The massive integration of renewable energy sources into electricity grid will pose challenges for the grid stability due to their intermittent nature. This creates a need for innovative energy conversion and storage as supporting technologies. In this presentation, we will report a solid oxide fuel cell-battery hybrid electrochemical system that can quickly respond to fuel supply interruption or power demand surges. In the fuel cell mode, the system works as a conventional fuel cell, converting chemical energy stored in fuels into electrical energy. In case of fuel supply interruption or power demand surges, the system switches on the battery mode by releasing hydrogen from metal hydride proximal to the anode to maintain the power delivery. This dual-mode electrochemical system represents a promising approach for load leveling in the electricity grid.
