This Kumamoto Geothermal power plant is an addition to Japans Geothermal power planets as we had earlier on highglighted on the one in Appi

Recently the world has been keen on Geothermal power plant however Japans Geothermal base is yet to be fully unlocked given that only 0.03 % of geothermal is being utilized even when the country is located strategicaly in the Pacific ring of a Fire , a Geothermal hotspot theres an obvious need of companies to boster up this resource With the right mode of approach.

The silence of a clean energy industry that desperately needs success stories… but is still learning how to measure them. In this one-on-one interview, we explore what it really takes to build a geothermal-driven clean energy company in today’s market, from strategic decisions and funding discipline to leadership, ethics, and the painful sacrifices behind growth. 1)  Vision & Strategy: “Speed Is Everything” Q:   Teverra  has grown rapidly, but co...

Geothermal Power Play: Well Engineering Partners Takes Over Operations as Sproule ERCE Sharpens Advisory Focus

The geothermal energy sector is heating up literally and figuratively and a recent strategic move is set to accelerate progress in sustainable energy production. By: Robert Buluma Effective January 1, 2026, Well Engineering Partners (WEP) acquired the operational and production-focused geothermal activities from Sproule ERC (formerly associated with Veegeo). This acquisition marks a smart realignment of strengths in the booming geothermal market, where clean, reliable baseload energy is increasingly vital for the global energy transition. Imagine harnessing the Earth's natural heat to power homes, industries, and cities without the intermittency of solar or wind. Geothermal energy does exactly that, providing constant output from deep underground reservoirs. But turning that potential into reality requires specialized expertise from initial resource assessment to long-term well maintenance. That's where this deal shines: it allows each company to double down on what they do b...

The Billion-Dollar Gamble Beneath Our Feet: Why Geothermal Exploration Is the Industry’s Greatest Risk

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...
