Kurt Zenz House isn't the first scientist to suggest sequestering carbon dioxide in the ocean. But he is the first to come up with a solution that might actually work.
The key is depth. Whereas other plans to sequester carbon in the ocean were plagued by fears that the CO2 would escape, House advocates going much deeper—at least three thousand meters, or two miles below sea level into the seabed.
At that depth, House hypothesizes that the extreme water pressure and low temperature will turn the carbon into a liquid denser than the surrounding water, forming a layer that will prevent it from rising back up into the ocean.
