major hurdles, including high costs, remain before this technology can be widely deployed and play a key role in tackling climate change.
Major. Major, Major Challenges. CCS, (lets put the capture prt to one side and focus on Storage) is well proven as a gas field injection method to increase yield: Fugitive gas from fracking is a huge problem. Persisting injection, down into olivine or other rocks (basically, encouraging the CO2 to convert to carbonate solid) or into pressure depth as clathrate (I know methane clathrate is a thing, I assume CO2 does similar things but I could be wrong).. this is still really not at-scale simple.
A major Australian CCS project has continually reported failure to meet its goals, such that its had to pay massive fines to the WA government because of un-met Carbon offset benefit... which I bet partly helped 'justify' the investment on the gas field.
Given that the CO2 could easily be used to help pump more oil from underground I've never suspected actual storage is a problem.
(Oil that isn't burnt or thrown away is still _crazy_ useful imo)
I just doubt the seriousness of industry to invest in this in a significant and meaningful way...
