Maritime ammonia: fuel cell propulsion systems, car carriers & bunkering in Germany

In maritime ammonia updates this week:

  • Alma Clean Power’s containerised SOFC system design has been granted AiP by DNV. A 2 MW, ammonia-fed system will be used to retrofit the Viking Energy vessel as part of the ShipFC project.
  • Grimaldi Group has increased its order for ammonia-ready car carriers to fifteen. China Merchants Heavy Industries will construct the 9,000 car equivalent units design at Jiangsu shipyards, delivering the first vessels in 2025.
  • Mabanaft and Hapag-Lloyd will explore the supply of ammonia bunker fuel to Hapag’s vessels at the Port of Hamburg (Germany), and the Port of Houston (USA).
  • and the German Federal Ministry for Economic Affairs and Climate Action will fund the construction of three, future-proof LNG bunker vessels, which are designed to be upgraded to handle ammonia fuel.

Wärtsilä launches new multi-fuel maritime engine

Wärtsilä has just launched its medium-speed, 4-stroke, Wärtsilä 25 engine, intended to be the first Wärtsilä engine to run on ammonia fuel. From 2023 a technology upgrade will be commercially available to allow the engine to run on alternative fuels like ammonia, with a fully-compliant NOx abatement system already available when running on fossil-based fuels. At the recent Australia conference, MAN ES reported that their two-stroke ammonia engine will be commercially available in 2024, with testing to commence next year.
