Description

technical field [0001] The present application relates to the technical field of energy systems, in particular to a food waste energy system based on fuel cells and organic liquid hydrogen storage. Background technique [0002] Food waste contains a large amount of organic matter, oil, and nutrients, and has great reuse value. The future food waste treatment plant is a high-quality factory for energy and material recovery, and the development of hydrogen energy technology is a major opportunity for food waste treatment. [0003] At present, the biogas produced by the anaerobic digestion system is mainly used in several ways such as biogas driving blower, biogas power generation, natural gas grid connection and biogas boiler. Among them, the biogas-driven blower directly converts the heat energy of the biogas fuel into kinetic energy, and at the same time outputs waste heat; the biogas power generation converts the heat energy of the biogas fuel into electric energy and heat...
