OTHER APPLICATIONS OF BIOGAS
Biogas is also successfully compressed for use as an
alternative transportation fuel in light- and heavy-duty vehicles.
To obtain usable methane, the biogas is scrubbed of its carbon
dioxide, hydrogen sulfide, and water. After scrubbing, the
technique of fueling with biogas is basically the same as that
used for compressed natural gas (CNG) vehicles. It is estimated
that worldwide around one million vehicles are now using CNG
as a transportation fuel.
