Abstract: A multistage energy utilization system based on electricity-heat-hydrogen-methane coupling is connected with a power grid, a heat-supply network and a gas-supply network. The system includes a renewable energy resource module, a hydrogen energy storage module, a heat storage module, a gas fired-boiler module, a methane reactor module and a carbon capture and storage (CCS) module. The renewable energy resource module is connected with the power grid and the hydrogen energy storage module. The hydrogen energy storage module is connected with the power grid, the heat-supply network and the methane reactor module. The methane reactor module is connected with the hydrogen energy storage module, the CCS module and the gas-supply network. The gas fired-boiler module is connected with the gas-supply network. The hydrogen energy storage module, the CCS module and the methane reactor module are integrated to improve energy utilization and consumption level of renewable energy resources.
