Swiss engine designer WinGD says its engines will be able to run on methanol from 2024 and ammonia from 2025.
WinGD said the ability to use the zero-carbon or carbon-neutral fuels will be possible in both its core diesel-fueled X engines and dual-fuel X-DF engines.
It will give ship operators flexibility in how they reduce emissions and means they can invest in vessels ready to use ammonia and methanol, the company added.
