Hydrogen is a secondary source of energy. It stores and transports vitality delivered from other assets (fossil power, water, and biomass). As the consumption rate of traditional fossil fuels continues to accelerate and environmental issues become increasingly severe, energy demand has become an urgent concern. Further innovation and investment in production, storage, and infrastructure are crucial for a successful transition. In this context, hydrogen has received widespread attention as a clean and efficient energy source. Hydrogen is an energy carrier produced from other sources since it doesn't exist naturally. It can be used as clean fuel in fuel cells, producing heat and power with water vapor as the only by-product. Hydrogen can be made from fossil fuels, biomass, or by passing electricity through water. Some envision a future hydrogen economy, but current production methods are limited and require more efficient technology. In this study, the key technologies of hydrogen storage and the challenges faced by different storage methods such as compression, liquefaction, and absorption in metal hydrides and other complex compounds are discussed and their advantages and disadvantages are clarified. We will also discuss the environmental effects studied in life cycle assessment studies in the field of hydrogen production.
