The US DOE made two smart grid-related funding announcements yesterday, one on $30 million for long duration energy storage and the other on $68.5 million for advanced research on EVs. The energy storage funding comes under a new Advanced Research Projects Agency-Energy (ARPA-E) program called Duration Addition to Electricity Storage (DAYS, with the "Y" reflecting the "y" in "electricity").
DAYS project teams will build innovative technologies to enable long-duration energy storage on the power grid, providing reliable electricity for 10 to approximately 100 hours, DOE said. Energy storage will play an increasingly critical role in the resilient grid of the future and storage systems provide important services, including improving grid stability, providing backup power, and allowing for greater integration of renewable resources, it added.
Today's dominant storage options have limitations that inhibit their use as long-duration solutions, particularly their high cost, the agency said. DAYS teams will develop energy storage systems that are deployable in almost any location and discharge electricity at a per-cycle cost target much lower than what is possible in systems available today, it added.
The funding opportunity is open to a range of storage technology choices including thermal, mechanical, electrochemical, chemical, and others. Driving the challenge are an aggressive set of cost targets, siting, power output, and duty cycle requirements, DOE said.
The $68.5 million is for early-stage research of advanced vehicle technologies to enable more affordable mobility, strengthen domestic energy security, and enhance US economic growth, it added.
Funded through DOE's Office of Energy Efficiency & Renewable Energy, projects selected through this Vehicle Technologies Office funding opportunity will address priorities in advanced batteries and electrification including cybersecurity related to EV charging; materials for both lighter weight vehicle structures and advanced powertrains; technology integration and energy-efficient mobility systems; and engines and fuels, including technologies for off-road applications as well as the co-optimization of engines and fuels, DOE said.
