From Steam to Soil:  KenGen and Kaishan Pioneer Kenya’s Green Ammonia Revolution By:  Robert Buluma Kenya is taking a bold step toward green industrialization. In a landmark collaboration, KenGen and Kaishan  Group have teamed up to develop Africa’s first large-scale geothermal-powered green ammonia and fertilizer plant at Olkaria in Naivasha. The project, valued at around $800 million , will utilize 165 MW of geothermal steam and power supplied by KenGen under a 30-year agreement. Kaishan’s subsidiary, Kaishan Terra Green Ammonia Limited , will construct and operate the facility, which is expected to produce over 100,000 tons of green ammonia annually—processed into fertilizer products like urea and ammonium nitrate. Transforming Kenya’s Energy and Agricultural Landscape This project marks a turning point for Kenya’s geothermal sector. It extends the value of geothermal energy beyond electricity generation, proving that steam can fuel not just turbines—but also ...

  Mazama Energy Ignites a New Era: The World’s Hottest Geothermal System Powers Toward a Carbon-Free Future By Robert Buluma , October 2025 In a quiet corner of Oregon’s Cascade Range, deep beneath the rugged volcanic landscape of Newberry, a new energy revolution is taking shape.  Mazama Energy — a startup incubated by Khosla Ventures and backed by Gates Frontier — has just achieved a technological milestone that could change the way we power the planet. At a staggering 629 °F (331 °C), Mazama’s newly completed Enhanced Geothermal System (EGS) is now the hottest ever recorded on Earth. And this is just the beginning. By 2026, the company expects to push those temperatures to 750 °F (400 °C) — unlocking enough energy to power gigawatts of clean electricity from this single site. 🔥 Cracking the Code of the Earth’s Heat For decades, geothermal energy has been the “quiet cousin” of renewables — clean, reliable, but limited to places where hot water naturally flows near the sur...

A New Chapter in Geothermal Diplomacy: Utah & New Zealand Seal Geothermal Pact By:  Robert Buluma In October 2025, a significant milestone was achieved when Spencer Cox, Governor of Utah, and Simon Watts, New Zealand’s Minister for Energy, signed a Letter of Intent in Auckland.

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...
