The cleanest marine fuel available


If we are to fight climate change, emissions from the use of conventional fuels such as heavy fuel oil in maritime transport need to be reduced. Rapidly becoming more common as a cost-effective alternative, liquefied natural gas (LNG) is the cleanest marine fuel available. Compared with heavy fuel oil, LNG has significantly lower CO2 emissions, and almost nonexistent particle emissions.

LNG is a safe and proven technology that offers higher energy content and lower operational and maintenance costs. It is suitable for all vessel types, including ferries, passenger ships, tankers, bulk carriers, supply and containerships.

As a premium provider of LNG, Gasum is a trustworthy partner for both experienced buyers and for customers that are switching from conventional fuels to LNG. Our wide variety of sustainable yet efficient services and solutions support our customers in optimising their operations for a more sustainable future.

Decarbonization of the maritime industry 

Maritime traffic generates 3 percent of the world’s total greenhouse gas emissions such as carbon dioxide. This contributes to global warming and extreme weather conditions. CO2 is emitted by ships using petroleum-based fuels to power main and auxiliary engines. Through the International Maritime Organization (IMO) the world’s shipping industry is constantly working to reduce CO2 emissions. 

LNG as a marine fuel meets all the current and forthcoming IMO and EU regulations. Switching to LNG means complete removal of Sox and particles, and reduction of Nox emissions of up to 85 percent. LNG reduces CO2 emissions by at least 20 percent.

As a fuel, LNG is interchangeable with renewable LBG (liquefied biogas), as they both consist mainly of methane. 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.
