ARPA-E’s impact assessment initiative documents the scientific and commercial successes achieved by a selection of ARPA-E-funded projects. The third installment of this series, “ARPA-E Impacts: A Sampling of Project Outcomes, Volume III” provides a glimpse into the diverse and sophisticated research portfolio of advanced energy technologies that will enable the United States to tackle our most pressing energy challenges.

Recent advances in wide band-gap (WBG) semiconductor materials, such as silicon carbide (SiC) and gallium nitride (GaN) are enabling a new generation of power semiconductor devices that far exceed the performance of silicon-based devices. Past ARPA-E programs (ADEPT, Solar ADEPT, and SWITCHES) have enabled innovations throughout the power electronics value chain, especially in the area of WBG semiconductors.

ARPA-E’s RANGE (Robust Affordable Next Generation Energy Storage Systems) program funded high-risk research projects to change the way electric vehicle battery systems are built. The program is a success both in terms of individual projects and in reshaping the paradigm about energy storage as a whole to include system-level considerations.

The Agency’s first compilation booklet of impact sheets, published in 2016, began the process of analyzing and cataloging some of the agency’s most successful projects. One year later ARPA-E’s research investments continue to pay off, with a number of current and alumni project teams successfully commercializing their technologies and advancing the state of the art in transformative areas of energy science and engineering. This document is a compilation of the second volume of these impactful technologies.
