3D Photocatalytic Air Processor for Dramatic Reduction of Life Support Mass & Complexity

Completed TRL 1 (started at 1, targeting 1)

Description

The combination of novel photoelectrochemistry and 3-dimensional design allows tremendous mass saving, hardware complexity reduction, increases in deployment flexibility and removal efficiency. The high tortousity photocatalystic air processor design will achieve at least two orders of magnitude mass and power saving respectively, and enable feasibility of compact processors for spacecraft. The proposed work will demonstrate these drastic reduction in reactor mass, volume and power consumption in comparison to current technology with delivery of high-tortuosity device components allowed by 3D printing (potentially in space) at the end of the proposed work.

Benefits

This technology has the potential to dramatically reduce the cost and risk of CO2 management systems in future extended missions. The High Tortuosity PhotoElectroChemical (HTPEC) system operates in much the same way a tree would function, namely directly contacting the cabin air with a photocatalyst in the presence of light and water (as humidity) to immediately conduct the process of CO2 reduction to O2 and useful, tunable carbon products. This eliminates many of the inefficiencies associated with current ISS CO2 management systems.

How to get involved

This is early/mid-stage (TRL 1) — 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.
