Standards for flow batteries

In 2010, the organising committee for the first IFBF conference identified the need to develop standards to support the growing flow battery industry. As a result, several companies and individuals formed a CENELEC workshop and CWA 50611: Flow batteries – Guidance on the specification, installation and operation was published in April 2013. Building on this work many flow battery standards have since been approved and published. 

Below is a list of national and international standards relevant to flow batteries. Care has been taken in the preparation of this information, but it is not necessarily complete or comprehensive. We thank Jens Noack of Fraunhofer ICT for collating this information and making it available to the IFBF.

The IFBF encourages all those in the industry to take an active interest in the development of standards, not only for flow batteries, but also those relating to other forms of electrical energy storage and associated equipment. If you wish to participate, you should contact your national committee for standards for further information.
