Steam As Energy Storage – Solar Energy and Power
Just like any other energy storage technology, steam as energy storage works by charging and discharging. The Charge – The charging process involves filling the steam storage tank half-full with cold water. Thereafter, steam generated through solar heating is blown into the tank through perforated pipes located near the bottom of the tank.

From a modelling standpoint, tank-exchanger assemblies can be categorised into two fundamental configurations as shown in Fig. 2.The exchanger may be situated on either the source or sink side. A source-side exchanger, see Fig. 2 a, is typically found in solar or heat pump systems, while a sink-side exchanger, see Fig. 2 b, is

1x full storage tank of 500deg steam = 2.425 GJ of energy. Heat Ex & Heat Pipes store up to 500MJ each. Each Reactor Core stores up to 5GJ. Realistically you would not want the HX, HP, & cores at max temp (probably = wasting fuel). However, as they do store a fair amount & you always need to build some anyway, it means you need less steam tanks

OverviewHistoryChargeDischargeSee alsoSourcesExternal links
A steam accumulator is an insulated steel pressure tank containing hot water and steam under pressure. It is a type of energy storage device. It can be used to smooth out peaks and troughs in demand for steam. Steam accumulators may take on a significance for energy storage in solar thermal energy projects. An example is the PS10 solar power plant near Seville, Spain and one planned for th

Using steam storage tanks instead of accumulators
Accumulator to solar ratio is 0.84 and accumulators store 5MJ. 0.84 * 5 = 4.2, so for every solar panel we need 4.2MJ of storage. One storage tank of 165 degree steam holds 750MJ / 4.2 = 178.571428571 solar panels per steam tank. For 1 solar panel you thus need 1 / 178.571428571 steam tanks or 0.056, same as your result.
