Forest for the Trees (Part 1 of 3)

In Part 1, I introduced the carbon capture technique being employed in Iceland.  In this part I’ll dive a bit more into how this technology works.  In Part 3, I’ll zoom back out to illustrate the variety of technologies (spurring many projects) that all aim at removing carbon from the atmosphere.

I was going to write a long, detailed post but found this wonderfully expressed video with outstanding imagery of the project and an explanation of how it works here:

AnthropoScene III : Hellishei∂i; or, the Post-Modern Prometheus from Adam Sébire on Vimeo.

This diagram also provides more for those with the technical inclination.


The project management question here (other than the scope, schedule, budget of the project) is this – for your consideration: are there any secondary risks to this process?  One article in Science magazine says:

Bigger field tests are needed, says geologist Peter Kelemen of Columbia University, to confirm that such a high fraction of the injected carbon was mineralized. (Columbia is a CarbFix partner, but Kelemen is not on the project.) Scaled-up demonstrations could also make sure that the speed of the reaction won’t turn into a drawback, Stanford’s Benson says. If carbonation generates minerals that quickly plug the pores in the basalt, she worries, they could trap CO2 near the injection site instead of letting it spread through the rock.

There is research in this area – some examples here and here.

Ironically, even in the area of sustainability projects, long-term thinking, and secondary risk considerations are critical.

I'm not seeing the irony. One should be especially cognizant of long-term effects and secondary risks if one's project seeks sustainability.

Thanks @Glenn.
Perhaps irony is a poor choice of words, just noting that it’s interesting that even on sustainability-oriented projects we must also think about long-term effects. So - I fully agree.

Thank you for sharing. I guess it defeats the purpose if sustainability projects are not considering long-term impact being sustainable as well!

Interesting Post. Thanks for sharing

Kind of an eerie video. Really says something about where we are. Nonetheless, pretty amazing.

I was waiting for the zombies to jump in during the video.

Very interesting, some good reading in the linked documents
