About Elestor

Recognized with several national and international awards, Elestor is a fast-growing company, developing a revolutionary low-cost flow battery, thereby reducing the costs for storing electricity to an absolute minimum. To realize this, low cost and abundant active materials (hydrogen and bromine) are selected as well as a compact and easy to manufacture cell, and a (patented) pressurized system design. This triple cost reduction strategy results in the lowest possible cost for storing electricity.

Since 2016, several pilots on limited scale have been successfully operational in the field, and the first systems on actual container scale are currently built, in anticipation of commercial launch in 2021.

Elestor has the technology to play a decisive role in realizing the transition towards a 100% clean electricity supply. The market pull for Elestor’s technology is concrete and growing very fast, and launching customers have already been identified. Once commercially launched, Elestor envisions building a ‘Giga factory’ scale equivalent for flow batteries.

Elestor is well funded for growth with a recent multi-million Euro investment from Koolen Industries, along with a significant additional investment from InnoEnergy, one of the early investors of Elestor.
