The thermal 'inertia' of concentrated solar power may be cost competitive with PV solar and batteries.
You can use the mass of the concentrator target as a thermal battery effectively, as the conversation of sunlight to electrical energy is not instantaneous like solar PV.
Almost anything you can do with concentrated PV, I can do better with photovoltaic and a resistor immersed in the same thermal storage medium. It is wildly more versatile in the face of clouds and piping + insulation costs.
