【Ten Years of Rapid Development in Chemical Processing Equipment】Top 2000 Nm3/h High-Performance Alkaline Electrolyzers for Hydrogen Production in China from 1996 to 2023

Thread Content

Ten years of rapid development in chemical engineering equipment – praising the prosperity and strength of modern China. This is just a starting point; more participation will make things even more lively. HaiChuan becomes even better with your involvement; we welcome everyone to join in the forum discussions. Everyone should pay attention to safety and know how to handle emergencies. ********************************************* On June 11, 2023, the first “Shanghai International Carbon Neutrality Technology, Products and Achievements Expo” (hereinafter referred to as the “Carbon Expo”) was held at the Shanghai Exhibition Center on that date. SHANGHAI ELECTRIC made a stunning appearance with its four innovative products in the fields of wind, solar, hydrogen, and energy storage. Among them, the 2000 Nm3/h alkaline electrolyzer produced by Hydrogen Era Company, a subsidiary of Shanghai Electric, was officially launched. It is understood that this electrolyzer is currently the hydrogen production device in China with the highest single-unit hydrogen output; its maximum hydrogen production capacity can be increased to 2500 Nm3/h, meeting the needs of large-scale hydrogen production and utilization applications such as those in wind and solar power plants, as well as in the green chemicals/metallurgy industries. Shanghai Electric takes core materials as a starting point, and by developing new, high-performance electrode catalysts as well as next-generation separator materials, it achieves a significant improvement in the performance of its products ； The structure of the plates and frame components, as well as the surface treatment processes, were optimized. A new generation of modified sealing materials suitable for large-scale square electrolyzers was developed, thereby improving the sealing and pressure resistance capabilities of these products and extending the service life of existing hydrogen production equipment by electrolysis to over 20 years. The alkaline electrolyzer model with a capacity of 2000 Nm3/h released this time features an increased current density of 3500 A/㎡, with the DC energy consumption reduced to 4.15 kWh/Nm3H2 at 3000 A/㎡. Its overall performance has improved by 8% compared to the previous version; the production cost per cubic meter of hydrogen has decreased by 6%, and the land area required for producing the same amount of hydrogen has been reduced by 33% compared to before.
