Blue Battery

The Blue Battery is the only electrical storage system 100% sustainable. During the last two years spent on research, we developed an innovative product that stores electricity only using water and kitchen salt. Our invention will revolutionize the energy storage world and it will foster the growth of renewable energy technologies around the globe. We want to stop the use of toxic materials, such us the acids used to build conventional batteries. Those systems are obsolete and extremely damaging for the environment.
