A recent study by WinGD, focusing on cost-effective net-zero emissions for ship operators, concludes that converting vessels to run on Liquefied Natural Gas (LNG) offers the most rapid financial return. While ammonia and bio-methanol retrofits promise more substantial emissions reductions, their payback periods are considerably longer. The analysis also found that, under the modeled assumptions, all three alternative fuel retrofit options—LNG, ammonia, and bio-methanol—outperform the continued operation on Very Low Sulphur Fuel Oil (VLSFO) in terms of both cost-effectiveness and emissions reduction over the vessel's operational lifetime.
However, the report strongly emphasizes the need for additional policy support to enhance the economic viability of these retrofit projects. Such support is deemed essential to ensure that the maritime industry can meet its ambitious decarbonization targets.
For freight forwarders and operations managers, this study provides insights into the evolving landscape of sustainable shipping. While LNG offers a more immediate financial incentive for carriers to adopt cleaner fuels, the long-term potential of ammonia and bio-methanol for deeper decarbonization remains significant. The call for policy support suggests that regulatory frameworks and incentives will play a critical role in accelerating the transition, potentially influencing future bunker prices and the availability of green shipping options. Forwarders should monitor policy developments as they could impact carrier choices, operational costs, and the availability of low-emission services.
