Ammonia as an Alternative Fuel and Power-to-X Enabler is a holistic guide that aims to support the reader in understanding the technical aspects of ammonia production, storage, utilization, assessing the economic viability and feasibility of integrating ammonia-based energy systems, navigating the regulatory and policy landscape, overcoming safety concerns, and addressing potential environmental impacts. This is supported by case studies, best practices, and real-world examples that illustrate successful integration and highlight lessons learned, thus enabling the successful implementation of ammonia-based solutions.This new volume in the Woodhead Series in Bioenergy is of interest to all those working with ammonia, or with an interest in biofuels, energy carriers, renewable energy, energy systems, transportation, and sustainability, including researchers, advanced students, faculty, engineers, scientists, R&D, industrial practitioners, and policy makers. - Addresses specific challenges and provides solutions related to the adoption and implementation of ammonia as an alternative fuel and energy carrier - Covers production methods of ammonia, ammonia fuel cells, ammonia combustion engines, safety considerations, infrastructure requirements, and policy frameworks - Provides practical guidance, case studies, and best practices on the integration of ammonia in energy systems
