Participating Countries - Denmark

Denmark aims for reducing CO₂ emissions by 75 % by 2030, while a major share of the CO₂ reductions from industries should be achieved by converting industrial process heating to heat pump-based systems. The Danish industry has therefore a strong interest in high-temperature heat pump systems and is represented by 2 partners in the Project 68.   The Danish working group is coordinated by the Center for Refrigeration and Heat Pump Technologies at the Danish Technological Institute (DTI). DTI is a leading research and development institute for industrial heat pump systems with advanced testing laboratories and has a strong focus on developing optimal solutions for technology suppliers and end-users. Besides the Annex on HTHP systems, DTI is coordinating and contributing to various national and international R&D activities focusing on decarbonizing industrial process heating and accelerating the transition towards more sustainable industrial productions. DTI was coordinating both the national working group as well as the international Annex 58 and will do the same for Project 68. DTU Construct is involved as research institution with the section of Thermal Energy, which is acknowledged for their expertise in modelling of heat pump and refrigeration systems, energy systems and industrial processes. DTU Construct has a long-track record of R&D projects in the field of industrial heat pumps and electrification of industry.
