TL/DR - they’re using mini solar tower collectors to concentrate and collect sunlight to charge PV panels. This produces a lot of excess heat (enough to melt steel) - the heat is pumped away via water into an underground vault where the heat is stored until the evening where the heat is converted back into electricity using conventional off-the-shelf materials and hardware.
