Energy Storage

Growing Demand for Energy Storage

Energy storage is a crucial tool for enabling the effective integration of renewable energy and unlocking the benefits of local generation of a clean, resilient energy supply.

Energy Storage Deployments


“The stationary energy storage opportunity is massive… and virtually untapped”

Goldman Sachs, The Great Battery Race

The Flow Battery Solution

A flow battery is an electrical storage device that is a cross between a conventional battery and a fuel cell. Liquid electrolyte of metallic salts is pumped through a core that consists of a positive and negative electrode, which is separated by a membrane. The ion exchange that occurs between the cathode and anode generates electricity.

One of the main advantages of flow batteries is that energy is stored as a liquid in separate tanks,
unlike Li-ion batteries that store energy in the electrodes. The decoupling of energy and power
enables high application versatility and flexible system design according to consumer needs.

How does a redox flow battery work?

“Flow batteries are very useful for large industry and could last for decades and the rechargeable electrolyte liquid could last indefinitely (unlike lithium- ion batteries)”

Bill Gates, Energy Innovation, November 2015

Bromine Based Flow Batteries

Br-based flow batteries provide a low cost, long life and long duration energy storage solution.

Cycle Life

Bromine – based flow batteries have no loss of storage capacity over their lifetime

A Wide Range of Energy Storage Applications

Working with bromine

Working with Bromine presents a number of challenges. All the challenges including safety, reactivity and corrosiceness, can be controlled by adding a bromine complexing agent (BCA) to the electrolyte blend.

The solution has been evaluated by DNV laboratories as achieving better and safer design, making this battery a chosen, risk-free energy storage alternative that is safe enough to use in consumer homes and densely populated areas.
