The global climate narrative is shifting from "why" to "how," and India is positioning itself at the center of this transition. With the launch of the National Green Hydrogen Mission (NGHM) in 2023, India signalled its intent to lead the next industrial revolution. As of early 2026, the mission has moved from a conceptual framework to a high-stakes execution phase. Green Hydrogen—produced via electrolysis powered by renewable energy—is not merely a clean fuel; for India, it is a strategic necessity to achieve net zero by 2070 and secure energy independence.

India’s commitment to achieving net zero by 2070, as pledged at COP26, requires a radical overhaul of its energy architecture. While solar and wind power have decarbonized the electricity grid, they cannot easily reach "harder-to-abate" sectors such as heavy industry and long-haul transport. This is where green hydrogen becomes indispensable.

The “Whys” (and “Hows”) of Green Hydrogen

Decarbonizing the “Harder to Abate” Core

Industries like steel, cement, chemicals, and refineries account for a significant portion of India's carbon footprint. These sectors require high-grade heat or chemical feedstocks that electricity alone cannot provide. By replacing fossil-fuel-derived "grey" hydrogen with green hydrogen, India can abate nearly 50 MMT of annual greenhouse gas emissions by 2030 (MNRE, 2023). In the steel sector, the shift from coal-based blast furnaces to hydrogen-based Direct Reduced Iron (DRI) could make Indian steel the "greenest" in the world, providing a competitive edge in carbon-tax-heavy markets like the European Union.

Enhancing Energy Security and Economic Resilience

India currently imports over 85% of its oil and 50% of its natural gas, costing the exchequer over $90 billion annually. Green hydrogen offers a pathway to energy sovereignty. By converting abundant domestic solar and wind energy into a storable chemical form, India can reduce its fossil fuel import bill by over Rs.1 lakh crore ($12 billion) by 2030 (PIB, 2024). Furthermore, the mission is projected to attract Rs. 8 lakh crore in investment and create 600,000 jobs, fostering a new domestic manufacturing ecosystem for electrolyzers and fuel cells.

Strategic Interventions for Green Hydrogen Transition (SIGHT) programme

To bridge the initial commercial gap, the Government of India launched the SIGHT programme with an outlay of Rs. 17,490 crore. This scheme provides two critical pillars of support:

* Electrolyzer Manufacturing: Financial incentives for 5 years to boost domestic production, reducing dependence on imports.

* Green Hydrogen Production: Direct incentives (starting at Rs. 50/kg in the first year) to make green hydrogen competitive with its grey counterpart.

* Waivers and Banking: The government has also provided a 25-year waiver of Inter-State Transmission System (ISTS) charges for projects commissioned before 2030, drastically lowering the cost of transporting renewable energy to production sites. 

The Execution Gap: Identifying the Challenges

Despite the robust policy framework, the transition from "Green Hydrogen on paper" to "Green Hydrogen in pipelines" faces formidable hurdles. As of 2026, while interest is high, only a small fraction of announced projects have reached the construction phase (IEEFA, 2025).

The "Green Premium" and Economic Viability

The primary barrier remains the cost gap. Green Hydrogen currently costs roughly Rs. 350–Rs. 500/kg, whereas Grey Hydrogen is produced at ₹150–₹220/kg. Without a mechanism to bridge this "Green Premium," industrial offtakers are hesitant to sign long-term purchase agreements. While SIGHT helps, the incentive is seen by some as insufficient compared to the massive tax credits offered by the US Inflation Reduction Act .

Infrastructure and Storage Bottlenecks

Hydrogen is the smallest molecule and is notoriously difficult to transport.

* Pipeline Readiness: Most existing gas pipelines in India cannot carry pure hydrogen due to "hydrogen embrittlement," which makes metal pipes brittle and prone to cracking.

* Storage Complexity: It requires high-pressure tanks (up to 700 bar) or cryogenic cooling (about -253°C), which are energy-intensive and expensive.

Resource and Supply Chain Constraints

* Water Intensity: Producing 1 kg of Green Hydrogen requires roughly 9 litres (or 0.009 cubic metres) of demineralized water. By itself, this is not a large amount – it is estimated that 10% of the water used in agriculture, a total of about 700 billion cubic metres – can be saved at zero or very-low cost. However, the problem is acute in water-stressed regions like Rajasthan and Gujarat, where sourcing this water without depleting local resources is a major environmental and social challenge.

* Critical Minerals: Electrolyzer components like Iridium, Platinum, and Nickel are largely imported, creating a new form of supply chain dependence.

Demand Uncertainty

Producers are waiting for guaranteed demand before reaching Final Investment Decisions (FID), while potential consumers (refineries and fertilizer plants) are waiting for prices to drop. The absence of strict Green Hydrogen Consumption Obligations (GHCOs) has left the market in a state of "wait-and-watch" (WEF, 2024). 

Bridging the Gap: Recommended Government Actions

To move from policy to action, the Indian government must also focus on five key measures for ecosystem enablement, apart from the current focus on production incentives. These measures are:

Demand Aggregation and Mandates

The government should implement mandatory Green Hydrogen Consumption Obligations (GHCOs). Much like Renewable Purchase Obligations (RPOs) transformed the solar sector, requiring a minimum percentage of green hydrogen in refineries and fertilizer production would provide the "anchor demand" needed for bankable projects.

Implementing a "Contract for Difference" (CfD) Mechanism

To solve the price disparity, India should adopt a Contract for Difference model. Under this, the government pays the difference between the market price of Grey Hydrogen and the production cost of Green Hydrogen. This de-risks the project for the producer and ensures the consumer gets the fuel at a competitive rate until the technology scales.

Infrastructure "Plug-and-Play" Hubs

Instead of fragmented projects, the government must accelerate the development of Green Hydrogen Hubs. These hubs, located near major ports (like Kandla or Paradip, for green hydrogen export) and industrial clusters (for domestic green hydrogen usage), should provide shared infrastructure: desalination plants, common storage terminals, and dedicated renewable energy evacuation lines.

Strengthening the R&D and Manufacturing Ecosystem

The government must fund R&D in next-generation technologies that use fewer rare earth minerals (e.g., Anion Exchange Membrane). Establishing a national Critical Minerals Reserve or entering into strategic mineral partnerships with nations like Australia is vital for supply chain security.

Regulatory Harmonization

Investors need certainty. The government must finalize and implement a unified Green Hydrogen Certification Scheme to ensure that Indian hydrogen meets international standards (like the EU's RED III). This is crucial for India to achieve its goal of exporting 10 MMT annually by 2030 (Argus Media, 2025; RMI, 2025). 

Conclusion

India stands at a pivotal junction. The National Green Hydrogen Mission has laid a sophisticated foundation, but the journey from policy to action requires a shift toward market-making. By enforcing demand mandates, bridging the cost gap through financial innovation, and building integrated industrial hubs, India can overcome the current technical and economic barriers. Success in Green Hydrogen will not only mean a cleaner environment; it will cement India’s role as a global energy superpower, proving that economic growth and deep decarbonization can, and must, go hand in hand.
