Green Hydrogen and Water Management in India

India is accelerating its clean energy transition and one of the most promising solutions in this journey is green hydrogen. The Government of India’s National Green Hydrogen Mission aims to make the country a global hub for hydrogen production, usage, and export. However, while green hydrogen has the potential to reduce carbon emissions and support energy security, its success is closely tied to a critical resource: water — emphasizing the strong connection between green hydrogen and water management.

This blog explores the relationship between green hydrogen and water management, and highlights how organizations like KalyxX India are contributing to sustainable water solutions needed for the future.

What is Green Hydrogen?

Green hydrogen is produced by splitting water (H₂O) into hydrogen and oxygen using renewable energy sources such as solar and wind. This process, known as electrolysis, does not produce carbon emissions, making it a clean alternative to fossil fuel-based hydrogen. This strengthens the importance of green hydrogen and water management, as water is the key resource needed for producing hydrogen sustainably.

Where Can Green Hydrogen Be Used?

• Steel and cement industries
• Fertilizer production
• Shipping and aviation fuels
• Electric grid energy storage
• Heavy transportation

Why Water Plays a Key Role in Green Hydrogen Production

Hydrogen production using electrolysis relies on water as a primary raw material. To produce 1 kilogram of green hydrogen, around 9 liters of purified water are required. For industrial-scale projects, this adds up to a very large volume, making green hydrogen and water management a critical part of planning and sustainability.

Key Water-Related Challenges

Water Availability
Large-scale hydrogen production needs a continuous supply of water. If plants are located in regions already facing water scarcity, it may cause stress on local resources. Hence, smart site selection and water sourcing strategies are essential.

Need for High-Purity Water
Electrolyzers cannot run on regular groundwater or municipal supply. The water must be purified and treated to remove minerals, hardness, salts, and impurities. Without proper treatment, electrolyzer performance drops and equipment can get damaged.

Scaling and Corrosion Issues
If the water is hard or contains minerals, it can cause scaling and corrosion inside pipes, membranes, and electrolysis systems. This reduces efficiency and increases maintenance costs.

Environmental Responsibility
Water usage for hydrogen should not compete with drinking water, agriculture, or local ecosystem needs. Sustainable water intake, recycling, and reuse systems must be built into hydrogen infrastructure from the start.

India’s Green Hydrogen Ambition & Water Implications

India plans to produce 5 million tonnes of green hydrogen annually by 2030. But many renewable-rich regions — like Rajasthan and Gujarat — also face water scarcity. This makes green hydrogen and water management essential, where water treatment, recycling, and efficient use become a core part of the hydrogen deployment strategy.

For Green Hydrogen to scale in India, we need:

• Water treatment and conditioning technologies
• Closed-loop water reuse systems
• Smart site planning near water-rich or desalination-supported regions
• Reduced chemical usage in water processing systems

How Smart Water Management Enables Sustainable Hydrogen

To ensure hydrogen remains green, water usage must be optimized through:

Water Treatment & Conditioning

Water entering electrolyzers must be free from hardness, scaling, and impurities.

Water Reuse & Recycling

Industrial plants must adopt circular water systems to reduce freshwater withdrawals.

Scale Prevention in Pipelines and Plants

Scaling reduces plant efficiency and increases maintenance downtime.

Chemical-Free Treatment Solutions

To reduce environmental footprint beyond just the hydrogen production process.
