Sustaera Demonstrates Sorbent Stability

Hey everyone! We’ve been heads down at Sustaera over the past several months, focusing on our technology development and making significant progress that we’re thrilled to share with you! Last year we re-focused our efforts on our technology development by moving into a new office/lab space at First Flight Venture Center in RTP, North Carolina where we built new and improved lab testing capabilities that directly mimic the process conditions of our pilot and commercial units and updated our internal development milestones.

We first built out a fast-cycling sorption array to test multiple samples simultaneously under our commercially relevant conditions to assess sorbent performance and stability. The unit uses 400ppmv CO2 in air (21% O2 in N2) for adsorption gas and can mimic our process cycle heating and cooling rates as well as cycle time to achieve on average 30 cycles in a day. This fast cycling of multiple core samples operating 24/7 for over 6 months yields valuable data to quickly sort and filter which materials and process parameters are optimal which we can then down select to assess for stability in a period of weeks instead of months or years.

In November 2023 we achieved a critical first milestone, demonstrating our novel sorbent can by cycled in direct air capture conditions on the scale of years before replacement! This validation of our sorbent performance and stability has enabled further progress on our development pathway towards commercial Direct Air Capture of CO2.
