Fossil Fuels Are 40% of Freight Shipping Tonnage, but Half Its Fuel Use

- Fossil fuels represent about 40% of maritime tonnage but account for half of freight energy due to their long-haul bulk transport.
- The decline in fossil fuel cargoes reduces transport work and fuel demand, meaning not all current shipping fuel needs a direct replacement.
- Electrification is viable for segments like ferries, short-sea routes, and coastal shipping, which have regular routes and charging opportunities.
- Operational efficiencies (e.g., slow steaming, wind assistance) further reduce fuel demand for remaining fuel-burning vessels.
- Residual liquid fuels (e.g., biofuels) should only target voyages still needing energy-dense fuels after efficiency and electrification gains.
- Ammonia and hydrogen face challenges like cost and safety, while synthetic fuels have high energy conversion losses.
- Shipping decarbonization requires focusing on reduced fuel demand from cargo shifts and electrification, not just alternative fuel substitution.
