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

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
