I posted about this here on June 3, and received the comment from Olaf Schulling that "The hotter the fluid, the less dissolution of CO2." This would indicate that hot brines are not appropriate reservoirs for storing CO2. Perhaps they are a case of an industry seeking subsidies by demonstrating side-benefits? I haven't seen any CCS technology that looks inherently efficient, and sincerely hope there won't be one. CO2 is not a poison and to pressurize and pump it underground is a fundamentally stupid idea.
The other two legs of the stool which Bryant describes, geothermal low-temperature process heat and methane extraction from brine, at least sound preferable to electric generation and fracking respectively.
