Green Hydrogen and India’s Clean Energy Transition

Green hydrogen is hydrogen produced through electrolysis of water using renewable energy sources such as solar and wind.
The process emits zero carbon dioxide, making it central to net-zero strategies and India’s National Green Hydrogen Mission (2023).

Why Seawater is Being Explored (“Blue Thinking”)

Producing 1 kg of green hydrogen requires around 9–10 litres of demineralised freshwater.

Key concerns:
India is already water-stressed.
Large hydrogen projects may compete with drinking water and agriculture.

Using Sea-Water for Green Hydrogen Production

Using seawater can reduce pressure on land-based water systems. Emerging approaches include:

• Electrolysis using pre-desalinated seawater.
• Direct seawater electrolysis technologies (in early stages of development, issues of corrosion and efficiency).
• Coastal hydrogen hubs can integrate renewables + desalination + electrolysis to minimise land-water stress.
