Increasing number of geothermal energy facilities in Lower Saxony region

Heatin' Up Lower Saxony: Geothermal Energy on the Rise! 🔥

Enhanced Geothermal Power Installations in Lower Saxony on the Rise - Increasing number of geothermal energy facilities in Lower Saxony region

Hey there! Guess what? More folks in Lower Saxony are warming up their homes with geothermal energy! As of now, there are a whopping 26,600 surface-near geothermal plants humming away across the state, says the State Office for Mining, Energy, and Geology in Hannover. This number has more than doubled since 2018—when just 13,300 plants were in operation—and these energy extractors help draw heat from as deep as 400 meters below the surface.

But, listen up: the rate of new construction has started to slow down, according to the authority. Although the number of newly built plants surged from 2018 to 2022, peaking at around 2,500 per year, it's fallen back to 1,500 in 2024.

Here's the twist: these new plants are packing more power and pulling geothermal energy from greater depths, explains Hans-Jürgen Brauner, chief of the Geothermal Service at LBEG. "You see, although we're building fewer plants, they're larger than in previous years."

Now, there are a hearty 650 large-scale plants with more than 30 kilowatts of heating power scattered throughout the state. Around 80 of these powerhouses were built in 2024 alone, with the number of large-scale plants built in a year more than doubling since 2018. The rest, mostly for private homes, have between 4 and 15 kilowatts.

Finally, let me tell you this: the Emsland region has the most plants—an impressive 3,100, followed closely by Hannover with 2,300 and Cloppenburg with 1,300. Harburg, Osnabrück, and Bentheim all have over 1,000 plants, while the Harz, Lüneburger Heide, Wendland, and Solling regions have comparatively fewer due to their low population density.

Now, for some interesting tidbits: Sartorius, a company in Lower Saxony, is using geothermal energy to go carbon neutral by harnessing the state's strongest geothermal field for heating and cooling. The German Research Centre for Geosciences (GFZ) is also making waves in deep geothermal energy innovations. Lastly, tighter regulations have been enforced for deep wells in Lower Saxony, requiring regular inspections by external experts [1][2][5]. Sources [#footnote2] [#footnote5)
