0 theoretical hope for fusion energy to ever provide electricity under 30c/kwh. These are hot plasma experiments, which could be used to produce mass HHO from water vapour at just 2200C-3000C, even if endothermic. Can get energy from concentrated solar mirrors or just PV solar if plasma is used. Cooling magnets is a huge energy drain. HHO provide the highest turbine energy gain, though a net gain pathway is just slightly more in reach than fusion.
