Abstract

The invention discloses a comprehensive energy source system based on aluminum fuel and a working method of the comprehensive energy source system. The system comprises an aluminum fuel preparation and combustion subsystem, a steam Rankine cycle power generation subsystem and a hydrogen separation subsystem. By effectively coupling energy storage based on the aluminum fuel, aluminum combustion power generation, steam Rankine cycle, hydrogen production and the like, the system has the advantages that the energy storage density is high, the energy storage period is long, permanent storage can beachieved, fuel recycling is free of consumption, poly-generation of electric power and hydrogen can be achieved, and global energy trade can be conveniently carried out.

Description

technical field [0001] The invention belongs to the technical field of green power generation and advanced energy storage, and specifically relates to an aluminum fuel-based comprehensive energy system and a working method thereof. Background technique [0002] With the increasingly serious situation of global air pollution and climate warming, the traditional power generation system based on fossil energy will face unprecedented pressure and challenges. From a global perspective, countries are trying to increase the proportion of renewable energy in their power structure. In the future, the development trend of the world's energy field will inevitably be that renewable energy will gradually replace fossil energy. However, due to its intermittent, unstable and uncertain characteristics, renewable energy seriously hinders the development of renewable energy power generation. In order to replace fossil energy with renewable energy in the future, we must rely on the developme...
