When steam is supplied, it condenses in the water contained in the storage tank, causing the water level to rise and creating excess pressure in the tank. Together with the tank insulation, this contributes to the energy
Similar to the storage concepts discussed previously, steam accumulators use a liquid medium to store sensible heat. Thus, the name steam accumulator could be misleading; in fact, hot liquid water is used as the storage medium.
A steam accumulator is, essentially, an extension of the energy storage capacity of the boiler (s). When steam demand from the plant is low, and the boiler is capable of generating more steam than is required, the surplus steam is injected into a mass of water stored under pressure.
With new technology and new material, it is now possible to store solar energy using steam in a cost-effective and efficient manner, making solar energy production more lucrative and reliable.
The tank is about half-filled with cold water and steam is blown in from a boiler via a perforated pipe near the bottom of the drum. Some of the steam condenses and heats the water. The remainder fills the space above the water level. When the accumulator is fully charged the condensed steam will have raised the water level in the drum to about three-quarters full and the temperature and pressure will also have risen.
An innovative system being developed at the U.S. Department of Energy''s (DOE) Argonne National Laboratory can quickly store heat and release it for use when needed, surpassing conventional storage options in both flexibility and efficiency.
By storing excess steam and releasing it when needed, a steam accumulator helps maintain a balanced and efficient steam supply, reducing energy consumption and improving overall system performance.

The accumulator allows the steam boiler plant to operate under steady state load conditions by storing steam at times of low steam consumption, and releasing it to meet peak demands (in this case when the autoclaves are switched on).
With its capability to store thermal energy during peak generation times, steam energy storage ensures that ample supply meets energy demands, providing essential grid stability.
When steam is supplied, it condenses in the water contained in the storage tank, causing the water level to rise and creating excess pressure in the tank. Together with the tank insulation, this contributes to the energy conservation of the heat transfer medium.
