Dutch electricity storage company Elestor bags  €30M  to boost its hydrogen bromine flow battery technology

The Netherlands-based Elestor, a large-scale electricity storage company, announced on Saturday, July 27, that it raised €30M in a fresh round of funding led by Equinor Ventures, the corporate venture capital arm of Norwegian energy giant Equinor.

The round also saw participation from the venture capital arm of independent tank storage company Royal Vopak, Dutch impact investor Invest-NL (as co-lead investor), and Somerset Capital Partners, as well as existing shareholders EIT InnoEnergy and Enfuro Ventures.

Guido Dalessi, CEO of Elestor, says, “The investment proves that we have earned the trust and support of this diverse group of highly respected investors. During the investment process, coordinated by Deloitte Corporate Finance as Elestor’s exclusive advisor, the investors have carried out a comprehensive technical and operational due diligence that has validated both our technology and our ability to deliver.”

Capital utilisation

Elestor says that the proceeds will help implement an ultra-rapid growth strategy that will accelerate the commercialisation of its proven hydrogen bromine flow battery technology up to a GW scale manufacturing facility.

Dalessi says, “We are ready to deliver exactly the kind of renewable electricity storage solutions the world is crying out for right now: Long Duration Energy Storage, or LDES. Expansion of Elestor’s production capacity and supply chain management is under control of Hylke van Bennekom (COO, Elestor), who joined the company’s management team in April 2021 through an MBI.”

Cutting the cost of electricity storage

Founded in 2014 by Wiebrand Kout, Elestor claims to have developed flow batteries using hydrogen and bromine as active materials, both available in virtually unlimited quantities.

Additionally, the idea opens up a number of fresh and distinctive integration opportunities with hydrogen infrastructures and electrolysers since the battery produces hydrogen throughout the charging process. Elestor technology, therefore, provides a link between the battery-based and hydrogen-based energy storage worlds.

Elestor says that with the use of this technology, renewable energy generated by solar or wind power plants can be stored in a reliable, scalable, cost-effective, and efficient manner.

According to Elestor, the energy transition will not only aid in the fight against air pollution and climate change, but Elestor and other climate technology firms will also produce economic development, new employment, and financial benefits for investors.
