The sun provides energy for plants to take CO2 and turn it into O2, (transpiration). Algae are the major plants that do this, on earth, and I understand there is a belief that the oceans are losing a lot of their ability to sequester the CO2 on the earth. The increase ocean temps are hurting a major species of algae. At least this is what some scientist or saying.
Patrick,
You can sequester CO2 but to only sequester carbon requires the separation of the carbon and oxygen. This requires as much energy as that was released when the carbon was oxydized. In other words, when you burn hydrocarbons and then try to separate the oxygen from the Carbon, you have now spent as much energy in the separation as you consumed in the first place and hence no gain.

At last evening's after-SPOC Advanced Training Session the subject came up about carbon sequestration.
It occurred to me that most (if not all) of the talk I've heard on the subject has been about sequestering CO2 (mostly oxygen) and not just the carbon.
Have I got that right?
If so, why hide away the oxygen with the carbon rather than just to carbon?
Any ideas?
Thanks,
patrick
