Energy Storage

Bromine-based technologies are innovative storage solutions for renewable energy sources like wind and solar

Increasing global energy demand presents huge challenges. Bromine is used in multiple energy applications, which in the long run have the ability to secure an affordable energy supply for our future.

Bromine-based storage technologies are a highly efficient and cost-effective electro-chemical energy storage solution, providing a range of options to successfully manage energy from renewable sources, minimizing energy loss, reducing overall energy use and cost and safeguarding security of supply.

Typical bromine-based flow batteries include zinc-bromine (Zn-Br) and more recently hydrogen bromide (HBr).

Other variants in flow battery technology using bromine are also under development.

Bromine-based storage technologies are typically used in stationary storage applications for grid, facility or back-up/stand-by storage.

HOW DOES THE ZINC-BROMINE FLOW BATTERY WORK?

Typical bromine-based energy storage technologies are based on redox flow (after reduction–oxidation), principles. In effect, they are a rechargeable battery consisting of one or two tanks that contain chemicals dissolved in liquids and which are usually separated by a membrane.

When the two solutions flow from one tank to the other, they generate a charge by moving electrons back and forth between the tanks, thus creating energy. A flow battery is technically similar to a fuel cell and an electrochemical accumulator cell (electrochemical reversibility).

Flow batteries can be recharged rapidly by replacing the electrolyte, which is stored outside the cell. These rechargeable batteries can be left fully discharged indefinitely.
