For the most part hydrogen peroxide is produced on a large scale in centralized chemical plants, generally from oxygen and hydrogen and with a catalyst made of expensive platinum. As hydrogen peroxide can decompose spontaneously in highly concentrated solutions and explode, it can only be transported as a hazardous substance subject to strict safety precautions. This substantially increases the transport costs.

The Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB has developed and implemented a new technical concept where hydrogen peroxide is generated locally and on the basis of demand in an electrochemical cell, that means with electricity alone – just from air and water. As a result of the turnaround in energy policy, there are non-uniform spikes in current supply from the regenerative production of energy. Thus the electrolytic production of chemicals is both becoming cost-effective and represents – in addition to the storage of energy – a practical utilization pathway for balancing out spikes in current supply to the grid.
