Abstract The integration of large-scale renewable energy with the electrical grid is improving the ecological balance and minimizing impact of human on the environment, however, it is throwing new challenges such as ramp up/ramp down, forecasting, stability etc, and particularly, requirement of energy storage. Even though large scale batteries and pumped storage plants provide some support in this regard, batteries have their own problems such as very low lifetime, costly, disposal issues, performance deterioration and limited capacity of pumped storage. Converting electrical energy produced from renewable energy sources into hydrogen through electrolysis process may be a game changer in energy sector as the same address the various issues such as renewable energy curtailment, long-term energy storage, use of heavy metals, carbon foot print, requirement of fossil fuel, requirement of hydrogen for other sectors etc. In addition, the energy produced from hydro power plants, not having storage facility, can also be utilized in production of hydrogen production via electrolysis process and can be stored for its future use. In addition, the hydrogen-having applications in various industries such agriculture/fertilizer, chemical, petroleum refining, etc has-huge demand, however, as per International Renewable Energy Agency (IRENA, 2019) report, only 4% of global hydrogen requirement is met from electrolysis process and the rest is from fossil fuel.
