An Electrochemical Haber-Bosch Process Ammonia is the primary chemical intermediate in the fertilizer industry and an important carbon-free energy carrier. Currently, however, ammonia constitutes the most energy-intensive chemical worldwide. Using the feed gases of the conventional Haber-Bosch process, we combined the main stages of an ammonia
