Core Viewpoint - The Huadian Group's Mu Lei carbon dioxide storage project has successfully completed the main structure, marking a significant step towards establishing the world's largest carbon dioxide storage project, which will support large-scale wind and solar energy bases in desert and arid regions [1]. Group 1: Project Overview - The project is located in the Changji Hui Autonomous Prefecture of Xinjiang, with a planned capacity of 600,000 kW of wind power, 400,000 kW of solar power, and 1,000,000 kWh of storage [1]. - It features a compressed carbon dioxide storage system with an 8-hour storage duration and a 10-hour power generation duration, utilizing a non-combustion compressed carbon dioxide storage technology [1]. Group 2: Advantages of Carbon Dioxide Storage - The carbon dioxide storage system offers several advantages, including large capacity, long duration, and safety, making it suitable for various storage scenarios [5]. - It operates in a closed system, minimizing environmental impact and avoiding the generation of pollutants, with no special geological conditions required for site selection [5]. - The construction period is approximately 2 years, with a lifespan exceeding 30 years, and it operates with zero carbon emissions [5]. - The system maintains constant pressure throughout its operation, ensuring high efficiency and the ability to quickly respond to grid demands, providing ancillary services such as frequency regulation and peak shaving [5]. Group 3: Industry Context - The project aligns with recent developments in Xinjiang, where two major storage projects have also commenced, indicating a growing focus on energy storage solutions in the region [6].
