Mark et al., I grew up along the Texas coast and can tell you that the geological storage capacity for CO2 is...zero. Most, if not all, of the ground water is highly contaminated due to past drilling (there is no closed-loop system) and the brine. You will not see crop irrigation along the South Texas Gulf Coastal Region simply for the fact that the use of the *highly contaminated ground water* would flat out kill the crops. Humans would eventually die if they drank it! Also, there is a heavy sulfur contamination which may effect the chemistry of this proposal. As to the idea that there is some form of closed loop system in that area, please consider that that particular area has probably been the most intensely drilled area on the planet for close to 100 years. Even operating miles down, the probability of finding a geological structure that is not the geological version of Swiss Cheese is small. The statement of *"the storage procedure itself would produce a vast amount of methane for fuel," *is taking for granted that all the old wells can be permently plugged (for geological time) (or even found!) and that the cap formations have not fractured due to the lack of the origional pressure holding them up. When it comes to the Texas Gulf Coast and CO2 geological storage, we may best keep in mind that that area is home turf for much of the global FF industry. I'm sure that they are happy to sell the idea that all is warm and fuzzy when it comes to dealing with climate change. Best Michael
