Can thermal energy storage be integrated into coal-fired steam power plants?

In the FLEXI- TES joint project, the flexibilization of coal-fired steam power plants by integrating thermal energy storage (TES) into the power plant process is being investigated. In the concept phase at the beginning of the research project, various storage integration concepts were developed and evaluated.

Should thermal energy storage be integrated into power plants?

For conventional power plants, the integration of thermal energy storage (TES) into the power plant process opens up a promising option for meeting future technical requirements in terms of flexibility while at the same time improving economic efficiency.

What is steam accumulation?

Authors to whom correspondence should be addressed. Steam accumulation is one of the most effective ways of thermal energy storage (TES) for the solar thermal energy (STE) industry.

What is a steam accumulation tank?

Steam accumulation tanks are generally cylindrical with elliptical ends and are manufactured from boiler plate. One of the main advantages is that the storage fluid is water, avoiding uncertainty in the price of the storage medium.

Why are steam accumulators required for thermal energy storage?

The application of steam accumulators is mandatory for thermal energy storage which use direct steam generation technology. In the first generation of these plants the saturated steam from the accumulators is lead directly to the turbine.

Can steam accumulators be used in a nuclear power plant?

Steam accumulators can also be applied for heat storage in a nuclear power plant with light water reactors as first reported in the year 1970 . This solution foresees a high pressure accumulator (charged with fresh steam) and lower pressure accumulators (charged with steam from exit of high pressure turbine).
