  1. Claus Friis Pedersen clfp@topsoe.dk Grøn gas gennem metanisering

  2. Vehicle to grid (V2G) is the future!

  3. An integrated energy infrastructure CH4 + CO2 + 4H2 2CH4 + 2 H2O

  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 SOFC SOEC H2O H2 H2 H2O H2 + O2- → H2O + 2e- H2O + 2e- → H2 + O2- O2- O2- ½O2 + 2e- → O2- O2- → 2e- +½O2 ½O2 ½O2

  8. Exergy Flows

  9. Biogas upgrade value proposition # 1 CH4 + 30-40% CO2 Biogas BioGas CH4 40 PJ Biogas Upgrade CO2 ”Electro-gas” CH4, 27 PJ H2 Electrolysis Fuel synthesis

  10. Biogas upgrade value proposition # 2

  11. Pre studies Metan samfundet SOEC biogas upgrade

  12. The business case (w. 5% interest) 2035 91% Electrolysis 2020 100% Electrolysis Plant size: 75 mio Nm3 biogas/year Mio DKK

  13. Pilot test at Foulum – 5 Nm3/h CH4 + CO2 + 4H2 2CH4 + 2 H2O

  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
