Context and challenges

A European Directive introduced in 2012 uses figures from the International Maritime Organization (IMO) as the basis for setting new maximum sulfur content thresholds for marine fuels. These thresholds will go global in 2020 or 2025, but nitrogen oxide emissions must be cut from 2016 onwards. The use of Liquefied Natural Gas (LNG) as a fuel reduces polluting gas and greenhouse gas emissions considerably in both maritime and road transportation applications.


The solution

When cooled to -162°C, the gas becomes a liquid occupying 600 times less space, and can be used as a fuel that produces less pollution and has a lower environmental impact than diesel or gasoline for maritime and road transportation.

It is also more efficient: engines running on LNG produce more power and require less maintenance. Additionally, LNG improves comfort levels, because engines running on this fuel are quieter.

ENGIE has control over every link in the Liquefied Natural Gas production chain, from exploration to distribution, making it perfectly placed to respond to growing demand from the transportation industry. The Group has signed a framework agreement with Mitsubishi Corporation and NYK covering the global market for LNG fuel.


In maritime applications, the use of LNG cuts sulfur emissions by 90%, particulates by 95%, nitrogen oxides (NOx) by 80% and CO2 by 15-20%, compared with diesel fuel. LNG enables compliance with new directives introducing maximum thresholds for the sulfur content of marine fuels based on figures from the International Maritime Organization (IMO) and incorporated into a European Directive adopted by the European Parliament.


Key figures

Lower emissions than diesel fuel for Maritime transportation:

  • 90% less sulfur
  • 95% fewer particulates
  • 80% lower nitrogen oxides (NOx)
  • 15-20% less CO2

The volume occupied by liquefied natural gas, compared with its gaseous state: 600 times less.
