The Department of Defense (DOD) is seeking innovative solutions for a regenerable CO2 scrubbing system to enhance the performance of self-contained breathing apparatuses (SCBAs). The objective is to develop a continuously regenerable system that significantly reduces the weight and heat generation associated with current CO2 removal methods, thereby extending the operational lifetime of SCBAs used in hazardous environments. This technology is crucial for military operations that require prolonged use in immediately dangerous to life and health (IDLH) atmospheres or unknown CBRN environments. Interested parties should note that the solicitation is set to open on January 29, 2025, with applications due by February 26, 2025, and can find more information at the DOD SBIR website.
