Bloomberg reports on how the world’s leading independent gas and oil storage company Royal Vopak signs a Joint Development Agreement with Elestor to develop and scale large-scale hydrogen bromine flow batteries.
The joint ambition is to scale up the electricity storage capacity of these flow batteries from 200 kWh to 3,000 kWh before developing it to industrial scale. “This development is part of Vopak’s New Energy strategy,” says Patrick van de Voort, Division President Europe & Africa at Vopak. “Developing large-scale and low-cost electricity storage will become increasingly important and with this promising technology electricity can be stored in molecules on a large scale. We are looking forward to jointly developing these flow batteries.”
