Core Viewpoint - The article highlights the successful launch of the Daan Wind-Solar Green Hydrogen Ammonia Integration Demonstration Project by State Power Investment Corporation, showcasing China's advancements in green hydrogen energy and its global leadership in this sector [4][6]. Group 1: Project Overview - The Daan project, located in Jilin, has a total installed capacity of 800,000 kW, consisting of 700,000 kW from wind power and 100,000 kW from solar power, along with 40 MW/80 MWh of energy storage and 60,000 standard cubic meters of hydrogen storage [4]. - The project is designed to integrate green electricity generation, green hydrogen production through water electrolysis, and green ammonia synthesis, with an annual production capacity of 32,000 tons of green hydrogen and 180,000 tons of green ammonia, resulting in a carbon reduction of approximately 650,000 tons per year [4]. Group 2: Technological Achievements - The project sets multiple global records, including the largest single green ammonia project with a capacity of 180,000 tons per year and the largest scale of alkaline and PEM mixed electrolysis for hydrogen production [4]. - The project features a proprietary "Electric-Hydrogen-Chemical" flexible control system that addresses the challenges of wind and solar variability, ensuring stable production [4]. Group 3: Key Equipment Suppliers - The project utilizes 39 sets of 1,000 Nm³/h alkaline electrolysis equipment supplied by Longi Hydrogen Energy, Sunshine Hydrogen Energy, Sany Hydrogen Energy, and Pairui Hydrogen Energy [8]. - Guohydrogen Technology provided the PEM hydrogen production equipment, successfully completing the installation and commissioning, marking a significant achievement in domestic industrial-grade PEM hydrogen production [9][11]. - In terms of hydrogen production power supply, 12 sets of IGBT hydrogen power supplies were successfully commissioned, with Sunshine Hydrogen Energy being the sole supplier for both the IGBT power supply and alkaline electrolysis systems [12][13]. Group 4: Hydrogen Storage Solutions - The project features the first large-scale application of titanium-based solid-state hydrogen storage technology in China, with a delivery of a 48,000 standard cubic meter solid-state hydrogen storage module [16]. - This technology offers several advantages over traditional high-pressure gas storage, including enhanced safety, higher hydrogen density, longer cycle life, and high purity suitable for ammonia synthesis [16].
