Thank you for your comment!<br /><br />I am also questioning if wind or solar energy would have the ability to provide vast amounts of energy, I think a lot of research is required to provide large amounts of energy. However, I do believe that nuclear power would be more sufficient in this case.<br /><br />In regards to if CDC will ever be carbon neutral. I believe it has potential. Technology is constantly advancing, therefore, it is highly likely that more efficient methods of fossil fuel use can be managed, although this is very hard to achieve. However, I think for CDC to be truly carbon neutral it would need a renewable energy. Yes there would be some carbon costs in terms of construction and transport materials, however, I don't think it would be as much as all the absorption that could take place in the long run.<br /><br /> I hope this answers your questions!Maria Christofihttps://www.blogger.com/profile/17691421487635204262noreply@blogger.comtag:blogger.com,1999:blog-5066455796527100553.post-86375903579263489622015-12-15T12:21:45.014-08:002015-12-15T12:21:45.014-08:00Hi Loulou, Thank you for your comment! I completel...Hi Loulou, Thank you for your comment! I completely agree, the fact that they require energy is a big downturn for CDR and yes it should come secondary in regards to making our own energy mix more efficient and less carbon reliant. I believe nuclear power would be very sufficient in terms of providing these kind of geoengineering schemes (although that has its own risks)! Nonetheless, I am unsure if other renewable energy would have the ability to provide these large amounts of energy for geoengineering (at least for now!).

I really enjoyed reading this post! The ...Hi Maria! I really enjoyed reading this post! The CDC requires large amounts of electricity - which you very rightly say shouldn't be provided through burning of fossil fuels. However do you think the energy produced from wind and solar energy could realistically reach the scale to power such a process? Furthermore, renewable forms of energy come with their own carbon dioxide emissions (e.g. in construction, transport of materials etc.) so would the process of CDC, particularly through it's required electricity provision, ever really be carbon neutral? I am sceptical. What do you think?Xhttps://www.blogger.com/profile/11099031157160610657noreply@blogger.comtag:blogger.com,1999:blog-5066455796527100553.post-47271539597622144072015-12-15T03:19:39.155-08:002015-12-15T03:19:39.155-08:00Great overview of some CDR methods I had not come ...Great overview of some CDR methods I had not come across yet! You mention that one down-side of the CDR methods proposed here is that they require large amounts of electricity to work. Don't you therefore think that these methods, and therefore investment and research, should come second in line to trying to make our energy-mix more efficient and less carbon reliant ?Anonymoushttps://www.blogger.com/profile/03950072046937252288noreply@blogger.comtag:blogger.com,1999:blog-5066455796527100553.post-3213866099104299132015-12-01T16:17:57.433-08:002015-12-01T16:17:57.433-08:00Hi Caitlin thank you for your comment. I think t...Hi Caitlin thank you for your comment. I think the fact that the methods are largely industrial is what creates insecurity for people, as it is 'big' and unknown, hence not knowing its implications. I am unsure if it is negative that they are reliant on industry. To some extent I guess it is bad as there is an issue of management and who will pay for it. However, with the correct technological advancement and correct management schemes, this may change, hence decreasing their reliance on industrial processes. <br /><br />Nonetheless, I believe, ideally, the best way to reduce carbon dioxide is through the 'traditional' approach. Unfortunately, it is not working, even though they have been trying for many years. Therefore, I do believe there is a large potential in CDC. However a lot more research is essential, especially in the reduction of costs and utilising the absorbed carbon dioxide. If that were to happen, I am sure it could be a viable process. However, the unfortunate thing with all geoengineering processes, is that they have never been tested, so nobody can tell us if this process will lead to any unpredictable negative implications, that have not been thought of. Another negative consequence is what will happen if one of these processes break or fail? There isn't an undo button. <br />I hope I have answered your questions! If you disagree or have any other thoughts on the matter, by all means let me know!

I think ta...Hi Maria, really interesting blog post!<br />I think talking about the real possibility of CDR and specifically CDC methods is a progressive step that is becoming increasingly important. Do you think that the fact the methods are largely reliant on industry, such as large filters, is a negative element of the techniques? Do you think they should be completely decoupled from industry and that viable sustainable alternatives developed?<br />I think they have a potential future in mitigating climate change, however are arguable too unstable and unpredictable at this precise moment in time?<br />Looking forward to your "part 2" post! :)Anonymoushttps://www.blogger.com/profile/01957225695585655707noreply@blogger.com
