Beginner: Are steam tanks better at "storing energy" than accumulators?

Nuclear is so cheap that you dont really need to have accumulators for energy storage. The reason we use Steam tanks is that the uranium fuel cell gets used 100% in 200 seconds no matter your energy needs. So people make setups that puts one uranium fuel cell into each of the nuclear reactors (to fully take advantage of the neighbor bonus) and

6 FAQs about [Accumulator energy storage calculation]

How do you estimate the storage capacity of a steam accumulator?

To quickly estimate the storage capacity of a steam accumulator, it is useful to use approximations that do not require the use of steam tables or step-by-step computational procedures. For an estimation, the steam accumulator is assumed to be a volume of water with constant thermophysical properties that undergoes a temperature change.

How much energy is stored in a accumulator?

Transferring heat of the given intensity into the accumulator volume. Daytime storage of energy capacity accounts for: 700·14 = 9.8·10 3 kW hour, or 1.2·10 3 kW hour/°C. During half a month of operation the temperature stagnation reached a value of about 120 °C (for gravel) and 220 °C (for zeolite).

Can a case accumulator store thermal energy during discharge?

Additionally, the two cases were analysed during discharge, in which the heat input was solely from the stored thermal energy. Case-B was able to store almost all available excess thermal energy during the 5 hours of charging (about 93% of available heat for storage), using the same total steam accumulator volume as Case-A.

What are accumulators used for in fluid power systems?

Accumulators have two major functions in fluid power systems: firstly, accumulators are used to stabilise pressure; secondly, accumulators are used as energy storage. So accumulators are for fluid power systems what capacitors are for electrical systems. Accumulators are constructed in various ways and with different means of energy accumulation.

Can steam accumulators be used as thermal energy storage and buffer units?

To solve this problem, steam accumulators (SAs) can be used as thermal energy storage and buffer units. However, it is difficult to promote the application of SAs due to high investment costs, which directly depend on the usage volume. Thus, the operation of SAs should be optimized to reduce initial investment through volume minimization.
