Environmental Impact Assessment Public Notice for Xinjiang¡äs 60,000-ton Green Hydrogen Project via Water Electrolysis
2025-11-7
On November 4th, the official website of Xinjiang Uygur Autonomous Region Ecological Environment Protection Industry Association released the public notice on the proposed approval of the Environmental Impact Assessment (EIA) for the integrated project of 60,000-ton green hydrogen via water electrolysis and 180,000-ton green melamine high-end chemical new materials by Defengyuan (Hami) Chemical Technology Co., Ltd.
The main projects of this project include: a 60,000-ton/year water electrolysis hydrogen production unit, a 40-ton titanium-based solid alloy hydrogen storage unit, a 340,000-ton synthetic ammonia unit, a 900,000-ton/year urea unit, two sets of 90,000-ton/year melamine units, and two sets of 400,000-ton/year new-type compound fertilizer units. Public works include heating, water supply, drainage and power supply and distribution projects. Storage and transportation projects include liquid ammonia spherical tanks, product warehouses and other raw material and auxiliary material storage warehouses. Auxiliary projects include circulating water stations, substations, comprehensive office buildings, etc. Environmental protection projects include waste gas treatment facilities, wastewater treatment facilities, solid waste temporary storage facilities, noise control measures, environmental risk prevention and control facilities, etc.
The maximum hydrogen production capacity is 126,000 Nm³/h, with an annual hydrogen output of 60,000 tons and a by-product oxygen output of 480,000 tons. The project has 8 water electrolysis workshops equipped with 128 electrolyzers (including 2 standby ones). Each single electrolyzer has a hydrogen production capacity of 1,000 Nm³/h and a hydrogen production pressure of 1.5 MPa (hydrogen at the purification outlet). Each electrolysis workshop is equipped with 16 electrolyzers, 4 sets of gas-liquid separation systems, 2 sets of hydrogen purification systems and 2 sets of oxygen purification systems. Every 4 electrolyzers share 1 set of gas-liquid separation system, and each 2 sets of gas-liquid separation systems are matched with 1 set of hydrogen purification and oxygen purification facilities. Supporting water and alkali injection facilities will be constructed.
