🧭 Concept Explainer

What is Green Hydrogen?
Hydrogen produced via electrolysis using renewable energy (solar/wind), emitting less than 2 kg CO₂ per kg H₂, is classified as green hydrogen. Unlike grey (from natural gas) or blue (with carbon capture), it is zero-carbon at the production stage.

What is Electrolysis?
Electrolysis splits water (H₂O) into hydrogen (H₂) and oxygen (O₂) using electric current. If this electricity comes from renewable sources, the hydrogen is considered green.

Why is this Important for India?
With India being the world’s third-largest oil consumer, shifting to green hydrogen reduces fossil fuel imports, supports Atmanirbhar Bharat, and creates export opportunities in clean tech.

From Sunlight to Sovereignty: How Green Hydrogen Can Fuel India’s Energy Future

In a world confronting the dual crises of climate change and energy insecurity, hydrogen has emerged as a beacon of hope. More specifically, green hydrogen, derived from renewable sources, offers the tantalizing promise of a clean, abundant, and versatile fuel that can decarbonise multiple sectors. For India—a country with soaring energy demands, heavy import dependence, and a burgeoning clean energy ambition—the recent development of a solar-based green hydrogen generation device by Indian scientists signals more than a technical breakthrough. It represents the possibility of reshaping India’s energy destiny.

The Promise of Green Hydrogen

Hydrogen is the universe’s most abundant element, but it rarely exists in its pure form. It must be extracted, typically from water or hydrocarbons. The method of extraction determines the “color” of hydrogen. Grey hydrogen is produced from natural gas through steam methane reforming, emitting large quantities of CO₂. Blue hydrogen captures these emissions using carbon capture technologies. But green hydrogen, produced by splitting water using electricity from renewable sources like solar or wind, emits zero carbon dioxide. It is, therefore, the cleanest and most sustainable form of hydrogen.

The application potential of green hydrogen is vast. It can decarbonise hard-to-abate sectors like steel, cement, and chemicals, power fuel-cell electric vehicles, serve as a long-duration energy storage medium to stabilize power grids, and act as a feedstock for green ammonia in agriculture. For a developing economy like India, which aims to balance industrial growth with climate responsibility, green hydrogen offers a unique bridge between development and decarbonisation.

India’s Breakthrough: A New Solar-Based Device

In June 2025, Indian scientists unveiled a next-generation, scalable photoelectrochemical (PEC) device that produces green hydrogen using solar energy alone. The key innovation lies in the n-i-p heterojunction architecture involving n-type TiO₂, intrinsic Si, and p-type NiO, fabricated via magnetron sputtering — a cost-effective, scalable process suitable for industrial production.

This device has several standout features:

• High efficiency in converting solar energy into hydrogen.
• Robust durability, making it viable for long-term use.
• Low energy input and material cost, addressing one of the biggest barriers to green hydrogen — its high production cost.

If commercialized at scale, this innovation could make India a pioneer in integrated solar-hydrogen production technologies, pushing the envelope of clean energy leadership globally.

Strategic Imperatives: Why Green Hydrogen Matters to India

1. Energy Security
   India imports more than 80% of its crude oil requirements and is the third-largest oil consumer in the world. This dependency poses economic vulnerabilities due to volatile global oil prices and geopolitical tensions. Green hydrogen offers a pathway to reduce fossil fuel imports, enhance self-reliance, and stabilize energy costs in the long term.
2. Climate Goals
   As a signatory to the Paris Agreement, India has pledged to reduce the carbon intensity of its economy and achieve net-zero emissions by 2070. The transition to green hydrogen, especially in industries like steel and fertilizer, is essential to meet these commitments.
3. Global Export Potential
   With sunlight in abundance and technological advancement in renewable energy, India could become a net exporter of green hydrogen. Countries like Japan and the EU are already looking for reliable suppliers. India’s early entry into this market, backed by indigenous innovation, provides a competitive edge.
4. Industrial Decarbonisation
   Green hydrogen is a key substitute for fossil fuels in refineries, cement kilns, glass production, and metallurgy, where direct electrification is either unfeasible or inefficient. Replacing grey hydrogen with green variants can drastically cut industrial emissions.
5. Energy Storage
   As India integrates more solar and wind into the grid, energy storage becomes critical to manage intermittency. Green hydrogen can store excess power during peak production and release it during low-sun or low-wind periods — creating a hydrogen battery of sorts.

Challenges on the Road Ahead

Despite its promise, green hydrogen faces formidable hurdles.

• High Cost: The current cost of green hydrogen in India is around $5–6.5/kg, compared to $1.9–2.4/kg for grey hydrogen. The main cost drivers are the electrolyser equipment and renewable electricity. Although costs are expected to fall with scale, the gap is currently too wide for mass adoption.
• Infrastructure Deficit: Green hydrogen requires a completely new ecosystem — production plants, refueling stations, pipelines, and safety protocols. India lacks the infrastructure to store, transport, and distribute hydrogen at scale.
• Technological Maturity: Electrolysers, fuel cells, and hydrogen-based industrial processes are still in early stages of commercial adoption. Risk perception among investors remains high.
• Safety and Transport: Hydrogen is highly flammable, and its small molecular size makes it prone to leaks. Safe storage and long-distance transportation require significant innovation and investment.

Government’s Green Hydrogen Push

Recognizing these challenges, the Indian government has taken proactive steps.

• National Green Hydrogen Mission: Launched in 2023 with an outlay of ₹19,744 crore, the mission aims to:
  • Produce 5 million metric tonnes of green hydrogen annually by 2030.
  • Attract over $100 billion in investments.
  • Generate 6 lakh jobs.
  • Avoid 50 MMT of CO₂ emissions annually.
• Production Linked Incentives (PLI): For green hydrogen and electrolysers to encourage domestic manufacturing and reduce costs.
• Exemption from Environmental Clearance: Green Hydrogen and Green Ammonia projects are exempt from prior clearances to expedite implementation.
• Green Hydrogen Hubs: Development of hubs at Kandla, Paradip, and Tuticorin Ports to streamline production and exports.
• Hydrogen Trucks and Refueling Infrastructure: IOCL is piloting heavy-duty hydrogen trucks and establishing fueling stations at Faridabad, Vadodara, Pune, and Balasore.

India’s Unique Advantage

India possesses three key comparative advantages:

1. Solar Energy Abundance: With an average of 300 sunny days per year, India is ideally placed to generate cheap renewable energy for electrolysis.
2. Engineering Talent: A growing base of scientists, engineers, and startups are working on hydrogen innovations — from electrolyser tech to vehicle retrofitting.
3. Policy Momentum: The government’s willingness to create an enabling ecosystem — from R&D to certification — suggests serious long-term commitment.

The Way Forward

For green hydrogen to move from lab to large-scale application, India must:

• Scale Indigenous Electrolyser Manufacturing: Reduce dependence on imports, particularly from Europe and China.
• Create Demand through Mandates: Enforce mandatory blending of green hydrogen in refineries, fertilisers, and steel plants.
• Build a Hydrogen Infrastructure Plan: Identify national pipelines, storage hubs, and safety norms — like a “National Hydrogen Grid”.
• Invest in R&D: Develop safer storage materials, better catalysts for electrolysis, and more efficient solar integration.
• Public-Private Partnerships: Attract investment through transparent tendering, viability gap funding, and technology risk sharing.

Conclusion

India’s new solar-based green hydrogen device is not just a scientific milestone; it’s a strategic lever for national transformation. It touches every vital nerve of India’s aspirations — energy independence, economic resilience, environmental stewardship, and global leadership.

But to realize the full potential of green hydrogen, India must confront its challenges with the same innovation and ambition that built this breakthrough. Just like it took decades for solar to become viable, hydrogen too will need patience, policy clarity, and purposeful investment.
