The EU’s 2014 Alternative Fuels Infrastructure Directive requires member states to build a comprehensive LNG infrastructure across European ports, thus paving the way for a large LNG market.
However, the study finds that LNG as marine fuel would deliver, at best, a 6 pct reduction in ship greenhouse gas emissions by 2050 compared to the replaced diesel.
The study considers four different scenarios showing a relative GHG emissions abatement ranging from 6 to 10%. 6% corresponds to LNG replacing marine gas oil (MGO), which is expected to become a more expensive fossil liquid fuel. On the other hand, the 10% corresponds to LNG replacing heavy fuel oil (HFO) or low-sulphur heavy fuel oil (LSHFO).
