Aha, so it's targeting "CCU". Then OK, I can maybe see there is a point initially, but not at anything near the scale we need.
Global graphite production from mining is at 1 megatonne/year, while synthetic is a few hundred kilotonnes/year. We need CCS to operate at tens of gigatonnes per year, that's four orders of magnitude beyond all the graphite the world needs.
This is the problem with anything CCU - there just aren't viable options with consumption at the gigatonne scale.
- azernik 7y agoI'd imagine extra graphite is pretty easy to store, though?
- ed312 7y agoWe could put it down in empty mine shafts... or build entire mountain tops out of it!
- semi-extrinsic 7y agoAt the gigatonne scale, nothing is easy to store. Fill the entire Hoover dam with graphite, and you've stored 6 gigatonnes. We need to store tens of gigatonnes per year for a hundred years.
