Green Hydrogen

Green hydrogen is hydrogen produced through electrolysis of water using renewable electricity, resulting in zero direct carbon emissions. It is distinguished from grey hydrogen (natural gas reforming), blue hydrogen (gas reforming + CCS), and pink hydrogen (nuclear). Green hydrogen is critical for decarbonising hard-to-abate sectors: steel, chemicals, heavy transport, and shipping. India's National Green Hydrogen Mission targets 5 million tonnes annual production by 2030.
