The first all-vanadium redox flow battery energy storage system of Huabei Oilfield has been put into operation

Recently, the No. 4 Oil Production Plant of Huabei Oilfield has successfully put into operation the first 125kW/500kWh all-vanadium redox flow battery (VRFB) energy storage system in the Langdong production area. The smooth operation of this system not only completed the charge-discharge test, but also achieved a system efficiency of over 82%, exceeding the expected design requirements, marking an important step for the plant in the field of green energy. The commissioning of the all-vanadium redox flow battery energy storage system aims to ensure the power supply stability of the 950kW distributed photovoltaic (PV) power station cluster in this area. This initiative has realized the strategic transformation from the traditional single gas-fired power generation mode to the diversified and coordinated power supply mode of "PV + gas + energy storage". This transformation not only conforms to the current global trend of green energy development, but also injects new impetus into the sustainable development of Huabei Oilfield. As an emerging energy storage method, all-vanadium redox flow battery technology has attracted widespread attention due to its excellent cycle life and high safety. Compared with traditional lithium-ion batteries, all-vanadium redox flow batteries have the advantage of being capable of large-scale energy storage, making them suitable for long-term power dispatching and large-scale applications. The successful case of Huabei Oilfield this time demonstrates the great potential of all-vanadium redox flow batteries in practical applications. The system can be dispatched for 330 days a year, meaning it can efficiently support the power grid for most of the time. This feature can not only effectively save electricity costs, but also provide a more flexible solution for power grid peak shaving. Power peak shaving is an indispensable part of modern power grid management, which can balance power supply and demand and improve the operating efficiency and stability of the power grid. This technological innovation of the No. 4 Oil Production Plant of Huabei Oilfield is a microcosm of China's continuous exploration and practice in the green energy transition. With the transformation of the global energy structure, more and more enterprises have begun to attach importance to the development and utilization of renewable energy. The successful commissioning of this system by Huabei Oilfield not only provides a new engine for enterprises to reduce costs and increase efficiency, but also sets a benchmark for the green transformation of the entire industry. With the strong support of national policies, more enterprises will participate in the development of renewable energy in the future. The promotion and application of all-vanadium redox flow battery energy storage technology will further promote the development of clean energy and help achieve the "dual carbon" goals. This goal is not only a national strategic choice, but also an inevitable choice for the sustainable development of enterprises. The commissioning of the all-vanadium redox flow battery energy storage system by the No. 4 Oil Production Plant of Huabei Oilfield has undoubtedly injected new vitality into the industry. With the continuous advancement of technology and the continuous expansion of application scenarios, we have reason to believe that in the future, this energy storage technology will be applied in a wider range of fields and contribute to the global green energy transition.
