As orders for ‘ammonia-ready’ ships accumulate, ClassNK’s work to overcome its crew safety challenge will be key role in realising the fuel’s potential as a contributor to maritime decarbonisation.

Latest published figures from Clarksons Research indicate that 25 ammonia-fueled ships were ordered during 2024¹.

Given that 50% of all 2024 ships ordered will burn alternatives to conventional fuels, ammonia’s contribution to a low CO₂ emission future, therefore, appears modest, compared to 390 fueled by LNG, 119 by methanol, 72 by LPG (and 12 by hydrogen), and 206 with battery/hybrid propulsion.
