Energy storage technology can help power systems more easily respond to strain during large-scale drains on the power grid as well as potentially lowering the carbon footprint of an energy network by charging during off-peak times and releasing the energy back to the grid when needed.

It could also support increased use of renewable energy, which is key to helping China achieve its carbon peak and carbon neutrality goals which are currently set for 2030 and 2060 respectively.

A flow battery is one in which two liquids are separated by a membrane and circulated in order to enable ion exchange between them. They typically offer a long cycle life and are suited for consistent energy delivery which is required for grid-level storage solutions.
