Navigating the future-fuel outlook for large merchant marine vessels

Abstract

The presentation outlines the rapid transition of the global shipping sector toward cleaner fuels as the industry grows by an estimated 60% over the next three decades, driven by globalization and rising living standards but tempered by geopolitical and regional uncertainties. MAN Energy Solutions’ dual‑fuel engines are becoming central to this shift, with more than half of recent vessel orders and an expected 85% of two‑stroke newbuilds by 2030 adopting dual‑fuel capability across methane, methanol, ethane, LPG, and conventional fuels. Market trends show tankers and container ships dominating dual‑fuel adoption, while long‑term forecasts project a 2050 fuel mix increasingly led by ammonia, methanol, and methane as traditional fuel oil declines. Ammonia is highlighted as a major future marine fuel, with development focused on mitigating nitrous oxide emissions—an essential step for meeting tightening global decarbonization regulations.
