Marc, Interesting read, thanks for the background. In addition to the approaches of entrepeneuring physicists, let's not forget that nature is already way ahead of us in consuming the majority of the CO2 we emit, and doing this for free (well, there are environmental costs like ocean acidification). In gross, something like 700 GT of CO2 are naturally pulled out of the air each year by ocean and land processes. Due to leakiness a little less that this quantity is re-emitted. I'm therefore puzzled why one needs to reinvent air capture from the ground up, when it would seem that some gentle nudging of natural CO2 uptake and/or release processes might be easier and more cost effective. In any case, I think the three start-up examples you cover have a long way to go before they can compete with existing CDR both in volume and price. Building effective markets and business models for such approaches might to be another matter, but perhaps we can borrow from (the amazing) marketing skills of the physicists here. -Greg ________________________________________ From: [email protected] [[email protected]] On Behalf Of Marc Gunther [[email protected]] Sent: Friday, October 07, 2011 10:15 AM To: [email protected] Subject: [geo] my Fortune story on carbon dioxide removal
The business of cooling the planet<http://tech.fortune.cnn.com/2011/10/07/the-business-of-cooling-the-planet/>, my story about carbon capture, has just been published in Fortune. I'd appreciate feedback (ideally offline) because I plan to expand the story into an ebook in the next month or two. Marc Gunther Let's all be smarter about email.
