India is determined to achieve net zero CO2 emissions by 2070 as promised at the UN Climate Change Conference in Glasgow (COP26). Green Hydrogen is a potential solution to de-carbonize various industrial and automotive sectors. India has declared the ‘National Hydrogen Mission’ on February 17, 2022. The sustainability of hydrogen production, storage, and transport is a critical challenge. Green hydrogen is produced using electrolysis of water with electricity generated by renewable energy. Central to the green hydrogen production process is the electrolyzer technology; Alkaline and Polymer Electrolyte Membrane (PEM) electrolyzers are the promising ones for the same.
