新疆100MW/400MWh钒液流电池储能项目并网投运

Core Viewpoint - The successful commissioning of the Hami Shichengzi 100MW/400MWh vanadium flow battery energy storage project marks a significant advancement in renewable energy storage in Hami, providing stable and efficient power regulation support for the "Xinjiang Power Transmission" channel [2]. Group 1: Project Overview - The Hami energy storage project utilizes an innovative "photovoltaic + storage" collaborative model, allowing for flexible adjustment of power through a "charging - discharging" mechanism, which stores excess power generated during peak solar hours for release during morning and evening peak usage times [3]. - The project is expected to enhance the renewable energy consumption capacity by 15% annually after its operation [3]. Group 2: Technology and Product Features - The energy storage system employs the TPowe r 7 series vanadium flow battery, featuring a new generation of high-energy electrolyte with a vanadium ion concentration of 2.0 mol/L, which is 20% higher than the industry average [3]. - The battery system is designed to operate in extreme temperatures ranging from -35°C to 40°C, improving its adaptability in both hot and cold regions [3]. - The high current density stack in the system achieves an energy conversion efficiency exceeding 83%, with real-time monitoring of electrolyte active ion concentration and stack health, resulting in a fault warning accuracy rate of 99.5% [3]. Group 3: Environmental Impact and Lifecycle - The project is characterized by high cyclic cost performance and long lifecycle, with the batteries not causing environmental harm upon disposal [4].
