The electric-vacuum swing adsorption method was taken into consideration for effective solid sorbent regeneration in DAC conditions. A novel electrified fiber sorbent that was suitable for use with the swing process and capable of Joule heating was created by dip coating process of metal on surface of the fiber. The metal with exceptional conductivity such as silver (Ag) was used to maximize the Joule heating effect while requiring less energy. The issue with the supply of regeneration energy for DAC will finally be resolved thanks to the electrified fiber sorbent’s low-power regeneration drive, which raises the prospect of utilizing renewable energy sources like solar or wind power. In this study, to reduce the cost of the DAC process, the various fiber sorbents with a novel structure has been developed and the resulting high-performance fiber sorbents will introduce a new paradigm in the field of DAC technology.
