Active TRL 3 (started at 1, targeting 9)
This project focuses on developing and evaluating technologies for in situ hydrogen peroxide (H₂O₂) generation to support long-duration space missions. Hydrogen peroxide is a versatile disinfectant that can be used for surface cleaning, microbial control, and system sanitization while remaining compatible with Environmental Control and Life Support Systems (ECLSS) and safe for crew exposure.
The effort centers on electrochemical production methods that use only water, air, and electricity, eliminating the need to store and transport large quantities of consumables. Two primary approaches are being assessed: a custom-developed cell stack based on prior SBIR work and a commercially available system. Both technologies are evaluated against key performance metrics including concentration, efficiency, durability, mass, power, and volume. A down-selection process will identify the most viable approach for future flight demonstration.
Ultimately, this work aims to enable reliable, on-demand disinfectant production to reduce logistics burden and enhance sustainability for exploration-class missions, including lunar and Mars habitats.
In situ hydrogen peroxide generation provides a significant advantage for space missions by reducing reliance on resupply and enabling on-demand production of a versatile disinfectant using only water, air, and electricity. This capability lowers logistics mass, minimizes stored consumables, and increases operational flexibility by allowing crews to respond immediately to contamination events. Hydrogen peroxide is compatible with life support systems because it decomposes into water and oxygen, avoiding harmful residues in closed-loop environments. It also supports crew health by helping control microbial growth on surfaces and within systems, while offering multiple uses such as surface cleaning, system sanitization, and water stabilization. Overall, this technology enhances mission sustainability, autonomy, and resilience for long-duration exploration missions.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
