Supercapacitor-based energy storage for microgrids avoids over-sizing. Micro-grid engineering becoming a macro profession.
Supercapacitor-based energy storage, on the other hand, is much simpler. This technology stores energy on the surface of the electrolyte, which means there is no chemical reaction. “Electrical energy comes in and is stored as electrical energy. It releases electrical energy back into electricity when discharged,” Ghani explained. Still supercapacitor-based energy storage hasn’t been used before because it has its …
