It's also an issue of scales. The volumes of CO2 we need to store are absolutely staggering, as in tens or even hundreds of Hoover dams every year.

- worldsayshi 10y agoThat's if we don't convert into other materials?
- semi-extrinsic 10y agoThat's for supercritical CO2 as it would be transported in pipelines, at a density about 0.6 times that of water. IIRC we need to store many tens of Gigatonnes of CO2 per year. If you make it into plastic, you can divide by 5 (roughly). Total world plastic production is around 0.3 Gigatonnes
- worldsayshi 10y agoYeah, barely 10 Gigaton per year if you sum it all up [1]. But it's probably a fraction of that that is eligible for capture. 1 - https://www.co2.earth/global-co2-emissions https://www.co2.earth/global-co2-emissions
