The storage tank of a steam accumulator must be able to withstand the pressure of the water, including hydrostatic pressure. The storage tank accounts for the larg-est portion of the capital cost of a steam storage tank. One focus of the design is to minimize the mass of the storage tank for safe operation.
According to [Goldstern1963], dry steam storage tanks with volumes up to 3000 m 3 have been built for maximum steam pressures of 1.2 bar. To avoid the pressure drop during discharge, the bell accumulator with variable storage volume was developed. Similar to a gasometer used to store low-pressure natural gas, the bell floats on a water reservoir.
For low steam pressures, there is the possibility of direct storage of superheated steam, but the low storage density of steam requires large volumes. According to [Goldstern1963], dry steam storage tanks with volumes up to 3000 m 3 have been built for maximum steam pressures of 1.2 bar.

The use of prestressed cast iron tanks was proposed in [Gilli1977] as an alternative to welded steel tanks in large-scale steam storage for power plant applications. The use of underground caverns for the storage of pressurized liquid water was presented in a feasibility study [Dooley1977].
