甘肃酒泉长时风光氢储一体化示范项目启动EPC招标Gansu Jiuquan Long-Duration Wind and Solar Hydrogen Storage Integrated Demonstration Project Launches EPC Tender

Recently, the public tender for the EPC general contracting project of the Jiayuguan Changshi Wind-Solar Hydrogen Storage Integrated Demonstration Project was officially launched, marking another significant move in the integrated layout of the renewable energy industry in Jiuquan, Gansu. The total investment of the project is approximately 5.207 billion yuan. Relying on the local high-quality wind and solar resources, it aims to build an integrated demonstration project covering the full chain of 'wind-solar power station development, hydrogen production, hydrogen storage, and hydrogen power generation,' which will further improve the regional green hydrogen industry system and support the consumption of renewable energy as well as the construction of a new type of power system.

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 is Jiuquan Hydrogen Storage Era New Energy Technology Co., Ltd. The construction funds are entirely provided by the enterprise through self-financing and bank loans, with a 100% contribution ratio. The project currently fully meets the conditions for tendering and construction. This tender is not divided into sections and will be implemented under an overall EPC turnkey contracting model, with a planned construction period of 24 months. The project is located in Jinta County, Jiuquan City, Gansu Province, and is generally divided into two major construction areas: the renewable energy site and the hydrogen production station.

From the perspective of spatial layout, the renewable energy park is located east of the Beihewan Circular Economy Industrial Park in Dazhuangzi Town, Jinta County. The wind farm covers an area of approximately 109.19 square kilometers, and the photovoltaic park covers an area of about 4.06 square kilometers. The hydrogen production station is located on the core industrial site of Beihewan Circular Economy Industrial Park, with a land area of about 324.64 mu. The total project investment is clearly divided, with the integrated wind, solar, and storage sector investment at approximately 2.705 billion yuan, and the hydrogen production and station sector investment at approximately 2.502 billion yuan. The two major sectors collaborate and interact to form a closed-loop industrial chain of green power hydrogen production and hydrogen storage power generation.

In the renewable energy power sector, the project will construct 300 MW of wind power, 300.5483 MWp of photovoltaic, 180 MW/360 MWh network-type electrochemical energy storage, as well as supporting booster, transmission, and field auxiliary facilities. The wind power project will be equipped with 48 units of 6.25 MW wind turbines, along with the construction of 62.6 km of collection lines, with an annual grid-connected electricity output of up to 7,912.14 million kWh. The photovoltaic project will use high-efficiency N-type monocrystalline silicon bifacial double-glass modules, paired with string inverters and fixed mounts, with an annual power generation of 4,922.97 million kWh. The energy storage system will use 314 Ah lithium iron phosphate batteries, configured to 30% for 2 hours, evenly distributed across two newly constructed 110 kV booster stations, and a new 33.7 km transmission line will also be built.

In the hydrogen production, compression, and storage sector, the project plans a total hydrogen production capacity of 50,000 Nm³/h, with the construction of 3 new hydrogen plants equipped with 38 high- and low-pressure adaptable alkaline electrolyzers, along with gas-liquid separation and hydrogen purification units. This setup can produce high-quality green hydrogen with a purity of no less than 99.999%, with an annual hydrogen output of 20,137 tons. The hydrogen storage phase includes 24 large hydrogen storage spheres of 2,000 m³ each, with a total storage capacity of 576,000 Nm³, built according to three types of pressure vessel standards, ensuring excellent safety performance, and equipped with multiple screw and reciprocating hydrogen compressors to meet pressure level requirements.

In the hydrogen gas turbine power generation sector, the project involves the construction of six new 30.5MW pure hydrogen gas turbine power generation units, with a total installed capacity of 183MW. It adopts pure hydrogen direct combustion simple cycle power generation technology, with a system simple cycle efficiency of 39%, and is equipped with six sets of high-efficiency SCR denitrification devices, with a denitrification efficiency of ≥95%. The project’s average annual power generation is 2,445.891 million kWh, with an average daily peak regulation of 4.1 hours, effectively undertaking grid peak regulation and flexible power supply support, addressing the volatility and intermittency problems of renewable energy generation.

This tender is for a full-process EPC turnkey contract, covering all work throughout the project lifecycle, including survey and design, equipment and material procurement, civil construction and installation, commissioning and trial operation, procedure handling, special inspections, and warranty services, with all associated costs included in the bid price. The project specifies stringent construction quality standards, requiring a 100% pass rate for sub-items and sub-projects, and a 100% first-pass qualification rate for individual units, to eliminate quality risks and ensure full compliance with completion performance evaluation indicators.
