In the study described in this paper, the authors represent the entire U.S. power generation fleet with an agent-based model that incorporates projections for future need as well as historical data on types and typical lifetimes of existing power plants.  This model was used to examine various scenarios for fusion market entry that included variations in entry date, uptake/transition rate, and final market capture fraction.

Increasing the conversion efficiency of incident solar energy to electricity is a key goal in the solar R&D community. In this issue of Joule, a conceptual hybrid photovoltaic/thermal (PV/T) receiver design is reported by the research groups of Evelyn Wang and Gang Chen. High exergetic efficiency is achieved by absorbing below-bandgap and excessively high-energy photons as thermal energy, while allowing photons at the PV’s bandgap to pass through to the underlying cell.

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.
