What is thermal energy storage? Thermal energy storage means heating or cooling a medium to use the energy when needed later. In its simplest form, this could mean using a water tank for heat storage, where the water is heated at times when there is a lot of energy, and the energy is then stored in the water for use when energy is less plentiful.
Fluid flow is based on % full, not absolute numbers. The greater the % difference, the faster the flow. A tank with 250 steam flows just as slowly as a pipe with 1 steam (which is pretty darned slowly). There is a fairly significant exception, though: Pumps. Tank to tank pumping is substantially faster than tank to pipe or pipe to pipe pumping.
While a steam tank holds 2.4~ish GJ, each heat pipe unit stores 0.5 GJ and a reactor 5GJ. So there''s actually a massive energy buffer even with no tanks. Personally I just use a steam tank to gauge how much steam is inside the pipes, sending the result to the circuit network and eventually inserting fuel only when steam is lower than like 20k.

A 500°C steam storage tank is 222 times more space efficient at storing energy than an accumulator as of v0.16.51 (215.56 times if ambient 15°C is taken into account but I didn''t notice it having an effect in testing) and with Factorio physics, steam doesn''t cool down.
For the intermittence and instability of solar energy, energy storage can be a good solution in many civil and industrial thermal scenarios. With the advantages of low cost, simple structure, and high efficiency, a single-tank thermal energy storage system is a competitive way of thermal energy storage (TES). In this study, a two-dimensional flow and heat transfer
energy is stored in another storage medium [4]. Steam accumulation is the simplest heat storage technology for DSG since steam is directly stored in a storage pressure vessel, i.e., steam accumulator, in form of pressurized saturated water [5]. Discharging from steam accumulators usually takes place from the top part of the

Thermochemical storage tanks store thermal energy as chemical bonds in a reversible reaction. When the solar collector heats up, it triggers a chemical reaction, storing the heat as a high-energy compound. When heat is required, the reaction can be reversed, releasing the stored heat.
