Remember CO2 capture from a flue gas stream does not reduce our existing atmospheric CO2 concentrations which are higher than they've been in over 3 million years (10X longer than we've been a modern species and 300X longer than we've had modern civilization). We MUST achieve atmospheric reductions soon (per the IPCC) which means some kind of rapidly scalable DAC and/or CDR. Solid Carbon is a key pathway there - but also remember the density of the solid carbon matters if you want to sequester carbon faster by handling the same amount of stuff. This research produces "flake" carbon (which appears to be less dense. From a rapid sequestration standpoint, the optimal form of solid carbon is denser. Probably graphite produced from zero fossil energy. The challenge is low-cost production and identifying new/expanded use-cases for graphite as a sequestration medium (new markets and new materials need developed here). This research is important and barking up the right tree but there's a lot of room for optimization if rapidly scalable sequestration is the objective.
