We are happy to announce that the yearly report for Task 1 “Technology developments” of the IEA HPT TCP Project 68 has been published and is now available for download here. The report presents a summary of the review of industrial high temperature heat pumps carried out in the fall of 2025. Information about more than 80 technologies and real-life projects of industrial heat pumps with heat supply temperatures above 100 °C with a minimum TRL of 4 has been collected and analysed, providing a clear picture of the current state of the technology and expected future developments.
The most significant technology developments highlighted in the report are:
- A pronounced shift toward natural working fluids
- New and more commercially mature technologies reaching higher temperatures and larger capacities
- A sharp rise in demonstration activities
Have also a look at the new webpage for Task 1 for the most updated information on industrial high-temperature heat pumps and interactive features.
