Heating/cooling sector: How can fossil and nuclear power be replaced by RES? Efficiency  Will reduce the heat demand dramatically  Active heating and cooling demand will remain Biomass  Flexible, storable  Limited ressources, needed for electricity production and transport as well Geothermal energy  Can fully replace other heating and cooling systems  Limited resources Heat pumps  Can fully replace other heating and cooling systems  Electricity or gas is needed in addition Solar thermal energy  Biggest potential under all RES  How to make it useable?

Goal 2020: 1 m² collector area per European 2020: 340 GWth = 1 m²/inhabitant 13 Increase the market volume from 2 to 80 GWth (3 to 110 Mio m², about 30 Bln Euro turnover) Average market growth: 34% annually Factor 25 in energy capacity and production Total installed solar thermal power in Europe

Solar Thermal Vision 2030 of the Solar Thermal Technology Panel of the ETP – RHC New buildings 100% solar heated buildings will be the building standard Existing building stock Solar refurbished buildings, > 50% solar heated, will be the most cost effective way to refurbish the building stock Industrial and agricultural applications solar thermal systems will cover process heating and cooling demands District heating and cooling networks will be widely solar assisted Overall goal: 50% of the low temperature need up to 250°C will be provided by solar thermal

European Technology Platform – Renewable Heating and Cooling  Important driver of RES – RHC Innovations  Tasks: Vision 2030, Strategic Research Agenda, Implementation  Actors: Industry, Research Sector and Policy  Endorsed by European Commission in October 2008 Solar Thermal Research Agenda was published in Dec 2008 Download: Structure of ETP-RHC

4 strategies needed to develop the full potential of ST 1.The number of solar thermal systems has to be sharply increased 2.The share of solar thermal energy per building has to be increased step-by-step up to 100%

From DHW to 100% solar heated buildings Share of solar thermal energy of the heat demand of a building Solar Domestic Hot Water Heating 10%-20% SDHWH + Space Heating Support 20%-30% „Solar house 50+“ Mainly heated by solar SDHWH + Space Heating (support) 50% %

4 strategies needed to develop the full potential of ST 1.The number of solar thermal systems has to be sharply increased 2.The share of solar thermal energy per building has to be increased step-by-step up to 100% 3.ST has to be introduced in new market segments like public buildings and the commercial sector

Large Solar Thermal Systems Multi family homes, hotels, hospitals, nursing homes etc. have a high share of the overall heat demand. Large solar thermal systems for that applications must be well designed, especially regarding heat management. Image: Solvis Image: Wagner & Co

4 strategies needed to develop the full potential of ST 1.The number of solar thermal systems has to be sharply increased  market deployment measures are needed 2.The share of solar thermal energy per building has to be increased step-by-step up to 100%  market deployment and R&D measures needed 3.ST has to be introduced in new market segments like public buildings and the commercial sector  market deployment and R&D measures needed 4.New ST applications has to be developed like solar assisted cooling, district and process heating  strong R&D and first market deployment measures are needed

Creating favourable and stable market frame- works through coherent support strategies

Activating ST markets with offer and demand side marketing campaigning

Vertical approach – EXPERTS: Implication of the whole value chain: co-operation with Manufacturers, traders, installers, planners, architects,… Horizontal approach – GENERAL PUBLIC : Sensibilisation of the general public and information of early adopters target groups Circular approach - REGIONAL : Involving politics on the national, federal and local level Activation of regional expert networks « Solarschulen 2000 » “Solar - na klar!” campaign strategy

EU-Wide Campaigning 27 National Campaigns Regional & Local Campaigns “ ” Energy Smart Building Stimulation Campaign Budget: 500+ Million Euro (€1 for each European) Generated RES-Heat / Energy Efficiency turn-over of 10 Billion Euro  500 million Europeans  Campaign reaches 10%  1 of 10 reached calls for free info activation kit *  1 of 4 activated invests *  = 1,25 million investors  ø Euro investment per capita  = 10 billion Euro RES-Heat/EE turn-over  The Input/Output Factor is 20!! * ) Empirical numbers drawn from Germany’s „Solar - na klar!“ campaign

Economic impact of Solar Heat:  Solar thermal turn-over in 2008: –>3 billion Euro in Europe –1,7 billion Euro in Germany  European Goal 2020 : 40+ billion Euro  Solar thermal job creation today: – in Europe – in Germany  European Goal 2020: jobs We replace imported fuels with local jobs!

Conclusions  Most European ST markets got the wake-up call  Vision 2030: 50% of the heat demand will be provided by solar thermal energy  A R&D and innovation push is necessary; a Strategic Research Agenda has already been worked out by the ETP-RHC  Now, R&D budgets and resources must be increased significantly by politics, industry and research institutes  A supporting and stable market framework must be in place  ST markets must be activated with offer and demand side marketing campaigning
