Patent granted for direct-current coupling hydrogen production system
A recently granted patent (Publication Number: US12003109B2) discloses a direct-current coupling hydrogen production system that includes an electricity generation system and multiple hydrogen production electrolyzer systems. The system is designed to efficiently produce hydrogen by controlling the supply of electrical energy to the electrolyzer systems. The electricity generation system comprises a controller, renewable energy systems, conversion systems, and a power switching unit. The controller acquires maximum power point tracking (MPPT) values from the conversion systems to determine which hydrogen production electrolyzer system should be operated based on these values and the system's minimum startup electrical parameter. This ensures that each electrolyzer system receives sufficient electrical energy for independent operation.
Furthermore, the patent details different configurations of the system based on the placement of the conversion systems within the electricity generation system. It also includes provisions for hydrogen storage tanks to store the produced hydrogen and outlines the use of metal or non-metallic pipelines for gas transportation. The system's power switching unit consists of bus switch modules and electrolyzer input switch modules to facilitate the distribution of electrical energy to the hydrogen production electrolyzer systems. The patent also covers methods for controlling the system, emphasizing the independent operation of each electrolyzer system based on the number of systems in operation. Overall, the patent presents a comprehensive and innovative approach to hydrogen production through direct-current coupling, highlighting the system's efficiency and flexibility in operation.
