Graphene Layer has a novel approach to direct air capture (DAC) that has been in the developing process of using graphene membranes. DAC is a technology for removing carbon dioxide (CO2) from the atmosphere and capturing it for storage or utilization. Current DAC technologies consider only sorbent-based systems. Recent speculation has also suggested that gas separation membranes might provide the same separation since they are smaller in footprint and easier to operate and set up; however, their application in the field remains speculative. The graphene membranes offer a highly efficient and selective means of separating CO2 from other atmospheric gases, enabling the effective removal of CO2 from the atmosphere. This breakthrough technology has the potential to significantly enhance the effectiveness of DAC systems, making them more efficient, cost-effective, and making them more viable for mitigating the impacts of climate change. The graphene membranes are robust, scalable, and cost-competitive, which makes them a promising solution for mitigating the impacts of climate change and achieving a more sustainable future. This research opens up new avenues for advancing DAC technology and mitigating the effects of atmospheric CO2.
