I have read with surprise (and pleasure) about a new process to eliminate the carbon dioxide that exists in nature, and in this case it is extracted from the water and not from the air, and that is one of its greatest advantages since water has a greater amount of carbon in it.
The ocean absorbs 30% of our carbon emissions, and since water is 800 times denser than air, the concentration of carbon dioxide is about 120 times higher in the ocean than in the atmosphere. And that is why the company Captura has focused its objective on extracting carbon dioxide from seawater.
Captura is a company that has developed this new carbon capture technology designed to be more efficient and cost effective than traditional methods. The company's technology uses electrodialysis to remove carbon dioxide from seawater.
Electrodialysis is a process that uses an electric field to separate ions in a solution. In the case of Capture technology, the electric field is used to separate carbon dioxide ions from water molecules.
The first step in the process is to pump seawater into the Captura system at the surface of the water. There, seawater passes through a series of membranes. The membranes are made of a material that allows the passage of water molecules, but not carbon dioxide.
As seawater passes through the membranes, the carbon dioxide molecules are separated from the water molecules. Next, the carbon dioxide molecules are collected and stored.
The remaining water molecules are returned to the ocean. And the water molecules that are not damaged by the process can be used for other purposes, such as drinking water or irrigation.
Capture technology has several advantages over traditional carbon capture methods. First, it is more efficient. Traditional carbon capture methods often require large amounts of energy to work. Capture technology consumes less, and can be operated using renewable energy sources, such as solar and wind power.
Second, Capture technology is more cost effective. Traditional carbon capture methods are expensive to install and operate. Capture technology, on the other hand, is designed to be more affordable.
The company's first estimates are that removing a ton of coal costs less than $100, which is a fifth of that of other extraction systems. And over time they will all lower their prices.
Third, the Capture technology is more scalable as it does not require rare or special materials. Traditional carbon capture methods have a limited ability to capture large amounts of carbon dioxide. Capture technology, on the other hand, can be scaled up to capture large amounts of carbon dioxide.
The company is currently working on developing a commercial-scale version of its technology, and because the system uses standard materials, the size of facilities can grow a lot in a very short time, and the company is aiming to get the amount of one gigaton of carbon in a short time
If all this comes to pass, Captura's technology has the potential to make a significant contribution to the fight against climate change. If successful, this technology could help reduce our pollution and help mitigate the effects of climate change.
Although the expectations are very positive, we must be aware that Capture technology is still in its early stages of development, and it still has a long way to go. They have yet to perform the first operational installation, and measure its results.
Hopefully their expectations will be met and we will soon have a viable alternative to remove carbon from our environment. But without forgetting that the best contribution is not to pollute.
