Before its annual Energy Innovation Summit in 2013, the Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) announced funding for a new program aimed at rethinking electric vehicle (EV) batteries. The program, Robust Affordable Next Generation Energy Storage Systems or RANGE, was created as part of an integrated effort to accelerate electric vehicle innovation to reduce costs and improve performance of EVs. Last week, ARPA-E announced the names and descriptions of the 22 recipients for the RANGE program, representing fresh approaches to making EVs available to everyone.

ARPA-E has invested in transportation technologies since its creation. The new RANGE program complements the agency’s BEEST program for doubling the energy density of EV batteries by altering battery composition and materials, AMPED for seeking advanced power management technologies for storage, and GRIDS, for developing cheap utility scale storage. The RANGE program is a genuine reflection of these previous ARPA-E’s programs as it supports truly far-reaching innovations and revolutionary energy technologies.

The program recognizes that significant breakthroughs in battery chemistry and vehicle architecture are crucial for EVs to compete with internal combustion vehicles. In response, most of the RANGE projects consider alternative materials for batteries that are lighter than existing batteries, safer in the case of collision, and don’t rely on foreign-sourced rare materials. We spoke with Dr. Cheryl Martin, Deputy Director of ARPA-E, about the new program, which she described as the agency’s “twist on improving the EV battery space.”
