About this opportunity
The Defense Advanced Research Projects Agency (DARPA) is soliciting innovative proposals for developing high-rate, energy-efficient, decentralized nitric acid manufacturing technologies through the High-efficiency Nitrogen Oxidation (HNO3) program. The agency seeks foundational technologies that can revolutionize nitric acid production to protect critical defense industrial base supply chains and redefine energetics manufacturing in contested logistics environments. Proposers must demonstrate revolutionary advances in science, devices, or systems, with research that goes beyond evolutionary improvements to existing practices. Evaluation criteria will focus on scientific and technical merit, potential contribution to DARPA's mission, cost and schedule realism, and technology transition capabilities. Key submission deadlines include an abstract due date of December 18, 2025, and full proposal submissions due by February 5, 2026.
The program anticipates multiple awards through procurement contracts, cooperative agreements, or Other Transaction Agreements for Prototype, with a total program duration of 42 months structured across three phases. The research has specific performance targets, including developing catalysts and reactor designs capable of producing 1 L/day of lab-grade nitric acid in Phase 1, scaling to 50 L/day in Phase 2, with an anticipated start date of August 2026. While specific award amounts are not explicitly stated, similar DARPA Research and Technology Development programs typically offer funding ranges between $100,000 and $2.8 million, with performance periods of 12-36 months. The research will be conducted at the awardee's facilities, with potential independent verification and validation by government teams.
Synopsis
The Defense Advanced Research Projects Agency (DARPA) is soliciting innovative proposals in the foundational technologies to enable high-rate, energy efficient, decentralized nitric acid manufacturing to protect critical supply chains in the defense industrial base and redefine energetics manufacturing in contested logistics environments. Proposed research should investigate innovative approaches that enable revolutionary advances in science, devices, or systems. Specifically excluded is research that primarily results in evolutionary improvements to the existing state of practice.
