Fossil fuels account for 40% of shipping tonnage but half of maritime fuel use, reshaping the alternative fuel debate
By
Michael Barnard
Summary
The article argues that the maritime shipping industry's fuel transition debate is misguided because it focuses on replacing current bunker fuel volumes without accounting for the fact that fossil fuels make up about 40% of shipping tonnage but consume roughly half of maritime fuel energy. As the world transitions away from fossil fuels, demand for shipping these fuels will drop significantly, reducing overall maritime fuel needs. This changes the equation for what alternative fuels (ammonia, methanol, hydrogen, etc.) are actually required. The article advocates for first shrinking the fuel pool through reduced fossil fuel shipping demand, then strategically deploying electrons and scarce low-carbon fuels only where they are most needed.

· 3 pulledMaritime fuel debates usually start with the wrong object. They look at today's bunker fuel demand, line up replacement molecules, and ask whether ammonia, methanol, hydrogen, LNG, biofuels, or synthetic fuels can scale far enough to replace it.
Fossil fuels are about 40% of maritime tonnage but roughly half of freight energy, which changes the shipping fuel transition.
Shipping's transition starts by shrinking the fuel pool, then using electrons and scarce liquids only where they fit.
