California's Carbon Deadline Is Approaching. Meeting It Will Take Hundreds of Miles of Pipelines.

Plans call for millions of tons of carbon dioxide to be piped across the state to the Central Valley and Sacramento delta for burial.

    Why is the Delta considered the best sequestration site in the state? I thought you wanted to pump into certain types of bedrock to mineralize the CO2 to prevent it from leaking. The valley has basically no bedrock under it for thousands of feet, so this plan makes little sense to me. What keeps it from leaking back out?

        Thanks but I’m not going to take a company trying to get rich off of this technology at their word. The claim that it will stay down there when there’s no solid barrier seems dubious, unless there’s some unique chemical process at play here.

          unless there’s some unique chemical process at play here.

          CO2(aq) + H2O(l) ⇌ H+(aq) + HCO3–(aq)

          That reaction is taught to High Schoolers and is hardly unique. It’s also quite literally the #2 thing explained in the link that @silence7@slrpnk.net gave you.

          Are you a science denier?

            I’m familiar with this chemistry, but I wonder if you are? Carbon dioxide’s various reactions with water are normally in equilibrium with the atmosphere, meaning if you increase the carbon in the water, it will off-gas any extra carbon until it returns to equilibrium. Hence the need for some unique chemistry (or other process) to keep the carbon in place for an extended period.

            Am I a science denier? Would I be a science denier if I questioned Exxon’s public statements about climate change in the 90s? What a silly question.

            PS: there’s no chemistry in this link that I can find so I have no idea where you are getting that idea.
