MAN Energy Solutions has announced plans to bring a methanol-fuelled variant of its high-speed 175D engine to market by 2026. The launch of the dual-fuel engine, the 175DF-M, will also include the introduction of a retrofit solution for existing 175D engines.

The 175DF-M will be optimised for diesel-mechanical and diesel-electric propulsion to achieve the largest methanol share and best efficiency for various applications and load profiles. In fact, the engine has already been awarded the ‘fuel ready’ certificate by DNV, guaranteeing the introduction of this dual-fuel methanol technology.

Florian Keiler, Head of High Speed, MAN Energy Solutions, said: “The MAN 175D has proven to be very competitive in terms of sustainability and efficiency with the lowest fuel consumption, lowest lube-oil consumption and longest overhaul times in its class, minimising its environmental footprint. In terms of future fuels, the next logical step, apart from being able to run on 100% bio-fuels, is to ensure methanol combustion.”
