Finland – A powerful group of shipping stakeholders is working to develop demonstrators for ammonia-fueled two-stroke and four-stroke marine engines.
The Ammonia 2-4 project aims to develop viable ammonia fuel concepts. Wärtsilä is leading the project, which includes naval architects C-Job, classification society DNV, ship owner MSC, and Italy’s National Research Council (CNR). The European Union has provided funding of €10 million through the Horizon Europe research funding initiative.
Lab-based demonstrator
By 2025, the project will have produced a lab-based demonstrator for the four-stroke ammonia engine and a lab-based test engine for the two-stroke version, as well as a vessel retrofit for the two-stroke version. The Ammonia 2-4 project will advance engine concepts as well as develop concepts for fuel handling and safety, as well as contribute to the development of an ammonia regulatory framework.
