Researchers develop a sustainable gel film to capture carbon dioxide with reduced energy cost

„Direct air capture (DAC) technologies extract CO2 directly from the atmosphere at any location, but their practicality is limited by the higher energy needs and overall costs. In particular, most solid-sorbent-based systems cannot function well in humid conditions and have high regeneration temperatures or require vacuum conditions. To overcome these challenges, we developed sustainable carbon-capture hydrogels (SCCH) as a step-change material for CO2 capture with high uptake and exceptionally low regeneration energy (Figure 1).“
