Connection to the natural gas grid is not always possible. Bio-LNG or liquid biomethane is the solution where there are logistical constraints.
Liquefied biomethane, in fact, is not only easily transportable to its point of use but, thanks to its density three times higher than that of compressed natural gas, it ensures greater efficiency when used as fuel.
The main difference between bio-CNG and bio-LNG (i.e. between compressed biomethane and liquefied biomethane) lies precisely in the latter’s use mainly in heavy vehicles, where autonomy almost doubles compared with the gaseous form, thus constituting the ideal alternative to diesel for long distances.
What is the meaning of liquefaction? The liquefaction of biomethane is a complex process, which consists in cooling and compressing the gaseous biomethane at very low temperatures. The transformation is such that the liquefaction of biomethane is very advantageous compared with other gases: with 600 litres of gaseous biomethane, only one litre of liquid biomethane is obtained.
An AB biomethane liquefaction plant is a containerised modular solution based on an integrated cryogenic process, divided into three phases: treatment, liquefaction and storage. An efficient system that can also be combined with other AB solutions to create a totally sustainable energy system.
Liquid biomethane has an easy production and delivery programmability
Liquid biomethane is the solution where connection to the gas network is not possible. In fact, it is easily transportable with cryogenic tankers up to its point of use
Bio-LNG is a valid alternative to diesel for heavy transport, as it guarantees greater autonomy in long-haul travel
