Brooklyn-based Amogy has scored another first by modifying a 1957-vintage tug to run on liquid ammonia. The tug already had an electric drive system using diesel generators and electric motors. Amogy will replace the diesels by retrofitting a 1MW ammonia generator.
It will be using a cracking reactor to split ammonia into hydrogen and nitrogen, then running the hydrogen through a fuel cell to create electricity and feed the electric motors. This will create a zero-emission vessel.
Ammonia, which does not emit CO2 when used as a fuel, is expected to become a next-generation fuel because it has properties that are ideally suited for the hydrogen economy. Green ammonia, which is produced with renewable energy, results in zero greenhouse gas emissions from “well to wake.”
The tug is the latest ammonia-fuel-project undertaken by Amogy, which already rolled out the world’s first ammonia-fueled tractor, and the world’s first ammonia-fueled semi-truck.
