On October 28th, the IEA’s Technology Collaboration Programme on Heat Pumping Technologies (HPT TCP) hosted a successful National Experts meeting in conjunction with the European Heat Pump Summit. The meeting’s main goal was to generate fresh ideas and proposals for future HPT TCP Annexes (international collaboration projects). Dr. Caroline Haglund Stignor of the Heat Pump Center welcomed the attendees and gave a presentation of the key findings from the mid-term evaluation of the HPT’s Strategic Work Plan 2018-2023.
Four quick presentations were presented to establish the scene and kick off the workshop discussions. Dr. Aaron Gillich, who works for BSRIA/LSBU in the UK, provided an introductory presentation on sector coupling since we need to explore and demonstrate how the technology can enable sector coupling to improve energy efficiency and increase the share of renewable energy in the mix by providing flexibility.
Dr. Bassam Badran, a KTH University researcher, offered solutions that utilize both the cold and warm sides of the thermodynamic cycle. He highlighted, heat pumps are efficient and reliable devices to heat and cool useful media, and when equipped to do so, they can also produce simultaneously heating and cooling energies to help reduce the global energy consumption of buildings. However, in some cases, the simultaneity of heating and cooling is not as frequent as desired.
The challenges and prospects of alternative and new business models were explored by Thomas Barquin of Delta EE in the United Kingdom. It is inevitable that existing business models be further developed to match the complexity of customer demand services in order to drive mass deployment of heat pumping technology and increase affordability.
Dr. Veronika Wilk of AIT in Austria spoke about digitalization for heat pumping technologies since we need to understand how to cope with new obstacles and explore the potential presented by recent advances in this area (e.g. cybersecurity).
Following that, the attendees were split into four groups to debate the four themes. They spent 10 minutes per topic discussing the present status, aspirations, challenges, and solutions of each thematic topic. Following the heated debates and discussions, the groups were then invited to propose new topics for potential annex projects related to the themes.
The participants have proposed a significant number of ideas; all participants were then given the opportunity to vote for their favourite idea/s to take them forward; the following proposals have received a high number of votes and therefore were brought forward to the next stage.
- Survey of practical examples for sector coupling and a “Warts and all” evaluation of the implementation process + Heat pumps & electric vehicle.
- Identifying particular cases for good opportunities (for using both the warm and cold side of the thermodynamic cycle) at different scales, city, town, building, industry
- Developing/agreeing on common communication protocols for heat pump
- Heat pumps for circular economy
- Using data to improve technology
- Safety measures on flammable refrigerants
The workshop concluded with a quick update on the status of the new planned annexes that are now being discussed and developed within the HPT TCP:
- Heat Pumps for Drying (Dr. Thomas Fleckl from AIT, Austria)
- Heat Pumps in Positive Energy Districts (Dr. Caroline Haglund Stignor HPC, Sweden)
- Comfort and Climate Box solutions for warm and humid climates (Peter Wagener from Eigenaar BDH b.v, The Netherland)
- Retrofit Heat Pump Systems in Larger non-Domestic Buildings (Oliver Sutton from BEIS, UK)
- Heat pumps in High-Density Cities (Dr. Marek Miara from Fraunhofer ISE, Germany)
- Selected topics in Heat Pump Acoustics, (Dr. Thomas Fleckl from AIT, Austria)
Evaluation and Demonstration of actual Energy Efficiency of Heat Pump Systems in Buildings (in collaboration with EBC TCP), (Dr. Caroline Haglund Stignor from HPC, Sweden)
