Liquefied biogas (LBG) – also known as liquefied biomethane and bio-LNG – is a fossil-free and 100% renewable fuel that can reduce CO2 emissions over its life cycle by up to 90% compared to conventional fuel.
The use of LBG emits close to zero oxides of nitrogen (NOx) and sulfur oxides (SOx), and no particulate matter (PM), contributing to cleaner air especially for inhabitants living close to the sea and busy ports.
As a fuel, LBG is interchangeable with LNG, as they both consist mainly of methane (CH4). This means that the two gases can be mixed. Using both LNG and LBG is one of the concrete actions that will take us towards a low-carbon society of the future.
Gasum’s production and sourcing of LBG is steadily increasing to meet growing demand of customers. Currently LBG comes with a premium. The higher price is due to higher production and transportation costs and limited availability in the market.
Burning LBG releases only carbon dioxide (CO2) and water (H2O) into the air. Since the LBG is produced from biodegradable materials, the carbon dioxide is from sources that would anyway release CO2 in a natural combustion process. Thus, LBG is a sustainable and renewable product that does not add any new CO2 into the atmosphere.
LBG contributes towards the greenhouse gas emission (GHG) targets set by the global maritime industry. The vision of the International Maritime Organization (IMO) is to reduce annual maritime GHG emissions by at least 50% by 2050, when compared to 2008. Ultimately, the goal of IMO is to phase out GHG emissions completely during this century.
The feedstock from which biogas is manufactured varies from country to country. Gasum produces biogas in Finland from biodegradable waste generated by homes, retail outlets and industry and from municipal sewage sludge. Biogas produced by Gasum in Sweden is made from agricultural side streams, such as cereal straw and husks. Read more about biogas and Gasum’s network of biogas plants.
