This study provided valuable insights into the feasibility of green hydrogen production in Morocco, which could contribute to the country's energy transition towards a more sustainable future [15]. With the abundance of research and projects in the field, hydrogen and ammonia have emerged as highly promising solutions to achieve net-zero goals in various sectors, including power, transport, heat, and energy storage [16]. It is an opportune time to invest in green hydrogen and ammonia production technologies, as the potential applications of hydrogen expand across multiple industries. From power generation to manufacturing processes in sectors such as steelmaking and cement production, from fuel cells for electric vehicles to heavy transport such as shipping, and from green ammonia production for fertilizers to applications in cleaning products, refrigeration, and electricity grid stabilization, the possibilities for hydrogen utilization are vast. In our comprehensive review, we delve deeply into the latest research and developments in these areas, exploring the transformative potential of green hydrogen and ammonia in shaping the future of energy production. The paper is organized into sections to provide a systematic analysis: Section 2 offers an overview of current hydrogen production technology, while Section 3 investigates existing hydrogen storage systems. Section 4 focuses on conventional ammonia production methods, followed by the exploration of advancements in ammonia manufacturing technology in Section 5. Furthermore, we explore the integration of artificial intelligence (AI) into the manufacturing process, examining how it can enhance efficiency and optimize hydrogen and ammonia production. The benefits of incorporating 3D printing technology, such as reducing material waste and enabling design flexibility, are discussed in Section 8. We also explore how additive manufacturing (AM) can create complex geometries, structures, and catalysts, leading to enhanced efficiency and performance in hydrogen and ammonia generation.
