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.
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.
What is thermal energy storage integration?
Thermal energy storage integration is a promising method for enabling flexible operation of such plants without modifying the boiler operation or reducing the CO2 recovery rate.
Is thermal storage integration a flexibilization measure for coal-fired power plants?
For coal-fired power plants without CO2 capture, thermal storage integration as a flexibilization measure has been widely studied. A summary of energy storage technologies and integration options that have been investigated in this context is given in the next three paragraphs.
Does thermal storage provide power plant flexibility?
In these studies, the main purpose of the thermal storage is to ensure continuous heat supply for the capture process, not to provide power plant flexibility. For coal-fired power plants without CO2 capture, thermal storage integration as a flexibilization measure has been widely studied.
What are some examples of heat extraction in power plants?
The literature also contains examples of direct and indirect heat extraction in the feedwater section as well as high-pressure and low-pressure storage tanks in the steam section of power plants. One example is a concept presented by Jentsch et al. of a displacement storage arranged parallel to the high-pressure preheating section.
