6 FAQs about [Coal power generation and energy storage]

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.

Can liquid CO2 energy storage improve the flexibility of coal-fired power plants?

A novel integration system of liquid CO2 energy storage and coal-fired power plant based on coal drying is proposed to improve the flexibility of coal-fired power plants further.

Why do we need a coal power system retrofit?

Our results show that coal units persist even at very high renewable penetrations, and retrofits help them reduce power system costs, enable renewable energy integration, and marginally cut emissions. Smaller coal units become peaker rather than baseload units, providing the power system with flexibility rather than just energy.

How does the integrated system affect the economics of coal-fired power plants?

The economics of the integrated system is significantly affected by the market prices of coal and hydrogen. The integrated system has significant advantages in reducing energy consumption and carbon emissions with higher economic performance, which can provide guidance for the low-carbon transition of coal-fired power plants.

Can energy storage systems be integrated with fossil power plants?

Several studies have been reported in the literature, particularly on power plant system modeling, and integration of sensible and latent heat-based energy storage systems with fossil power cycles , . Liquid air energy storage (LAES) is another form of energy storage that has been proposed for integration with fossil power plants.

Can flexible coal units improve the power system?

Our results show that flexible coal units could help the power system achieve multiple economic and environmental benefits simultaneously, especially at high levels of VRE penetration; these benefits include a reduction in electricity curtailment from VRE sources and lower GHG emissions. These retrofits also reduce power system costs.
