en.Wedoany.com Reported - Recently, China's first 5MW off-grid solar hydrogen production project with fully independent intellectual property rights was officially put into operation in Ordos City, Inner Mongolia, marking the transition of intrinsically storage-free off-grid hydrogen production technology from laboratory validation to engineering implementation.

This project is a key component of the Shenneng Otog Banner 505MW Wind-Solar Hydrogen Production and Green Ammonia Synthesis Project. After full-process commissioning, the project successfully produced its first cubic meter of green hydrogen, capable of generating approximately 6,000 cubic meters of high-purity hydrogen daily. The system directly supplies direct current (DC) power through a 5MW photovoltaic array, operating entirely independently of the main power grid, and precisely matches hydrogen production load demands via flexible intelligent control processes. Without the need for large-scale energy storage, the system achieves stable operation. Compared to traditional off-grid solutions, this model simplifies system architecture, reduces construction costs, and eliminates reliance on the public grid, ensuring the cleanliness and supply autonomy of the entire electrolytic hydrogen production process from the source.

The technology was initially researched by Tsinghua University with support from the National Natural Science Foundation of China. It was further incubated as a national key project on platforms such as the "Sichuan Energy Internet Research Institute, Tsinghua University" and the "State Key Laboratory of New Power System Operation and Control, Tsinghua University," and ultimately underwent megawatt-level engineering validation in the Shenneng Otog Banner 505MW Wind-Solar Hydrogen Production and Green Ammonia Synthesis Project.

As one of the first batch of national hydrogen energy pilot projects in the energy sector, the Shenneng Otog Banner Wind-Solar Hydrogen Production and Green Ammonia Synthesis Project will continue long-term operational validation and system optimization, providing data support and engineering references for industry standard development, project promotion, and the large-scale development of the green hydrogen industry.
