>> Biogas can be compressed, the same way as natural gas is compressed to CNG, and used to power motor vehicles.

>> In the United Kingdom, for example, biogas is estimated to have the potential to replace around 17% of vehicle fuel.

>>It qualifies for renewable energy subsidies in some parts of the world. Biogas can be cleaned and upgraded to natural gas standards,

>> when it becomes bio-methane. Biogas is considered to be a renewable resource because its production-and-use cycle is continuous, and it generates no net carbon dioxide.

>>As the organic material grows, it is converted and used. It then regrows in a continually repeating cycle.

>> From a carbon perspective, as much carbon dioxide is absorbed from the atmosphere in the growth of the primary bio-resource as is released, when the material is ultimately converted to energy.
