Recently, the EPC project for a demonstration project related to green electricity and green hydrogen developed by Yangtze Power, a project undertaken jointly by Tunnel Co., Shanghai Energy Construction, and Yangtze Survey, Planning, Design and Research Co., Ltd. (Yangtze Institute), entered the preliminary preparation stage ahead of its commencement. This project is a hydrogen production via water electrolysis and hydrogen refueling demonstration project initiated by China’s Yangtze Power Group in the Three Gorges area. It is also the first of its kind in China for inland hydrogen fuel cell-powered ships as well as integrated hydrogen production and refueling stations, with some of its key technologies reaching world-leading levels. The project has a hydrogen production capacity of 200 standard cubic meters per hour, and a hydrogen refueling capacity of 500 kilograms per day; it can provide hydrogen refueling services for inland hydrogen fuel cell-powered ships as well as tourist buses in the Three Gorges Dam area. Tunnel Co., Shanghai Nengjian, will work closely with Yangtze River Research Institute to be responsible for the construction of various supporting facilities, including a hydrogen production system with a capacity of 500 kilograms per day, 1 marine hydrogen refueling system, 1 vehicle hydrogen refueling system, electrical control systems, as well as water supply and drainage systems. Tunnel Co., Ltd. and Shanghai Energy Construction will provide an integrated solution for manufacturing, storage, and refueling for this project. It is reported that, drawing on over 10 years of technical expertise and project experience, the Shanghai Energy Construction project team of Tunnel Co., Ltd. took full account of the project’s safety, feasibility, and advancement. They installed electrolyzer units capable of producing hydrogen at a rate of 200 standard cubic meters per hour, as well as multi-level hydrogen storage systems and refueling systems for vehicles and ships. This approach creates an integrated model for hydrogen production, storage, and refueling, thereby reducing hydrogen refueling times and enhancing the efficiency and safety reliability of hydrogen stations. Furthermore, in terms of hydrogen storage, the company classifies hydrogen tanks into three levels, allowing for refueling at various levels to meet the hydrogen fuel requirements of different vehicle models.
From project design and construction to subsequent operation and management, this project will make full use of digital technologies to create a management platform that covers the entire lifecycle of hydrogen refueling stations. Based on BIM applications, it will achieve comprehensive utilization of digital twin technology through the deep integration of various functional aspects such as design during the construction phase, construction activities, procurement, as well as safety and emergency management during the operation phase. The project will also employ an intelligent hydrogen energy management system, which uses a distributed architecture to organize system control and data in layers, thereby enabling the monitoring and management of multiple hydrogen production units as well as various energy supply sources. At the same time, the project adopts advanced electrolytic water hydrogen production technology, resulting in hydrogen with a purity of up to 99.999%. The hydrogen production process generates almost no carbon emissions and causes no pollution, offering significant environmental benefits. Unlike traditional ground-based vehicle refueling, the vertical height difference between the top surface of the Yangjiawan Wharf, where this project is located, and the lowest navigable water level is approximately 11 meters; moreover, the ship remains in a state of constant movement due to the effects of water currents during refueling. Faced with the two major technical challenges of refueling at large vertical height differences and dynamic refueling, the project team conducted specialized research on factors affecting hydrogen refueling speed at such heights as well as the design of mechanical arms for marine hydrogen refueling hoses. This research provided technical support for the project and also served as a model for similar projects in the future. Focusing on the technical challenges, breakthrough technologies, and demonstration aspects involved, the project team will initiate research initiatives related to the development and study of experimental platforms for proton exchange membrane electrolysis for hydrogen production using both imported and domestic technologies, the design and implementation of integrated hydrogen production and refueling stations at ports, as well as the research and application of ship-to-shore refueling technologies, thereby providing innovative ideas for the hydrogen industry. It is reported that the construction of this project is expected to be completed in the first half of next year. It will not only provide technical support for the pilot implementation of the \"Hydrogenized Yangtze River\" initiative but also further promote the green transformation of the industrial sector in the Wuling area of Yichang.
