Needs massive energy input which would come from where? Also, massive amounts of toxic chemicals. Use biology to solve climate change by growing biomass (bio CCS) in the form of kelp, diatoms, and other high growth life (maybe GMO) to sink to the bottom of the ocean.

Nuclear plants can provide plenty of excess electricity as well as heat for thermal desalination.

Sounds like wishful thinking/hand-waving. Plus, the risks of and limitations of nuclear energy.

Biological processes are far more efficient at fixing carbon into biomass and using unlimited free solar energy. Bio CCS.
