The chapter explores the transformation of coal-fired power plants into sustainable energy facilities through the integration of advanced storage systems. Historically, coal-fired plants operated with inflexible schedules and slow response times, making them unsuitable for modern grids reliant on renewable energy. Re-purposing these plants into Thermal Storage Power Plants (TSPP) replaces coal-fired combustion with molten salt thermal energy storage, leveraging existing infrastructure to store renewable energy for electricity generation. To enhance flexibility, second-life batteries (SLBs), repurposed from electric vehicles, are integrated. These batteries, despite reduced capacity, provide cost-effective, sustainable energy storage for medium-term demands, extending their lifecycle through optimized conditions. Flywheels are also included, offering instantaneous power output to stabilize the grid while reducing SLB degradation. The resulting Hybrid Energy Storage System (HESS) combines TSPP, SLBs, and flywheels under a centralized control scheme. Flywheels manage short-term fluctuations, SLBs address intermediate demands, and TSPPs provide long-term, stable power. This system improves efficiency, minimizes degradation, and ensures grid stability. Case studies and examples demonstrate the potential of this model, highlighting its economic and environmental benefits. This innovative approach aligns with global decarbonization goals, offering a pathway to modernize energy systems while repurposing obsolete infrastructure effectively.

摘要

The chapter explores the transformation of coal-fired power plants into sustainable energy facilities through the integration of advanced storage systems. Historically, coal-fired plants operated with inflexible schedules and slow response times, making them unsuitable for modern grids reliant on renewable energy. Re-purposing these plants into Thermal Storage Power Plants (TSPP) replaces coal-fired combustion with molten salt thermal energy storage, leveraging existing infrastructure to store renewable energy for electricity generation. To enhance flexibility, second-life batteries (SLBs), repurposed from electric vehicles, are integrated. These batteries, despite reduced capacity, provide cost-effective, sustainable energy storage for medium-term demands, extending their lifecycle through optimized conditions. Flywheels are also included, offering instantaneous power output to stabilize the grid while reducing SLB degradation. The resulting Hybrid Energy Storage System (HESS) combines TSPP, SLBs, and flywheels under a centralized control scheme. Flywheels manage short-term fluctuations, SLBs address intermediate demands, and TSPPs provide long-term, stable power. This system improves efficiency, minimizes degradation, and ensures grid stability. Case studies and examples demonstrate the potential of this model, highlighting its economic and environmental benefits. This innovative approach aligns with global decarbonization goals, offering a pathway to modernize energy systems while repurposing obsolete infrastructure effectively.
