The current load balance in the grid is managed mainly through peaking fossil-fuelled power plants that respond passively to the load changes. Intermittency, which comes from renewable energy sources, imposes additional requirements for even more flexible and faster responses from conventional power plants. A major challenge is to
In a concentrating solar power (CSP) system, the sun''s rays are reflected onto a receiver, which creates heat that is used to generate electricity that can be used immediately or stored for later use. This enables CSP systems to be flexible, or dispatchable, options for providing clean, renewable energy. Several sensible thermal energy storage
A molten salt storage inventory of 28,500 tons is cycled between 385°C and 295°C, the thermal capacity of this system is 1050 MWh ( Relloso and Delgado, 2009 ).
