engine for maritime shipping. It aims to specify and demonstrate an entire, marine-propulsion system that will pave the way for the first commercial order for an ammonia-fuelled vessel. MAN Energy Solutions will lead the consortium that also numbers: Eltronic FuelTech, the Danish fuel-system supplier; the Technical University of Denmark and DNV GL, the leading classification society. Development of the engine is scheduled for 2024.
As a marine fuel, ammonia has the potential to decarbonise the marine industry. The project aims to demonstrate – at full-scale – a large marine engine running on ammonia at MAN Energy Solutions’ test facility, Research Centre Copenhagen. The project comprises three main stages:
1. Concept development and initial design of an ammonia engine.
2. Design of an ammonia fuel-supply system.
3. Full-scale testing.
Ammonia is interesting because it is an energy carrier that does not contain carbon, and whose combustion therefore does not produce CO2. Similarly, its production from electricity doesn’t require a carbon-based source, while its production is infinitely scalable.
Since large quantities of ammonia are already transported around the world, it is a well-established commodity with some 120 ports globally currently involved in its import/export and some with storage facilities. Thus, using ammonia to power ships would be a natural step with infrastructure already in place.
The AEngine project is adopting an interdisciplinary approach to cover the implications of using ammonia as fuel aboard a ship, as evidenced by its participants.
