Does molten salt thermal storage work in a coal-fired power plant?

This work proposes a novel system of molten salt thermal storage based on multiple heat sources (i.e., high-temperature flue gas and superheated steam) integrated within a coal-fired power plant. To evaluate the performance of the thermal energy storage system, simulation models were established, and exergy analysis was conducted.

Can thermal energy storage improve the flexibility of coal-fired power plants?

At present, large-scale energy storage technology is not yet mature. Improving the flexibility of coal-fired power plants to suppress the instability of renewable energy generation is a feasible path. Thermal energy storage is a feasible technology to improve the flexibility of coal-fired power plants.

Are energy storage technologies a viable solution for coal-fired power plants?

Energy storage technologies offer a viable solution to provide better flexibility against load fluctuations and reduce the carbon footprint of coal-fired power plants by minimizing exergy losses, thereby achieving better energy efficiency.

How does a coal-fired power plant use energy storage?

A detailed dynamic simulation model for a coal-fired power plant is developed. The integration of a steam accumulator into the water-steam cycle is presented. Charging the energy storage leads to a (minimum) load reduction of up to 7.0%. Discharging the energy storage leads to an additional net power of up to 4.3%.

Can a steam accumulator be integrated into a coal-fired power plant?

For this reason, the integration of a steam accumulator into a coal-fired power plant is considered within the scope of this paper, as a Ruths storage integration promises further optimization of the short-term dynamic behavior, especially regarding fast reaction times of the net power when charging or discharging the storage vessel.

Can heat storage transform coal-fired power plants?

This article provides a review of the research on the flexibility transformation of coal-fired power plants based on heat storage technology, mainly including medium to low-temperature heat storage based on hot water tanks and high-temperature heat storage based on molten salt.
