Innovative Energy Storage Technologies Enabling More Renewable Power

Solar and wind power provide the means for America to strengthen its energy security, create jobs in growing markets, and improve the environment. Thanks to breakthroughs in energy storage systems, including the first grid-tied solar and storage facility, that potential is getting closer to reality. By combining energy storage systems with smart grid technology, utilities are able to automatically "smooth" the output of energy. This allows intermittent energy sources to be available even when the sun isn’t shining or the wind isn’t blowing.

Across the United States, the American Recovery and Reinvestment Act funding is allowing 32 demonstration projects, including large-scale energy storage, smart meters, distribution and transmission system monitoring devices, and a range of other smart technologies, to explore the deployment of integrated smart grid systems on a broader scale.

Recently, three of these projects have been recognized for their progress in the development and implementation of energy storage systems. As the worldwide market for clean energy expands, projects like these are continuing the tradition of American leadership in developing next-generation technologies. See Energy Blog post.
