Core Viewpoint - The successful integration of the "Wind-Solar-Storage" green low-carbon energy supply project at Jiangjing Special Steel Company marks a significant step towards achieving China's dual carbon goals, showcasing a strong collaboration between CITIC Pacific Energy and CRRC Zhuzhou Institute [3][5][7]. Group 1: Project Overview - The project features a 120MW/240MWh grid-connected high-voltage direct storage system, which is the first near-zero carbon steelmaking demonstration factory in China [3][5]. - It is expected to provide 0.75 billion kWh of green electricity annually, reducing carbon emissions by 62,400 tons [7][8]. Group 2: Technical Highlights - The high-voltage direct storage system developed by CRRC Zhuzhou Institute achieves an efficiency of over 92%, which is a 6% improvement compared to conventional low-voltage storage systems [10]. - The system can respond within 20ms to stabilize voltage and frequency during high-load operations, ensuring continuous production [11][12]. Group 3: Economic Benefits - The project is projected to generate an additional revenue of approximately 48 million yuan over its lifecycle due to reduced construction and equipment investment [10]. - The integration of the storage system is expected to enhance green electricity consumption by 168 million kWh annually, providing both visible and hidden economic benefits [15]. Group 4: Future Prospects - CRRC Zhuzhou Institute aims to replicate the successful model of Jiangjing Special Steel in more industrial parks, enhancing the capabilities of "park autonomy + multi-energy collaboration + carbon accounting" [16]. - The company plans to deepen the innovation and application of grid-connected storage technology to contribute to energy structure transformation and industrial decarbonization [18].
