Hybrid drive for ships / boats

Abstract

I hereby apply for protection of the concept of producing green hydrogen from water and wastewater on ships using the “cost-effective hydrogen production plant” in order to operate hydrogen Wankel engines directly as a drive, or to generate electrical energy with hydrogen Wankel engine generators, store it in batteries and lifting power plants and use electric motors or hydrogen Wankel engines as a drive.

Description

[0001] Batteries can also be charged on cargo ships and other vessels using PV and / or wind energy, or the energy can be stored in a lifting power plant with weights and a DC electric motor / generator. Hydrogen Wankel engine generators can also be used for this purpose.

[0002] The hydrogen for the hydrogen Wankel engine generator can be produced from river water, sea water or waste water using the “Cost-effective hydrogen production plant” already protected under DPMA No. 20 2021 002 421.2.

[0003] The “magnesium hydrogen paste” patented by the Fraunhofer Institute can produce hydrogen by adding water.

[0004] In addition, excess energy from PV and / or wind turbines can be stored in a lifting power station with weights (cast iron, concrete, water, etc.), thus ensuring, for example, a permanent DC power supply to the electrolysis plant. For this purpose, the "lifting device for weights," already protected under DPMA No. 20 2021 001 950.2, is used.

[0005] On the left side of the lifting bar there is a clutch with brake (mechanical or electric), then a harmonic drive gearbox or similar with a ratio of approx. 1 / 10000, then a DC or AC electric motor (approx. 15KW or similar) for faster lifting of the weights.

[0006] On the right side of the lifting device, there is a clutch with a brake (mechanical or electric) on the lifting rod, followed by a harmonic drive gearbox or similar with a ratio of approximately 1 / 100,000, followed by a DC electric motor / generator (approx. 15 kW or similar) also for lifting the weights or for generating energy.

[0007] The ship can be powered by electric motors or directly by hydrogen Wankel engines.
