Hi Renaud,
Thank you for your kind words, and happy to share ! It should be fairly easy to calculate those energy costs, and even include average transport and application costs as per the paper of Nils Moosdorf (https://www.researchgate.net/publication/260561373_Carbon_Dioxide_Efficiency_of_Terrestrial_Enhanced_Weathering). It is very well possible to calculate all these types of costs fairly accurately. We did not do that here, because a) the comminution (grinding) costs are very low [see Moosdorf et al, 2014] and b) the scope of the paper needed to be (somewhat) constrained. I can tell you we have been discussing this and hopefully will include it in a future study. saludos, Francesc On Saturday, 25 March 2017 19:40:48 UTC-3, renaud.derichter wrote: > > Dear Francesc, > Great job!
