Some biofuels, like biogas from landfills—or synthetic methane—are attractive for use in vehicles as they have a potentially low energy cost to produce. They also have lower criteria emissions, of the sort that affect human health and cause smog. These engines should easily be cross-compatible with those using compressed natural gas... EU engine-tech project could help gas catch up with gasoline
