1 An initiative for decarbonising the EU heating sector 1

2 1 Why is it crucial to decarbonise the heating & cooling sector? 2

3 In nations adopt climate agreement: 2 C max, better yet, 1.5 C 3

6 Final energy demand for EU28 by end-use for H/C in all sectors in 2012 [total: TWh] 6 Cooling =326 TWh 5%!! % values apply on total! Source: Fraunhofer ISI et al. (2016): Report WP 1, p.83

7 Interim conclusions: Decarbonising society without decarbonising heating and cooling is not possible Decarbonising heating and cooling can be done based on available technology Social instead of technical innovation Set the legal framework right 7

8 Re-think the heating industry HP business models R&D manufacturing installation maintenance re-design re-tool re-skill within 35 years 8

9 The DecarbHeat Initiative The DecarbHeat initiative aims to bring together the major players of the heating and cooling industry and all major stakeholders in society and policy-makers to turn the vision of a 100% decarbonised heating and cooling system in Europe by 2050 into reality. DecarbHeat visionmission: 100% decarbonised heating and cooling system in Europe by 2050 DecarbHeat industry pledge DecarbHeat policy requests DecarbHeat support document 9 DecarbHeat Industry plattform

11 A possible pathway towards a 2050 energy system UK Building Stock 11 Decarbonising Heat in Buildings Dense Urban 22% Suburban 59% Rural 19% Lower energy demand in all sectors through increasing thermal efficiency of buildings and changing consumer behaviour High efficiency condensing boilers remain a useful technology in this sector into the 2030s Why we must decarbonise Europe's heating sector EHPA Heat networks are a more efficient option for denser urban areas where there is limited space for individual heat pumps. Coupled with heat storage they can help balance the grid. è Industrial heat pumps can decarbonise heat networks Gas absorption heat pumps use gas more efficiently as do hybrid systems containing a boiler and an electric heat pump High electric heat pump penetration faces fewer barriers in homes that are less clustered, starting with buildings off the gas grid, which are more likely to have space and be using high carbon and more expensive fuels like heating oil.

12 2 What is renewable cooling? 12

13 (my) 1st paradigm of cooling Cooling requirements are directly related to solar irradiation 13 Source: Source: own

14 (my) 2nd paradigm of cooling Whenever you need cooling you can have heating for free Auxiliary energy electricity/gas can be RES Discharge to Environment (air/water) OR Air Water Ground Ambient energy compress Use cold evaporate condense heat heating cooling Recovered energy Energy source è This side is cooled expand Heat pump Energy sink! This side is hot 14 Renewable cooling from eat pumps? EHPA meeting with Marie Donnelly

15 High ambition needed to decarbonise heating and cooling in cities, regions and society 15

16 Background: heat pump market development è current development insufficient to unleash the potential 16

17 market development accumulated: 8.4 million units installed Countries EU 11 EU 12 EU 14 EU 14 EU 19 EU 21 17

18 heat pump benefits 2015: triple dividend Renewable energy contribution CO 2 savings Primary energy savings 92.9 TWh 23.9 Mt 55.7 TWh 18

19 market potentials if Sweden was everywhere - actual sales 2015 total: > 5 mio 19
