14 Storage cost(jpy/nm 3 ) tank cost study (1Euro= 100JPY) It depends on capacity cost and liquefaction speed (utilized availability). 50 With operating availability 90% and Project year 30 year CAPEX+OPEX ,000 10,000 Tank capacity (t ) 14

15 HyGrid Study Team (HGST) Japan car CO 2 Storage Renewable energy Electrolysis Renewable energy Electrolysis Electricity CCPP Co-generation Gas Engine Gas Turbine Fuel Cell Reduction Steel making for de-sulfur at oil refinery HyGrid Study Team (HGST) was established in September 2012 Expensive but high value for national interest Current target is Domestic Premium Utilization Development Renewable Electrolysis storage Countryside new user 15

16 HyGrid Study Team (HGST) Current study Renewable Electrolysis storage Countryside new user Matching of Electrolysis & Wind power? Surplus power of wind power or grid? PV? Biomass? Smaller scale? Pressurized hydrogen? Comparison with battery? Matching of local user? Direct hydrogen user? (not for electricity) Value of Domestic Premium Utilization Development? Societal benefit? 16
