Core Viewpoint - The collaboration between China National Petroleum Corporation (CNPC) and Changqing Oilfield has led to the development of China's first 100 kW oil and gas associated wastewater electrolysis hydrogen production system, which has achieved stable operation in the Sulige gas field [1] Group 1: Technology and Innovation - The system features a unique dual-structure electrolyzer design that operates under both atmospheric and pressurized conditions, allowing for direct treatment of high-concentration wastewater while simultaneously degrading pollutants and producing hydrogen [1] - The pressurized electrolyzer processes purified brine for large-scale, high-purity hydrogen production, overcoming technical challenges related to material deactivation in high-salinity and high-pollution environments [1] Group 2: Operational Performance - During the demonstration period, the system processed a total of 24 tons of wastewater, including fracturing flowback and produced water, achieving a maximum hydrogen production rate of 40 standard cubic meters per hour with a hydrogen purity of 99.99% [1] - The chemical oxygen demand (COD) removal rate from the wastewater reached 99%, indicating effective pollution treatment [1] Group 3: Economic Impact - The system's levelized cost of hydrogen production is approximately 25% lower compared to traditional methods that involve separate wastewater treatment and hydrogen production, assuming a green electricity cost of 0.2 yuan per kilowatt-hour [1]

Core Viewpoint - The successful operation of China's first 100 kW oil and gas associated wastewater hydrogen production system marks a significant breakthrough in the resource utilization of oil and gas wastewater, addressing key industry challenges [1][7]. Group 1: System Overview - The system, developed by China National Petroleum Corporation (CNPC) Shenzhen New Energy Research Institute and Changqing Oilfield, operates continuously and stably in the Sulige gas field [1][7]. - It features a unique dual-configuration electrolyzer design that processes high-concentration wastewater directly in a normal-pressure cell while degrading pollutants and producing hydrogen simultaneously [1][7]. - The pressurized cell is used for large-scale, high-purity hydrogen production from purified saline water [1][7]. Group 2: Performance Metrics - During the demonstration period, the system treated a total of 24 tons of wastewater, achieving a maximum hydrogen production rate of 40 standard cubic meters per hour [1][7]. - The hydrogen purity reached 99.99%, and the chemical oxygen demand (COD) removal rate of the wastewater was as high as 99% [1][7]. Group 3: Economic Impact - Under the condition of green electricity costing 0.2 yuan per kilowatt-hour, the levelized cost of hydrogen production is approximately 25% lower compared to the traditional method of "treating wastewater first, then producing hydrogen separately" [2][7].
