Final Report for HPT TCP Annex 47 – “Heat Pumps in District Heating and Cooling systems”

The Final Report for HPT TCP Annex 47 – “Heat Pumps in District Heating and Cooling systems”, has been finalized and can be downloaded at the Annex 47 web site: https://heatpumpingtechnologies.org/annex47/

You can also download the 2-page summary here.

Objective
The objective of Annex 47  has been to gather information and ideas for policy makers and decision makers and planners of energy systems in urban areas concerning the possibilities and barriers related to the implementation of heat pumps in DHC systems.

One objective has been to suggest how heat pumps can be implemented in both new and old district heating systems in the best way. The different types of integration has been described. The differences and possibilities in integration in both central and local systems has been described. The possibilities of increasing a larger share of renewable energy or using excess heat in the different systems by using Heat Pumps has been a focus area.

Conclusions
Annex 47 has shown that heat pumps can act as a balancing technology between the different energy grids. This can contribute to a reduction of CO2 emissions of 70% compared to today’s situation.

Watch Webinar: “Heat-pumping the future of district energy”

On March 28 the webinar “Heat-pumping the future of district energy” was arranged by CELCIUS .
If you missed it you can still watch it here!

In the Celsius talk webinar three participants from HPT Annex 47 presented results related to heat pumps in district heating and cooling systems. Svend Vinther Pedersen (DTI) talked about the work done within Annex 47 and the combination of heat pumps and district heating in general. Thereafter followed Roman Geyer (AIT), who talked about barriers and opportunities for large-scale heat pumps in district heating and cooling networks. Finally, Markus Lindahl (RISE) presented results related to optimizing the combination of heat pumps and district heating in multi-family houses. The webinar was ended with time for discussions and questions.

Webinar Invitation

Webinar Topic: Heat pumps in district heating grids
Today there is great interest in using energy more efficiently in order to reduce greenhouse gas emissions. With this in mind, a solution to increase the share of renewable energy in district heating systems is to introduce heat pumps. This technology can be a way to connect different energy systems, such as the electrical grid, the gas grid and district heating grid; it can also be the link between the need for cooling and heating and the reuse of excess heat.

District heating, in general, and heat pumps connected to district energy grids, in particular, are predicted to play a key role in the energy systems and energy supply for the future. With implementation of district heating it is possible to cover up to 50% of the heating demand in Europe, and heat pumps can deliver around 25 % of the energy to the district heating grid, according to the Heat Roadmap Europe 4 project .

Heat pumps can be a key technology in the future district heating grids in different ways. For example, heat pumps:

• can act as a balancing technology when the electrical production fluctuates.
• make it possible to utilize low temperature energy sources, and waste heat in the district heating grid.
• can phase out fossil fuels from the energy system.
• make it possible to use very low or ultra-low temperatures in the district heating grids.
• make it possible to minimize grid losses in the district heating grid.

IEA Heat Pumping Technologies Annex 47; “Heat Pump in District Heating and Cooling systems”
Today the Annex 47 regarding heat pumps in district heating systems is an important annex under the IEA Heat Pumping Technologies program because more and more countries have realized that district heating is a way to phase out fossil fuel.

Join us on Thursday March 28 at 10:30 for an interactive discussion!

HPT Annex 47 about HPs in DHC system is entering its final stage

Annex 47 – Heat Pumps in District Heating and Cooling systems, has been up and running since January 2015 and is now entering the final stage reporting results and conclusions. The operating agent Denmark has together with Austria, Switzerland and Sweden completed 38 extensive case studies, now published and available at the Annex homepage (Task 2).

The case studies are a collection of good examples where district heating and heat pumps have been successfully combined. Most of the studies are existing facilities and a few are research projects.

Objective
The Annex 47 objective has been to gather information and ideas concerning the possibilities and barriers related to the implementation of heat pumps in DHC systems. The ambition is to spread these findings to policy makers, decision makers, planners of energy systems in urban areas and other actors of importance.

Annex arrangement

The Annex has been structured into the following tasks:

• Task 1. Market and energy reduction potential
• Task 2. Description of existing DHC systems and demonstration and R&D projects with heat pumps
• Task 3. Review the different concepts/solutions
• Task 4. Implementation barriers, possibilities and solutions
• Task 5. Dissemination

The Annex will officially close in Mars 2019 and more reports and documents will be added during the winter. You will also find a “Market and energy reduction potential report” from all participating countries (Task 1).
