About the project

In 2018, the International Maritime Organization, IMO, adopted an initial strategy to reduce and later phase out greenhouse gases from the shipping sector. Fossil fuel phase-out will be required in order to meet the long-term targets. Liquefied natural gas, LNG, has been discussed as a step on the road. It is a popular alternative for environmental and cost reasons. On one hand, LNG produces lower CO2 emissions per energy unit than fossil oil, but on the other, LNG engines have been shown to allow for methane to be emitted to the air in large amounts. This is referred to as a methane slip. The GHG impact from the methane slip could be reduced by replacing LNG with LBG, liquefied biogas.

This project provides knowledge and elaborates on the conditions for providing shipping with LBG, which is an environmentally, economically and socially sustainable renewable fuel alternative. The project will produce data on how much LBG can be produced, reqiured conditions and techniques (including Power to gas, P2G), and which cost levels that are accepted by shipping companies and transport buyers in the short and long term. Expected policy instruments will also be considered in the project.
