8 Expertise in Decentralised Energy Best case commercialisation time-frames /17+ PEMFC SOFC

9 Expertise in Decentralised Energy Market outlook to High growth scenario Policy improves Prices fall quicker than expected Strong customer demand High growth scenario Policy improves Prices fall quicker than expected Strong customer demand Number of mCHP Annual Sales per Year (≤5kW)* Potential wildcards 1.Low cost fuel cell or low cost engine – ICE or ORC? 2.Surge in customer interest 3.Shale gas revolution & rapidly rising electricity prices 4.Innovative ‘micro-CHP for free’ contracting model ~201,000 (~30% fuel cell) [€5-8k) ~98,000 (~30% FC) [~€12k] ~30,000 (~50% FC) [€15-18k]

10 Expertise in Decentralised Energy Main European markets for mCHP ≤2 kWe CHP

11 Expertise in Decentralised Energy 3 opportunities for mCHP in a hydrogen economy H fed into a gas grid Local H networks House by house

12 Expertise in Decentralised Energy 3 opportunities for mCHP in a hydrogen economy H fed into a gas grid Reduces emissions Makes mCHP look even better No major technical issues

13 Expertise in Decentralised Energy 3 opportunities for mCHP in a hydrogen economy Local H networks New build focus Low volumes PEM FC without reformer – cheaper & simpler Denmark is pioneering

14 Expertise in Decentralised Energy 3 opportunities for mCHP in a hydrogen economy House-by-house Electrolyse when prices are low Store the H locally, eg oil tanks Generate electricity when prices are high IRD approach

15 Expertise in Decentralised Energy House-by-house 15 Improved performance and reduced CAPEX & OPEX of Fuel Cell-based systems Reduced CO 2 emissions for electricity and heat generation Avoid technical barriers of hydrogen distribution (and associated investment) η P AC  H 2 : 75% η P AC  P TH : 15% η: 99% η H 2  P TH : 44% η H 2  P AC : 50% η: 99% Overall Efficiency P AC  H 2  P AC : = 37% P AC  H 2 + P TH  P AC + P TH = 85% Overall Efficiency P AC  H 2  P AC : = 37% P AC  H 2 + P TH  P AC + P TH = 85% Source: IRD Fuel Cells A/S

16 Expertise in Decentralised Energy Challenges for mCHP in a hydrogen economy 16 Challenges Potential for reduced spark spread Minor modifications for any technology with H 2 >1% energy content Further modifications required when H 2 > 5% Variation in H 2 blends presents a major technical issue

17 Expertise in Decentralised Energy Conclusions & Research Priorities 17 Research Priorities How will spark-spread evolve with widespread H 2 introduction? Spark-spread dictates financial savings from micro-CHP Technology innovation to cope with H 2 –NG blend variations variations driven by renewable intermittency System integration of micro-CHP, electrolysers & storage historically, R&D funding has not focussed on integrated systems Conclusions Micro-CHP is well placed to deliver benefits in a future hydrogen economy: additional CO 2 emission savings lower energy bills Integrating micro-CHP with on-site hydrogen production can: decrease losses, increasing round trip efficiency (for electricity & heat) distributed storage solution avoids investment in NG network upgrades
