Summary
The 2025 ARPA-E Energy Innovation Summit in the United States displayed a variety of energy research projects that the agency had funded.
Four innovations included a new means of producing steel that reduces greenhouse gas emissions, using geologically produced hydrogen to produce fuel and chemicals, high-powered magnets for electric motors that do not require rare earth materials and cheaper sodium-ion batteries to support data centres.
The innovations aimed to reduce the dependency on rare and increasingly expensive materials, streamline processes to be more environmentally friendly and boost efficiency and output in various areas of energy production and consumption.
Advanced transmission technologies were also discussed as a potential solution to the current permitting challenges faced by renewable energy projects.
