In order to stop the ill effects brought about by climate change, the world is realizing that it must do something to pull off the carbon dioxide out of the atmosphere. Scientists have engineers have proposed many ways to do this, but most of them would cost a lot of money and resources, and “no one wants to foot the bill”.
However, there is one method explored in the past decade that humanity may be able to use.
… [It] might now be a step closer to becoming practical, as a result of a new computer simulation study. The process would involve pumping airborne CO2 down into methane hydrates—large deposits of icy water and methane right under the seafloor, beneath water 500 to 1,000 meters deep—where the gas would be permanently stored, or sequestered. The incoming CO2 would push out the methane, which would be piped to the surface and burned to generate electricity, to power the sequestration operation or to bring in revenue to pay for it.
There are still some issues with regards to this method. However, as time passes by, this becomes more and more viable.
