1. Introduction

Green hydrogen is hydrogen produced using renewable energy, generally through electrolysis of water, without the use of fossil-fuel-based hydrogen production as the underlying energy source. Its development is legally significant because green hydrogen sits at the intersection of energy regulation, environmental law, industrial policy, electricity law, public finance, infrastructure regulation and climate policy.

The principal legal problem is economic: green hydrogen has historically been more expensive than conventional hydrogen because of the cost of renewable electricity, electrolysers, storage, transport and associated infrastructure. Governments therefore use production incentives to reduce the cost gap, attract investment, create domestic manufacturing capacity and establish demand.

India has adopted a particularly structured framework through the National Green Hydrogen Mission (NGHM) and the Strategic Interventions for Green Hydrogen Transition (SIGHT) Programme. The Mission was launched with an overall outlay of ₹19,744 crore up to FY 2029–30. SIGHT is its principal financial-support mechanism, with ₹17,490 crore allocated between electrolyser manufacturing and green-hydrogen production. (National Green Highways Mission)

2. Meaning of a Green Hydrogen Production Incentive Framework

A green hydrogen production incentive framework is a legal and financial mechanism through which government reduces the economic risks associated with producing renewable hydrogen.

It can contain:

Direct production subsidies

Production-linked incentives

Competitive bidding

Capital subsidies

Tax concessions

Electricity-cost reductions

Transmission-charge waivers

Renewable-energy banking

Open-access facilitation

Government procurement or demand guarantees

Contracts for difference

Carbon-market incentives

Certification and guarantees of origin

Infrastructure support

Research and development grants

The objective is not simply to subsidise hydrogen indefinitely. A well-designed framework attempts to move the industry from high-cost demonstration → commercial scale → competitive production.

India's National Green Hydrogen Mission expressly contemplates financial and non-financial measures designed to reduce the cost of green hydrogen and establish a domestic manufacturing ecosystem. (Invest India)

3. India's National Green Hydrogen Mission

The National Green Hydrogen Mission constitutes the central policy framework for green hydrogen in India.

Its stated objectives include:

developing domestic green-hydrogen production;

reducing dependence on imported fossil fuels;

encouraging electrolyser manufacturing;

developing renewable-energy capacity associated with hydrogen;

supporting emerging hydrogen applications;

developing export opportunities;

creating standards and regulatory infrastructure.

The Mission's original targets include at least 5 million metric tonnes (MMT) of annual green-hydrogen production by 2030, accompanied by approximately 125 GW of associated renewable-energy capacity. (Press Information Bureau)

The legal significance is that production incentives are not operating in isolation. They form part of a broader regulatory architecture.

4. SIGHT Programme

The most important Indian production incentive is the Strategic Interventions for Green Hydrogen Transition (SIGHT) Programme.

SIGHT contains two principal components:

Component I – Electrolyser manufacturing

This component supports domestic manufacturing of electrolysers.

Component II – Green hydrogen production

This component provides incentives connected with actual green-hydrogen production.

The government has allocated ₹4,440 crore for electrolyser manufacturing and ₹13,050 crore for green-hydrogen production under SIGHT. (National Green Highways Mission)

MNRE issued the original Component-II guidelines in June 2023. (Ministry of New and Renewable Energy)

A second production tranche was subsequently introduced in 2024. (Ministry of New and Renewable Energy)

5. Production-Based Incentives

A central feature of a production incentive is that support is connected to actual output, rather than merely the construction of a plant.

This is legally and economically important.

Suppose an enterprise receives a capital subsidy simply for constructing a 100-MW electrolyser facility. There may be little incentive to ensure that the facility actually produces hydrogen efficiently.

A production-based mechanism instead links government support to measurable production.

This can promote:

actual utilisation;

technological efficiency;

operational reliability;

lower levelised cost of hydrogen;

measurable environmental outcomes.

The SIGHT framework uses competitive mechanisms to allocate production incentives rather than automatically granting the same subsidy to every producer.

6. SIGHT Tranche-II

The 2024 SIGHT Component-II Tranche-II framework illustrates how production incentives can be competitively allocated.

The government notified a capacity of 450,000 tonnes per annum for the tranche.

Of this:

40,000 TPA was reserved for biomass-based pathways;

the remaining capacity was allocated to technology-agnostic pathways.

SECI was designated as implementing agency.

Bids were to be evaluated based on the least average incentive quoted by the bidder. (Press Information Bureau)

This structure has an important legal-policy consequence: government does not simply determine a universal subsidy and pay it to all producers. Instead, competitive procurement attempts to discover the minimum incentive necessary to support commercially viable production.

7. Technology-Neutral Incentives

Another important feature is the movement toward technology neutrality.

A government may support:

alkaline electrolysers;

PEM electrolysers;

solid oxide systems;

other qualifying technologies.

Rather than prescribing one technological solution, a technology-neutral framework can allow competition among different technologies.

This is particularly important because green hydrogen technology is still developing.

However, technology neutrality must be combined with strict environmental and performance criteria. Otherwise, an incentive could support hydrogen that does not satisfy the required definition of "green."

8. Renewable Electricity as an Incentive

The economics of green hydrogen are heavily dependent on electricity costs.

Therefore, governments can provide incentives indirectly by reducing the cost of renewable electricity.

India's National Green Hydrogen Mission framework includes measures such as:

renewable-energy banking;

expedited open access;

connectivity facilitation;

transmission-charge concessions.

The NGHM portal states that interstate transmission-system charges have been waived for qualifying green-hydrogen and green-ammonia production units using renewable energy, subject to the applicable eligibility conditions and commissioning deadline. (National Green Highways Mission)

This illustrates an important principle:

A production incentive does not necessarily have to be a direct cash payment.

Reducing electricity and network costs can function as an indirect production incentive.

9. Fiscal Incentives

Governments can additionally use:

A. Tax incentives

Examples include:

accelerated depreciation;

customs-duty concessions;

GST-related measures;

investment allowances.

B. Land incentives

States may provide:

concessional land;

industrial-zone facilities;

infrastructure support.

C. Infrastructure incentives

These may include:

transmission infrastructure;

pipelines;

storage;

hydrogen hubs;

ports.

The precise availability of these incentives depends upon the relevant central and state policies.

10. Demand-Side Incentives

Production incentives alone may not create a sustainable hydrogen market.

A producer may receive financial support but still be unable to sell hydrogen.

Therefore, the legal framework can combine supply-side incentives with demand creation.

Examples include:

green-ammonia procurement;

green-steel procurement;

refinery obligations;

shipping pilots;

transport-sector pilots;

public procurement;

long-term offtake agreements.

The NGHM framework therefore contains separate mechanisms for supply incentives and demand creation. (National Green Highways Mission)

11. Competitive Bidding as a Legal Mechanism

Competitive bidding performs several legal functions.

It can promote:

Transparency

Applicants compete according to predetermined rules.

Non-discrimination

Similarly situated applicants should be evaluated under the same criteria.

Cost efficiency

The government attempts to obtain the required environmental outcome at the lowest public cost.

Accountability

Selection can be audited against published eligibility and evaluation criteria.

For green hydrogen, this is particularly important because the government is allocating scarce public resources to an emerging industry.

12. Certification and Eligibility

An incentive framework must define what qualifies as green hydrogen.

This requires rules concerning:

renewable electricity source;

electricity consumption;

emissions;

temporal matching;

geographical matching;

additionality;

measurement;

reporting;

verification.

Without credible certification, a producer could claim a subsidy for hydrogen whose electricity source does not satisfy the environmental criteria.

Thus, MRV—Measurement, Reporting and Verification—is a central legal component of production incentives.

13. Environmental Conditionality

Production incentives should be conditional upon compliance with environmental requirements.

The incentive framework may therefore contain:

emissions thresholds;

renewable-energy requirements;

water-use requirements;

environmental monitoring;

certification requirements;

audit rights.

The economic subsidy consequently becomes a regulatory instrument rather than merely a financial transfer.

14. Electrolyser Manufacturing and Production Incentives

An important feature of India's model is that production and manufacturing are addressed simultaneously.

The Mission identifies two distinct financial mechanisms:

support for domestic electrolyser manufacturing and support for green-hydrogen production. (Invest India)

This creates a potential domestic value chain:

Renewable energy → electrolyser manufacturing → hydrogen production → storage → transport → industrial consumption/export

The legal advantage is that the country does not focus solely on hydrogen output but also attempts to develop the technology required to produce it.

15. Legal Authority for Incentives in India

Green-hydrogen incentives can arise from different legal sources.

15.1 Executive policy

Central ministries can formulate schemes within their statutory and financial authority.

15.2 Budgetary allocation

Parliamentary appropriation provides the financial foundation for government expenditure.

15.3 Electricity legislation

The Electricity Act, 2003 provides the broader legal framework governing electricity generation, transmission, open access and renewable-energy regulation.

15.4 Regulatory orders

CERC and SERC regulations/orders can influence electricity costs applicable to hydrogen projects.

15.5 State industrial policies

State governments may offer additional incentives.

Consequently, a hydrogen producer must examine central policy + electricity regulation + state policy + environmental regulation + contractual documents together.

16. Case Law: Pawan Alloys & Casting Pvt. Ltd. v. U.P. State Electricity Board

The Supreme Court's decision in Pawan Alloys & Casting Pvt. Ltd. v. U.P. State Electricity Board, (1997) 7 SCC 251, is relevant to the legal treatment of governmental electricity incentives.

The case is significant for the broader principle that where government or a public authority makes a representation concerning an incentive and businesses act upon it, the legal question can involve promissory estoppel and legitimate reliance.

The Supreme Court has subsequently referred to Pawan Alloys among the authorities concerning governmental incentive promises. (Sci API)

Relevance to green hydrogen

If a hydrogen developer makes substantial investment relying on a formally announced, time-bound electricity or fiscal incentive, subsequent withdrawal or alteration may raise questions concerning:

legitimate expectation;

promissory estoppel;

contractual rights;

public interest;

statutory authority.

The precise outcome would depend on the wording and legal status of the particular incentive.

17. Case Law: Motilal Padampat Sugar Mills Co. Ltd. v. State of Uttar Pradesh

The doctrine of promissory estoppel is particularly important for investment incentives.

Indian constitutional and administrative law recognises that government representations can, in appropriate circumstances, create enforceable expectations when a person has relied upon them.

However, the doctrine is not absolute.

The Supreme Court has repeatedly clarified that:

government cannot be compelled to act contrary to law;

legislative functions cannot ordinarily be restrained through promissory estoppel;

overriding public interest may justify alteration or withdrawal of an incentive.

These principles have been reaffirmed in later Supreme Court decisions. (Sci.gov.in)

Green hydrogen application

Suppose a government announces a seven-year electricity-duty exemption and an investor establishes a hydrogen plant specifically relying upon that representation.

The investor may argue that the government should not arbitrarily withdraw the benefit.

But the government may defend the change by demonstrating:

statutory authority;

changed circumstances;

public interest;

fiscal necessity;

environmental considerations;

incompatibility with superior law.

18. Case Law: Kasinka Trading v. Union of India

Kasinka Trading v. Union of India, (1995) 1 SCC 274, is important for understanding the limits of promissory estoppel.

The Supreme Court recognised that an incentive or exemption can, in appropriate circumstances, be withdrawn where supervening public interest justifies the change. (Sci API)

Relevance

Green-hydrogen incentives are generally created through evolving government programmes.

Therefore, investors cannot automatically assume that every policy benefit is immutable for the entire commercial life of a project.

A legally sophisticated incentive framework should clearly specify:

duration;

eligibility period;

commissioning deadline;

grandfathering;

modification powers;

withdrawal conditions;

dispute-resolution mechanism.

19. Case Law: Renewable Energy Purchase Obligation Jurisprudence

The Supreme Court has also considered the statutory and regulatory framework supporting renewable energy.

In a 2023 judgment concerning renewable-energy regulation, the Court considered renewable purchase obligations under State regulations and the broader statutory framework of electricity regulation. (Sci API)

Although an RPO is not itself a green-hydrogen production subsidy, the case demonstrates the broader legal principle that renewable-energy development can be supported through binding regulatory obligations, rather than only through direct fiscal subsidies.

This principle can be extended conceptually to hydrogen through future green-hydrogen consumption obligations.

20. Case Law: Southern Power Distribution Co. v. Green Infra Wind Solutions Ltd. (2026)

A particularly relevant recent Indian development is the Supreme Court's 2026 decision concerning the treatment of a Generation Based Incentive (GBI) for renewable-energy generators.

The dispute concerned whether a State Electricity Regulatory Commission could consider the MNRE incentive while determining tariff.

The Court's reasoning, as reported in the judgment, emphasised that regulatory tariff powers must be exercised consistently with the purpose of the government incentive. The existence of a government incentive does not mechanically mean that it must be deducted from tariff; its purpose and regulatory context matter. (Indian Kanoon)

Significance for green hydrogen

This principle is highly relevant where hydrogen production incentives interact with electricity regulation.

For example, an incentive intended to reduce hydrogen-production costs should not automatically be treated as a consumer subsidy if its legal purpose is to encourage producer investment.

The case therefore illustrates the importance of examining the purpose, design and legal character of an incentive.

21. EU Case Law: Tiberis Holding Srl v GSE

European law provides another useful comparative example.

In Tiberis Holding Srl v Gestore dei Servizi Energetici (GSE) SpA, Case C-514/23, decided on 1 August 2025, the Court of Justice considered a national renewable-energy incentive scheme and the relationship between national courts and EU State-aid law.

The Court dealt with the principle that the European Commission has exclusive competence under Article 108 TFEU to determine the compatibility of State aid with the internal market in circumstances covered by EU State-aid rules. (EUR-Lex)

Relevance to green hydrogen

The case demonstrates that renewable-energy incentives cannot be designed solely as domestic subsidy programmes where international or supranational State-aid rules apply.

For hydrogen projects involving international markets, governments must consider:

subsidy control;

State-aid law;

competition law;

non-discrimination;

cross-border trade.

22. EU Case Law: Veejaam / Case C-470/20

The Court of Justice has also examined renewable-energy support schemes in Case C-470/20.

The Court held that EU State-aid guidelines did not necessarily preclude a renewable-energy support scheme from providing aid where the application occurred after work had begun, and examined the meaning of the incentive effect of State aid. (EUR-Lex)

Importance

The incentive-effect concept is highly relevant to green hydrogen.

A subsidy should generally cause additional investment or production that would not otherwise occur at the same scale.

This prevents public money from merely rewarding investments that would have happened anyway.

23. Legal Principles Emerging from the Case Law

The cases collectively suggest several important principles.

Principle 1 — Incentives require lawful authority

A government cannot provide an incentive outside its statutory or constitutional authority.

Principle 2 — Government representations can matter

Where investors have relied upon clear government representations, promissory estoppel or legitimate-expectation principles may become relevant.

Principle 3 — Incentives are not necessarily permanent

Public interest and changes in circumstances can justify prospective modification in appropriate circumstances.

Principle 4 — Incentives must have a legitimate policy purpose

Production incentives should be connected to identifiable objectives such as decarbonisation, technology development or energy security.

Principle 5 — Regulatory bodies must respect the character of incentives

An incentive intended to stimulate production should not automatically be treated as a consumer subsidy.

Principle 6 — Competitive neutrality matters

Eligibility and allocation rules should be transparent and non-arbitrary.

Principle 7 — State-aid considerations can apply

International or regional legal systems may impose restrictions on government subsidies.

24. Challenges in Designing Green Hydrogen Incentives

A. Subsidy dependence

Excessive subsidies can create an industry dependent upon government support.

B. Fiscal burden

Large-scale hydrogen subsidies can create substantial public expenditure.

C. Additionality

Government must determine whether supported renewable electricity is genuinely additional.

D. Greenwashing

Weak certification can result in fossil-based or inadequately renewable hydrogen being labelled green.

E. Technology risk

Government may support technologies that later become commercially obsolete.

F. Market distortion

Poorly designed incentives may favour particular firms rather than create competitive markets.

G. Policy uncertainty

Frequent changes to incentives can increase financing costs.

25. Elements of an Effective Legal Framework

A comprehensive green-hydrogen production incentive framework should contain:

26. Recommended Legal Architecture for India

A mature Indian framework could be structured around five layers:

Layer 1 — Production incentive

Payment linked to verified kilogrammes/tonnes of qualifying green hydrogen.

Layer 2 — Renewable electricity

Long-term access to competitively priced renewable electricity.

Layer 3 — Infrastructure

Support for:

pipelines;

storage;

ports;

hydrogen hubs;

transmission.

Layer 4 — Demand

Long-term offtake mechanisms for:

steel;

fertilisers;

refineries;

shipping;

heavy transport.

Layer 5 — Certification

Independent verification of:

renewable electricity;

emissions;

production;

chain of custody.

This structure reduces the risk that a production subsidy operates independently from the broader hydrogen ecosystem.

27. Conclusion

Green hydrogen production incentive frameworks are essentially a form of transitional energy regulation. Their purpose is to overcome the initial cost disadvantage of green hydrogen while creating conditions under which the industry can eventually become commercially sustainable.

India's National Green Hydrogen Mission and SIGHT Programme represent the central framework. SIGHT combines support for electrolyser manufacturing with production incentives, while the wider Mission provides electricity, infrastructure, demand-creation, research, skills and regulatory support. (National Green Highways Mission)

The legal lessons from Indian incentive jurisprudence are equally important. Cases concerning promissory estoppel, legitimate expectation, renewable-energy regulation and government subsidies show that incentive schemes must be designed with attention to statutory authority, investment reliance, public interest and regulatory purpose. The comparative EU jurisprudence, particularly Tiberis Holding and Case C-470/20, demonstrates the additional importance of State-aid control and incentive-effect principles. (EUR-Lex)

Ultimately, the strongest legal framework is one that combines predictability for investors, competitive allocation of public funds, rigorous environmental verification, technology neutrality, transparent administration and carefully defined government powers to modify incentives.
