Danish investment entity Innovation Fund Denmark is behind a new consortium that will develop a two-stroke, ammonia-fuelled marine engine, with the intention of demonstrating a complete propulsion system that will pave the way for the first commercial order for an ammonia-fuelled vessel.

MAN Energy Solutions, as project coordinator, will lead the consortium, other partners being fuel system supplier Eltronic FuelTech, Technical University of Denmark (DTU) and classification society DNV GL. The aim is to demonstrate a working engine by 2024.

MAN Energy Solutions VP Head of R&D, Two-Stroke, Brian Østergaard Sørensen said: “MAN Energy Solutions has spoken in favour of a maritime energy transition in shipping for many years now and we understand the need to work with a wide group of industry partners to develop sustainable solutions. Ammonia is a fuel with a lot of potential and yet another, important step towards decarbonising the marine market. We already have a convincing track-record in developing engines running on alternative fuels – having developed the world’s first 2-stroke engines driven respectively by methanol, ethane and LPG – and have great expectations for this project.”

Ammonia fuel is seen as a potential route to decarbonisation of the marine industry. The project aims to demonstrate – at full-scale – a large marine engine running on ammonia at MAN Energy Solutions’ test facility (pictured) in 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 an energy carrier that does not contain carbon, and whose combustion therefore does not produce CO2. Similarly, its production from electricity does not 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 ship fuel.

I see a shared interest in ammonia combustion. Still not as much is known about it as is te case for natural gas. I like to offer you a possibility for jointly filling knowledge gaps on it on flame stabilisation, best NOx reduction methods and fast but accurate CFD. In this context TU/e could be a good partner for doing research. This also because we are partner in the EU Horizon 2020 project FLEXnCONFU about the use of H2, NH3 mixtures in power generation. We think that especially for optimising specific designs fast and accurate reactive CFD would be a real asset with large added value.
