Future Electric Power Grid and Battery Storage

Battery technology is the most promising (besides pumped hydro) of all energy storage applications for the future power grid. With the growth of renewable energy, distributed energy resources, the number of Plug-in Electric Vehicles and more PV installations: large and small, future electric power grid is evolving into a two-way flow of information and electricity between demand and supply. This paper provides an up-to-date information on battery storage as applied to the electric power grid including the cost, technology, design and applications.
