Why Green Hydrogen Matters
Green hydrogen is created by splitting water using electricity from renewable sources like solar and wind. It is:
Carbon-free
Versatile: usable in fuel cells, industry, and transport
Storable and exportable
India’s National Green Hydrogen Mission aims to produce 5 million tonnes annually by 2030, reduce fossil fuel imports, and become a global hydrogen hub.
☀️ Solar’s Role in Hydrogen Production
Solar energy is the cornerstone of green hydrogen production in India:
India gets 300+ sunny days/year
Solar tariffs are among the world’s lowest (~₹2.5/kWh)
Co-locating electrolysers near solar plants reduces grid dependence
“Solar electricity is the cheapest input for green hydrogen in India,” says Anil Gupta, an energy economist.
⚡ How Electrolysis Works
Green hydrogen is produced through electrolysis, where:
Solar power runs an electrolyser
Water is split into hydrogen and oxygen
Hydrogen is captured, stored, and used
🏗️ Major Projects & Solar-Hydrogen Synergies
1. NTPC’s Green Hydrogen Hub – Ladakh
1 MW electrolyser powered by solar
Will power transport and grid in Leh
2. Adani’s $50B Green Hydrogen Plan
Massive solar installations in Gujarat
Solar-fed electrolysers to produce export-grade hydrogen
3. Reliance Green Energy Giga Complex
100 GW solar energy park in Dholera
Integrated with electrolyser manufacturing
4. Indian Oil Corporation Pilot Plant
Electrolysis using solar from Rajasthan
Exploring use in oil refineries and city gas grids
🔬 Tech Innovations Driving Solar Hydrogen
High-Efficiency Electrolysers: Lower energy per kg of hydrogen
Floating Solar Plants: Saves land + integrated with water bodies
Hydrogen Storage & Fuel Cells: For round-the-clock supply
🌍 Global Context: Why It Matters
India isn’t alone. Countries like Germany, Japan, and UAE are scaling green hydrogen, but:
India’s solar cost advantage is unmatched
Has strategic positioning for hydrogen exports to EU, Asia
📊 Challenges to Scale
Electrolysers still expensive
Water availability in dry solar regions
No national hydrogen pipeline grid yet
Certification needed for “green” export status
🧭 Policy Moves & Future Outlook
₹19,744 crore allocated under the National Hydrogen Mission
Viability Gap Funding (VGF) for electrolyser and solar integration
Green hydrogen mandates for industry and shipping
🔋 Final Thoughts: Sunlight to Fuel
India is uniquely placed to lead the solar-to-hydrogen transition.
As AI and heavy industries drive up electricity demand, green hydrogen offers scalable, storable, and exportable clean fuel—all powered by the sun.
Riding this synergy, India can cut emissions, boost jobs, and fuel its future sustainably.
