"Open Sesame" – Modelling Tools for Energy Storage
The aim of the IEA ECES32 project “Open Sesame” is to provide models for energy storage, which are derived from high level scientific models and then – as simplified models – available as open source. These models must have sufficient granularity (temporal resolution and technological variety) and include the most important parameters (technical, economic). Also, these models must be present as a generic mathematical-empirical, open description so that they can be incorporated into all other energy system models. In addition to this model description, reliable, standardized consumption and feed-in time series are required to achieve comparable results for different energy system models. The demonstration of these models takes place in an open source environment. Scientific validation is carried out by applying these energy storage models in a current energy system model and analyzing new business and research questions.
Prof. Dr.-Ing. Christian Doetsch is working for 20 years in the field of energy research at Fraunhofer, the largest research center in Europe for applied research. He is responsible — as the director of the energy division at Fraunhofer UMSICHT — for electric and thermal energy storage, chemical conversion, power-to-x technologies, and energy system optimization. The focal point of his current work is the integration of renewable energies into the energy system.
