4 Closing the carbon cycle Renewable liquid fuel and chemicals from CO 2 to replace crude oil Power-to-Liquids Energy storage and grid load compensation to cope with intermittent renewable electricity Power-to-Gas Next generation combined heat and power (CHP) to reduce inefficient energy conversion Gas-to-Power Solid oxide cells (SOC) at the heart of each technology enable a closed carbon cycle 4/23/2013 page 4

5 Company Strategy Technologies for a closed carbon cycle Markets Power-to-Liquids refinery chemicals Power-to- Gas Gas-to-Power microchp offgrid smallchp Knowhow Product Conversion & synthesis Electrolysis (SOEC) Systems & services Fuel cell (SOFC) 4/23/2013 page 5

6 Stack technology 4/23/2013 page 6

7 SOFC stacks and modules sunfire uses the staxera stack technology. A single SOFC unit is stacked to a 30 cell stack and integrated into a module with insulation and gas and el. connections. The target price for the mass market is 500 1,000 EUR per kw of installed power for the stack (price stack = 50% of price system) W W W Repeating unit / single cell SOFC stack / 30 cells Integrated stack modul/ 60 cells + insulation not yet an entire system! 4/23/2013 page 7

8 SOFC Stack MK % fuel utilization High electrical efficiency Good start up and shut down capability Low pressure drop & parasitic losses Redox stability 4/23/2013 page 8

12 Performance map SOFC stack The performance map of the SOFC stack shows the broad operation range of SOFC stacks. A low fuel utilizations and low voltages (=low efficiencies) high power can be reached. However higher efficiencies are achieved in part load operation Current density [A/cm²] Current [A] Stack voltage [V] Stack Power [kw] Stack efficiency [%] Fuel Utilization [%] Fuel flow rate [Nl/min] 4/23/2013 page 12

13 Lifetime & Degradation Lifetime Degradation rate Comment 20,000 h ~ 1% / 1,000 h One ISM in system test in lab environment More than 10,000 h ~ 0.5% / 1,000 h Sereval stacks and ISM Systems field test Stack test in Lab At test of h end of stack life is not yet reached. More liftetime results will be acquired in ongoing field tests 4/23/2013 page 13

14 Total cost of ownership Power density [kw/stack] Production cost [EUR/Stack] Lifetime [Degradation/1.000 h] The customer value: Lowest price in /kwh over the lifetime 4/23/2013 page 14
