Demonstrating high-temperature heat pumps at different integration levels

The project aims at developing and demonstrating two high-temperature heat pump (HTHP) systems at different integration levels. The HTHP System I will be integrated on process level with a pellet dryer of fish feed and demonstrated with a capacity between 300 kW to 500 kW. This system will be based on a hydrocarbon cascade solution using semi-hermetic screw compressors. The HTHP System II will be integrated on utility level as a booster for a district heating system for supply of process heat at up to 160 °C, and with a capacity of 1.3 MW to 1.5 MW. This system will be a cascade system with butane and steam using novel industrial screw compressors. The technical developments are supplemented with research activities focusing on the analysis of sector integration benefits obtainable from integrating district heating for industrial process heat supply. The developments are considered as a key-technology for enabling decarbonization of industrial process heating and facilitating sector integration and do thereby directly contribute to reaching the ambitious Danish climate targets. The consortium comprises leading experts for the development of HTHPs from Denmark, Italy, and Sweden.
