“JenErgieReal” Living Lab for the Energy Transition
Integrated Energy Supply for Cities

Ensuring a sustainable supply of electricity and heat in cities requires an overarching view of all energy-producing and -consuming sectors. In selected districts in Jena, experts will demonstrate how energy producers, storage systems, and consumers can be intelligently linked.

Generating Electricity and Heat More Efficiently with Solar Energy

Photovoltaic thermal systems can generate electricity and heat with solar energy. Funded by the Federal Ministry for Economic Affairs and Climate Action, researchers have optimised this system in three ways: they developed new collector concepts, efficient production and optimised operation in combination with heat pumps.



The potential of shallow geothermal energy for Germany’s heat supply is to be utilized more effectively. To achieve this, a nationwide standardized database is to be created in the WärmeGut project.

New: Large-Scale Heat Pumps in Germany’s District Heating Networks


A large proportion of Germany’s CO2 emissions can be attributed to the supply of heat. Large-scale heat pumps powered by greenhouse gas-free electricity could help the country to reduce its CO2 emissions. In the living lab for the energy transition focused on the installation, operation, monitoring, and system integration of large-scale heat pumps (LHPs) in district heating networks, these systems will now be connected to district heating networks at various types of location.
