1 Workshop Putting Science into Standards: Power-to-Hydrogen and HCNG Keynote 1: Power to Gas potential & requirements P. Röttgen E.ON Innovation Center Energy Storage EASE Vice President 1

2 EASE is the European voice of the energy storage community advocates the role of energy storage as an indispensable instrument for the energy system. supports a sustainable, flexible and stable energy system. shares and disseminates information. Strategic objectives 1 Promotion of the role and benefits of energy storage 2 Fair market design for energy storage 3 Promotion of funding for energy storage (mainly RD&D) 2

5 Upcoming Event Energy Storage Global Conference 2014 Registration open Paris - Cercle National des Armées 19 th to 21 st November

6 Reasons for energy storage variable generation wind power, solar power Fluctuating demand households, industry Sometimes deficit in generation Sometimes grid congestion 6

7 Flexibility from Generation Grids Power Storage Wind/Solar-to-Power Power-to-Power Gas-to-Power/Heat Gas Heat Power-to-Gas Coal-to-Power/Heat Power-to-Heat Demand Residential Mobility SME Industry 7

8 Energy storage renders various services Applications in the energy market Generation Trading & Optimization Transmission Distribution Sales End Customer Conventional plant operators Wind park operators Energy suppliers Trading companies Grid operators Wholesalers Retailers Industry Households PV park operators Balancing market and interfaces to other markets, especially mobility 8

9 Minimum required power (MW) Flexibility demand needs different storage technologies needed & already today available storage technologies for Generation Trading/Grids Customer >200 <200 <30 Large-scale Slow-reaction <5 <2 Fast-reaction Other small-scale <1 0 0 <15 sec <30 sec <1 min <1.5 min <5 min <10 min <30 min >30 min High-frequency applications Required response time Low-frequency applications 9

10 Comparing the energy content Vessel, t Hard coal, 540 GWh el Period over which a 800 MW 35 d generation plant can be fueled Gas Storage: 260 GWh 17 d Hydrogen storage: 84 GWh 5 d PSP Waldeck: total 4,3 GWh 6 h CAES Huntorf 0,9 GWh 1,4 h Assumptions: for hydrogen and UGS respectively small size caverns of m 3 volume (=Huntorf), Efficiency gas generation: 0,6 10

11 Comparison of 1 GW (1000 MW) transport capacity corresponding to the power of a large scale power plant or peak power of 200 wind turbines Transmission grid Pipeline (0,6 m of diameter) 11

12 Power-to-Gas connects markets Certificate Power Electrolysis Power Grid H 2 Certificate Gas CH 4,Bio CO 2 SNG 3 Power Heating Mobility Industry Power Heating Mobility Industry Renewable hydrogen 12

13 Example: Power-to-Gas for Refineries today tomorrow Fossil Energy Natural CH 4 gas Renewable Energy Biomass H 2 Ethanol Hydrogen Ethanol Oil Refinery E5 / E10 Hydrogen green Hydrogen H 2 CH 4 H 2 Fossil Energy Natural gas Renewable Energy Power Certificate Product Certificate Storage effect = Integration of renewables 13

14 Important for Power-to-Gas in the Mobility sector Recognize green hydrogen as an advanced biofuel The (indirect) land use for Green Hydrogen is very small (ILUC) Green Hydrogen is uniquely sustainable Rapid integration of Green Hydrogen into the mobility sector is possible Green Hydrogen and traditional biofuels complement each other Recognize all use cases for green hydrogen Green Hydrogen can be used in fuel cell vehicles, natural gas vehicals (with methanation) and directly in the refinery process All those use cases have to be equally recognized Implement a high quota for advanced biofuels Currently 5%, 3% and 0.5% quotas for Advanced Biofuels are discussed for mobility A higher quota for Advanced Biofuels ensures more sustainable fuels in Europe 14

15 Example: Power-to-Gas for Industry today tomorrow Fossil Energy Power Fossil Energy Natural gas Fossil Energy Natural gas Power Renewable Energy Chem. Industry Certificate Hydrogen H 2 H 2 Green hydrogen Product Storage effect = Integration of renewables 15

16 Example: Power-to-Gas projects in Germany Source: DVGW 16

17 Example: Power to Gas pilot "WindGas Falkenhagen" Key Parameters Power: 2 MW el Hydrogen production: 360 m³/h Fed into the local gas grid (ONTRAS Gastransport) Start of operation 08/28/2013 Owner is E.ON Gas Storage Goals Demonstration of the process chain Optimize operational concept (fluctuating power from wind vs. changing gas feed) Gain experience in technology, costs, consenting In cooperation with 17

18 Example: Power to Gas pilot "WindGas Falkenhagen" 18

19 Example: WindGas Hamburg Key Parameters Public funding from BMVDI Power: 1 MW el (stack) Hydrogen production: 265 m³/h Fed into the local gas grid Planned start of operation: 2015 Goals Utilization of high efficient Proton Exchange Membrane electrolysis (PEM) Funding & Partners Demonstration within E.ON infrastructure Business development 19
