Ammonia has a potential as carbon-free and high-energy density compound for chemical storage of renewable energies and its synthesis from green H. 2. requires to be as
Synthetic ammonia, manufactured by the Haber–Bosch process and its variants, is the key to securing global food security. Hydrogen is the most important feedstock for all synthetic ammonia processes. Renewable
NH 3 has several advantages over other H 2 storage and transportation candidates, including a high hydrogen storage capacity (17.7 wt%), relatively mild liquefaction conditions (0.86 MPa at 20 ), a high volumetric energy density (108 kgH 2 m −3), carbon-free nature, and the ability to be mass produced via the well-known
In addition, Raju focused on the energy storage applications of ammonium metal phosphates in SCs and rechargeable batteries. However, other ammonium salt materials such as ammonium vanadate or ammonium molybdate have not been reviewed yet [7] .
The ammonia energy application status is reviewed from four aspects: ammonia internal combustion engines, ammonia gas turbines, ammonia-burning boilers, and ammonia-hydrogen fuel cells. Moreover, the status quo of the synthetic ammonia industry, development trend of the ammonia energy industry, and development plans of the
The design and optimization of an ammonia synthesis system is also presented in this review for ammonia-based solar thermochemical energy storage
Ammonia, a molecule that is gaining more interest as a fueling vector, has been considered as a candidate to power transport, produce energy, and support heating applications for decades. However, the particular characteristics of the molecule always made it a chemical with low, if any, benefit once compared to conventional fossil fuels.
However, the difficulties of hydrogen storage and transport limit its application [14]. Hydrogen energy carriers such as methanol, ammonia, hydrazine, etc., can be applied to overcome the abovementioned challenges.
To this end, an ammonia-based energy storage system is proposed. It utilizes a pressurized reversible solid-oxide fuel cell for power conversion, coupled with external ammonia synthesis and decomposition
Ammonia-based thermochemical energy storage systems have emerged as a promising option, utilizing solar energy to dissociate ammonia into hydrogen and
Ammonia, being one of the most promising media for hydrogen storage, is regarded as an ideal carbon-free energy carrier. Moreover, ammonia exhibits critical
For the synthesis of ammonia, we describe the different methods, i.e., the Haber–Bosch method, the electrocatalytic method, the photocatalytic method, the plasma-assisted
Ammonia has a potential as carbon-free and high-energy density compound for chemical storage of renewable energies and its synthesis from green H2
To mimic the natural production of ammonia and to establish green ammonia as an energy and chemical vector in future renewables utilization, it is

Ammonia, acknowledged as an energy storage medium in various countries, benefits from a well-developed transport and distribution infrastructure, making it a feasible option for fuel applications. The recently developed NH 3 production and distribution grid enables adequate ammonia storage and re-distribution at a lower economic cost.
Ammonia is significant in various industrial and transportation applications: carbon-free fuel, synthetic fertilizers, mining, medicines, water treatment, polymers, and textiles. In recent times, the utilization of green ammonia as an environmentally sustainable fuel with zero carbon emissions has garnered significant
