Biogas, chimera or reality

Biogas is a combustible gas that is generated naturally during the process of degradation of organic matter. Biogas production is a useful means of treating biodegradable waste. Biogas consists of a proportion between 50% and 70% in volume of methane, which, on the other hand, is the main component of natural gas. Therefore, if the biogas is adequately purified, it can be used for the transport and mobility sector as if it were natural gas.

This fact may be a primary factor for the subsistence and growth of the market for natural gas vehicular (NGV) in its two versions: compressed (CNG) and liquefied (LNG). The main advantage of using natural gas in the transport sector is the reduction of CO2 emissions into the atmosphere. According to data reported by the NGVA Europe association (, this sector represents a third of total emissions in Europe and is the main cause of air pollution in cities. Gas vehicles, which currently circulate on European roads, will contribute this year to a 20% decrease in emissions compared to those emitted by the same vehicles powered by traditional fuels. If, in addition, we consider that 17% of the gas currently used in Europe for the mobility sector comes from biogas, the decrease in emissions will reach 35%.

Another basic aspect, which also favours this idea, is that the infrastructure associated with the storage and distribution of this type of gas (including the dispenser itself) is fully compatible with that used for NGV.

Therefore, a promising future is foreseen for the use of biogas for mobility and transport, which will be possible thanks to the increasing presence of this type of dispensers at service stations. Dispensers that, when the delivered gas comes from biogas, delivers BioNGV (BioCNG or BioLNG).

Clear example of the interest aroused by the use of biogas in other European countries such as France, is the first installation of a Cetil dispenser carried out by Prodeval for BioCNG delivering. The following article explains it in detail:
