NSTsolar assists the country’s first 10,000-ton Narisong hydrogen production step-down station

At 14:38 on December 29, 2023, the Narisong hydrogen production step-down station successfully delivered power at one time. At 18:00 on December 29, 2023, the Narisong photovoltaic boost station successfully delivered power at one time. This marks that The country's first 10,000-ton new energy hydrogen production project, the Narisong photovoltaic hydrogen production industry demonstration project in Jungar Banner, Ordos City, Inner Mongolia, was successfully connected to the grid. This project uses the ZHSS-12000/35 24-pulse IGBT hydrogen production rectifier transformer independently developed, designed, and manufactured by NSTsolar. The Narisong project is the first batch of integrated wind and solar hydrogen production demonstration projects in the Inner Mongolia Autonomous Region. It is the first largest 10,000-ton new energy hydrogen production project in the Ordos, Inner Mongolia Autonomous Region, the country, and even the world. It is funded by China Three Gorges New Energy (Group) Co., Ltd. The company is building a joint venture with Manshi Investment Group Co., Ltd. The project uses coal mining backfill areas to build photovoltaic power stations. The average annual power generation is about 740 million kilowatt hours, of which 20% will be directly transmitted to the local power grid and the remaining 80% will be used for green hydrogen production. The project installs 15 sets of 1,000 standard cubic meters/hour alkaline electrolytic hydrogen production equipment, with an annual output of about 10,000 tons of hydrogen and about 80,000 tons of oxygen. To ensure the security of the power grid, the project uses 10,000-ampere IGBT power supplies (insulated gate bipolar transistors) for the first time to replace traditional thyristors. This is the first large-scale use in the global green electricity hydrogen production industry. It can improve the comprehensive conversion efficiency of the hydrogen production system and play a leading role in the technological development of domestic hydrogen production power sources.
