Idea – Man Made Molten Rock (Lava) As An Energy Storage?

Because volcanoes are a terrifying display of energy. Could this inspire a new energy storage. In comparison with pumped hydro. Could we develop man made molten rock or lava as a way of storing energy? Not tapping into a natural source but actually making our own molten rock.

Because the material is so very very cheap (rock) compared to Litium Ion batteries. I think this is definitely worth the research. Also using lava should mean no metal shortages.
