(33,982 posts)posters did, and you are correct, it's not a greenhouse problem once it's in the water. I consider it a valid, or worthwhile 'cycle' to run (much preferable to fresh drilling for untapped hydrocarbons) because I consider the CO2 dissolved into the oceans to still be 'in flight' as a human impact on our environment.
I disagree with the timeline you've specified, however, or we're in deep shit, because the CO2 concentration in the oceans has risen considerably since the start of the industrial revolution. And that's only 300 some years. If there's hundreds of years of lag, our oceans are dead already, they just don't know it yet. (Equilibrium takes somewhere around a year, actually)

Battery technology is advancing at a rate that, honestly, if I were an investor, I wouldn't throw any money at this. 10 years to bring it to market? Tesla is going to slam out a commuter version of the 'S' next year. For many mobile applications, this is already dead tech.
It will be useful pretty much to the military only.
