Membrane Separation Technology in Direct Air Capture [PDF]

Membranes
Direct air capture (DAC) is an emerging negative CO2 emission technology that aims to introduce a feasible method for CO2 capture from the atmosphere. Unlike carbon capture from point sources, which deals with flue gas at high CO2 concentrations, carbon ...

Intrinsic direct air capture. [PDF]

Chem Sci
How can you tell if a sorbent material will be good for any gas separation process – without detailed simulations of the full process? We present new metrics to evaluate solid sorbent materials based on intrinsic properties of the sorbent material.

Distributed direct air capture by carbon nanofiber air filters. [PDF]

Sci Adv
The rising atmospheric CO2 concentration is one of the biggest challenges the human civilization faces. Direct air capture (DAC) that directly removes CO2 from the atmosphere provides great potential in carbon neutralization and even reverses the CO2 concentration in the long run.

Enzyme assisted direct air capture of carbon dioxide

Carbon Capture Science & Technology
Direct air capture (DAC) has been widely advocated as a key tool in the strive towards zero emissions. Here we present the first systematic data on enzyme assisted DAC and show that CO2 absorption rate tripled upon addition of carbonic anhydrase (CA) at ...
