Studies have shown that 89% of the pollution that exists on Earth today is due to the use of fossil fuels. To green the world and provide clean, sustainable energy, engineers and scientists have been looking for a pollution-free, readily available fuel choice for the transportation and industrial sectors. The hydrogen gas economy has been chosen as the greatest solution. This hydrogen economy has the potential to displace the need for fossil fuels. This review study discourses the possibility of using hydrogen gas as an energy source to create a cleaner planet through decarbonization. The role of hydrogen as the foundation for greener and cleaner energy in the industrial and transport sectors, utilizations on its zero emissions, increasing electrification through fuel cell technology, and profits of hydrogen economy on the environment were substantially discussed. With a hydrogen economy, planet earth will reach its natural state of equilibrium.enClimate Change: Cleaner Earth: Clean Energy: Clean Environment: Pollution FreePresentation
