Energy is an important material basis for human survival and the development of civilization. The energy revolution promotes the progress of human civilization. The first energy revolution allowed coal to replace firewood through the large-scale application of steam engines; the second energy revolution brought mankind from the coal age to the oil age through the invention and use of generators and internal combustion engines. However, in the above two energy revolutions, traditional primary non-renewable energy sources such as coal, oil and natural gas are widely used, and a large amount of SO2, CO, CO2 and other toxic and harmful gases and a large amount of solid waste will be generated during the utilization process, causing environmental pollution. . At present, the third energy revolution is gestating and emerging. By reducing the use of primary energy, the development of green and sustainable energy such as hydrogen energy has become a common voice worldwide.
