A fuel cell power generation system includes a fuel cell generating electric power with a fuel, a condenser extracting mixed gas of hydrogen and carbon dioxide contained in water vapor discharged from the fuel cell, a component separator separating the hydrogen and the carbon dioxide from the mixed gas extracted by the condenser, a hydrogen supply path supplying the hydrogen separated by the component separator to the fuel cell, and a carbon dioxide liquefier liquefying the carbon dioxide separated by the component separator.

An autonomous cargo transporting system transports the cargo on a body of water using the natural current of the body of water to deliver cargo to a downstream port. The cargo system is asymmetric since cargo is delivered downstream using the current but the cargo system is disassembled (drastically reducing the weight) for a multimodal return trip back up the body of water.

A method for charging an auxiliary voltage source that provides power for at least one additional component, the additional component being in addition to an electric drive that is powered by a main voltage, is described. The method includes electrically connecting a protection and/or control circuit to the main voltage source via a DC-to-DC converter configured for power supply, and to the auxiliary voltage source via a reverse blocking valve. The method further includes electrically connecting the main voltage source to the auxiliary voltage source via a charging device. The method still further includes charging the auxiliary voltage source via the main voltage source.

A device for producing energy includes an air-towed vessel, and at least one water current turbine linked to the vessel by at least one electric cable. The water current turbine is linked to the vessel by at least one mechanical linking cable to be towed by the vessel. The water current turbine is spaced apart from the vessel, which makes it possible to increase the diameter of the turbine and to reduce the interactions between the turbine and the vessel. Moreover, it is then possible to provide a plurality of water current turbines towed by the same vessel.
