Of further merit is the favourable electrical and thermal conductivities of the adsorbent, which are sufficiently high such that Joule heating desorption can be carried out directly, offering the opportunity to employ renewable energy sources to drive the desorption. This significantly improves the techno-economic argument and credibility for this as a viable DAC technology. The relatively low costs of the constituent material and electrolyte also point to the potential readiness for commercialization. Beyond its use in DAC, the authors’ demonstration of readily tuneable charged-sorbent materials, where the electrolyte and electrode can be rationally selected and designed, should lead to a family of new materials with applications in various energy-efficient gas separation technologies and energy conversion processes.
