【Ten Years of Rapid Development in Chemical Processing Equipment】The Model 1000 alkaline electrolysis hydrogen production system achieved stable operation in extreme cold conditions from 1377 to 2024

Thread Content

Recently, the first set of Type 1000 alkaline electrolytic hydrogen production systems independently developed by the Aerospace Engineering Company completed a 36-hour continuous operation test in extreme cold conditions at the Cangzhou test site, producing hydrogen with a purity level of 5N (high purity). This marks the passing of this equipment’s tests regarding stability and safety, enabling its use in industrial production. It also indicates that the aerospace engineering company possesses the comprehensive capabilities to research, design, manufacture, and operate large-scale alkaline electrolytic hydrogen production systems for industrial use, which is of great significance for promoting green and low-carbon development in our country. The alkaline electrolysis water hydrogen production technology is a large-scale cubic alkaline electrolytic hydrogen production system that has been developed by the aerospace engineering company. Building on China’s successful achievements in life support technologies for space stations, as well as its years of experience in engineering technologies in the chemical industry, this system was refined over more than a year to meet the standards of chemical engineering design and safety evaluation criteria. This product integrates space station life support technologies with chemical engineering design principles to the greatest extent possible. It breaks through traditional limitations in areas such as flow/heat fields, structural sealing, corrosion and insulation protection, and system flexibility design. Strict HAZOP analysis and SIL grading are applied to ensure safety. In operating conditions using conventional electrodes and diaphragms, the current density reaches 3100 A/m2 at 1.98 V, and its overall performance indicators are at an advanced level in the industry. Green hydrogen engineering technology is a strategic emerging business area in the aerospace engineering company’s 14th Five-Year Development Plan. Against the backdrop of the \"dual carbon\" strategic goals, hydrogen, as a clean and low-carbon energy source, serves as a key tool for the chemical industry to achieve deep decarbonization.
