Can biogas be used as a source of compressed gas for vehicles?
There is no doubt that methane is an excellent fuel and that very low emissions can be achieved with it. The IANGV is dedicated to furthering its use. So we all agree that it would be good to see the wider use of natural gas (NG) as a fuel, from the point of view of lower emissions, better resource use and higher engine efficiency. But there are many other factors to be taken into account. First the storage issue: this requires that gas be compressed to high pressures (or liquefied) for storage – this requires a network of costly refuelling stations. And the on-vehicle storage requirements are a significant weight and cost factor. It is clear that the early development of networks of stations are best concentrated on areas where heavy duty vehicles – buses and other service vehicles – are operating. We certainly support the use of biogas, which in its original form will contain a high proportion of CO2 which must be removed if storage costs are to be minimised and high engine performan
