December 18, 2024. Industry coalition SEA-LNG analysis shows that LNG dual-fueled vessels provide the lowest compliance cost for meeting EU and IMO decarbonization regulations.
Using Z-Joule’s POOL.FM, SEA-LNG has undertaken analysis based on a modelled mid-sized, 14,000 TEU container vessel. This analysis is in the form of both a single vessel and also an eight-vessel fleet operating the Rotterdam – Singapore trade route over the period 2025 to 2040.
The analysis focuses on the LNG, methanol, and ammonia fuel pathways and compares their compliance costs against the default of using VLSFO (very low sulphur fuel oil). The analysis uses the specifications for main and auxiliary engines published by the main marine engine manufacturers MAN ESWärtsilä and WinDG.
The study indicates that LNG, methanol, and ammonia dual-fuel engine technologies can reduce compliance costs compared with VLSFO, with LNG dual-fuel vessels providing a significantly lower cost compliance solution. The basis for this is that the LNG pathway offers immediate greenhouse gas reductions now and in the future compared with the other fuel choices. The use of LNG also dramatically reduces SOx, NOx and Particulate Matter (PM) thereby avoiding the use of relatively expensive MGO (marine gas oil) for ECA (Emission Control Area) compliance.
In terms of fleet operations, for an eight-vessel fleet with two alternatively fuelled “balancing vessels,” the overall cost of compliance with LNG will be between $5 million and $17 million per annum lower than other alternative fuels such as methanol and ammonia. Further, as FuelEU Maritime is implemented from 2025 onwards, fleet operators using ammonia and methanol dual-fuel vessels are likely to need significant quantities of expensive green fuels, in an effort to avoid very high penalty charges.
