There is removal and then there is burial. The latter is a scam. If buried in a liquid state, it will geologically remerge into the air. Proper removal requires a chemical reaction.
- lukan 2y agoIf it is sealed in a way, that it is contained for at least some centuries, I think it is valid. But chemically binding is of course the cleaner solution.
- dymk 2y agoRe: burial: wood vaults might be feasible. You dig a hole, and bury wood in an anaerobic environment. We're pretty good at digging landfills (or use an existing strip mined location) which is basically all this is. Then you grow more trees on top of the landfill, rinse and repeat. It remains to be seen if this can actually be scaled up. https://cbmjournal.biomedcentral.com/articles/10.1186/s13021-022-00202-0 https://cbmjournal.biomedcentral.com/articles/10.1186/s13021...

If you push CO2 into natural gas reservoirs, and you plug the pipe, it will not come out. For millions of years. The only way for it to come out is for someone to actively drill and try to take it out.
- OutOfHere 2y ago> If you don't actively drill for it, it's not coming out. Please, we know that's a lie because there are thousands of unplugged drill site holes when it comes to natural gas. This is what methane flaring is about. They're constantly burning or otherwise leaking methane into the air. This is the best that human drilling has to offer, and it's piss poor. We can expect no better in terms of quality or depth for CO2 storage.
- Retric 2y ago> there are thousands of unplugged drill site holes Nobody is seriously suggesting to pump CO2 underground and then not plug up all the holes connected to that gas. Unplugged holes thousands of miles away obviously remain irrelevant. PS: Flaring is there when active extraction and processing going on. A tank on the surface getting several degrees hotter in the day is going to build up pressure, while even 20 feet underground the temperatures is constant year round and even across geologic timescales. Similarly, if you’re extracting oil then you might not care about small packets of gas reaching the surface beyond the safety hazard, thus flaring.
- OutOfHere 2y agoFossil fuel companies just cannot be trusted to seal it well. They have continuously misled the public. They will collect their contracted paycheck, then the leaks will begin. Also, when there is the slightest earthquake, the reservoir could erupt, even killing everyone in the area due to a flood of CO2.
- credit_guy 2y agoThat's why we have the EPA.
- OutOfHere 2y agoThe EPA is heavily subject to the whims of the President, lobbyists, and corrupt Supreme Court judges. The EPA is not an independent agency even if they're supposed to be. Moreover, the EPA have already failed to protect the people.
