LBG is the abbreviation for Liquefied Bio Gas, which is also known as liquid biogas in Dutch (comparable to lng). One also speaks of LBM (Liquefied biomethane).
Unlike lng, which is produced from natural gas, methane in LBG is derived from biomass. A source of this gas is, for example, fertilizer fermentation. Another source is waste gas, which is released by a landfill.
The energy content of 1m (at normal temperature and pressure) biogas, containing 97% methane, is 9.67 kWh, which corresponds to 1.1 liters of crude oil.
In Sweden, it is particularly important to make this technology operational, as well as plans for a gas station where LBG trucks, which are currently in use (compare the natural gas bus), can be provided. In this way, the country hopes to become less dependent on imported fossil fuels. Disadvantages
Although the raw material is basically renewable, its large-scale production, which is required to replace a substantial part of the fossil fuel, must be made of primary biomass, not waste. However, this leads to the need for very large areas of plantations with energy crops. Of course, it also takes a lot of energy to bring and maintain the gas at the desired, very low temperature of - 162 ° C.
