Grant Opportunity Analysis

The Defense Advanced Research Projects Agency (DARPA) is soliciting innovative proposals for the High-efficiency Nitrogen Oxidation (HNO3) initiative, aimed at developing decentralized nitric acid manufacturing technologies. This program seeks to address vulnerabilities in current production methods by enabling high-rate, energy-efficient nitric acid production from air and water, thereby enhancing the resilience of critical supply chains in the defense industrial base. Proposals should focus on revolutionary advancements in catalysts and reactor designs, with an emphasis on scalability and risk mitigation, culminating in a field demonstration of a full-scale prototype. Interested parties must submit their proposals by February 5, 2026, and can contact the BAA Coordinator at HNO3@darpa.mil for further information. Additional details can be found on the SAM.gov Contract Opportunities website.
