When discussing what big, ocean-based carbon capture or storage could look like in 10 years, Matthew Eisaman likes to point out that atmospheric carbon capture will prove difficult unless it’s complemented by an ocean-based effort.
People understand the need for carbon capture – that is, the practice of capturing and storing greenhouse gases that would otherwise escape into the atmosphere. They also get the need for negative emissions technologies – processes that result in removing CO2 that has already been released into the atmosphere. There is too much CO2 in the atmosphere and we need to
