Every scenario for fusion power requires extremely expensive processes to extract heat, and then using it to drive steam turbines. But operating steam turbines, all by itself, costs more than renewables.

These extremely expensive processes would cost way more than is needed for fission. But fission is already not competitive. (See above.) So there is no future for fusion driving heat engines.

There just might possibly be a future in aneutronic fusion, fusing deuterium with 3He and extracting the energy directly electromagnetically. But all these announcements are not about that.
