Abstract:
To increase the share of renewable energies in district heating systems is a key issue to reach the environmental targets within 2030. In this context especially biomass and solar thermal energy are the main renewable sources to achieve these goals. In the past the combined use of biomass and solar for district heat production was considered as an economic competition. In the meanwhile it turned out that for medium and large scale applications the advantages of both can be integrated successfully into systems but creates technical and economic challenges to be solved. Within the European project "SUNSTORE 4" a large-scale district heating system based on hybrid solar in combination with a biomass CHP unit has been demonstrated in Marstal-Denmark and a 3 year monitoring period was performed. The new facility in Marstal consists of a 15,000 m2 solar system, a biomass CHP plant based on a thermal boiler, an ORC with 3.2 MW heat and 750 kWel electric output and a flue gas condensation with 1.1 MWth, a 75,000 m3 pit heat storage and a 1.5 MWth heat pump with CO2 as refrigerant. All units have been tested and evaluated successfully and the expected design parameters can be clearly achieved.
