As global population increases with time, thus the global energy need also increases. It is important to switch over to a more environmentally friendly energy source. Due to heavy consumption of fossil fuel, global warming reaches to its new level. Now it is essential to investigate to new alternative energy sources. This study aims at hydrogen fuel to be used as an energy alternative. There are various hydrogen production processes which are classified on how friendly they are to the environment. In this paper an attempt has been made to study & review the best hydrogen fuel production method among various processes. Also, we have discussed a green initiative towards innovative and sustainable development in energy consumption. As per our conclusion, green hydrogen production is the best method. Where in green hydrogen production method electrolysis of water is carried out with help of renewable energy such as solar energy, wind energy etc.
