Scientists develop new, efficient method for removing, storing carbon dioxide from the atmosphere
(MENAFN) Scientists have proposed a new method of capturing carbon dioxide (CO2) from the atmosphere and storing it in seawater as bicarbonate of soda. This approach is said to be up to three times more efficient than existing methods of capturing the warming gas. The new method could help to accelerate the deployment of carbon removal technology. While the world has struggled to limit and reduce CO2 emissions in recent decades, several companies have focused on developing technology to remove CO2 from the atmosphere. One such company is Climeworks in Switzerland, which has developed machines to filter and trap CO2 molecules from the air.
At a plant in Iceland, Climeworks injects the captured CO2 deep underground, where it is permanently turned into stone. The company has recently started selling a certified carbon removal service to large corporate clients, including Microsoft, Spotify, and Stripe. However, the cost of most direct air capture approaches is still a major issue. CO2 is relatively diluted in the atmosphere at around 400 parts per million, which means large machines that require large amounts of energy are needed to absorb and discharge the CO2.
This new approach offers a solution to this problem by using off-the-shelf resins and other chemicals. The authors of the study claim that this approach can capture CO2 from the atmosphere up to three times more efficiently than current methods. The captured CO2 is then transformed into bicarbonate of soda, which can be stored safely and cheaply in seawater. This new method is said to be far more efficient and lower in cost than existing methods. It could help to speed up the deployment of carbon removal technology and provide a cost-effective way to address the problem of CO2 emissions.
The study is significant as it offers a practical solution to the problem of direct air capture, which has been hampered by high costs. The new approach promises to be a more efficient and cost-effective way of capturing CO2 from the atmosphere, and it could help to accelerate the deployment of carbon removal technology. This could be an important step in the fight against climate change, as reducing CO2 emissions is essential for mitigating the impacts of global warming. The new method offers hope that we can find practical and affordable ways to address this critical environmental challenge.
