Technology Description:

Palo Alto Research Center (PARC) aims to develop a highly efficient sorbent material and MSA process for direct air capture of CO2, leveraging PARC's novel aerogel chemistry incorporating quaternary ammonium cation groups to reversibly adsorb CO2 with changes in humidity. The new material and process will substantially improve the capital and operating costs of CO2 capture through reduced materials and process costs as well as enhanced sorbent performance. The team will advance the critical sorbent materials parameters that drive MSA system performance to give a transformational combination of capacity, sorption/desorption kinetics, cycle life, and cost. The project technology will potentially enable ambient air CO2 capture at the >1 Gt CO2/yr scale at $100/tCO2.

Potential Impact:

PARC will develop a novel, high-performance sorbent for MSA incorporated into a prototype DAC module to de-risk materials integration.

Security:

The creation of new sorbent materials and processes for carbon capture will ensure the U.S. maintains a technological lead in developing and deploying advanced carbon capture technologies.

Environment:

The technology will enable Gt CO2/year DAC at <$100/tCO2 and <5% embodied emissions.

Economy:

PARC will substantially improve the capital and operating costs of CO2 capture through reduced materials and process costs and enhanced sorbent performance, significantly improving the economic viability of DAC.
