A new report says that a mixture of bio-gas and synthetic natural gas could play a more effective role in cutting transport carbon emissions.  The snappily-named North East Process Industry Cluster (or Nepic), Centrica and the National Grid commissioned a study to look at the use of Bio-SNG.  This suggests that "green natural gas", a mix of bio-gas and SNG might be delivered via the gas grid for both transport and heating use.  The gas uses methane from "sustainable" volumes of biomass mixed with synthetic or substitute natural gas, sometimes produced from coal or lignite.
