N2 - The energy scenario is currently undergoing a rapid transition in the pursuit of increasing the share of renewable energy sources in order to reduce the global anthropogenic CO2 emission. However, since several of the renewable energy sources are intermittent in nature, like wind and solar, this intermittency gives rise to several problems in energy production, distribution and management. A novel solution to store and utilize excess energy from intermittent renewable energy sources (IRES) in a combined cycle power plant (CCPP) is introduced. The overall thermal to electricity conversion efficiency of the proposed method is higher as compared to other contemporary energy storage solutions. The techno-economic feasibility analysis of the proposed method indicates that it can lead to annual fuel savings up to approximately 0.8%, thereby saving 3600 tonnes of CO2 emission annually for a typical power plant. The proposed concept paves the way to change the role of a combined-cycle power plant from being solely an energy provider to a contributor in energy storage and energy management.
