1
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 RD

6
Synthetic Natural Gas (SNG) - Xinjiang Qinghua
Transport SNG in pipelines rather than coal on
trucks
  • 50 PJ corresponding to gt50 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

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

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
