Thermal and chemical energy storage are both necessary components for a successful transformation of the energy system towards sustainability, helping to buffer fluctuating renewable energy sources on the intermediate and long time scale. Many approaches are discussed in the literature, but neither the storage type and storage molecules or even elements, nor the assessment criteria for different storage possibilities are clear.

For thermal energy storage different temperature levels, storage sizes, materials and conversion technologies are discussed, including combinations of heat pumps and organic Rankine cycles (ORC), the combination of steam cycles or Brayton cycles etc. An open discussion of scientific and technological questions, possible efficiencies and realistic amount of storable energy is aimed.

Also, for chemical energy storage, including the formation of transportation fuels, there will not be a single way, but in order to be relevant for the energy transition, some -not yet defined- minimum criteria have to be fulfilled, which have to be quantitative. Integrated conversion of species and energy is a very rational way of using restricted resources but implies the intense collaboration and interconnection of chemical industry with energy providers, which may even reduce flexibility.

At the same time physicists, chemists, engineers and economists propose different approaches, according to the point of view of their discipline, often without considering restrictions and viewpoint from other disciplines. Within this seminar, experts in different fields, including the industrial viewpoint and the systems perspective, should discuss openly their thoughts and their research about the following topics:

• The scientific and technological state of the art and open issues of different approaches for thermal andchemical energy storage.

• General and objective criteria for the assessment of different thermal and chemical energy storage and re-usage schemes and the weighting of the importance of different criteria like efficiencies, storage power, infrastructure,availability, flexibility and ecologic impact.


The conference language will be English. The Wilhelm and Else Heraeus-Foundation bears the cost of full-board accommodation for all participants.
