Obama to focus on Clean Energy

In the Atlantic Magazine referred to in a Coal Post, one sequestration safety aspect was brought up. What happens if a big leak were to develop due to an earthquake or other mechanism. We know from the Lake Nyos CO2 eruption that killed 1700 people, that the danger is real.

 

well, if you put the CO in the right place it will react to form calcite, which takes it out of the atmosphere and would solve that particular problem. Again, I don't know the kinetics of the reaction and lets face it, we'd be shoving a massive amount of CO2 into the sub-surface and not everywhere has favourable geology for such things. Oil and gas fields do seem like a really good candidate for the places where they're available.
