By virtue of not containing carbon, ammonia (NH3) is considered a zero-carbon fuel. This book provides an introduction and technological context for the current role of ammonia as a fertilizer and chemical, as well as ammonia as a zero-carbon fuel and hydrogen carrier. The book emphasises industrial aspects of low-emission ammonia with scientific explanations for low-carbon fossil ammonia production and renewable ammonia production via various electrolysis technologies, as well as storage, handling, and utilization of ammonia for energy applications, while also covering safety, regulations, environmental considerations, business methods, and policy. Thus, this book presents the state-of-the-art of relevant technologies in the energy transition. All in all, ammonia production is set to triple over the coming decades, while the ammonia infrastructure is expected to scale up by an order of magnitude. Low-emission Ammonia Production and Utilization is an invaluable reference source for academics and industry workers, as well as policy makers, investigating all relevant sustainable ammonia production and utilisation technologies.
