Picking bunker winners: the mono-fuel / dual-fuel duel
This week, DNV GL published its annual Maritime Forecast to 2050, concluding that “e-ammonia, blue ammonia and bio-methanol are the most promising carbon-neutral fuels in the long run.” DNV GL’s assumptions that determine this long run, however, suggest a significant mid-term reliance on fossil LNG. This risks locking the industry into a long-term emissions trajectory incompatible with the IMO’s 2050 GHG targets, in part because of significant fuel supply and infrastructure investments. These investments could become more ‘sticky’ than expected. A host of alternative opinions have been published in the days before and after DNV GL published its report. These suggest that, for ammonia, the long run could begin this decade. Among others, MAN ES has announced that its ammonia engine will be available for retrofits by 2025.
