1 Confidential Claus Friis Pedersen Grøn gas gennem metanisering

2 Vehicle to grid (V2G) is the future!

3 An integrated energy infrastructure CH 4 + CO 2 + 4H 2 2CH H 2 O

4 The right factors for biogas upgrading

5 Haldor Topsøe group (2011) Catalyst and engineering for  Fertilizers  Refineries  The environmental sector  Synthetic fuels  Turnover: DKK 4.4 billion  Result: DKK 397 MM  2091 employees  250 employees in R&D

6 Synthetic Natural Gas (SNG) - Xinjiang Qinghua  50 PJ corresponding to >50% of the total Danish Natural gas consumption  5 PJ gasified biomass SNG plants are projected  0.1 PJ would be a large biogas methanation unit Transport SNG in pipelines rather than coal on trucks

7 Fuel Cell and Electrolyser ½O 2 H2H2 H2OH2O H 2 O + 2e - → H 2 + O 2- O 2- O 2- → 2e - +½O 2 H 2 + O 2- → H 2 O + 2e - O 2- ½O 2 + 2e - → O 2- SOFC SOEC H2H2 H2OH2O

8 Exergy Flows

9 Biogas upgrade value proposition # 1 Biogas CH % CO 2 H2H2 Electrolysis BioGas CH 4 40 PJ ”Electro-gas” CH 4, 27 PJ Biogas Upgrade CO 2 Fuel synthesis

10 Biogas upgrade value proposition # 2

11 Pre studies Metan samfundet SOEC biogas upgrade

12 The business case (w. 5% interest) % Electrolysis % Electrolysis Mio DKK Plant size: 75 mio Nm3 biogas/year

13 Pilot test at Foulum – 5 Nm 3 /h CH 4 + CO 2 + 4H 2 2CH H 2 O

14 Summary  Electrolysis based biogas upgrade has the potential to: –Store electricity as fuel –Increase the biogas production  The business case is interesting but many aspects are still uncertain  A pilot scale field trial is planned for 2015
