Next-generation technologies for the electrosynthesis of ammonia from renewables

Abstract

Ammonia is an important fertiliser for the agriculture, feedstock for the chemical industry, and an emerging high-energy-density carbon-free fuel. One such promising approach is to produce ammonia is the electrochemical synthesis of ammonia from dinitrogen and either dihydrogen or water under close-to-ambient conditions powered by renewable electricity. Replacing the mediator in the nitrogen reduction reaction system might improve the energy efficiency of this technology and facilitate the development of the green ammonia synthesis industry
