PNNL researchers are leading and contributing to ARPA-E–funded projects focused on advancing transformational energy technologies with the potential to strengthen U.S. energy systems, improve operational performance, and expand technological capability.

Projects span a wide range of research areas and are designed to accelerate the transition of promising technologies from concept development toward demonstration and deployment.

Artificial Intelligence

AutonomIA - This project is developing an artificial intelligence–based traffic management system that combines advanced sensing, adaptive traffic signals, and connected automated vehicles. The technology is designed to reduce traffic congestion and energy use across regional transportation systems, demonstrating measurable improvements over today’s traffic management approaches.

Rapid Artificial Intelligence–Based Geophysical Imaging and Advanced Visualization - This project uses artificial intelligence to rapidly create detailed underground maps and digital models that help identify buried infrastructure. By improving the speed and accuracy of subsurface imaging, the technology can support safer and more efficient planning for underground energy projects.

Fusion and Advanced Energy Systems

Ferritic and Vanadium Alloys with Nanoparticle Strengthening for Fusion - This project is developing advanced structural materials capable of withstanding the extreme conditions within future fusion energy systems. Stronger, more durable materials can help improve reactor performance and support the development of commercially viable fusion energy technologies.

Advanced Materials and Manufacturing

Additive Friction Surfacing for Large-Scale Additive Manufacturing with Improved Service Life in Extreme Environments - This project advances a solid-state manufacturing process that produces stronger, longer-lasting components for demanding operating environments. The approach has the potential to improve manufacturing efficiency while extending the service life of critical infrastructure and equipment.

Transportation Systems

Optimal Global Platform for Transportation - This project is creating a decision-support tool that helps prioritize technology and fuel investments across road, rail, and water transportation. By improving freight planning across multiple transportation modes, the platform can increase efficiency and support more informed infrastructure investment decisions.

Energy Resources and Critical Materials

Exploring Macroalgae as Critical Mineral Crops - This project pioneers a sustainable approach for recovering valuable rare earth elements and platinum group metals from marine macroalgae. By recycling extraction chemicals, preserving algae for future use, and developing new materials that selectively capture valuable metals, the technology improves resource efficiency while reducing waste.

Supercritical Carbon Dioxide–Based Mining - This project is developing a new mining approach that uses supercritical carbon dioxide to recover critical minerals from low-value ore deposits while permanently storing carbon dioxide underground. The technology aims to strengthen domestic supplies of critical minerals, lower energy costs, and reduce the environmental impacts of mineral extraction.
