is is possible to make captured carbon back into a useful solid form?

Question

For many years now I have wondered why we aren’t able to turn the air captured carbon into useful things like carbon fiber or carbon nanotube batteries. surely there must be some way of doing this through the magic of chemistry.

Answer 1

[Graphene](https://advanceseng.com/worlds-thinnest-graphene-filter-carbon-capture/) is part of the answer. Needs time to scale up.

“In a nutshell, EPFL chemical engineers successfully developed a graphene filter for carbon capture that surpasses the efficiency of commercial capture technologies, and can reduce the cost carbon capture down to $30 per ton of carbon dioxide. The research team is now working on scaling up the process by developing a pilot plant demonstrator to capture 10 kg carbon dioxide per day, in a project funded by the Swiss government and Swiss industry.”
