Abstract

The invention relates to a chemical looping combustion-based hydrogen energy storage, combined heat and power generation and CO<2> capture system and method. The system comprises a chemical looping combustion system, a gas turbine power generation system, an auxiliary combustion system and a waste heat recovery and utilization system, wherein the chemical looping combustion system is used for producing hydrogen and high-temperature gas, and realizing adsorption and separation of CO<2> in a combustion product; the gas turbine power generation system generates power by utilizing the high-temperature gas generated by the chemical looping combustion system or the auxiliary combustion system; the auxiliary combustion system is accessed under the condition of a relatively large power load, so that gas temperature of an inlet of a gas turbine is increased and the power generation efficiency is improved; and the waste heat recovery and utilization system can realize high, medium and low temperature gradient utilization of waste heat resources of the gas in the system, produce steam required in the system and supply heat. According to the system, an output ratio of power generation and hydrogen energy storage can be adjusted and controlled by controlling reaction conditions while CO<2> capture and heat supply are carried out, and production is carried out according to power demands, so that dynamic efficiency of energy utilization is improved.

Description

technical field [0001] The invention relates to the technical field of energy and environment, in particular to a hydrogen energy storage based on chemical looping combustion, cogeneration of heat and power and CO 2 Systems and methods of capture. Background technique [0002] At present, the main way of energy consumption is the oxidation and heat release of carbon-containing fossil fuels. With the increasing global energy consumption and the increasing concentration of carbon dioxide in the atmosphere, the trend of global warming is gradually intensifying. Under the current situation of increasingly stringent environmental protection policies in the international scope, CO 2 Gas emission reduction is particularly important. At the same time, as the supply and demand load of the energy system increases, how to adjust and control the load of the system energy storage to maximize the overall dynamic efficiency and economic benefits of the system has become an urgent problem...
