Breakthrough in Supercritical Geothermal: 400C Energy's Milestone Paves the Way for Ultra-Low-Cost Clean Power By :  Robert Buluma In the rapidly advancing world of renewable energy, breakthroughs in geothermal technology stand out for their potential to deliver reliable, always-on power at costs that rival traditional fossil fuels. 400C Energy has just shared an exciting update: they have successfully completed rigorous testing of their 9.625-inch super-hot capable frac port equipped with integral flow control. This component withstood extreme cyclic conditions of 400°C and 15,000 psi frac differential, marking a major step forward for Enhanced Geothermal Systems (EGS) targeting supercritical resources. This achievement opens the door to generating electricity at a Levelized Cost of Energy (LCOE) below $50/MWh delivering ultra-low-cost, clean, baseload power that can compete directly with coal and natural gas while scaling quickly to utility-scale deployment. From Conventional G...

Exploration Risk: The Billion-Dollar Gamble Beneath Our Feet By:  Robert Buluma Image credit: Kane Watikson on LinkedIn  Geothermal energy is often described as the sleeping giant of the clean energy transition  constant, weather-independent, capable of delivering 24/7 baseload power without the intermittency that defines solar and wind. Yet despite this extraordinary promise, geothermal remains underdeveloped in most parts of the world. The reason is not lack of heat. It is not lack of demand. It is not even lack of technology and not even  FINANCE ,  Whilst many will throw that policy card, but Alphaxioms is already future proofing that .  The real barrier lies several kilometers beneath our feet  in uncertainty. Exploration risk is the defining challenge of geothermal energy. Unlike wind turbines that can measure wind speeds before construction, or solar farms that can predict output from sunlight data, geothermal developers must make multimillion-d...

In a landmark diplomatic moment that signals brighter prospects for Africa's clean energy future,  H.E. Mahmoud Ali Youssouf, Chairperson of the African Union Commission, formally received the Letters of Credentials from H.E. Ms. Olivia Owen, the newly appointed Ambassador of New Zealand to Ethiopia and the African Union, on February 4, 2026. This ceremony marks not just the beginning of a new ambassadorial tenure but a renewed surge of momentum in one of the most promising renewable energy partnerships on the continent: the AU–New Zealand geothermal cooperation. Amid Africa's urgent push to harness its vast geothermal resources—particularly along the East African Rift System—New Zealand's world-renowned expertise in geothermal development stands as a beacon of hope for sustainable, reliable, and affordable power. New Zealand, a global leader in geothermal energy, draws nearly 20% of its electricity from the Earth's natural heat. Its pioneering approaches to exploration...

Teverra and Earth Energy Explorers Ignite a Geothermal Revolution in Melilla: Spain’s Hidden Heat Awakens By:  Robert Buluma There are places on Earth where the future doesn’t arrive gently. It doesn’t knock politely. It doesn’t wait for permission. It erupts—quietly at first—through data, through drilling plans, through boardroom decisions that look ordinary to outsiders but feel like thunder to those who understand what is at stake. The Melilla Geothermal Project is one of those moments. A moment when a city perched on the edge of Europe, staring directly into the Mediterranean, begins to ask a question that could shake its energy destiny: What if the most powerful resource we need isn’t imported… but buried beneath us? This is the kind of question that rewrites history. And now, with Teverra partnering with Earth Energy Explorers (EEE), that question is no longer theoretical. It is becoming a plan—measured, engineered, and dangerously ambitious. Melilla is not just another Sp...

KenGen Launches International Tender for Essential Geothermal Wellhead Equipment Amid Kenya's Green Energy Push In a significant move to bolster its geothermal energy infrastructure, Kenya Electricity Generating Company PLC (KenGen) has issued an open international tender for the supply of specialized geothermal wellhead equipment. The tender, referenced as KGN-GDD-025-2026, focuses on expanding gate valves and adaptor flanges—critical components used in geothermal wellheads to manage high-pressure steam and ensure safe, efficient energy extraction. Released in January 2026, this procurement opportunity underscores KenGen's ongoing commitment to expanding Kenya's renewable energy capacity, particularly in the geothermal sector, which already accounts for a substantial portion of the country's power generation. Tender Details and Requirements The tender invites sealed bids from eligible candidates worldwide, emphasizing an open competitive process to attract qualified ...

Kenya’s geothermal sector stands at a pivotal crossroads in 2026, blending rapid expansion, legal scrutiny, fresh exploration, and bold affordability measures.  By: Robert Buluma Image: Trucks are flagged for Suswa Geothermal Block As Africa’s geothermal leader, Kenya harnesses the Rift Valley’s heat to deliver reliable, clean baseload power that stabilizes the grid amid fluctuating hydro and costly thermal backups. Today, the narrative unfolds across Menengai’s maturing projects, Suswa’s exciting new frontier, courtroom challenges, and policy reforms aimed at cheaper electricity for all. Menengai: From Vision to Reality with Turbulence The Menengai field in Nakuru County exemplifies Kenya’s innovative de-risking model. The Geothermal Development Company (GDC ) drills high-risk wells and confirms steam resources, then invites private independent power producers (IPPs) to build plants and purchase steam. This approach accelerates investment by removing the biggest uncertainty. Three...
