Air Liquide Skagerak offers biogas and natural gas
What is biogas?
Biogas production process
Biogas arises from the decomposition of new biological material, such as animal manure, sewage sludge and food waste, without the supply of oxygen. The gas is odorless, colorless, and non-corrosive.
Upgraded to vehicle quality, biogas consists of approximately 98% methane (CH 4).
Contributing to a more circular economy
Biogas is produced from biodegradable waste originating from agriculture, the food-processing industry,and garden waste, which is collected locally then processed in nearby biogas plants.
Biogas can then be distributed and used as fuel, providing a renewable source of energy for local industries and transport infrastructures. Nothing is wasted: residues from the biogas production become fertilizers, reducing the use of artificial products.
The biogas at Greve
Air Liquide Skagerak markets and distributes all biogas from the Greve plant, first and foremost to the transport sector in Vestfold and Grenland.
Liquified or compressed biogas for different uses
Biogas can be stored in two ways depending on its final use.
LBG: Liquified Biogas is the term for liquified, cooled biogas. The gas is condensed to liquid by cooling to minus 162 degrees celsius. Easily and safely transportable, LBG is a reliable fuel solution for trucks, buses, and more.
CBG: Compressed Biogas. This is biogas compressed to 200-250 bar pressure. CGB is used to supply stations for captive light vehicle fleets, cars, semi-trailer trucks, vans or buses. CNG is in a gaseous state, stored in bundles.
A versatile energy source
Natural gas is a high-performance and extremely flexible fuel that can be used for virtually every imaginable energy purpose. Odorless, colorless and non-toxic, it is also the cleanest-burning hydrocarbon and can be used in combination with biogas to further reduce carbon emissions.
Natural gas processing
CNG or compressed natural gas is primarily used in vehicles. The gas is compressed to at least 200 bar pressure.
LNG or liquified natural gas is liquefied, refrigerated natural gas. The gas must be cooled to approximately minus 162° celsius to remain liquid at normal pressure.
