What if the key to unlocking low-carbon, nitrogen-rich fertilizer came to you in a flash? That’s exactly what happened to ARPA-E awardee Nitricity, who developed a way to create their own lightning that separates nitrogen from the air with practically zero carbon dioxide (CO2) impact.

Over the past several years, ARPA-E has funded a number of fusion “capability teams” through the Fusion Diagnostics “Exploratory Topic” (2019) and the BETHE program (2020) to accelerate fusion-energy R&D via public-private partnerships. These capability teams, drawing predominantly from federally funded researchers at U.S.

Today, the U.S. Department of Energy’s (DOE) Advanced Research Project Agency-Energy (ARPA-E) announced it selected four projects to receive a combined $9.4 million to develop technology focused on removing sulfur hexafluoride—a significantly more potent greenhouse gas than carbon dioxide—from the U.S. power grid. The four projects selected to receive funding include the University of Connecticut in Storrs, Conn.; Georgia Tech in Atlanta, Ga.; GE Grid Solutions, LLC in Charleroi, Pa.; and Toshiba International Corporation in Houston, Texas.

On August 17, 2021, a New York Times article proclaimed a fusion energy release of 1.3 megajoules from 1.9 megajoules of incident laser energy, achieved at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory. The announcement of such a significant physics result rocked the fusion world, renewing discussions on R&D to enable commercially viable embodiments of laser-driven inertial confinement fusion (ICF).

by Nicholas Rodricks, ARPA-E Summer Scholar Trash has a way of going unnoticed. Whether an apple core, a bag of chips, or an old microwave, we give little thought to throwing away everyday items. In reality, our trash’s journey is only just beginning when we throw it in the garbage. The quantity of our garbage is staggering, and with concerns around pollution and storage, the U.S. still struggles to answer the question “where should it all go?”

Earlier this year, ARPA-E announced funding for a range of the most innovative and unconventional ideas across the energy technology spectrum, exploring high-risk R&D that could lead to the development of disruptive technologies. The topics explored under this opportunity are not part of existing ARPA-E programs, but if successful could establish new program areas for ARPA-E to further explore.
