However, the Haber process for synthesizing ammonia has high energy consumption, and the energy consumption of the whole process is aboutAccounting for 1% of the total annual energy consumption of the world; meanwhile, the high-purity hydrogen used by the Haber method mainly comes from natural gas reforming of fossil fuel, and annual CO 2 The discharge amount is up to 4.5 hundred million tons.
