Driving the UK Toward Net Zero: Chris Sladen on Geothermal’s Untapped Potential

Alphaxioms, we talked to Chris Sladen about his involvement in geothermal both in the UK, and globally By:  Robert Buluma Chris, please begin by explaining a little about yourself, and why you have a passion for geothermal? I have spent over 45 years involved in energy. Following undergraduate studies in geology at Southampton University, and a PhD in sedimentology at Reading University, I joined the energy sector in Aberdeen in 1980. It was a fascinating era when it seemed like at least one giant oil & gas field was discovered offshore every month; the wealth creation for the UK was gigantic. I got to see so much geology and rocks - my true passion. I moved to China in late 1983; not today’s China, this was over 40 years ago, a country closed for decades and embarking on an open-door policy, in part to bring both investment and technology. I became very interested in energy trends, energy politics, and new geography created by changing politics leading to opportunities for ene...

Unlocking Geothermal Power: Subsurface Secrets of Mount Erciyes Revealed”

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 ...
