Recently, the main structure of the water electrolytic hydrogen production unit of the 600,000-kilowatt off-grid renewable energy hydrogen production Phase I project in the Pingluo Coal Mining Subsidence Area of China Coal successfully topped out, marking the transition of the 'green electricity—green hydrogen—green chemical' carbon reduction pathway from planning to implementation.

This project is Shanxi Province's first large-scale renewable energy off-grid hydrogen production demonstration project coupled with coal chemical industry. The water electrolytic hydrogen production unit that has now topped out is the core unit of the green hydrogen-chemical coupling section, constructed by Sinochem Second Construction Group. Its construction progress directly affects whether the subsequent hydrogen production system can enter installation and commissioning on schedule.

In terms of construction difficulty, the unit has a complex structure, with some formwork parts exceeding 8 meters in height and gable wall erection reaching 15.8 meters, making it a relatively high-risk component project. This places high demands on the design, installation, and monitoring of the formwork support system.

During construction, the project team strictly implemented a specialized construction plan based on expert review, clarified safety technical handovers, reinforced job responsibilities, increased the frequency of on-site inspections, and strictly controlled key procedures such as scaffold erection, fastener tightening, and concrete pouring, ensuring safety management was applied at every step.

To address construction challenges such as high loads, strong wind disturbances, and structural vibrations, the project team conducted early assessments and implemented precise measures, while simultaneously carrying out dynamic monitoring of the scaffolding and formwork support systems. Any identified hazards were immediately investigated and rectified, ensuring that high-standard construction laid a solid foundation for the precise installation of subsequent equipment and system commissioning.

Relying on the land resources in the coal mining subsidence area and wind-solar resources, the project produces green hydrogen in an off-grid manner and integrates it with coal chemical production, exploring a low-carbon transition path for coal enterprises. The combined use of subsidence land and wind-solar resources allows the electricity used in the hydrogen production process and the hydrogen demand in the chemical process to be connected within the same area.

After the main body of the water electrolysis hydrogen production unit is capped, the project will enter the equipment installation and system commissioning stage. Subsequent construction will take the capping of the unit as a new starting point, promoting technical integration of green power-based hydrogen production with coal chemical production, and accumulating engineering experience to explore carbon reduction pathways in similar resource-based regions.
