Solid-Sorbent Direct Air Capture
Cyclic adsorption of ultradilute atmospheric CO2 on engineered solid sorbents, with contactor chemistry and bed geometry design, enables repeatable CO2 removal at steadily lower energy and operating cost per tonne.
Developed mainly in: Australia, Hong Kong SAR China and IcelandImpacting: North America, Europe, Rest of Asia and Australia
Researchers from Monash University and CSIRO applied topology optimisation to the macro-geometry of a swing-adsorption CO2 capture bed using an experimentally calibrated numerical model. The resulting blunted-cone adsorbent structure is projected to remove atmospheric CO2 at $49–116 per tonne, versus $75–140 per tonne for the conventional monolith baseline.
