The Jilin Daan wind-solar hydrogen-to-ammonia integration project is designed based on a full industrial chain concept of “green hydrogen consuming green electricity, green ammonia consuming green hydrogen, and integrated source-grid-load-storage coordination.” After commissioning, the project is expected to produce 32,000 tons of green hydrogen and 180,000 tons of green ammonia annually, reducing carbon emissions by approximately 650,000 tons per year and saving 230,000 tons of standard coal. The project adopts the CEEG ZHSSFT-12500/10 oil-immersed transformer, which features high overload capability, long service life, high reliability, and strong operational safety, ensuring stable performance for large-scale integrated energy systems.
The Korla New Energy Hydrogen Production Project in Xinjiang is the first off-grid photovoltaic green hydrogen integrated application project in the region. As the first “New Energy + Hydrogen Energy” source-grid-load-storage-hydrogen integrated project in Bazhou, it consists of three main sections: photovoltaic power generation, hydrogen production and refueling station, and hydrogen energy application. To ensure the high-quality commissioning of the project, CEEG developed and manufactured the ZSCB-3920/6.3 dry-type rectifier transformer. The product features low partial discharge, strong harmonic resistance, high overload capacity, and high efficiency, ensuring reliable operation under complex power conversion conditions.
The Narisu Project is the first batch of wind-solar-hydrogen integration demonstration projects in Inner Mongolia Autonomous Region, and it is also the first and largest ten-thousand-ton-scale new energy hydrogen production project in Ordos, Inner Mongolia, and even in China and globally. The project is jointly developed by China Three Gorges New Energy (Group) Co., Ltd. and Man Shi Investment Group Co., Ltd. The project utilizes a reclaimed mining area for the construction of a photovoltaic power station, with an average annual power generation of approximately 740 million kWh. Of this, 20% is directly supplied to the local grid, while the remaining 80% is used for green hydrogen production. The project adopts CEEG’s independently developed, designed, and manufactured ZHSS-12000/35 24-pulse IGBT hydrogen rectifier transformer, ensuring high-efficiency, stable, and reliable power conversion for large-scale hydrogen production applications.
The Canada single-unit 1000 m³ hydrogen production project adopts the CEEG ZHSZCB-5800/35kV hydrogen production dry-type rectifier transformer. CEEG dry-type rectifier transformers utilize a new insulation structure and advanced manufacturing processes, significantly improving short-circuit withstand capability and electrical strength, ensuring excellent performance and high reliability. During the design stage, full consideration is given to the impact of harmonics generated by rectifier components on transformer windings and core. Sufficient design margin allows the windings and core to withstand additional temperature rise caused by harmonics while maintaining low noise levels and ensuring extended service life. In addition, the system simplifies the grid configuration and can be integrated directly with rectifiers and other electrical equipment. It does not require a separate distribution room, thereby reducing initial investment costs.
