On June 9, it was learned from the Inner Mongolia Zhunger Economic Development Zone that China's first "green power + large-capacity energy storage + energy and chemical plant" integrated coupling major technology demonstration device has achieved stable operation in Zhunger Banner. This set of technology integration broadens the application boundary of new energy storage technology, fills the gap of large-capacity energy storage technology in the field of coal chemical industry, and provides a replicable technical paradigm for the high-end, diversified and low-carbon development of energy and chemical industry.

The core of this technology integration is the successful integration of photovoltaic power generation, all-vanadium flow battery energy storage and coal chemical production system.

The traditional coal chemical industry has long been mired in the development dilemma of high energy consumption and high emissions, and the birth of this demonstration device is a breakthrough move. The core of this technology integration is the successful integration of photovoltaic power generation, all-vanadium flow battery energy storage and coal chemical production system.

"The photovoltaic power generation is directly supplied to the chemical plant after the voltage transformation, and the excess power is stored in the energy storage device and released at the peak of electricity consumption at night. The energy storage device acts as a 'power steward', accurately regulating the power supply and ensuring the stability of electricity consumption in chemical production. Its technological breakthroughs are exemplary in the industry. Wang Tanghe explained. At present, the project has achieved 100% self-consumption and full consumption of green electricity, and the proportion of green electricity consumption exceeds 25%.

As the first demonstration device in China to realize the deep integration of photovoltaic, energy storage and chemical technology, its technological breakthrough can be called an industry model. "The biggest innovation of the project is that it overcomes the contradiction between the volatility of green electricity and the stable demand for electricity in chemical production," said Wang. "By optimizing the power engineering design and integrating the advanced power management system, the device not only ensures the safe and stable operation of the chemical plant, but also achieves three key breakthroughs, the first safe and stable coupling technology of green electricity, energy storage and chemical production system, and the construction of a standardized management system for the coupling of coal chemical industry and new energy.(This article is from the official website of Seetao www.seetao.com.
