CO2 to X summary of approaches and research
Ian Page -2023.12.27 Some recent papers indicate that a lot of research is trying to navigate a rather complex space, essentially to come up with answers to the critical issue of how civilization reduces the concentration of CO2 in the air from 400+ppm to 300 to avoid the worst effects of climate disaster. The diagram indicates the major components which I will discuss, but the key overall measures are: %C How much of the expensively captured CO2 is converted to either permanently sequestered carbon which reduces the concentration of CO2, or something that replaces oil and gas extraction which reduces the annual addition of CO2 to the environment. Losses of C along the way may appear to be small but will tend to end up as CO2 again, or large quantities of some material that must be disposed of. e How large an increase in generated electricity worldwide is needed to drive the systems. I have recently pointed out from a paper that this could involve m...
