The US Department of Energy (USDOE) will be providing up to $30m in funding for the projects that are part of the Advanced Research Projects Agency-Energy (ARPA-E) programme called Duration Addition to Electricity Storage (DAYS).

The project teams under the DAYS will be engaged in the development of new technologies that will enable long-term energy storage on the power grid.

US Secretary of Energy Rick Perry said: “Building the grid of tomorrow will require new tools and technologies to ensure Americans have access to affordable and secure energy.

“At DOE, we are peering over the energy horizon and identifying the key technologies we need to support the power system of the future.

“These new storage options will offer us the opportunity to make the grid more resilient while enabling greater integration of our domestic energy resources.”

The DAYS teams have to design and develop cost-effective energy storage systems that can be deployed at any given location.

USDOE explained that the funding opportunity is not confined to any one particular technology.

The participating teams also have the option to develop energy storage systems using thermal, mechanical, or electrochemical power technologies.
