Author : Zero Footprint Industries | Published On : 14 Sep 2026
India is rapidly expanding its clean-energy infrastructure as industries, businesses, and policymakers work toward a lower-carbon economy. With increasing investments in solar and wind power, the country has a strong foundation for developing green hydrogen as an alternative energy carrier.
For anyone interested in India's energy transition, understanding How Green Hydrogen Is Produced in India provides valuable insight into how renewable electricity can be converted into a versatile clean-energy resource.
Green hydrogen has applications across industries such as steel, fertilizers, chemicals, refining, transportation, and energy storage. Its development could also create new opportunities for domestic manufacturing, technology development, and clean-energy exports.
What Does Green Hydrogen Mean?
Green hydrogen is hydrogen produced by using renewable electricity to split water into hydrogen and oxygen through a process called electrolysis.
The basic process is:
Renewable electricity + water → hydrogen + oxygen
When the electricity used by the electrolyzer comes from renewable sources such as solar or wind, hydrogen production can have very low associated greenhouse gas emissions.
Hydrogen can subsequently be compressed, stored, transported, or used directly in industrial and energy applications.
Why Is Green Hydrogen Important for India?
India's energy requirements are increasing as its economy and industrial sector continue to grow. At the same time, the country is working to reduce emissions and increase the contribution of cleaner energy sources.
Green hydrogen can contribute to these objectives by helping address sectors where direct electrification may be difficult.
Its potential advantages include:
-
Reducing dependence on imported fossil fuels
-
Supporting industrial decarbonization
-
Providing a low-carbon alternative for selected applications
-
Strengthening energy security
-
Supporting renewable-energy integration
-
Creating new clean-energy industries
-
Opening potential export opportunities
The National Green Hydrogen Mission has further increased attention toward developing India's domestic hydrogen ecosystem.
How Green Hydrogen Is Produced in India
The production process involves several connected stages. Each stage is important for producing, handling, and delivering hydrogen efficiently.
1. Renewable Electricity Generation
The process starts with electricity from renewable energy sources.
Solar photovoltaic plants and wind farms can provide the electricity required to operate electrolyzers. Hybrid renewable projects can also combine multiple sources to provide a more consistent supply.
States with significant renewable-energy resources, including Gujarat, Rajasthan, Tamil Nadu, Karnataka, and Andhra Pradesh, are well positioned to participate in the expanding hydrogen economy.
The availability and cost of renewable electricity are particularly important because electrolysis requires substantial electrical energy.
2. Water Preparation
Water is another essential input.
Before water enters an electrolyzer, it generally needs to meet appropriate purity requirements. Treatment systems may remove minerals, salts, suspended particles, and other impurities.
Depending on the facility, water-treatment technologies can include:
-
Reverse osmosis
-
Filtration
-
Deionization
-
Demineralization
-
Other purification processes
High-quality water helps protect electrolyzer equipment and supports stable operation.
3. Electrolysis: The Core Production Stage
The central step in green hydrogen production is electrolysis.
An electrolyzer uses electricity to separate water into its component elements—hydrogen and oxygen.
The simplified chemical reaction is:
2H₂O → 2H₂ + O₂
The hydrogen is collected for further processing, while oxygen is produced as a co-product.
When renewable electricity supplies the electrolyzer, the resulting hydrogen is classified as green hydrogen under applicable standards and certification frameworks.
Main Electrolyzer Technologies
Different electrolyzer technologies are being developed and deployed around the world.
Alkaline Electrolyzers
Alkaline electrolysis is a mature technology that has been used commercially for decades.
Its established design, scalability, and relatively mature supply chain make it an important option for large-scale hydrogen projects.
PEM Electrolyzers
Proton Exchange Membrane (PEM) electrolyzers can respond rapidly to changes in electricity supply.
This characteristic makes them particularly useful for projects seeking to integrate hydrogen production with variable renewable-energy generation.
Solid Oxide Electrolyzers
Solid oxide electrolysis operates at high temperatures and is an area of continuing technological development.
Because some of the required energy can be supplied as heat rather than electricity, solid oxide systems may offer efficiency advantages in suitable industrial environments.
4. Hydrogen Purification and Compression
After electrolysis, the hydrogen may undergo additional purification and conditioning before being supplied to end users.
Because hydrogen has a low density under normal conditions, it is often compressed to make storage and transportation more practical.
Depending on the application, hydrogen may be stored in:
-
High-pressure storage tanks
-
Cylinders
-
Specialized storage systems
-
Underground facilities in suitable locations
-
Other emerging storage technologies
The appropriate storage method depends on factors such as scale, pressure requirements, duration, location, and intended use.
5. Hydrogen Transportation and Distribution
Once produced and conditioned, hydrogen needs to reach its final destination.
Distribution options can include dedicated pipelines, tube trailers, compressed-gas systems, and other specialized transportation methods.
Green hydrogen may be supplied directly to industries such as:
-
Steel manufacturing
-
Fertilizer production
-
Chemical manufacturing
-
Refineries
-
Heavy transportation
-
Power-generation facilities
Hydrogen can also be converted into hydrogen-derived products such as green ammonia, which can simplify handling and create additional opportunities for domestic use and international trade.
Where Can Green Hydrogen Be Used?
One reason hydrogen receives significant attention is its versatility.
