MAN Engines first dual fuel hydrogen engines in work boat

Availability, driving comfort and operational safety are thus always guaranteed at the high level that a traditional diesel engine is known for.

MAN Engines put its first two dual fuel hydrogen-powered engines for workboats into serial operation.

These comprise two twelve-cylinder diesel engines of type MAN D2862 LE448, each with an output of 749 kW (1019 hp) at 2100 rpm. The engines are IMO Tier III-certified and equipped with a Selective Catalytic Reduction exhaust gas after-treatment system. Both V12 engines have been prepared for dual fuel operation by MAN Engines, and supplemented with a hydrogen injection system by development partner CMB.TECH. The low-emission engine is used on the world’s first hydrogen-powered crew transfer vessel (CTV), the “Hydrocat 48” from Windcat Workboats.

A proven V12 marine engine is thus used in which hydrogen is introduced into the charge air via an adapter and is added to the combustion cycle. The combustion process is thereby started according to the diesel principle, which requires the injection of approx. 5% of diesel fuel. The diesel fuel common rail injection parameters have been optimised here for dual fuel operation.

A further advantage of using the conventional and sophisticated diesel engine is the accustomed easy handling when it comes to maintenance and service. Moreover, for instance, pure diesel operation can continue without interruption if the hydrogen supply is exhausted.

MAN Engines offers its customers and partners solutions like the “MAN Smart HYBRID Experience” hybrid system or engines for gas/electric drives to contribute to CO2 reduction and sustainable shipping. Now that the MAN D2862 LE448 dual-fuel engines for workboats are ready for series production, a further milestone has been reached to that effect.

Werner Kübler, Head of Development at MAN Engines, said, “We were also able to achieve the best consumption values in dual fuel operation, and ensure the same operating behaviour as displayed by diesel operation at full load. At the same time, we also reduce CO2 tailpipe emissions through the use of hydrogen by an average of approx. 50%, and even up to 80% as a peak value.”

Willem van der Wel, Managing Director of Windcat Workboats, said, “By starting with dual fuel combustion engines, we can make hydrogen technology operational in the industry and kick-start further development of the technology, regulation, supply chain, etc.”
