Abstract

The invention relates to a system for producing hydrogen and ammonia by using clean energy. The method is characterized in that a water electrolysis hydrogen production technology and an ammonia synthesis technology are combined, clean energy is coupled for power generation, hydrogen energy is stored and transported in the form of liquid ammonia while zero-carbon-emission hydrogen production is achieved, and the problems that hydrogen energy storage and transportation are difficult, ammonia synthesis industry carbon emission is high, and a hydrogen energy production place and a terminal application place are mismatched are effectively solved; and the application scene of hydrogen energy is greatly widened.

Description

technical field [0001] The invention relates to a clean energy hydrogen production and ammonia production system, belonging to the fields of green hydrogen energy and green chemical industry. Background technique [0002] With the national goal of "carbon peaking" and "carbon neutrality", the proportion of clean energy in energy consumption will increase significantly. Hydrogen energy has the advantages of high calorific value, zero emission, no pollution, and wide application in clean energy. It is the most potential alternative energy at present. At this stage, hydrogen production from fossil energy is still the main method of hydrogen production, which cannot achieve true zero-emission. With the development of clean energy utilization technology, clean energy hydrogen production is the main way of green hydrogen production in the future. Hydrogen production from clean energy is mainly through the hydrogen production technology of water electrolysis, which converts clean ...
