Recently, the groundbreaking ceremony for the first phase of the hydrogen-based chemical industry chain project at the Longyuan Zhangye Carbon Neutrality Industry Base was held in the Circular Economy Demonstration Park of Zhangye Economic and Technological Development Zone. Hao Xiaodong, the vice mayor of Zhangye, attended and announced the start of the project. The first phase of the hydrogen-based chemical industry chain project at the Longyuan Zhangye Carbon Neutrality Industry Base is planned to require a total investment of 560 million yuan. Gong Yufei, Deputy Secretary of the Party Committee and General Manager of Longyuan Power, said that Zhangye serves as the \"main battlefield\" for Longyuan Power’s development in the new energy sector. In the future, the company will make full use of its strengths in research and innovation, management, and financing to accelerate the progress of existing projects and deepen practical cooperation, with the goal of turning Zhangye into a demonstration area for the low-carbon hydrogen energy industry. Other hydrogen energy projects in Zhangye City include: the Zhangye Jiansheng Clean Energy Hydrogen Production for Protein Synthesis demonstration project, for which the preliminary procedures are currently being carried out. The hydrogen fuel cell production line and 2MW on-site photovoltaic power plant, built in collaboration between Huaneng Corporation and Dongfang Electric, have already commenced construction. The factory for producing hydrogen through electrolysis at a rate of 1,300 standard cubic meters per hour is going through the safety assessment process. Plans are being finalized for a hydrogen energy education center, an innovation research center, and a fuel cell maintenance and testing center. Discussions are underway to determine the construction and operation models for two hydrogen refueling stations. In June 2021, the Zhangye Photovoltaic, Energy Storage, Hydrogen, and Heat Industrialization Demonstration Project of China Energy Engineering Group commenced construction in the Zhangye **-level Economic and Technological Development Zone. The total investment in this project is 4.4 billion yuan. It mainly involves the construction of hydrogen production facilities through water electrolysis and photovoltaic power stations. Integrated fuel, electricity, gas, and hydrogen refueling stations will also be established, and industries related to hydrogen production and utilization will be gradually introduced to create a complete hydrogen production industry chain. The Zhongneng Green Power Zhangye Hydrogen Energy Comprehensive Application Demonstration Project is funded and invested by China Electric Power Engineering Consulting Group, which is part of China Energy Construction Group. The Gezhouba Group Equipment Company of China Energy Construction Group and the Gansu Province Electric Power Design Institute of China Energy Construction Group also participate in the investment and construction of this project. The project is located in the Circular Economy Demonstration Park of the Zhangye Economic and Technological Development Zone in Gansu Province. Construction has already begun on one 1,000 Nm3/h electrolysis water hydrogen production plant, one integrated oil, electricity, and hydrogen fueling station with a hydrogen filling capacity of 500 kg/day, and one 5 MW rooftop photovoltaic power plant. The overall implementation plan for the Huaneng Shandan photovoltaic hydrogen production, energy storage, and integrated application project is as follows: the planned total installed capacity for photovoltaic systems is 200 MW (including 20 MW/40 MWh of energy storage capacity). Build 1 hydrogen production facility by 2023 (with a hydrogen production capacity of 2000 Nm3/h; development will be carried out on a demand-driven basis). Phase 1 (2021–2022) is the first phase of the project, and the construction includes a hydrogen production plant with a capacity of 400 Nm3/h and 1 hydrogen refueling station ； The second phase (2022–2023) is the second-phase project, and the construction activities include the second phase of the hydrogen production facility and 1 hydrogen refueling station. The project supplies high-purity hydrogen to hydrogen fuel cell vehicles in Zhangye City as well as to enterprises in other industries. In addition, in 2020, Huaneng Group’s Gansu branch signed a strategic cooperation agreement with Shandan County in Zhangye City to establish a green circular economy industrial park focused on wind, solar, thermal, hydrogen, and ethanol technologies. Together with the local authorities, they built such an industrial park based on an industrial chain that combines the use of new energy sources for hydrogen production with carbon dioxide utilization for methanol production; as a result, 2.1 million kilowatts of capacity for new energy projects were made available. Building on the existing approved capacity of 660,000 kilowatts, this project will initiate the construction of a 1 million kilowatt coal-fired power plant, as well as other new energy development projects such as a 100,000-ton hydrogen production line in the Hucaotan Circular Industry Zone of Shandan County. The goal is to establish an integrated comprehensive energy base that combines wind, solar, thermal, hydrogen, and ethanol energy sources.
