Gates backs Icelandic startup that turns carbon dioxide into stone

Some of the carbon capture tech coming down the pipe awes me — esp. what we are doing with construction materials, since cement is a notorious carbon dioxide producer. Last year a team at UCLA unveiled a similar system that captures waste C02 to create concrete, and Carbon Cure unveiled another form of green concrete earlier last year. It humbles me to reflect on what we monkeys can do when faced with a problem, and how much we could do without our propensity for self-inflicted wounds.

It actually does make sense to do this on a massive scale because it doesn’t really matter where you take the carbon dioxide out of the atmosphere: the entire atmosphere will contain a similar amount of carbon dioxide no matter where you take it from, and if you suck it out of one area, carbon dioxide from the surrounding area will just displace into that area. So hypothetically, carbon dioxide would slowly “flow” towards areas where it is taken out of the atmosphere: the atmosphere does this work for us. So you can just run ultra massive carbon dioxide sequestration machines in Iceland or any other country with unique geothermal resources, and essentially just use the Earth to power its own sequestration of carbon dioxide. ​ Also this would be a decent boon for countries with geothermal, since they could essentially just charge countries from around the world a subscription fee to this global service that they can uniquely provide much of because of their unique economics. I mean, not that they need it: Nordic Countries are essentially the best countries in the world in terms of creating stable societies, this is just more icing on their cakes.

The headline does not reflect what the article says the process does. The article says the process involves pushing gas (air, CO2) into spaces between rocks underground.
