The small town of Bad Bevensen, nestled in the serene Lüneburger Heide region of northern Germany, has long been known for its healing thermal springs and tranquil spa culture.

But beneath its peaceful surface lies a powerful, silent force: the Earth's own heat, waiting to be tapped. Now, in 2026, a bold geothermal project is reigniting hope for a sustainable, carbon-free future—and it's set to transform the town's energy landscape by 2029.
Imagine a future where homes, hospitals, the historic Kurhaus, and the Rathaus are warmed not by imported gas or fluctuating fossil fuels, but by clean, reliable heat drawn from over three kilometers underground. Temperatures reaching 128°C at around 3,300 meters make this possible. This isn't science fiction—it's the ambitious vision now being driven by Berlin-based NULLCOZWEI GmbH, a company stepping in to rescue and accelerate a project that once seemed stalled.
From Setback to Second Chance
The story began years earlier when Bad Bevensen explored geothermal energy to heat its district network. The town even established a dedicated company for it. But high costs, long timelines, and municipal risks led the city council to pause the initiative in early 2025. Many feared it was the end.
Enter NULLCOZWEI. In October 2025, the Berlin innovators signed an agreement with the town to take full responsibility. They revived the core concept with smart tweaks to the development plan and risk profile. Crucially, federal funding programs now cover the roughly 10 million euros in drilling costs completely—removing one of the biggest barriers.
As Managing Director Steffen Krause explained, the project stays true to its original spirit while becoming more viable under private leadership. This shift has injected fresh momentum.
The Roadmap to 2029
The timeline is clear and exciting:
- 2026: Seismic measurements kick off to map the subsurface precisely and identify the best drilling spots.
-2027: The first deep wells begin—two boreholes targeting that hot 128°C reservoir.
-2029: Commissioning of a 7 MW geothermal plant, capable of supplying heat to the entire town area.
The heat extracted will feed into a local district heating network, operated in partnership with a regional utility for smooth delivery to end users. Early talks with anchor customers—clinics, the town hall, the Kurhaus, and others—have been very promising. These large consumers provide stable demand, making the economics even stronger.
What makes Bad Bevensen special? It already benefits from geothermal resources. The town's famous Jod-Sole-Therme (iodine brine spa), the only mineral healing bath in the Lüneburger Heide, draws over 800 visitors daily using shallower thermal waters. The new project taps deeper, hotter layers for district-scale heating—building on nature's gift while expanding its benefits to everyday life.
Why This Matters: Geothermal's Bigger Picture
Bad Bevensen's story is part of a broader awakening in Germany and Europe. Deep geothermal energy offers baseload renewable heat—available 24/7, independent of sun or wind, with minimal land use and virtually zero emissions during operation. In a country pushing hard toward climate neutrality, projects like this reduce dependence on volatile gas markets and cut CO₂ dramatically.
The federal government's support through insurance-backed funding shows growing confidence in geothermal as a scalable solution. If successful, Bad Bevensen could become a model for other small towns and cities sitting atop untapped heat reservoirs.
A Warmer, Greener Tomorrow
Picture walking through Bad Bevensen in winter 2030: Snow dusts the heath, but homes glow with cozy warmth from below ground. The spa continues welcoming guests, now joined by a town proudly powered by Earth's inner fire. No more worries about energy prices spiking or supply disruptions—just steady, local, renewable heat.
This isn't just about one town. It's proof that the good really does come from below—reliable, clean, and ready when we need it most.

As NULLCOZWEI and Bad Bevensen move forward, the geothermal community watches closely. Seismic trucks rolling in this year mark the start of something big. By 2029, a small spa town in Lower Saxony could light the way for much larger transitions.
The heat beneath our feet has always been there. Now, we're finally reaching down to claim it.
