1 ltancy for renewable energy in the built environment The market calls for innovations in solar thermal roducts, while the network of market regulation tightens Gerard van Amerongen vaconsult

2 Introduction he current 1 th generation solar thermal technology hanging is now a professional business nwards to the 2 th generation!

3 Introduction erard van Amerongen Background: research Up to 2001 head of department at TNO Delft Consultant renewable energy built environment Mainly European projects But also national projects Board positions Chairman Holland Solar and board member DE koepel Chairman DEPK (Zonnekeur certificate)

4 Solar thermal energy a market in distress fter a fast market growth The market drops since 2008 he Netherlands is not that ad but a very small market omething is going on Zonnewarmte Wth geplaatst per jaar

5 Solar thermal energy a market in distress he cause of market downfall is not evident Solar thermal energy still has a good public image Even with a less than optimal sales structure The European markets are not saturated With exception of one or two countries The quality of the products is good No major bad experiences have been reported by customers ome causes are known The economics are believed to be less favorable than PV No view on significant price reductions The economic crisis has started in 2008 But the PV market is later influenced and by a lesser extent

6 Solar thermal energy An urgent need for a new perspective ost price shows some ecrease but should by now show major decrease but not caused by technology nergy output increases n average but not caused by better technology pplications remain omplex With some exceptions he esthetics are not avorable The looks of a matured technology but we are looking at the first generation! The technology calls for the 2 th generation

7 Solar thermal energy An urgent need for a new perspective hallenges Significant price reductions 50% in 2020 and further decrease in the following years Improved performance per m 2 applicability esthetics Scientific breakthroughs on specific technology issues To support product innovations More involvement of universities and research organizations At a difficult moment: Network of regulations tightens Markets are not favorable

8 Tightening the net olar thermal devices evolve into regular products Professional requirements are set quality certificates (e.g. Solar Keymark) Ecodesign / energy labelling building regulations CE marking of collectors Comfortable for commercial trade, but technical adventures are risky business nowadays Costs for developing new products rises (testing and certification costs) Innovative products may not be able to comply to current standards

9 Tightening the net ompanies tend to consolidate R&D departments go for conforming to the regulations product testing and minor improvements Focus is on sales and survival And not market development he market retreats, while the future shows very ood opportunities for professional business Energy prices will keep on rising Gas boilers will be phased out Energy neutral buildings will be required

10 Solar thermal energy Need for innovations he markets calls for new innovative products The second generation solar thermal products Much cheaper, high output, easy and broadly applicable, high esthetic values ompanies need to be fed with technology reakthroughs: Discontinuous solar supply (compact, efficient heat storage) Maximum temperature (on/off switching) Heat transport system (alternatives for drain back and glycol) New materials (e.g. plastics, insulation,.)

11 Innovations known references trategic Research priorities Technology roadmap Solar heating and cooling (IEA SHC, 2012) Strategic research priorities (ETP, 2013) ommon message Long list of wanted innovations ranging from component developments to new product market combinations his may not be the final answer Much aimed at improving what we have, and broadening the markets for solar thermal Is this the recipe for a major break through? Let us look at some major innovation opportunities

12 Innovations aimed at discontinuous solar supply ompact efficient heat storage A means to a constant heat source like a boiler Simple installation design Summer surplus to the winter Triple the thermal solar energy potential Low demand on space Also applicable in Dutch dwellings Currently researched within Europe and The Netherlands

13 Innovations Pay attention to the looks! new look on collectors

14 Innovations On/off switch emperatures can rise up to 200 o Cor higher High temperature demand on the materials used, less options High pressures, less options Safety issues, complex safeguards magine this and than for temperatures up to o C, but without a reliable on/off button!

15 ption for on/off switch Innovations On/off switch Roller blind Switchable transparent cover Switchable reflector Drain back with absorbing fluid

16 Innovations Insulation materials ew more effective insulation Thinner designs Better insulation on collectors E.g. aerogel, evacuated, ranslucent insulation materials Insulation of the collector absorber Opportunities for integration Collector and storage E.g. aerogel, plastic structures, Aerogel 6 10x thinner

17 Innovations Putting several issues together eat transfer systems No fail prove option available aterials Collector components and casing Alternative for glass cover Piping Mass produced complex designs Less components Better looks

18 Innovations Putting several things together solar thermal system design Compact collector and storage in one Thickness < 10 cm Factory made

19 Innovations system design imed at new markets Heat distribution systems (e.g. decentralized fed in) Industrial applications up to 400 o C imed at future buildings Combination with heat pumps electrical backup heating n combination other related services Combi panels solar thermal and solar PV Optimal space utilization Better looks

20 A final word he solar thermal market is at a turning point Current technology is not enough Excellent opportunities for innovations Both on the market and technology, issues identified nput is needed from science: Challenging subjects can be identified Universities should be involved Students should make it there business ompanies should be involved Good opportunities in near future hanks for your attention!
