Coal-electricity-storage coupling

Repurposing coal power plants could save costs and reduce carbon emissions using the existing infrastructure and grid connections. This paper investigates a retrofitting strategy that turns coal power plants into thermal energy storage (TES) and zero-carbon data centers (DCs).. Repurposing coal power plants could save costs and reduce carbon emissions using the existing infrastructure and grid connections. This paper investigates a retrofitting strategy that turns coal power plants into thermal energy storage (TES) and zero-carbon data centers (DCs). The proposed capacity. . In this context, this paper identifies the synergies among flexibility options under restrictions on transmission expansion or increased costs of energy storage. Itcontributestodeterminingwhetherinvestments in energy storage and/or transmission expansion offer the least-cost transition and. . Transformation from electricity to gases and vice versa can add further storage capacity and flexibility to the energy system. Research indicates that coupling different sectors in this way would lower the overall cost of decarbonising the energy system. The EU has reformed its electricity markets.
