On https://www.youtube.com/watch?v=NngCHTImH1g https://www.youtube.com/watch?v=NngCHTImH1g he says the goal is $100/tonne carbon capture and $1/kg H2, which puts those inputs well under the $10/kcf leaving some margin for the cost of the sabatier. Both processes are directly proportional to the cost of electricity and heat so assuming the thesis of decreasing solar costs holds true, it's a question of when not if.
