Green Therma deploys demonstration of closed-loop geothermal in Groß Schönebeck, Germany Green Therma has deployed its closed-loop geothermal demonstration at the Groß Schönebeck research site in Germany, and the project is now moving from installation into operation. The system is intended to test the company’s Heat4Ever/DualVac concept under real geothermal conditions at depths of more than 3 kilometers.  Green Therma deploys closed-loop geothermal demonstration in Groß Schönebeck, Germany Green Therma has reached an important milestone in the development of closed-loop geothermal technology with the deployment of its demonstration project at the Groß Schönebeck research site in Germany. The company says the system is now circulating water through a single-well closed-loop configuration, bringing geothermal heat to the surface from more than 3 kilometers underground.  The project is being carried out at the GFZ Helmholtz Centre for Geosciences’ geothermal research facility,...

JKP Beogradske elektrane , has launched a new tender for the third phase of scientific studies into the geothermal potential of underground water resources at sites within its heating-plant and boiler-house network.  The procurement is for services, uses an open procedure, and carries reference number 160 ОУ/26. The submission deadline is 19 October 2026 at 10:30, and the tender status is listed as published.  This procurement is significant because it shows that the city’s geothermal program is moving beyond preliminary exploration and into a more detailed assessment phase. The tender documentation indicates that the work is intended to support the evaluation of geothermal resources for district heating use, which aligns with broader efforts to reduce reliance on fossil fuels in urban heating systems.  What the Tender Covers The procurement title is “Phase 3 scientific study of the geothermal potential of underground water resources in the territory of heating plants and...

Close Collaboration on Geothermal Heating Supply Launched in Potsdam Potsdam is taking a major step toward a cleaner and more resilient heating future. Energie und Wasser Potsdam GmbH (EWP) and the GFZ Helmholtz Centre for Geosciences have signed a project agreement that launches a four-year cooperation program to develop additional geothermal sites in the Brandenburg capital. The partnership is designed to systematically unlock the city’s hydrothermal geothermal potential and integrate it into the municipal heating network over the long term. This collaboration matters because the heat transition is no longer a theoretical goal. It is becoming a practical infrastructure challenge for cities across Germany. As older energy systems approach the end of their technical life, municipalities need solutions that are local, dependable, and affordable. Deep geothermal energy offers exactly that kind of pathway, and Potsdam is now positioning itself as one of the cities prepared to make it work...

Geothermal Energy in the Netherlands: A Deep Research Brief Executive Summary The Netherlands has become one of Europe’s most advanced geothermal heat markets, moving from early pilot projects into commercial scale-up. In 2024, 23 operational installations produced 7.49 PJ of geothermal energy, and broader sector reporting indicates more than 30 operational installations are now active across the country . The market is led by direct heat for greenhouse horticulture, district heating, and selected industrial uses, while electricity generation remains a longer-term prospect because the country’s most accessible geothermal resources are generally better suited to heat than power . The Dutch case matters because it shows how geothermal grows when geology, demand, data, and policy align. National planning has long set ambitious expansion goals, including a pathway from roughly 3.5 PJ in 2018 toward 50 PJ by 2030 and more than 200 PJ by 2050 . More recent analysis is more cautious about the...

Green Therma and the Future of Geothermal Scale in Europe By: Robert Buluma Geothermal energy has long been one of the most intriguing renewable resources in the global clean energy mix. It is steady, local, and available around the clock, unlike solar and wind, which depend on weather and daylight. Yet despite these advantages, geothermal has often remained a niche part of the energy landscape. The reason is not a lack of potential, but a combination of technical complexity, high upfront drilling costs, site-specific geology, and the challenge of scaling projects in a repeatable way. That is why companies promising a new generation of geothermal systems tend to attract attention. Green Therma is one of those companies. Its message is bold: geothermal technology for scale, potentially up to 25,000 wells in Europe. That is a major claim, and it deserves careful attention. If such a model works, it could change how Europe thinks about district heating, industrial heat, and energy securi...

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...
