The shipping sector has increased its use of biogas
The shipping sector has increased its use of gas as fuel in recent years. A 2017 review of newly ordered vessels with links to Sweden showed that half of all new vessels were built to run on gas.
Although mainly liquid natural gas is being used, biogas can easily be blended with natural gas, or can replace it entirely. This trend has its origin in the sector’s environmental ambitions and tough new sulfur emissions standards for the Baltic Sea. According to a recent report from the Swedish Environmental Protection Agency, CO2 emissions from Swedish shipping decreased 27 per cent in 2019 largely due to the switch from oil-based fuels to natural gas.
Neither natural gas nor biogas give rise to sulfur emissions. Carbon dioxide emissions can be reduced by around 30 per cent using natural gas instead of heavy oil, and by a full 120 per cent using biogas. Supplying the shipping sector’s needs, however, requires large quantities of gas. As the supply of LBG increases, several shipping companies are ordering gas-powered vessels. And as more and more vessels are powered by gas, the need for biogas (LBG) also increases dramatically.
