Abstract

When a sailing ship which has large rigid wing sails such as the Wind Challenger Sail runs in a sufficiently windy sea, the thrust by sails is utilized to not only drive the ship at the proper speed but also to rotate an underwater turbine at significant speed and torque. The turbine generates electricity which is used for the electrolysis of water to generate hydrogen. The hydrogen is stored using toluene in the form of methylcyclohexane (MCH), which is in liquid form under normal temperature and pressure. MCH is stored in the ship's tank as hydrogen fuel. In the case of weak winds when the sails cannot generate sufficient thrust, using the hydrogen generated by the dehydrogenation device, the fuel cell works and supplies electricity to the electric motor propeller for the ship's propulsion. Thus, the ship can run at a constant speed regardless of wind speed and direction.
