Carbon capture and storage (CCS) has been touted, as one of the critical technologies that could help Australia reach its climate targets, and features heavily in the federal government’s plan for net-zero emissions by 2050. CCS is generally when emissions are captured at the source and stored underground.

                Emerging overseas research shows “liquid marbles” is tiny droplets coated with some marbles under 1 millimetre in diameter and nanoparticles preventing the liquid within from leaking out, they can behave like flexible making them appealing for applications such as gas capture. could possibly address current challenges in materials used to capture carbon. And our modelling research, published yesterday, brings us a big step closer to making this futuristic technology a reality.

               In the context of CO₂ capture, their ability to selectively interact with gases, liquids and solids is most crucial. A key advantage of using liquid marbles is their size and shape, can directly be installed in large reactors. Gas from the reactor hits the marbles, where it clings to the nanoparticle outer shell in a process called adsorption. The gas then reacts with the liquid within, separating the CO₂ and capturing it inside the marble. Later, we can take out this CO₂ and store it underground, and then recycle the liquid for future processing. This process can be a more time and cost-efficient way of capturing CO₂.
