One potential energy carrier that could be pivotal in attaining sustainable development is hydrogen, which has recently gained a lot of attention. In order to achieve global objectives for ecological preservation, economic growth, and energy stability, it provides a flexible, clean, and extensible energy source that can lessen dependency on fossil fuels. Hydrogen has many applications in the energy sector, such as a green energy source, a backup power supply for the grid, energy storage using renewable sources, and hydrogen fuel cells. Potential transportation options include fuel cell cars, aircraft powered by hydrogen, and environmentally friendly cargo fuels such as ammonia. The industrial applications include chemically producing methanol and ammonia, producing cement with reduced carbon emissions, and using direct reduced iron from hydrogen in steelmaking, all of which are environmentally friendly. For agriculture applications, a more sustainable farming practice that reduces the environmental impact of food production is the use of fertilizers manufactured by hydrogen. Hydrogen is utilized for the purpose of providing fuel for environmentally friendly heating systems and providing power for homes that are both efficient and environmentally neutral. Hydrogen is used for residential projects as well. Hydrogen is employed as a battery backup for vital infrastructure, including healthcare institutions, as a result of innovations in medical devices. Significant sectors benefit from hydrogen’s potential to encourage innovation and sustainability.
