Copenhagen, Denmark
The establishment and analysis of the FlexHeat heat pump was realized as part of the research and demonstration project “EnergyLab Nordhavn” that studied solutions for integrated energy systems in urban environments in a living lab established in the newly built area Nordhavn in Copenhagen, Denmark.
The FlexHeat heat pump was established in 2018 in the outer Nordhavn area. It is owned and operated by the local utility company HOFOR. The heat pump is an 800 kW two-stage ammonia heat pump that supplies heat to four cruiseship terminals and a large-scale warehouse via a local district heating grid. The system further includes two electric heaters á 100 kW each and a 100 m3 hot water storage tank.
The system has been designed to allow for flexible operation of the heat pump. This includes optimization of the operation schedule and potentially also providing frequency reserve to the power grid.
