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.

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...

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...
