The Palo Alto Research Center Inc. (PARC), in collaboration with Lawrence Livermore National Laboratory (LLNL), is developing a novel solid sorbent for direct air capture (DAC) of carbon dioxide (CO2). The innovative sorbent, Tunable Rapid-uptake AminoPolymer Aerogel Sorbent (TRAPS) builds on PARC’s proprietary polymer aerogel synthesis platform, which will be adapted to produce a polyamine aerogel with a combination of high CO2 capacity, rapid uptake kinetics, resistance to degradation, and low cost. During the project, PARC is developing the novel TRAPS sorbent and LLNL is testing the performance of the sorbent under DAC-relevant conditions in a lab-scale fixed-bed reactor. TRAPS will yield substantial improvements to process cost, energy consumption, and sorbent lifetime, drastically improving the economic viability of DAC.
