Zhong Yang Ji Wei Guo Jia Jian Wei Wang Zhan·2025-08-25 00:16Core Viewpoint - The Daan Project by State Power Investment Corporation demonstrates a sustainable method for ammonia production using renewable energy, significantly reducing carbon emissions compared to traditional fossil fuel methods [10][11]. Group 1: Project Overview - The Daan Project commenced construction in May 2023 and was completed and put into operation on July 26, 2023 [10]. - It utilizes 800 MW of renewable energy generation capacity (700 MW wind and 100 MW solar) to produce 32,000 tons of green hydrogen and 180,000 tons of green ammonia annually, saving approximately 230,000 tons of standard coal and reducing carbon emissions equivalent to the annual electricity consumption of 500,000 households [10][11]. Group 2: Industry Context - China's renewable energy sector is rapidly growing, with projected cumulative installed capacity reaching 1.41 billion kW by the end of 2024, contributing over 60% to the growth in electricity generation [11]. - The Daan Project aims to address the mismatch between renewable energy generation and grid consumption capacity, particularly the challenges of "curtailment" during peak generation periods [12]. Group 3: Technological Innovations - The project integrates a full industrial chain from "green electricity to green hydrogen to green ammonia," overcoming technical challenges in energy conversion and storage [13][14]. - It employs a combination of alkaline and proton exchange membrane (PEM) electrolysis technologies for hydrogen production, achieving a 10% reduction in overall electricity consumption compared to traditional methods [16][17]. - The project features the world's largest solid-state hydrogen storage system, allowing for safe and efficient long-term hydrogen storage [17][18]. Group 4: Operational Efficiency - A flexible control system has been developed to optimize the entire production process, enhancing the efficiency of renewable energy utilization and addressing the variability of renewable sources [20][21]. - Since its launch, the Daan Project has produced over 1,900 tons of green ammonia, showcasing its operational success and potential as a replicable model for renewable energy integration [21].
