New IIR Informatory Note on high-temperature heat pumps

IRR’s latest Informatory Note demonstrates that high-temperature heat pumps are a key technology in the decarbonisation of process industries. 

The IIR has just published a new Informatory Note on high-temperature heat pumps (HTHPs) for industrial applications prepared by Dereje S. Ayou, José Miguel Corberan and Alberto Coronas. 

It highlights that HTHPs are a prime option for harnessing the huge energy potential of waste heat in processing industries, improving their energy efficiency and reducing their carbon footprint. The HTHP market is dominated by vapour compression technology, but few equipment of this type are capable of delivering heat at temperature levels (over 90°C) compatible with the needs of the food, chemical and paper industries in particular. Current research and development activities are therefore focused on technologies and working fluids adapted to these needs. Absorption heat transformers and absorption-compression heat pumps are the most promising solutions in this respect. 


The note also includes a series of recommendations aimed at developing this technology.

A Summary for policymakers outlining the main conclusions and recommendations of this Informatory Note is also available in open access.
