Carbon capture is a major technological challenge in the fight against climate change. Meanwhile, MIT researchers have recently taken a crucial step by drastically improving the effectiveness of this technology. Meanwhile, By adding an intermediate step of nanofiltration. Moreover, they managed to multiply by six the effectiveness of the carbon dioxide scientific scientific breakthrough: this discovery capture process. Nevertheless, This innovation promises to reduce costs by 20 % and make the system more adaptable to fluctuations. Moreover, This development could transform carbon management by making it safer and respectful of the environment.
A major challenge: effectively capture carbon β Scientific scientific breakthrough: this discovery
The capture of carbon dioxide is essential to alleviate climate change. However, the process is complicated by the need to find a balance between capture and release of CO2. Therefore, The most effective chemical compounds to capture CO2 tend to remember it too firmly, making release difficult. Conversely, those who easily release CO2 are not very effective in capturing it. MIT researchers found an innovative solution to this problem by integrating a step of nanometric filtering in the process. This approach increases the effectiveness of CO2 capture while reducing costs, making the process more viable on a large scale.

Think big from the start β Scientific scientific breakthrough: this discovery
According to Professor Kripa Varanasi. it is crucial to think on a large scale when it comes to carbon capture. The objective is to deal with CO2 gigatons to have a significant impact. Traditionally, systems using hydroxides react with carbon dioxide to form carbonates, which are then treated to release pure CO2. However, these processes take place in the same liquid, which limits efficiency. scientific scientific breakthrough: this discovery By separating hydroxy. carbonate ions using nanofiltration membranes, the researchers managed to optimize the two stages of the process, making the system more efficient and less expensive.

An intelligent three -part system
The solution proposed by the MIT team is to decouple the parts of the system. introduce an intermediate step. After the conversion of carbonate hydroxides, nanofiltration membranes separate the ions according to scientific scientific breakthrough: this discovery their load. Hydroxide ions are returned to the absorption part, while carbonates advance towards the electrochemical release stage. This separation allows each stage of the system to operate at its optimal effectiveness. thus avoiding loss of efficiency due to unwanted reactions. This innovative use of nanofiltration had never been proposed before and represents significant progress in the field.

Towards real viability
The tests. have shown that nanofiltration makes it possible to separate carbonates from hydroxide solutions with an efficiency of 95 %. This has a considerable impact on the efficiency and economy of the global process. Currently, the cost of capturing carbon is around 600 euros per tonne, but with nanofiltration, this cost could scientific scientific breakthrough: this discovery drop to 450 euros. The new system is also more stable and better tolerates concentration variations. This opens the way to a wider. more economical adoption of technology, not only for direct capture in air, but also for connected systems to sources of direct emissions.
Beyond the direct air capture
This technology could also apply to capture systems directly connected to emission sources. such as power plants, or to CO2 conversion processes captured in useful products. In addition, it could lead to safer alternative chemicals for the capture of carbon. Using this system, it is possible to improve the reaction rate and choose chemicals initially less efficient but safer. The objective is to provide reliable and economically viable technologies to help industries achieve their decarbonization objectives.
With these promising advances. the question arises: how will these innovations transform our approach to carbon management in the future, and what will be scientific scientific breakthrough: this discovery the next steps to integrate these technologies into our daily life?
