The biggest problem about Saharan solar farm is how are you going to get the power to where it needs to be?
It has been studied, partially funded, called DESERTEC, put on hold since the Arab Spring.
Basically: big DC power lines. The tech is known and exists.
I don't know if the various hydrogen production or methanation processes are advanced enough to consider these as an alternative though.
