Recently, the EPC general contracting project of Jiuquan Long term Wind solar Hydrogen Storage Integration Demonstration Project has officially opened for public bidding, marking another heavyweight move in the integrated layout of Gansu Jiuquan's new energy industry. The total investment of this project is about 5.207 billion yuan, relying on local high-quality wind and solar resources, to create a fully integrated demonstration project of "wind and solar power station development+hydrogen production+hydrogen storage+hydrogen power generation", which will further improve the regional green hydrogen industry system and assist in the consumption of new energy and the construction of new power systems.

It is understood that this project has been approved for construction by the Development and Reform Bureau of Jinta County, Jiuquan City with document number [2026] 05. The project owner and tenderer are Jiuquan Hydrogen Storage Era New Energy Technology Co., Ltd. The project construction funds are self raised by the enterprise and bank loans, with a contribution ratio of 100%. Currently, the bidding construction conditions are fully met. This bidding is not divided into sections, and the overall implementation adopts the EPC turnkey general contracting mode, with a planned construction period of 24 months. The project is located in Jinta County, Jiuquan City, Gansu Province, and is divided into two major construction areas: the new energy field area and the hydrogen production station. Among them, the new energy field is located east of the Beihewan Circular Economy Industrial Park in Dazhuangzi Town, Jinta County. The wind farm covers an area of about 109.19km ², and the photovoltaic field covers an area of about 4.06km ²; The hydrogen production station is located in the core industrial area of Beihewan Circular Economy Industrial Park, with a land area of approximately 324.64 acres. The location is advantageous and the industrial supporting foundation is solid. The total investment of the project is clearly divided, with an investment of approximately 2.705 billion yuan in the integrated wind solar energy storage sector and approximately 2.502 billion yuan in the hydrogen production plant and station sector. The two major sectors work together to build a closed-loop industrial chain for green electricity hydrogen production and hydrogen storage power generation.

As an integrated new energy demonstration project, this project covers a wide range of construction content and has a complete technical system. The core is divided into three major sections: new energy power, hydrogen production and compression storage, and hydrogen gas turbine power generation. The entire process adopts mature and advanced technology routes to achieve 100% green hydrogen preparation and application. In the new energy and power sector, the project will build 300MW wind power, 300.5483MWp photovoltaic, 180MW/360MWh grid type electrochemical energy storage, and supporting boosting, transmission, and on-site supporting projects. The wind power project is equipped with 48 6.25MW wind turbines and a supporting 62.6km collection line, with an annual grid connected electricity capacity of 791.214 million kWh; The photovoltaic project adopts high-efficiency N-type monocrystalline silicon double-sided double glass modules, matched with string inverters and fixed brackets, with an annual power generation of 492.297 million kWh; The energy storage system adopts 314Ah lithium iron phosphate batteries, configured according to a 30%, 2-hour standard, and evenly distributed in two newly built 110kV booster stations.

At the same time, the project will build two 110kV booster stations and 33.7km transmission lines, with complete supporting facilities such as site roads, fire protection, water conservation, environmental protection, etc., to ensure stable output and transmission of new energy electricity. In the hydrogen production, compression, and storage sectors, the total planned hydrogen production scale of the project is 5 × 10 ⁴ Nm ³/h. Three new hydrogen production plants will be built, equipped with 38 high and low pressure adaptive alkaline electrolysis cells, combined with gas-liquid separation and hydrogen purification devices, which can produce high-quality green hydrogen with a purity of not less than 99.999%. The total annual production of hydrogen will reach 20137 tons. The hydrogen storage process is equipped with 24 large 2000m ³ hydrogen storage spherical tanks, with a total hydrogen storage capacity of 576000 Nm ³. It is constructed according to Class III pressure vessel standards and has excellent safety performance. Simultaneously configure multiple screw and reciprocating hydrogen compressors to meet the pressure level requirements for hydrogen storage and transmission, and build a new 110kV main pressure reduction station and a complete set of public engineering facilities to provide guarantees for the stable operation of the hydrogen production and storage system.

In the hydrogen gas turbine power generation sector, the project will build six 30.5MW pure hydrogen gas turbine power generation units with a total installed capacity of 183MW. The pure hydrogen direct combustion simple cycle power generation technology will be adopted, and the system's simple cycle efficiency will reach 39%. Six sets of high-efficiency SCR denitrification devices will be constructed to achieve a denitrification efficiency of ≥ 95% and strictly control pollutant emissions. The annual average power generation of the project is 244.5891 million kWh, with a daily peak shaving of 4.1 hours. It can effectively undertake the functions of grid peak shaving and flexible power supply support, solve the problems of fluctuation and intermittency in new energy generation, and achieve efficient recycling of green hydrogen energy storage and hydrogen energy generation. This bidding is a full process EPC turnkey general contracting, covering all work throughout the project lifecycle, including survey and design, equipment and material procurement, civil engineering installation, commissioning and trial operation, procedure handling, special acceptance, quality assurance services, etc.

Specifically, it involves the handling of project compliance documents, land leasing assistance, equipment supervision and transportation, engineering construction, environmental protection and water conservation special construction, grid connection testing and acceptance, file transfer, 2-year defect liability period warranty services, and other comprehensive work. All supporting costs are included in the bidding quotation to ensure that the project meets the standards and is effective immediately upon landing and production. At the same time, it is explicitly stated that the winning bidder shall independently handle the site selection, procedures, and construction coordination of temporary facilities, and allocate dedicated personnel to liaise with government departments at all levels to ensure the orderly progress of construction. The project specifies strict construction quality standards, requiring all engineering construction to comply with current national, industry, and local regulations, strictly meet special requirements such as hydrogen production, hydrogen storage, hazardous chemical safety, explosion prevention and fire protection, special equipment operation and maintenance, and grid connection. The project needs to achieve a 100% pass rate for sub projects and sub projects, as well as a 100% pass rate for the first acceptance of unit projects, to eliminate quality hazards, ensure excellent design and construction quality, fully meet completion performance assessment indicators, and standardize and complete engineering archives.Editor/Xuning
