where NSTOR = integer (VSTOR/VMAX) + 1
EMPTY = number spare tanks
VSTOR = VSTREF*(ESTOR/ESTREF)

CSTREF ($) and CSTRMD ($) are reference containment
and media costs, respectively, for a system of volume
VSTREF (m3) and stored energy capacity ESTREF (watt-hrs)
VMAX (m3) is the maximum practical volume.

Parameter for heat exchanger cost:
= 0, cost scales with thermal power;
# 0, cost scales with individual heat exchanger areas.
Default: ICHE = 0

Heat exchanger cost parameters for scaling with thermal
power; CHTXCHG, total heat exchanger cost in $, given by:
CHTXCHG = CHEREF' (PTH/PHEREF)XH"r
where CHEREF ($) and PHEREF (watts) are the cost and
associated thermal power of a reference design.
