Geothermal Laufzorn II

Drees & Sommer is supporting Erdwärme Grünwald GmbH in expanding deep geothermal energy for climate-friendly heat supply. The new Laufzorn II site is expected to make a significant contribution to the regional heat supply in future.

The project comprises 4-6 deep wells in the “Grünwald” permit field at a depth of 3,600 - 4,000 m (true vertical depth). For this purpose, a collection drilling site will first be constructed, on the site of which an above-ground heating plant will be built after drilling. From there, a new district heating pipeline will be built to feed into the regional district heating network. The area not required for operation will then be renaturalized.

The measures also include the planning and approval process as well as coordination with the relevant authorities.

​A particular challenge of the project is the specialized drilling technology used to drill the deep borehole. The three sub-projects of drilling, heating plant, and district heating pipeline also require close coordination in order for the site to come into operation as soon as possible. The strict ecological requirements in the landscape conservation areas also require special attention.

It is a project that demonstrates the enormous potential of geothermal energy. This is because deep geothermal energy as a base load carrier can become a relevant component of the green heat transition in Germany and sustainably secure the supply of green heat to cities and municipalities.
