Ships will run on ammonia and hydrogen ‘within three to eight years’


Ammonia and hydrogen onboard fuel technologies will be available for the shipping industry within three to eight years, according to DNV’s Maritime Forecast to 2050 report.

The sixth edition report, a year in the making, forecasts 2-stroke and 4-stroke engine technologies on parallel paths for ammonia, enabling uptake in deep sea and regional short sea shipping, with the latter expected to be instrumental for maturing hydrogen technology. 

Consequently, the development of fuel cells and 4-stroke engines is ahead of other hydrogen energy converters, the report finds. 

Despite the strong interest in ammonia as fuel, it is currently restricted by immature converter technologies – and time is not on the industry’s side as it strives to decarbonise.
