The Offshore Wind Innovators Awards are awards organized by TKI Wind op Zee in the Netherlands to reward innovative contributions to the offshore energy transition. Both the jury and the audience declared EIT InnoEnergy supported Elestor the winner of the Offshore Wind Innovators Awards 2022. The jury was unanimous in their top 3 with Elestor, FLASC and TechBinder. The winners show that the offshore energy sector is working hard on solutions to realize the leap forward to 21 Gigawatt of clean energy from the North Sea in 2030 and to provide our country with a constant flow of clean energy.


The jury assessed the entries on their contribution to the energy transition at sea. For example, does an innovation help to cope with the pressing shortage of personnel or does the idea contribute to a stable energy supply?

Elestor unanimous winner for the jury

“Elestor convinces with feasibility and entrepreneurship. The organization is already robust. Elestor is well advanced in the development of the flow battery with bromine and hydrogen and the practical applicability has been proven,” said the jury about Elestor.


Elestor’s idea is a power battery with hydrogen bromide. With the help of electricity, hydrogen bromide splits into hydrogen and bromine. The battery is then charged and provides power when hydrogen and bromine come back together. These raw materials are widely available worldwide – they can be extracted from seawater – and the concept can easily be scaled up to large storage parks. This makes it a robust and inexpensive way to realize energy storage.


“This makes Elestor the most credible entry when it comes to scaling up the idea to offshore industrial application, that scalability is a big plus. This is an innovative application of the flow battery, which can help accelerate offshore wind extraction.”


The audience was also very clear in their vote. About half of their votes went to Elestor.
