Leidos Holdings IncLeidos demonstrated a regenerative fuel cell prototype under DARPA's ExCURSion program, advancing a closed, rechargeable system for energy storage.

Leidos has demonstrated a working cell prototype under DARPA's Expeditionary Carbon Utilization for Energy Resilience and Stabilization program that cycled up to 1,000 times in testing, advancing a closed, rechargeable system designed to store energy as carbon-based fuel. The ExCURSion program aims to eliminate the tradeoff between batteries and fuel by integrating carbon combustion, capture, and regeneration into a single platform, with the goal of producing fuel on demand from inputs such as carbon dioxide, water, and electricity. Leidos' approach relies on high-rate carbonate reduction processes in engineered electrolytes and advanced materials that shuttle critical chemical species between electrodes. The intended operational benefits include fewer fuel convoys, reduced exposure to threats, and improved mission endurance, while also reducing dependence on certain critical minerals and traditional fossil fuels. The work is supported by DARPA under Contract No. HR001125C0012.
