This review describes several potential technologies, in current conditions and in the future, for ammonia production, storage and utilization.
Abstract To achieve carbon neutrality, hydrogen and ammonia are considered promising energy carriers for renewable energy. Efficient use of these resources has become a critical research focus. Here we propose an intelligent hydrogen-ammonia combined energy storage system.
Ammonia is currently regarded as one of the most promising storage and transport media for hydrogen. Large quantities of hydrogen can be transported relatively easily in the form of ammonia.
Although ammonia can be used directly for energy applications, its use in conventional fuel cell electric vehicles necessitates decomposition into nitrogen and hydrogen, and the purification of the hydrogen to the composition required for commercial proton exchange membrane fuel cells.
This review systematically summarizes breakthrough advancements in ammonia decomposition technologies, deconstructing the intrinsic characteristics of hydrogen storage via ammonia at theoretical levels.
Ammonia is considered to be a potential medium for hydrogen storage, facilitating CO2-free energy systems in the future. Its high volumetric hydrogen density, low storage pressure and stability for long-term storage are among the beneficial characteristics of ammonia for hydrogen storage.
The objectives of this paper are to identify, evaluate and summarize the key issues and advantages and disadvantages associated with ammonia as an energy carrier for on-board vehicular hydrogen storage.
free process. The paper argues that ammonia, as an energy vector of hydrogen, is preferable to pure hydrogen from economic, environmental, and technological perspectives. It then analyses the available ammonia generation techniques, identifying conditions under which zero-carbon ammonia makes sense economically, and briefly highlights policy
The focus of this research is to understand the scientific and technical aspects of the potential use of ammonia and other related carbon-free energy carriers for hydrogen fuel cell applications.
Although an ultimate ranking of energy storage options is not provided, the hydrogen-ammonia combination arguably emerges as the best option in terms of economics, environmental and social impact, and deployability.
