Do you have a reference for this? Pumping CO2 into the depths of the ocean seems energy- and infrastructure-intensive, and I'm curious how you'd keep it there.

Do you have a reference for this? Pumping CO2 into the depths of the ocean seems energy- and infrastructure-intensive, and I'm curious how you'd keep it there. If work has been done on modeling and/or measuring feasibility I'd be interested to read it.
- ncmncm 5y agoThere was a paper on HN just a last week. Park a floating wind turbine on a buoy out in deep water, to be paid for with carbon credits. The amount of CO2 sent down is exactly measurable from pH and volume. The wind turbine doesn't need an expensive generator with 6 tons of rare-earth magnets, it can couple straight to the pump mechanically or hydraulically. https://news.ycombinator.com/item?id=29912896 https://news.ycombinator.com/item?id=29912896 Except at certain well-known places, very little mixing happens naturally. Of course we need thousands or tens of thousands of them, not just one, but there has to be a first one.
