Project 68 – Industrial High-Temperature Heat Pumps, Task 1: Technologies, 2025
The decarbonisation of industrial process heating has become a key focus of industrial manufacturing companies in their journey towards sustainable production. Planning and of process heating is a strategic activity realising the decarbonisation that requires a sophisticated roadmap over several years. Such roadmaps should be based on structured, reliable and independent knowledge about the current and projected status of technologies and their perspectives. In this context, the IEA HPT Project 68 on industrial high-temperature heat pumps has conducted a review in the fall of 2025 of industrial heat pumps with heat supply temp
