Caterpillar Marine reports that it has made significant advances in the development of its methanol dual-fuel Cat 3500E marine engines. Under a memorandum of understanding (MOU) with Damen Shipyards, it will deploy the first set of field demonstrator 3500E marine engines in 2026.
The Cat 3500E marine engines will use innovative dual-fuel technology based on proven diesel fuel systems that will supports vessels’ low-pressure – below 10 bar – fuel systems.
The methanol dual-fuel Cat 3500E engine targets the same performance and durability as the current 3500E diesel engine while meeting emission standards and delivering 100% power.
The methanol dual-fuel 3516E engine development takes a holistic approach, targeting the highest methanol substitution while meeting regulated emissions. Non-regulated emissions, such as formaldehyde, are part of the focus, and the IMO III solution will abate regulated and non-regulated emissions, targeting the same aftertreatment space.
