The aim of our work is to develop efficient energy systems. We develop and optimize energy-efficient and economical energy systems through the interaction of energy supply, distribution, storage, and use. The focus lies on local energy systems and the integration of renewable energies.

Energy Supply Systems

We develop local energy systems to supply to properties through to urban quarters. We investigate dynamic system behavior and carry out energy-efficiency evaluations. In addition, we prepare demonstration projects and implement promising energy concepts together with our partners.

Energy System Optimization

The future of energy supply is regenerative, but also dynamic and diverse.  Short-term fluctuations in regenerative electricity generation must be compensated for by a large number of small, spatially distributed plants. At the same time, the sectors of electricity, heat and gas supply, and production and mobility are increasingly converging. These complex requirements are countered by a multitude of system variants and operating options. With the help of mathematical optimization models, we develop energy-efficient and economical energy systems. We optimize the dimensioning and operation of energy supply plants and storage facilities in future markets.

Hybrid urban Energy Storage®

Intelligent, efficient and reliable

Reference projects of the department Energy Systems


Stadt als Speicher

Virtual storage of

Fraunhofer UMSICHT has investigated how virtual energy storage systems can be practically implemented in urban regions. The results show which systems should preferably be integrated and how the technical connection and control can be realized.



Redox flow batteries for private homes

Fraunhofer UMSICHT is researching the development of innovative energy concepts and the system integration of redox flow batteries using photovoltaic systems in private homes at its model site for renewable energy supply in Herne.



Concept for combined heat and power generation

A new concept for combined heat and power generation reacts to fluctuating market prices and compensates for bottlenecks in the local grid. The combination of CHP with heat storage and power-to-heat is a building block in the energy transition.



Hybrid Energy Storage Hospital

The project "Hybrid Energy Storage Hospital" (HESKH) deals with the question of whether and how the supply systems of hospitals can be used for electrical energy balancing. In addition to determining the potential itself, the project also examines the importance of precise heat load forecasts for the planning of flexible system operation.



Making cooling supply systems more flexible

The aim of the project "FlexKaelte" is to develop basics for the evaluation of the flexibilization of cooling supply systems and to show the potential for electrical energy balancing in Germany.
