Near-surface geothermal energy 

The energy transition is one of the greatest challenges of the 21st century and near-surface geothermal energy is a sleeping giant of the thermal energy transition. The term near-surface geothermal energy refers to geothermal applications with installation depths in the top five metres of the ground. The systems primarily include horizontal and vertical geothermal collectors as well as special designs such as trench collectors, ground ice storage, large collector systems, and others.

The Institute for Energy and Building (ieg) at Nuremberg Institute of Technology conducts research in the area of near-surface geothermal energy increasingly in the computation and optimization of these systems in order to make them available for broader use as a key technology for the energy transition. Our know-how spans from detailed numerical planning across intensive monitoring to continuous optimization in established systems. All systems - from the smallest collector systems to ground ice storage to large collector systems - can be extensively investigated and measured. Numerical simulation procedures are continually validated and calibrated to ensure the system statuses that are computed are as close to reality as possible. Over ten years of valuable experience in application-oriented research projects in this field provide the basis of our expertise.
