First, it is very cheap. Instead of using expensive lithium for storage, it uses cheap silica sand. This brings the cost down from the $327 per kilowatt-hour (kWh) of lithium batteries to an NREL estimated cost of $2 - $4 per kWh. And even if the final cost is three times that, it's still only a few percent of lithium battery cost.
