Experts believe equipment of river/sea ships with hydrogen engines is not a distant prospect There are several types of diesel-hydrogen engines for commercial application, between 1,000 kW and 2,800 kW Marine Engineering Bureau is conducting a design study for introduction of new engine concepts into ships of mixed river/sea navigation (primarily RSD59, RST27M and RST27 projects). It is looking into using engines running on alternative fuels ensuring the reduction of GHG emission. First of all, it is about LNG. In 2020, the methanol study began and from 2021, MEB has been provided with the engineering materials on new hydrogen engines of 1,000 – 2,000 kW which is the range of capacity required for the study.
