Most efficient alkaline electrolyzers today consume ~50 kWh of electricity and 10 liters of fresh water to produce 1 kg of hydrogen. Therefore, if all the ~5 million tons of green hydrogen production target by 2030 were to be achieved via alkaline electrolysis, India would require ~50 billion liters of fresh water and 250 billion kWh of electricity supply from renewable sources of energy, primarily wind and solar PV. This translates to ~115 GW of installed renewable power generation capacity @ 25% CUF (for hybrid round-the -clock supply). To get a sense of this scale, the current all India installed capacity of renewable power generation is ~106 GW as of Feb 20221.
India’s green hydrogen market is currently in the nascent stages of development. The supply chain for green hydrogen needs sufficient economies of scale and innovation to achieve competitiveness through 2030….
