EDF evaluates new battery technology


Electricite De France (EDF) has just entered into an evaluation agreement in an effort to evaluate new battery technology to enable greater stationary storage for renewables.

The testing and evaluation of the technology, based on Prussian Blue analogue electrodes and a sodium-ion electrolyte, will be conducted at EDF’s state-of-the-art battery test laboratories in France.

Prussian Blue dye, commonly used in blueprints, is very effective in storing and releasing energy in the form of sodium ions. Its widespread availability, low cost and low sensitivity to temperature extremes, make this environmentally friendly technology a potential game-changer for sustainable energy storage solutions.

“EDF R&D and EDF Innovation Lab researchers and engineers in California are seeking innovative and high-performance storage solutions in response to EDF’s growing global storage needs. We are really excited to further evaluate and test at our facilities in France,” explained Arnaud Souille, smart grid programme manager at EDF Innovation Lab.

According to research firm IHS, the global energy storage market is growing exponentially, with an annual installation size of 6GW in 2017 expected to grow to over 40GW by 2022. It has further been reported that the US energy storage market will be worth $3.1 billion by 2022, a sevenfold increase from 2017.*
