RE:RE:RE:CCSWhat I think is novel here is that they are storing it in brine resevoirs, as what I believe is a liquid. They are not storing CO2, as it is pre-combustion. They are stripping the carbon off so there is nothing to form CO2 when it burns. If it is a liquid, should be similar is costs to pumping disposal water ($2-3/ton). The importance of liquid phase is that does a couple things, first is increases the density of the carbon allowing for low pressure injection and second it reduces the likelyhood of leakage coming up due to fracturing.
There is no lack of empty liquid storage below ground in Canada. You have brine located all over SW Ontario, and the WCSB.
