research has mapped the subsurface of Erciyes using three-dimensional magnetotelluric (MT) imaging , revealing zones of high electrical conductivity that point to heat, fluids, and possible magma bodies deep underground. Cracking the Code Beneath the Mountain Researchers led by S.B. Tank used advanced MT techniques to peer beneath Erciyes and its surroundings. Their results uncovered conductivity anomalies   regions where electricity flows more easily due to the presence of saline fluids, hot water, or partially molten rock . For geothermal experts, these anomalies are gold. They act as subsurface fingerprints of geothermal reservoirs , highlighting where heat ...

Gulf Energy  Takes Over Tullow Oil’s Turkana Fields – Oil Drilling to Overlap a Geothermal Hotspot By:  Robert Buluma In a landmark energy shift for Kenya, British explorer Tullow Oil  has officially exited the country after 14 years , selling its Turkana operations to Gulf Energy  in a deal worth Ksh.16 billion (USD 120 million). The transition marks the end of  Tullow's chapter in Kenya and the beginning of a new phase that could reshape not only oil production but geothermal exploration as well. The takeover grants  Gulf Energy full control of the Turkana oil project , situated in a geologically active zone that also happens to host significant geothermal potential. Beneath Turkana’s arid landscapes, volcanic systems create natural heat reservoirs turning the region into a rare frontier where oil and geothermal energy converge. Tullow Oil  first entered Kenya in 2010, striking the Ngamia-1 discovery well in 2012, which ignited hopes of the countr...
