Description

The energy storage addressed to electric regulation requires a large storage potential and technical solutions, none of them satisfy the whole required demands from the existing applications. The REDOX flow batteries specific characteristics of daily deep charge and discharge capability mean they are ideal for stationary applications. The main goal of the project will be to develop a Zn-Br flow battery of 60 kWh devoted to store the production excess coming from renewable energies and its integration in Smart Grids. At the end of the project, JOFEMAR will improve the components integrating the battery, its production and assembling processes, as well as the best piling and stacks configuration strategies to achieve a suitable storage potential to be integrated into a grid. These new batteries will improve the efficiency both in storage potential but also in cost. It is expected to achieve a storage system with an estimated cost of 200 €/kWh meaning a renewable energy cost reduction and accordingly a higher expansion in that which concerns its use, taking into account that the current estimation of the Lithium-Ion batteries cannot decrease under the 600 €/kWh.

Summary of project results

The main goal of the project is be to develop a Zn-Br flow battery of 60 kWh devoted to store the production excess coming from renewable energies and its integration in Smart Grids. At the end of the project, JOFEMAR have obtained a deep knowledge in that which regards the components integrating the battery, its production and assembling processes, as well as the best piling and stacks configuration strategies to achieve a suitable storage potential to be integrated into a grid. These developed batteries will improve the efficiency both in storage potential but also in cost regarding the current storage systems and related to the Vanadium flow batteries and also of the Lithium-Ion batteries. Nevertheless new development will be necessary in order to obtain an optimized battery.
