In the European Union the power generation from wind and photovoltaic, a very unpredictable and fluctuating energy source, has increased significantly over the last years. With a lack of storage capacity for power in the national grids, energy balance demand rises from year to year. As a matter of research Fraunhofer UMSICHT is exploring a concept of implementing high temperature storages (HTES), for example pebble bed storages (so-called Pebble-Heater), in biomass power plants for high temperature heat storage. In times of low energy demand a fraction of the flue gas is diverted and used in a HTES to buffer thermal energy on a high temperature level. In times of high energy use, the power plant operates in condensation mode and with the stored energy the heat supply of the connected consumer can be maintained, e.g. for supply of process heat or district heating systems. The decoupling of heat and power generation leads to more flexibility in the operation of the power plants.
