> Better keep that pressure chamber leakproof for 1000 years It seems highly unlikely that even 100 years from now we'll be net positive on CO2 release into the atmosphere. Renewables are a thing, and we're making significant progress. So once we're net negative, it'll be up to us to figure out how much CO2 to release, but it seems a certainty that long before 1000 years we will no longer need to store any of the captured carbon.
