IEA HPT Annex 58: High-Temperature Heat Pumps
Short Description
IEA HPT Annex 58 provides an overview of the technological opportunities and applications of high-temperature heat pumps. Furthermore, recommendations and materials were developed to accelerate the transition to a heat pump-based process heat supply. The project aims to increase understanding of the potential of the technology among many stakeholders, such as end users and manufacturers, and reduce barriers to implementation. It also aims to increase the international visibility of national R&D activities in this area.
The project is divided into four main topics:
- Introduction to the topic of high-temperature heat pumps and development perspectives (Task 1)
- Concepts for typical heat pump applications (e.g.: steam generation and hot water generation), as well as integration concepts for selected industrial processes (Task 2)
- Contribution to the development of strategies for a transition to a heat pump-based process heat supply (Task 3)
- Recommendations for the definition and testing of specifications for high-temperature heat pumps (Task 4)
The results of the international project are published e.g. in the form of task reports and descriptions on the IEA HPT website.
The introduction to the topic of high-temperature heat pumps includes the description of basic definitions and principles, as well as the presentation of commercially available high-temperature heat pump technologies that are currently under development. For this purpose, corresponding product descriptions from manufacturers were collected and published. Descriptions of demonstration projects were also collected.
In May 2024, 39 product and 16 demonstration project descriptions were available on the IEA HPT Annex 58 website - including three product descriptions from Austrian heat pump manufacturers and two demonstration project descriptions submitted by the national project team. The associated task report also presents the national application potential and selected research projects of the national team.
Descriptions of the national project team on heat pump concepts for steam generation as well as integration concepts for brick drying and extrusion cooking are included in the Task 2 report.
In Task 3 of the international project, which was led by AIT Austrian Institute of Technology, a guideline was developed to support end users in developing a decarbonization strategy, whereby the heat pump will play an important role in a lot of decarbonization strategies.
In Task 4, the focus was on defining and testing heat pump specifications, and three guidelines were developed, with the national team developing, for example, a checklist for end users to support them in collecting information for planning a heat pump project.
