I wonder why they didn't mention Carbfix [1], the Icelandic project that pulls CO2 from the air and flushes it underground. That's been going on for a few years now.
edit: According to Carbfix's "Current Projects" [2] section, it looks like they actually collaborated with Climeworks on this Project Orca.

- hanniabu 5y agoHow is it kept underground? Would an earthquake release a bunch of it?
- Ma8ee 5y agoThey turn it into rock, so no.
- Johnny555 5y agoFrom TFA: And there it will rest. Underground. Forever, presumably. The carbon dioxide captured from the Icelandic air will react with basalt rocks and begin a process of mineralization that takes several years, but it will never function as a heat-trapping atmospheric gas again.
- zug_zug 5y agoGreat question - Carbfix seems to be saying they already achieve $30/ton, which is already more than 10x better 5-6 hundred per ton the article cited as a goal. I'm confused.
- DoingIsLearning 5y agoIt seems to depend on basaltic bedrock for the reactions they mention. So you are probably limited in scaling this to other non volcanic regions in the world. Still maybe other countries could pay iceland to be a world air scrubber? Not sure.
