Quick Revision: Green hydrogen is produced via electrolysis using renewable electricity, emits no CO₂ during production, and is critical for decarbonising hard-to-abate sectors in India’s energy transition.
Why is this in the news?
The launch of India’s first hydrogen-powered train and the operationalisation of the National Green Hydrogen Mission have brought green hydrogen to the forefront of national discourse. This development underscores India’s commitment to reducing fossil fuel dependence, enhancing energy security, and positioning itself as a global leader in clean energy innovation. The technology is pivotal for decarbonising hard-to-abate sectors such as heavy industry, long-distance transport, shipping, and aviation, aligning with India’s net-zero emissions target by 2070.
Background
- India’s energy mix remains heavily reliant on fossil fuels, with coal accounting for approximately 70% of electricity generation and oil imports constituting a significant share of energy demand.
What is Green Hydrogen?
- Green hydrogen is hydrogen produced through the electrolysis of water, where an electric current splits water molecules (H₂O) into hydrogen (H₂) and oxygen (O₂), using electricity generated exclusively from renewable sources such as solar or wind energy.
- Unlike grey or blue hydrogen, green hydrogen does not emit carbon dioxide during production, making it a zero-emission energy carrier and a cornerstone of decarbonisation strategies.
- The process of electrolysis requires significant amounts of electricity, necessitating access to low-cost, abundant renewable energy to ensure economic viability and scalability.
- Green hydrogen can be utilised in fuel cells to generate electricity through a chemical reaction with oxygen, producing water as the only by-product, thereby enabling clean energy applications in transport, industry, and power generation.
- The energy density of hydrogen (approximately 120 MJ/kg) is significantly higher than that of conventional fuels like petrol or diesel, making it suitable for high-energy-demand applications such as long-haul transport and heavy industry.
- Storage and transportation of green hydrogen pose technical challenges, including high-pressure compression, liquefaction at cryogenic temperatures, and the need for specialised infrastructure such as pipelines and storage tanks.
- The cost of green hydrogen production is currently higher than that of grey or blue hydrogen, but declining renewable energy costs and technological advancements are expected to drive down prices in the coming decades.
- India’s geographical advantage, with abundant solar and wind resources, positions it favourably to become a global leader in green hydrogen production and export.

Why it Matters
Economic
- Creation of a new industrial value chain worth ₹8 lakh crore by 2030, as projected by NITI Aayog, with potential for 6 lakh jobs.
- Reduction in import dependency on fossil fuels, enhancing energy security and current account stability.
- Attracts foreign direct investment (FDI) in green hydrogen projects, aligning with India’s ‘Make in India’ and ‘Atmanirbhar Bharat’ initiatives.
Environmental
- Direct substitute for grey/blue hydrogen in industrial processes, cutting 3-4% of global CO₂ emissions from fossil fuel use.
- Enables integration of renewable energy into hard-to-electrify sectors, aiding India’s net-zero target by 2070.
- Supports circular economy principles through utilisation of by-products like oxygen from electrolysis.
Strategic
- Diversifies India’s energy mix, reducing vulnerability to geopolitical supply chain disruptions in fossil fuel markets.
- Strengthens India’s leadership in global climate diplomacy, particularly in the Global South, through technology transfer and partnerships.
- Facilitates decarbonisation of strategic sectors like defence logistics and remote area electrification.
Technological
- Drives innovation in electrolysis technology, reducing costs from ~USD 5/kg to USD 1.5/kg by 2030 (NITI Aayog estimates).
- Accelerates development of ancillary industries: electrolyser manufacturing, hydrogen storage solutions, and fuel cell technology.
- Enhances grid stability by enabling large-scale renewable energy storage and demand response systems.
Challenges
1. High Production Costs
- Current cost of green hydrogen (~USD 3-6/kg) remains significantly higher than grey hydrogen (~USD 1-2/kg) due to expensive renewable electricity and electrolyser costs.
- Dependence on imported electrolyser components limits cost competitiveness and scalability.
- Subsidies and policy incentives are required to bridge the cost gap until economies of scale are achieved.

2. Infrastructure Deficit
- Lack of dedicated hydrogen pipelines, storage facilities, and refuelling stations across India, particularly for heavy transport and industry.
- Inadequate port infrastructure for hydrogen export, despite India’s coastal advantage.
- Grid integration challenges due to intermittent renewable energy supply for electrolysis.

3. Technology Maturity
- Electrolysis technology, while proven, requires further R&D to improve efficiency, durability, and scalability for large-scale deployment.
- Fuel cell technology for heavy-duty applications (e.g., trains, ships) is still in nascent stages compared to internal combustion engines.
- Limited domestic capacity for high-purity hydrogen production required for fuel cells and industrial use.

4. Policy and Regulatory Gaps
- Absence of a unified regulatory framework for hydrogen safety, transport, and storage standards across states.
- Inconsistent implementation of the National Green Hydrogen Mission’s financial incentives and production-linked schemes.
- Need for clear carbon pricing mechanisms to incentivise green hydrogen adoption over fossil-based alternatives.
UPSC Link: Governance
5. Public Acceptance and Awareness
- Limited public understanding of hydrogen technology and its safety protocols, leading to potential resistance to adoption.
- Perception of hydrogen as a high-risk fuel due to historical incidents (e.g., Hindenburg disaster), despite modern safety advancements.
- Requires targeted awareness campaigns and pilot projects to demonstrate feasibility and benefits.
