How flexible is the heat supply?
Due to the relatively low investment and operating costs for thermal energy storage systems, they can be used to achieve various storage goals. Potentials for mutual optimization in the context of sector integration of the electrical and thermal supply systems are particularly interesting. To decide which storage system is the most suitable, one can choose between a large variety of possible heat storage systems, e.g., in dedicated storage tanks, storage in the building envelope, or thermal grids.
Specifically, we look at the following questions:
- How much thermal storage capacity do we need for the heat transition?
- Will seasonal storage be used centrally and decentrally in the future?
- Which thermal storage technologies should be preferred?
- What role do flexible electric heating systems play?
