Are flow batteries intrinsically linked?

Because of the specific technology, stored energy in and power supplied by flow batteries are not intrinsically linked. This feature makes them especially suitable for storage systems for renewables, especially for uses with long discharge times.

What is a Technology Strategy assessment on flow batteries?

This technology strategy assessment on flow batteries, released as part of the Long-Duration Storage Shot, contains the findings from the Storage Innovations (SI) 2030 strategic initiative.

Should flow batteries be considered a growing technology?

Flow batteries should be considered a growing technology: further developments are needed to reduce costs and increase overall efficiency in order to rise to lithium system standards. A drop in prices in the last decade has led to the widespread diffusion of lithium batteries in storage systems.

Why do flow battery developers need a longer duration system?

Flow battery developers must balance meeting current market needs while trying to develop longer duration systems because most of their income will come from the shorter discharge durations. Currently, adding additional energy capacity just adds to the cost of the system.

How much power does a redox flow battery produce?

The project involves the construction of an energy storage facility with a power output of 800 MW and a capacity of 1600 MWh. These parameters are unmatched both in Europe and globally. For comparison, the currently largest operational redox flow battery is in China, with 175 MW of power and 700 MWh of capacity.

Is a flow battery safer than a lithium ion battery?

In terms of safety, a flow battery has an operating system with fewer critical issues to manage than a lithium ion battery, which needs several control systems to avoid harmful overloading and overheating. Because of the specific technology, stored energy in and power supplied by flow batteries are not intrinsically linked.
