Goal 7 for affordable and clean energy of the United Nations has the following subgoals;<\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<ul class=\"wp-block-list\">\n<li>by 2030 to substantially increase the share of renewable energy in the global energy mix.<\/li>\n\n\n\n<li>by 2030 to double the global rate of improvement in energy efficiency.<\/li>\n\n\n\n<li>by 2030 to enhance international cooperation to facilitate access to clean energy research and technology, including renewable energy, energy efficiency, as well as advanced and cleaner fossil-fuel technology, and to promote the investment in energy infrastructure and clean energy technology.<\/li>\n<\/ul>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"wp-block-paragraph \">The objectives of the IEA HPT Technology collaboration programme is to support the energy security and to demonstrate applications in existing and new energy systems and buildings. Another objective is new cross-cutting, affordable solutions for heating and cooling, where heat pumping technology is a key element through collaboration with other TCP\u2019s, enabling energy savings, flexibility, and responsiveness in energy systems.<br>IEA HPT Annex 47, which ended in March 2019, focused on existing solutions and technology for heat pumps in district heating grids. This annex showed that up to 50% of heating demand in Europe could be covered by district heating and heat pumps can cover up to 25 % of the energy supply to the district heating grid. This means that the potential for heat pumps is large. Annex 47 showed that heat pumps can be integrated in different ways in the DH grid which means that the losses can be reduced, and the efficiency can be improved.<\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"wp-block-paragraph \">Annex 47 was joined by Denmark and Netherlands. As the interest in heat pumps in DHC has increased since the start of the Annex, is it expected that more countries are joining this new Annex. From IEA DHC, especially the German partners have shown an interest.<\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"wp-block-paragraph \">This new Annex will focus more on coming technologies and the possibilities of heat pumps to increase the flexibility in energy systems with different sources such as PV, wind-power, and biomass and where end users can be consumer or prosumer or both (Multi-Vector). Heat pumps in DH systems provide many benefits, since they enable the possibility of running DH systems at lower temperatures, which increases the possibilities of using waste heat. Thus, the grid can run more efficiently as the heat losses can be reduced.<\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"wp-block-paragraph \">The implementation of District Heating and Cooling (DHC) systems and heat pumps in these systems, is a solution to increase the overall energy efficiency in the public society and to minimize the use of fossil fuels. The implementation of heat pumps in DHC systems is a solution to use waste heat and ambient heat as well as a way to increase the share of renewable energy in DHC systems and in the entire energy system.<\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<h2 class=\"wp-block-heading p1\">Activities<\/h2>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"p1 wp-block-paragraph \">Particularly, the following issues will be elaborated:<\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"has-text-align-left wp-block-paragraph \">a: Show the potential of heat pumps in district heating and cooling systems (Task 1)<br>b: Describe demonstration, research, and development projects where flexibility is created by the implementation of heat pumps (Task 2)<br>c: Present and describe concepts where heat pumps are implemented in DHC networks (Task 3)<br>d: Describe the kind of flexibility and the potential created by heat pumps in DHC networks and to the electrical grid (Task 4)<br>e: Identify and present business models with heat pumps in DHC networks and in different electrical markets (Task 5)<br>f: Describe socio economical barriers and opportunities (Task 5)<br>g: Disseminate the information gathered in the Annex (Task 6)<\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<h2 class=\"wp-block-heading\">Publications<\/h2>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"wp-block-paragraph \"><a href=\"https:\/\/heatpumpingtechnologies.org\/publications\/annex-57-flexibility-by-implementation-of-heat-pump-in-multi-vector-energy-systems-and-thermal-networks-final-report\/\">Final Report&nbsp;<\/a><br><a href=\"https:\/\/heatpumpingtechnologies.org\/publications\/annex-57-enhancing-electrical-grid-flexibility-through-heat-2-page-summary\/\">2 page Summary&nbsp;<\/a><br><a href=\"https:\/\/heatpumpingtechnologies.org\/publications\/enhancing-electrical-grid-flexibility-through-heat-pumps-executive-summary\/\">Executive Summary&nbsp;<\/a><\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<h2 class=\"wp-block-heading\">Contact Person<\/h2>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"wp-block-paragraph \">Mr Michael A.
