Technical FAQs 4

What is the current kWh cost of flow batteries?

From the perspective of construction cost, commercialization, safety battery recycling and electromotive cost, it can be seen that the current kWh cost of flow batteries is relatively advantageous. The kWh cost of batteries (full life cycle) is now below 0.3 RMB/kWh.

Why is a flow battery important to China's Energy Future?

It also plays an important role in regulating energy supply and frequency, making it a key component of China’s sustainable energy future. Rongke Power, a pioneer in flow battery technology, previously developed the 100 MW/400 MWh Dalian system in 2022, the largest of its kind at the time.

What is Xinjiang's longest-duration flow battery?

The 200MW/1GWh vanadium flow battery system, built with the participation of Dalian Rongke Power Co., Ltd., marks a historic milestone — ushering in the GWh era for flow battery technology. With a maximum energy storage duration of 5 hours, the project sets a new benchmark as Xinjiang’s longest-duration flow battery energy storage facility.
