Commodity trader Trafigura is co-sponsoring the development of MAN Energy Solutions ammonia-fuelled engine for maritime vessels
MAN is leading a consortium in Denmark to develop ammonia-fuelled two-stroke engines. The fuel-flexible, two-stroke ammonia engine is expected to be commercially available for large-scale oceangoing ships by 2024, followed by a retrofit package to make existing maritime vessels capable of running on ammonia by 2025.
Ammonia can be stored at the moderately low temperature of -33ºC and supplied at a pressure of 70 bars, and does not have the same storage challenges as LNG or hydrogen. The product is set to be delivered to a shipyard by 2024.
Trafigura executive director and co-head of oil trading, Jose Maria Larocca said “Shipping faces a significant challenge in reducing its emissions, while at the same time the threat of climate change requires urgent action to decarbonise. Developing engines and the supporting infrastructure to provide the industry with the ability to adopt carbon-neutral and carbon-free fuels is key to establishing a greener shipping industry in the near future.”
“By co-sponsoring the MAN Energy Solutions two-stroke ammonia-fuelled engine we are committing ourselves to cross-industry collaboration to bring forward the urgently needed technologies for the maritime energy transition.”
MAN chief executive Uwe Lauber said “The final goal for two-stroke engines is to run them entirely on carbon-neutral and carbon-free fuels and we welcome Trafigura’s support for this key decarbonisation technology. The interest from shipping companies – and indeed from all links in the entire marine supply chain – in new fuel technologies currently has great momentum, however the move to green engines also depends on economic realities. No shipping company can risk having its fleet stranded during this transition, which is why we offer flexible solutions that will allow shipping to adapt to the availability of carbon neutral fuels in the market.”
The company’s senior vice president and head of two-stroke business, Bjarne Foldager, said MAN believes hydrogen-based fuels will ultimately be the shipping fuels of the future.
“To get there, we urgently need a significant IMO-led global carbon levy on marine fuels to encourage and incentivise the use of low and zero-carbon fuels by making these cost neutral compared to the higher emitting fuels we know of today.”
MAN is also partnering with Eastern Pacific Shipping (EPS) and methanol manufacturer OCI to develop methanol and ammonia as marine fuels.
