Completed TRL 4 (started at 3, targeting 4)
State of the art CO2 removal systems utilize packed beds filled with pelletized sorbent material. By contrast, the proposed technology uses zeolite-coated metal sheets. This form factor allows rapid thermal cycling, and thus, smaller beds. This project will design, build, and test a subscale adsorption bed of this type based on proof-of-concept demonstrated in ES62 in FY21.
This technology constitutes a revolutionary change in CO2 removal compared with the state of the art. Rapid cycling will reduce mass, volume, and energy consumption compared with packed sorbent beds.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 4) — 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.
