Techno-Economic Analysis of Packed Bed Type Thermal Batteries for Surplus Renewable Energy Storage
Abstract: Low carbon electricity from renewables will form the bed rock of the energy transition necessary for climate change mitigation. However, variable renewable generators suffer from intermittency and variability – there can be large surplus power available at times which cannot be dispatched to the grid. At many times, the practice is to curtail surplus renewable output, which is wasteful and not economic. There are also phases when generation is not …
