Wärtsilä has introduced the marine sector’s first commercially available 4-stroke engine-based solution for ammonia as a fuel. The ammonia solution is now commercially available as part of the Wärtsilä 25 engine platform, which was launched in September 2022.

Viridis Bulk Carriers, the World’s first zero emission shipping company, is intended to be the first shipowner to benefit from the new ammonia solution. The company is a partnership between Amon Maritime, Mosvolds Rederi and Navigare Logistics. Earlier this month, Wärtsilä and Viridis Bulk Carriers signed a Letter of Intent for the Wärtsilä 25 ammonia engine solution, targeting to sign a commercial contract in early 2024. Viridis Bulk Carriers is bringing a ‘green game changer’ to the European short sea bulk market, planning a carbon free transportation service based on a series of ammonia-powered newbuild vessels.
