Green ammonia is produced by using renewable energy sources to electrolyze water, generating hydrogen, which is then combined with nitrogen from the air through the Haber-Bosch process. It can be used as a carbon-free fertilizer, a fuel for power generation, and a potential energy carrier for hydrogen. Its production and use contribute to reducing greenhouse gas emissions.
E-ammonia is produced by directly synthesizing ammonia from hydrogen generated through water electrolysis and nitrogen from the air, using renewable energy. It serves as a sustainable fertilizer and can also be utilized as a fuel or energy carrier, facilitating the transition to a low-carbon economy. E-ammonia offers a way to store and transport renewable energy efficiently.
