The need for large scale storage solutions come to the forefront as a means to adjust supply to demand on the electrical grid. Energy storage systems can adjust time of delivery to eliminate the need for peaker plants, allow for the addition of intermittent renewable energy sources such as wind and solar, or allow for large users to reduce facility operating costs by using a storage system to supplement energy supply reducing peak demand, most notably for summer A/C loads in buildings.
Out of engineering research laboratories in materials science and electro-chemistry are coming new energy storage systems designed for the future to solve these issues meanwhile opening up new enterprises and industry. The characteristics of an ideal flow battery would include: a long service life, modularity and scalability, no standby losses, chargeability, low maintenance, and safe. In addition a flow battery will have to be economic compared to other systems which will need to be determined using LCOE analysis.
