Selecting rock types for very-low-cost crushed rock heat storage …
Heat storage cost is primarily determined by building costs because (1) the very low-cost of crushed rock and (2) the nitrate salts are used for heat transfer but not heat storage. Building foundation and insulation are the costliest components because the building is a light-weight structure with no rock or salt forces on side walls.
