Vulcan Energy Kicks Off Civil Works at Lionheart: Europe’s Flagship Geothermal + Lithium Plant Starts Rising in Landau Image: The vulcan Lionheart project in Landau, Upper Rhine Graben  Vulcan Energy Resources has started civil construction on its 30 MW Lionheart Geothermal Power Plant in Landau, Germany a milestone that turns engineering blueprints into concrete reality for one of Europe’s most ambitious integrated geothermal and direct lithium extraction (DLE) projects. The first concrete layers are down, foundations are being formed, and supporting infrastructure works are under way. For stakeholders across the clean‑energy and critical minerals value chains, Lionheart represents far more than a single power station: it’s a demonstration of industrial symbiosis, price resilience, and a pathway to decarbonized battery supply chains in Europe. Why Landau matters: location, geology, and industrial context Landau sits in the Upper Rhine Graben, a tectonic trough with a favorable geo...

Berlin’s Heating Transition Secures a Decade‑Defining Loan By: Robert Buluma In late April 2026, a quiet but decisive milestone was reached in Berlin’s energy landscape. Behind the scenes of the city’s vast district heating network—the largest in Western Europe—a consortium of nine banks finalised a syndicated loan of roughly one billion euros. The transaction, structured with a twenty‑year maturity and backed by a creative blend of public and private financing, effectively unlocks the financial foundation for Berlin’s most ambitious decarbonisation projects to date. This is not simply another infrastructure loan. It is a testament to how a city‑owned utility, a supportive state government, and a broad coalition of financial institutions can align around a common goal: transforming a fossil‑fuel‑dependent heating system into a climate‑neutral powerhouse by 2045. The deal also signals a new benchmark for energy infrastructure financing in Germany, potentially reshaping how similar proje...

Ruhr’s Geothermal Opening By:  Robert Buluma Germany’s largest geothermal exploration permit has been granted to a consortium planning to investigate the Ruhr region from Oberhausen to Hamm, and the significance goes far beyond a routine licensing milestone. The permit covers 1,640 square kilometers, making it the biggest geothermal exploration field in Germany to date, and it positions the Ruhr as a serious test case for urban geothermal heat at scale . This is a story about more than geology. It is about how a heavily industrialized region, with dense heat demand and established district-heating infrastructure, may be able to turn a deep subsurface resource into a practical climate strategy. If the exploration work succeeds, the project could reshape how Germany approaches low-carbon heating in cities and industrial corridors . 1 . The opening move The permit granted by the Arnsberg District Government opens the door for an extensive exploration phase under the banner “Erdwärme M...

Eavor Technologies achieved a significant breakthrough in December 2025 when its flagship closed‑loop geothermal project in Geretsried, Germany, began delivering electricity to the grid.  By:  Robert Buluma  The Canadian startup had completed the first of four planned underground loops and intended to start construction on the second loop in early 2026. That timeline has now been revised. The company encountered substantial engineering difficulties while drilling the initial wells, including borehole instability, slow penetration rates, equipment failures, and cement‑casing issues that allowed fluid to leak between parallel drilling rigs. Although Eavor resolved those problems, the setbacks increased both time and cost. As a result, the firm is now looking for new project partners and investors to help complete the next phase. The Geretsried site, located south of Munich, was chosen precisely because it is geologically challenging. Previous conventional geothermal attemp...

Powering the Future: Why the IGC Invest Geothermal Conference 2026 is a Must-Attend for Energy Leaders By: Robert Buluma   As the world races toward a net-zero future, one energy source is steadily moving from the sidelines to the center of the political and financial stage: Deep Geothermal Energy. While solar and wind have dominated the renewable conversation for decades, they leave a critical gap—baseload heat. Industrial processes and district heating networks cannot run on intermittent power alone. This is where geothermal steps in, offering a constant, inexhaustible, and local energy supply. However, the biggest hurdle has never been the technology itself; it has been the financing. Drilling deep into the earth is capital-intensive and carries geological risk. Bridging the gap between great geology and great returns requires a dedicated forum where capital meets engineering. That forum exists. From June 17 to 18, 2026, the IGC Invest Geothermal Conference returns to the Omnitu...

Erdwärme Franken: How N-ERGIE’s 2D Seismic Campaign Could Unlock a Geothermal Revolution Beneath Nürnberg and Fürth By: Robert Buluma   Germany’s Hidden Energy Treasure Beneath Bavaria Deep beneath the historic streets of Nürnberg, the industrial zones of Fürth, and the forests and municipalities surrounding them, an invisible energy reservoir may be waiting to transform the future of heating in northern Bavaria. While solar panels dominate rooftops and wind turbines reshape skylines across Europe, another renewable energy frontier is gaining momentum underground: geothermal energy. In a major step toward unlocking this potential, the “Erdwärme Franken” project led by is preparing to conduct a large-scale 2D seismic survey during the second half of 2026. The campaign will investigate underground geological formations across Nürnberg, Fürth, and neighboring districts to determine whether the region can support large-scale geothermal heat production. The announcement marks far ...
