BRIN and Geo Dipa Pioneer Modular Wellhead Technology for Small-Scale Geothermal Power Revolution By: Robert Buluma Opening Perspective: A Quiet Revolution at the Wellhead Across Indonesia’s volcanic arc, geothermal energy has long been viewed through the lens of massive power stations—multi-well, multi-megawatt installations requiring years of development and heavy capital investment. But a quieter transformation is emerging. Instead of waiting years for large-scale geothermal plants, engineers and researchers are now asking a radical question: What if geothermal power could begin at the wellhead itself—small, fast, modular, and locally distributed? This is exactly the direction being taken by Indonesia’s national research agency BRIN in collaboration with state geothermal developer Geo Dipa Energi . Their joint effort to develop modular wellhead technology for small-scale geothermal power plants represents one of the most important shifts in geothermal development strategy in...

Unlocking the Brussels Sandstone Member How Integrated Reservoir Science Is Rewriting Geothermal Potential in Southwest Netherlands By: Robert Buluma Pull Quote “The real issue was not the geology — it was that the geology was being interpreted through the wrong lens.” For decades, the Netherlands was defined by one thing underground: natural gas. The Groningen field didn’t just fuel an economy — it shaped it. But as production winds down due to seismicity concerns and policy reversal, a quiet shift is underway beneath the surface of Dutch energy planning. The next chapter is not deeper gas. It is heat. And one of the most interesting candidates sits in an unlikely place: the Brussels Sandstone Member (BSM) — a shallow, heterogeneous Eocene reservoir in southwest Netherlands. Not a high-enthalpy volcanic system. Not a turbine-spinning giant like Olkaria or Menengai. But in a country built on district heating, industrial heat demand, and greenhouse agriculture, even moderate-t...

Star Energy’s Lampung Drilling Campaign: Indonesia’s Next Geothermal Frontier Awakens The ground beneath Lampung has waited long enough. For years, the Sekincau geothermal prospect in southern Sumatra existed as a promise—mapped, studied, debated, and cautiously anticipated. Beneath its surface lies a force that has powered civilizations in silence: geothermal energy. Now, that silence is about to be broken. In 2026, is preparing to initiate what could become one of the most consequential geothermal drilling campaigns in Indonesia’s recent history. The move signals more than just another exploration program—it marks a decisive step into Indonesia’s next geothermal frontier. This is not just drilling. This is ignition. The Sekincau Prospect: From Geological Promise to Strategic Reality Located in Lampung Province, the Sekincau geothermal field represents a classic greenfield opportunity—untapped, uncertain, and filled with both risk and transformative potential. Unlike brownfield expan...

Geothermal Power Meets Corporate Demand: A New Era of Offsite PPA Decarbonization In a world racing toward decarbonization, one truth is becoming increasingly clear: renewable energy must not only be clean—it must also be reliable. While solar and wind have dominated the conversation for years, their intermittency continues to challenge industries that rely on uninterrupted power. Now, a groundbreaking development from Japan is redefining what corporate renewable energy procurement can look like, and at the center of it lies geothermal power. In April 2026, Daiwa Can Company, in partnership with Kyuden Mirai Energy and Tokyo Electric Power Company Energy Partner, launched an innovative offsite corporate Power Purchase Agreement (PPA) powered by geothermal energy. This initiative is more than just a contract—it represents a paradigm shift in how industries can secure stable, low-carbon electricity while mitigating operational risks. The Rising Importance of Corporate PPAs Corporate ...

Geothermal Power Meets Data Centers in Strategic Shift By: Robert Buluma The global energy landscape is undergoing a profound transformation, and at the heart of this shift lies an unexpected but powerful convergence: geothermal energy and digital infrastructure . In a move that signals both ambition and foresight, Pertamina Geothermal Energy (PGEO) is preparing to expand beyond its traditional role as a power producer and enter the rapidly growing data center industry . This is not just another diversification strategy. It is a calculated leap into the future—one that aligns renewable energy with the insatiable demand for digital services. The implications are far-reaching, not only for Indonesia but for the global energy-tech nexus. A Bold Step Beyond Electricity For decades, geothermal companies have largely focused on one thing: generating electricity. PGEO , a subsidiary of Indonesia’s energy giant Pertamina, has been no exception. With a growing portfolio of geothermal assets and...

Engie’s Geothermal Ambitions in Réunion Island: A Turning Point for Energy Independence in Volcanic Territories By: Robert Buluma In a world increasingly defined by the urgency of energy transition, remote island territories stand at the frontline of both vulnerability and opportunity. The recent move by to secure a geothermal exploration permit in marks more than just another project milestone—it signals a potential transformation in how isolated regions harness their natural resources to break free from fossil fuel dependency. This development, centered in the Cafres-Palmistes highlands, is not merely about drilling wells or building a power plant. It is about unlocking the immense geothermal promise hidden beneath volcanic landscapes, navigating environmental sensitivities, and setting a precedent for sustainable energy in island economies worldwide. A Strategic Foothold in Volcanic Terrain Réunion Island, located east of Madagascar in the Indian Ocean, is a geological marvel...
