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.

A short ELI5 answer is that we are capable of doing it but it takes a lot of energy so it is not worth it.
