China's Renewable Energy-Based Hydrogen Production Accelerates Large-Scale Development

[SMM Hydrogen Energy News: World's First 5 MW AEM Hydrogen Production System Commissioned, Intelli Provides Core Rectification Equipment] Recently, the world's first 5 MW anion exchange membrane (AEM) water electrolysis hydrogen production system completed installation and commenced commissioning, marking the official entry of megawatt-scale AEM technology into the industrial application stage. The project innovatively established an integrated "PV—AEM hydrogen production—blast furnace hydrogen-rich smelting" system. The green hydrogen produced will be used for hydrogen-rich injection in the steel group's blast furnaces, facilitating coal reduction and carbon reduction goals. The core rectification equipment for the system was provided by Hubei Intelli Electric, configured with 5 sets of IGBT rectifier power supplies, featuring advantages such as high power factor, low harmonics, and fast response. It can precisely match large power AEM electrolysis cells, providing reliable power supply assurance for stable system operation.

[SMM Hydrogen Energy News Brief: China's First Million-Cubic-Meter-Level Salt Cavern Hydrogen Storage Demonstration Project Put into Operation in Henan] On April 25, China's first million-cubic-meter-level salt cavern hydrogen storage demonstration project, led by the Wuhan Institute of Rock and Soil Mechanics under the Chinese Academy of Sciences, was officially put into operation in Pingdingshan City, Henan Province. This project marked China's first hydrogen storage facility built in bedded salt rock formations, identifying the multi-scale migration patterns of hydrogen in ultra-low-permeability rock salt, overcoming the core technology of precise site and layer selection for salt cavern hydrogen storage, and effectively verifying the long-term sealing performance and engineering application feasibility of hydrogen storage in bedded salt rock.

[SMM Hydrogen Energy Brief: Two Group Standards for New Energy Hydrogen Production Officially Released and Implemented] It was learned on April 1 that two group standards in the field of new energy hydrogen production, led and compiled by the Xinjiang Design Branch of the Pipeline Design Institute and jointly co-compiled by 16 industry entities in China, had been officially approved, released, and implemented by the Standardization Working Committee of the China International Association for Promotion of Science and Technology. The two standards released are "Safety Technical Guidelines for Water Electrolysis Hydrogen Production Plants" and "Economic Operation Indicators and Calculation Methods for Water Electrolysis Hydrogen Production Plants," which will provide normative references for safe operations, economic operation, and indicator accounting in the water electrolysis hydrogen production industry.
