Is liquid bio-gas part of the solution to greenhouse gas emissions from shipping?
Research Project , 2020 – 2021

In 2018, 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. LNG has been discussed as a step on the road and is popular in shipping for environmental and cost reasons. LNG produces lower emissions of CO2 per energy unit than fossil oil, but LNG is unfortunately not better than oil since the ship's LNG engines have been shown to emit large amounts of methane (so-called methane slip). The GHG impact can be reduced by replacing LNG with LBG. The project provides knowledge and conditions for providing shipping with LBG, which is a possible, environmentally, economically and socially sustainable renewable fuel. The project will produce data on how much LBG can be produced, the conditions and techniques (including P2G) required, costs accepted by shipping companies and transport buyers in the short / long term. Considering expected policy instruments.
