The cost is dominated by the graphite insulation which prevents heat loss from the system. As the scale of the system increases, the CPE decreases because the volume to surface area ratio of the system is larger which reduces the insulation requirements. For the full-scale 100 MW, 1 GWh system the CPE is < $20/kWh which meets the proposed cost ...
