Japan is one of the countries which have committed to Net Zero 2050 and we also aim to nearly halve our GHG emissions by 2030. Heat pumps are regarded as one of key decarbonization technologies for in low-temperature industrial heat sector along with the building heat sector according to Japan’s Long-Term Strategy. In this context Japanese industry is active in the development and deployment of industrial heat pumps. The national team for this Project 68 consists of 1 research institute, 4 academic experts, 9 industrial partners, 2 information centers, and 1 national agency.

Research Institute

Central Research Institute of Electric Power Industry (CRIEPI) is a joint research institute of electric utility companies. CRIEPI is leading research and development for industrial heat pumps with a unique testing laboratory which can test various-type heat pumps up to 200°C and 600 kW. In addition to technology development and evaluation, CRIEPI provides consulting services to electric utilities, manufacturers and the government. As for the relationship with the IEA HPT activities, CRIEPI was also involved in Annex 35, Annex 48 and Annex 58.
