Glossary of Fuels

This section provides information on the acronyms used in this website.

 

CNG

Compressed Natural Gas. Composed mostly of the compound methane. Currently, the majority of methane available is a fossil fuel. However, new production options such as anaerobic digestion of organic waste are providing routes to renewable methane or bio-methane. This is also known as bio-gas. 



CBG

Compressed Bio-Gas. Chemically identical to methane this is simply compressed bio-methane / bio-gas.



LNG

Liquefied Natural Gas. This is simply methane in its liquid state. LNG is gaining popularity as a transport fuel since the vehicle can store in the same space a larger quantity of methane when it is in its liquid state than when it is stored as a gas.



LBG

Liquefied Bio-Gas. This is simply liquefied methane albeit derived from renewable sources. 



LPG

Liquefied Petroleum Gas. This is a mixture of liquefied propane and liquefied butane which are gases at room temperature and standard atmospheric pressure. As above, storage as liquid allows a larger quantity of this mixture to be stored within the same space on a vehicle than if the mixture were a gas. New techniques are now providing routes to renewable propane or bio-propane. In the US, gaseous and liquefied propane are available as transport fuels.
