6. Synthetic Natural Gas (SNG) - Xinjiang Qinghua
Transport SNG in pipelines rather than coal on trucks
The Xinjiang Qinghua coal-based SNG plant will be the largest single-train SNG plant in the world.
It will produce Nm3/h or 1,4 billion Nm3/year.
This has been facilitated by a highly heat-resistant catalyst, which I will come back to.
The contract was awarded in September 2009, and completion is expected already this year.
In this case, Topsøe provided both (read)
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

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
