I suspect that if viable fusion power plants become a reality today we will be burning synthesized hydrocarbon fuel for centuries to come. There is vast hydrocarbon fuel infrastructure in place already. If it costs a few cents to synthesise oil from air because you have hyper abundant fusion energy on hand then it would be silly to throw away the infrastructure we have.
