The Surge in Geothermal Energy Across Lower Saxony
Increased installation of geothermal power stations in Lower Saxony - Expansion of Geothermal Energy Plants in Lower Saxony

Embrace the warmth! More Lower Saxony residents are hopping on the geothermal energy train. As announced by the State Office for Mining, Energy and Geology in Hannover, there are now a whopping 26,600 geothermal plants in operation across the state, marking a significant increase since 2018.
Once just a one-trick pony, these plants have doubled their numbers in merely four years—from a humble 13,300 in 2018 to their current heights, extracting heat from depths of up to 400 meters below the surface.
But tread lightly—the installation pace has taken a breather. The authority says that while there was a spike in new builds from 2018 to 2022, reaching around 2,500 installations per year, this number dropped to 1,500 in 2024.
So, what’s cooking? Newer geothermal plants are packing more punch and diving deeper, according to Hans-Jürgen Brauner, head of the LBEG's Geothermal Service. More powerful equipment allows them to extract geothermal energy from greater depths, even if there are fewer plants than in previous years. Currently, there are over 650 large-scale plants with a heating capacity of more than 30 kilowatts throughout the state, with around 80 added in 2024 alone.
All hail Emsland! With 3,100 geothermal plants, it reigns supreme. Hannover comes in a close second with 2,300, and Cloppenburg stands proudly in third with 1,300. Other districts like Harburg, Osnabrück, and Bentheim each boast over 1,000 plants. But it's a cold world in the Harz, Lüneburger Heide, Wendland, and Solling regions, thanks to their meager plant count.
For those keeping score, the LBEG collected and analyzed data from responsible licensing authorities for their survey.
Deep Dive into Geothermal Energy in Lower Saxony 2024

With increasing attention focusing on sustainable energy strategies, deep geothermal energy in Lower Saxony holds immense potential, particularly for large-scale, commercial, and institutional applications.
Currently, major players like Sartorius have successfully launched climate-neutral laboratories that rely on geothermal energy for heating and cooling. Take a peek at their campus—it's powered by potent heat pumps that tap into the mightiest geothermal field in Lower Saxony, providing year-round, emission-free climate control. To sweeten the deal, electricity for such projects is supplemented with hydropower and solar energy.
Regulatory frameworks and technical advancements also support ongoing investments in deep geothermal. The LBEG, for instance, has upped the ante by requiring stricter integrity and safety standards for deep wells, including regular inspections and certification of technical experts. Companies like DEEP.KBB GmbH are ahead of the curve, providing certified experts to ensure underground installations are as safe and well-maintained as a Victorian tea party.
Meanwhile, the region continues to dive deep (literally) with geological research, striving for a better grasp of subsurface resources. They're even borrowing techniques from oil and gas exploration to analyze seismic data and map geological features suitable for geothermal development.
As Germany celebrates over 55% renewable energy in 2023, the role of geothermal as a reliable base-load energy source is looking more promising than ever. Its unique ability to provide both heating and cooling, regardless of the weather, makes it a valuable partner to solar and wind energy in Lower Saxony's energy mix.
Looking ahead, Lower Saxony stands at the doorstep of a booming geothermal energy revolution. With successful examples like Sartorius to learn from, the door is wide open for broader adoption across industrial, municipal, and residential sectors. What's more, upgrades to infrastructure and renewable energy grids, stricter regulations, and the discovery of new geothermal reservoirs will likely propel Lower Saxony further into the sustainable energy age.
| Aspect | Current Status | Future Outlook ||-------------------------|-----------------------------------------------------|------------------------------------------|| Industrial Use | Sartorius campus uses largest geothermal field | Expansion to more sites and cities || Regulatory Safety | Stricter deep well inspections, expert certification| Continued focus on safety and standards || Research & Exploration | Improved seismic and geological mapping | More reservoirs likely to be identified || Integration | Part of holistic, renewable campus energy systems | Increasing role in municipal energy grids|
Lower Saxony's race to a sustainable future is well underway, and geothermal energy is its key ally [1][2][3].
- The surge in geothermal energy usage in Lower Saxony is not only limited to households, but also extends to the industry sector, as demonstrated by Sartorius' climate-neutral laboratories that harness geothermal energy for heating and cooling.
- In the realm of environmental-science, Lower Saxony is making strides in geological research, utilizing methods from oil and gas exploration to analyze seismic data and map geological features suitable for geothermal development.
- To ensure the safety and integrity of deep wells in the context of geothermal energy, the LBEG has implemented stricter regulations, including regular inspections and the certification of technical experts, as exemplified by companies like DEEP.KBB GmbH.
