MIT has found economically viable means to implement carbon capture from the oceans.

Acidification of the oceans is a huge and ongoing problem. To reverse this process means to bring about a stream of carbon capture that may very well return function to ocean waters and Earth's troposphere. CO2 will continue to enter the ocean environment, but, it is a better storage facility than the gaseous layers of Earth. If this process can be commercially viable it should be pursued, especially in areas of the ocean where acidification is already a problem, ie; Northwest USA waters. It will return function to the fisheries.

As the CO2 is removed from the oceans in carbon capture to make diamonds or other solid carbon products that WILL NEVER ENTER THE ATMOSPHERE AGAIN, more CO2 from the atmosphere will enter the ocean and the cycle will continue. The acidification will be reduced, but, will need to be maintained in a commercially viable process.

This discovery is from the scientists at MIT.

Asymmetric chloride-mediated electrochemical process for CO2 removal 

from oceanwater

Current studies on CO2 removal (click here) from oceanwater have used bipolar membrane electrodialysis (BPMED), although the high cost of bipolar membranes might impede the commercialization of the process, and some of these architectures even present risks of toxic redox-couples leaking into the oceanwater. We propose a new approach based solely on electrochemical modulation of the pH to initially release the CO2 and then to alkalize the treated water before it is returned to the ocean. This approach (i) does not require expensive membranes or addition of chemicals, (ii) is easy to deploy, (iii) does not lead to formation of byproducts or secondary streams, and (iv) requires a lower energy input (122 kJ mol−1) than do other approaches, to the best of our knowledge. In addition, a preliminary technoeconomic analysis which suggests that this ocean capture system can be economically feasible.
