MAN Energy Solutions to Lead New Ammonia GenSet Project

Danish State initiative, the EUDP (Energy Technology Development and Demonstration Programme), has announced the ‘NH3 Spark – FutureFlex’ project. It aims to develop a dual-fuel, four-stroke GenSet capable of operating purely on ammonia without the need for a pilot fuel, a first for a commercial, industrial engine.

The project brings together a consortium led by MAN Energy Solutions’ Holeby site along with the Technical University of Denmark (DTU) and Skovgaard Energy, the Danish renewable-energy player. Comprising four phases, the first – ammonia testing on a single-cylinder MAN GenSet – will take place at DTU Construct’s engine laboratory and is scheduled to commence during Q3 2025. This will be followed by full-scale testing under powerplant conditions at Skovgaard Energy’s green-ammonia production facility.

For the purposes of the project, MAN Energy Solutions will take an innovative approach to the dual-fuel concept by developing a small-bore engine where simplicity, price and retrofit suitability are paramount, and which are particularly relevant for the more than 20,000 MAN GenSet engines currently in operation that were designed at the Holeby location. The concept’s suitability for use with other, low-emission fuels will also be evaluated during the project, hence the ‘FutureFlex’ modifier.
