Hydrogen motor for water craft

A method of propelling a watercraft using hydrogen, comprising the steps of:

• providing a combustion chamber defining an upper portion and a lower portion;
• allowing water to flow from an exterior of the watercraft into the lower portion of the combustion chamber through a first check valve;
• introducing a mixture of hydrogen and oxygen into the upper portion of the combustion chamber;
• igniting the mixture of hydrogen and oxygen in the upper portion of the combustion chamber such that expanding gases force the water in the lower portion of the combustion chamber into an accumulator system through a second check valve;
• and
• arranging a propulsion control valve to allow water stored by the accumulator system to flow to the exterior of the watercraft.

A system for propelling a watercraft using hydrogen, comprising:

• a combustion chamber defining an upper portion and a lower portion;
• an accumulator system for storing pressurized fluid;
• a first check valve arranged to allow water to flow from the exterior of the watercraft into the lower portion of the combustion chamber;
• a second check valve arranged to allow water to flow from the lower portion of the combustion chamber to the accumulator system;
• a nozzle;
• a propulsion control valve arranged to control the flow of water from the accumulator system to the exterior of the watercraft through the nozzle;
• a hydrogen source for introducing hydrogen into the upper portion of the combustion chamber;
• an oxygen source for introducing oxygen into the upper portion of the combustion chamber;
• a water source for introducing water into the upper portion of the combustion chamber;
• an ignition system for igniting a mixture of hydrogen and oxygen in the combustion chamber to create expanding gases that force the water in the lower portion of the combustion chamber into the accumulator system through the second check valve;
• an ignition control system for controlling the hydrogen source, the oxygen source, the water source, and the ignition system according to an ignition cycle;
• and
• a propulsion control system for operating the propulsion control valve to allow water in the accumulator system to flow to the exterior of the watercraft at a desired flow rate.
