MAN’s marine dual fuel H2 engine
Runs on diesel and hydrogen
MAN’s dual fuel H2 engine for commercial vessels can run on a combination of two fuels: diesel oil and hydrogen. It is just as powerful and reliable as a conventional diesel engine but releases significantly less CO2 into the atmosphere. In addition, it can immediately switch to full-diesel mode if there’s some kind of issue with the hydrogen. In other words, you are assured of uninterrupted operation, with the well-known robustness and fuel efficiency of a MAN ship’s engine. Moreover, you are always compliant with IMO Tier III emission standards, regardless of which mode the engine is set to: diesel or dual fuel.
Lower emission
And maximum reliability
Diesel mode
Dual fuel mode
Depending on the engine load, you generally only have to combust a small quantity of diesel oil after going to dual fuel mode. This leads to a considerable reduction in CO2 emissions. For example, in the case of a wind farm support vessel with a daily load, this effectively cuts the vessel’s CO2 emissions in half. Moreover, dual fuel mode also reduces the release of particulates and nitrogen oxides (NOx).
Dual fuel engine with monitoring and venting system
Any component of the dual fuel engine that carries or contains hydrogen is double-walled, and the engine’s hydrogen monitoring system immediately flags possible leaks. At that point, the engine’s venting system safely sequesters any hydrogen that may have leaked and stops the supply of hydrogen to the engine. The engine automatically switches to full-diesel mode and continues to supply power without interruption.
The same capacity, but with lower emissions
As flexible as always
With the MAN dual fuel engine, you can use hydrogen as a fuel and reduce your emissions – while retaining maximum flexibility and keeping the same capacity at your disposal.
Exhaust after-treatment in diesel mode
The effective after-treatment of exhaust gases by MAN’s SCR system ensures that less nitrogen oxides (NOx) are released into the atmosphere.
Substiantially lower carbon emissions in dual fuel mode

Depending on the engine’s operating point, you generally only have to combust a small quantity of diesel oil after going to dual fuel mode. This leads to a considerable reduction in CO2 emissions.
Compliance with IMO Tier III emission standards

Regardless of which mode the engine is in – full-diesel or dual fuel – you are always compliant with IMO Tier III emission standards.
