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:

  1. Solar power runs an electrolyser

  2. Water is split into hydrogen and oxygen

  3. 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.
