LNG Gains Momentum as Transitional Fuel for Maritime Industry

In Finland, Wärtsilä reports as global emissions regulations tighten, the maritime industry is increasingly adopting liquefied natural gas (LNG) as a cleaner alternative to traditional marine fuels with over 2,400 vessels operating on LNG. LNG reduces greenhouse gas emissions by 20-30% and virtually eliminates sulfur oxides, positioning it as a pivotal transitional fuel in the industry’s shift toward decarbonization.  While LNG is still a fossil fuel, the development of bioLNG from organic waste offers a more sustainable option, further reducing the carbon footprint. with more infrastructure expected to expand its use.

LNG, which is primarily methane, is transformed into a liquid at -162°C, making it more manageable for transport and storage. It’s widely used for ship propulsion and auxiliary power, supported by a growing network of LNG bunkering facilities worldwide. Despite its benefits, challenges such as the need for specialized handling equipment and potential methane slip — where unburned methane escapes into the atmosphere — persist. However, advancements in engine technology have significantly mitigated these issues.

Continued adoption has established LNG’s crucial role in paving the way for future zero-carbon fuels in line with the International Maritime Organization’s goals to halve greenhouse gas emissions by 2050.
