2014 Storage Plan Assessment Recommendations for the U.S. Department of Energy

Posted: September 25, 2014 - 17:00 / DOE EAC / Reports

This report, approved at the September 2014 EAC meeting, summarizes a review of DOE’s energy storage program strategies and activities, and includes recommendations that the Electricity Advisory Committee (EAC) offers for the DOE’s consideration as it continues to develop and implement its energy storage program.

For its 2014 review, the EAC continues to focus on the programs and initiatives of OE, but has expanded its scope to also include additional DOE offices, namely, Office of Science, Energy Efficiency and Renewable Energy (EERE), and Advanced Research Projects – Energy (ARPA‐E), and also other federal agencies such as the Department of Defense (DOD). This expanded scope is in line with the scope of agencies included in the recent overall departmental strategy laid out in a DOE report entitled “Grid Energy Storage” in December 2013, although the focus of the 2014 EAC assessment was limited to electricity energy storage.

The recommendations include several areas where programs and initiatives could be amended, refocused, augmented, or scaled back in order to better meet the objective of the Department and the strategic goals enumerated in the 2013 DOE Report. They include more grid‐focused research support needed through the Office of Science, the National Science Foundation, or other venues, as well as continued funding, through public-private partnerships, of storage demonstration projects after ARRA funds have been expended. The EAC also recommends that inter‐agency coordination around energy storage be made more transparent and that such coordination be augmented and strengthened.

The EAC recommendations also include suggestions for several areas in which to focus research or assessment efforts, including applications for storage interconnecting at the distribution level, pumped hydro (PHS) and compressed air (CAES) energy storage technologies, power electronics costs, and regulatory and market designs and their effects on storage.

For more information on how OE performs research and development on a wide variety of storage technologies, including batteries, flywheels, electrochemical capacitors, superconducting magnetic energy storage (SMES), power electronics, and control systems, visit the Energy Storage Program page.
