CHINA LONGYUAN(HK:00916) Ke Ji Ri Bao·2025-09-08 00:25Core Viewpoint - The China Three Gorges Corporation has initiated the first charging experiment for its integrated photovoltaic and all-vanadium flow battery energy storage project in Xinjiang, marking it as the largest all-vanadium flow energy storage project in China [1]. Group 1: Project Overview - The project features a capacity of 1 million kilowatts of photovoltaic energy and 200,000 kilowatts/1 million kilowatt-hours of all-vanadium flow energy storage [1]. - The charging experiment aims to activate the all-vanadium flow electrolyte, enabling energy storage and release capabilities [1]. - The energy storage station consists of 80 storage units, with the initial experiment conducted on one unit, showing normal operational parameters [1]. Group 2: Technology and Advantages - The all-vanadium flow battery utilizes a "liquid storage" mode, storing energy in liquid tanks and cycling vanadium ion solutions through the battery stack to achieve energy storage and release [2]. - This technology offers three core advantages: 1. Extremely long cycle life, with up to 16,000 cycles, significantly surpassing lithium batteries' 2,000-3,000 cycles, and a stable lifespan exceeding 20 years [3]. 2. High safety due to the non-flammable and non-explosive nature of the electrolyte [4]. 3. Long-duration energy storage capability, addressing the intermittent nature of renewable energy sources like wind and solar, thus stabilizing power supply [4]. Group 3: Implications for Energy Transition - The all-vanadium flow battery's characteristics support large-scale integration of renewable energy into the grid, transforming renewable energy from a "volatile power source" to a "stable power source" [4]. - This technology is crucial for achieving China's dual carbon goals and transitioning to a clean, low-carbon energy structure [4].
