We are designing a hydrogen internal combustion spark ignition engine for use on a large cargo ship.
International Maritime Organisation (IMO) and the International Transport Forum (ITF) reports indicate that 2.6% of total green house gas (GHG) emissions are from shipping.
GHG enissions are expected to triple by 2050 and the IMO targets net-zero emissions by 2050 in the GHG Strategy (2023)
while container ships release an annual average of 140 million metric tons of carbon dioxide, bulk carriers contribute a total of 440 million metric tons of carbon dioxide emissions each year.
Large cargo ships are powered by Compression-Ignited two-stroke Internal Combustion Engines.
Hydrogen has a stochiometric air to fuel ratio from 34:1 all the way up to 180:1 by mass compared to that of petrol (14.7:1) and of Diesel(18:1).
It is possible to modify already existing engines to run on Hydrogen fuel. (National Research Council of Canada)
An air-cooled single piston diesel engine operated optimally with minimal changes to the piston shape and compression ratio of the combustion chamber.
Our aim is to modify already existing cargo ship engines to run on hydrogen fuel while still maintaining all other components surrounding the engine hence making it more feasible to convert current cargo ships to running hydrogen engines.
Tanks for Hydrogen storage will be placed above ontop of the ship above the rudder.
Oxygen can be stored and used for emergency cases on the ships or otherwise released into the air.
The solar kit and wind proppellers will be raised above the bridge will be placed at the accomodation area.
The engine will be fitted under the hull.
We intend on designing an inlet near the propeller where saltwater can be pumped, processed and can run thorugh the electrolyzer.
