Thermo-economic analysis of steam accumulation and solid thermal energy
Most solar power plants, irrespective of their scale (i.e., from smaller [12] to larger [13], [14] plants), are coupled with thermal energy storage (TES) systems that store excess solar heat during daytime and discharge during night or during cloudy periods [15] DSG CSP plants, the typical TES options include: (i) direct steam accumulation; (ii) indirect sensible TES;
Steam Accumulators
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.
