Up to 20 new large ammonia carriers need to be ordered now and built every year to 2030 to meet the potential demand for transporting green fuels to meet global climate goals, a report claims.

The report — named Shipping’s Role in the Global Energy Transition — said shipping will be crucial in transporting green fuels, but there is a yawning gap between announced government-led projects and what is required.

The world needs 50m to 150m tonnes of low-carbon hydrogen by 2030 but current projects will only produce 24m tonnes by that point, said the report from the Tyndall Centre at the University of Manchester in the UK, which was released for Energy Day at the COP27 climate crisis talks in Egypt.
