“…[11] Also, producing hydrogen gas from methane requires significant energy inputs, which can increase the cost and reduce the efficiency of the ammonia synthesis process. [46] For these reasons, alternative sources of hydrogen are being explored to reduce the dependence on hydrogen gas in the ammonia synthesis process. In 2022, one study reported that when water was used as a precursor it enabled ammonia synthesis via a mechanochemical method (Figure 2a).…”

Hydrogen is a promising clean energy source, an alternative to fossil fuels, and can potentially play a crucial role in reducing carbon emissions. The transportation and storage of hydrogen are the biggest hurdles to realizing a hydrogen economy. Ammonia is considered to be one of the most promising hydrogen carriers, because of its high hydrogen content and easy liquefaction in mild conditions. To date, ammonia is mostly produced by the ‘thermocatalytic’ Haber‐Bosch process, which requires high temperature and pressure. As a result, it can only produce ammonia in ‘centralized’ manufacturing systems. Mechanochemistry, a newly emerging method for efficient ammonia synthesis, offers potential advantages over the Haber‐Bosch process. Mechanochemical ammonia synthesis under near ambient conditions can be connected with ‘localized’ sustainable energy systems. In this perspective, the state‐of‐the‐art mechanochemical ammonia synthesis processes will be introduced. Challenges and opportunities are also discussed in relation to its role in a hydrogen economy.

“…Electricity from PV panels can also produce hydrogen from electrolyzers in addition to other applications (e.g., space heating or cooling) (Erzen et al 2020;Tukenmez et al 2021;Şevik 2022). Therefore, these systems are currently attracting more attention due to their high performance compared to traditional PV/H 2 systems.…”

Hydrogen energy, as clean and efficient energy, is considered significant support for the construction of a sustainable society in the face of global climate change and the looming energy revolution. Hydrogen is one of the most important chemical substances on earth and can be obtained through various techniques using renewable and nonrenewable energy sources. However, the necessity for a gradual transition to renewable energy sources significantly hampers efforts to identify and implement green hydrogen production paths. Therefore, this paper’s objective is to provide a technological review of the systems of hydrogen production from solar and wind energy utilizing several types of water electrolyzers. The current paper starts with a short brief about the different production techniques. A detailed comparison between water electrolyzer types and a complete illustration of hydrogen production techniques using solar and wind are presented with examples, after which an economic assessment of green hydrogen production by comparing the costs of the discussed renewable sources with other production methods. Finally, the challenges that face the mentioned production methods are illuminated in the current review.
