the electric energy is steadily "loaded" into the aqueous solution, the low-valley energy storage and the peak discharge can completely bid farewell to the potential safety hazard of traditional energy storage-this new energy storage technology, which sounds full of scientific and technological sense, has come true in Suqian, Jiangsu Province.

recently, the first domestic water system organic liquid flow battery station energy storage project was officially put into operation in Suqian economic development zone and landed in Chuzhou, Anhui province simultaneously. it not only fills the technical gap of distributed new energy consumption and distribution network optimization, but also creates a replicable and popularized "Suqian model", unlocking a safer, more environmentally friendly and more efficient energy storage path for the construction of new power system.

Say goodbye to flammable risks! "Water storage", intrinsic safety break

At present, distributed photovoltaic is rapidly popularizing, rural and urban distribution networks often face voltage instability, photovoltaic consumption difficulties, load fluctuations and other pain points, Taiwan energy storage has become the key to balance the power grid, invigorating green electricity. However, the traditional energy storage scheme has many security risks, it is difficult to adapt to residential areas, Taiwan and other dense scenes all-weather stable operation needs.

the core of the "water storage and electricity storage" project put into operation in Suqian adopts the independent research and development of water-based organic liquid flow battery technology, which completely breaks out of the limitation of traditional energy storage: neutral aqueous solution is used as electrolyte to replace the common strong acid system in the industry, and the electrolyte is non-flammable, non-toxic and non-corrosive in case of open flame, thus realizing intrinsic safety. At the same time, the electrolyte can be recovered and recycled, it perfectly fits the reliability and all-weather operation requirements of energy storage in the Taiwan area.

The actual effect is bright! The photovoltaic consumption rate exceeds 98%, the power grid is more stable and the power supply is more smooth

the project is jointly developed by Suqian's local enterprise, the United Nations network electric academy, and a number of core technological breakthroughs have been achieved. after landing, the results are very outstanding.

through the coordinated control of optical storage and charging, the project effectively solves the problem of distributed photovoltaic local consumption, and the photovoltaic consumption rate in the demonstration area is directly increased to more than 98%. At the same time, seamless switching between grid connection and off-grid is supported. When the main network fails, it can fully guarantee uninterrupted power supply for critical loads, help realize "zero stop sensing", greatly optimize the operation stability of distribution network, and alleviate common problems in industries such as voltage exceeding limit and load overload.

from pilot to replication, Suqian seizes the new track of energy storage industry

as the first energy storage project of this type in the country, its significance is far more than a technology landing, but also an important breakthrough in the landing of the industry. The project successfully verified the applicability of water-based organic liquid flow battery in microgrid and station scenes, opened up the whole chain from laboratory research and development to engineering application and then to cross-provincial replication, and changed the cutting-edge technology from "pilot bonsai" to "promotion scenery".

in recent years, Suqian has continued to develop a new energy storage industry, promoting the deep integration of innovation chain and industrial chain with policy empowerment, leading drive and chain layout. in 2025, the output value of the city's energy storage industrial chain has exceeded 30 billion yuan, becoming a strong

for the high-quality development of regional new energy industry
