| Project Detail |
Captura will demonstrate efficient CO2 stripping from oceanwater using low-cost thin film composite hollow fiber membranes. The team will use ultra-low-cost hollow fiber membranes, traditionally used in water filtration applications, as a structural support, and modify their outer layers with highly CO2 permeable polydimethylsiloxane layers to selectively strip CO2 from oceanwater. Captura will also employ a computational model-assisted design and rapidly prototype new gas liquid contactor designs that use counterflow and cross-flow design for efficient CO2 stripping from oceanwater. The team estimates a >10x cost reduction in the capital expenditure for the CO2 stripping unit. |
