Green Hydrogen and Carbon Credits – The Emerging Opportunity

Introduction: The Hydrogen Frontier

Green hydrogen is emerging as one of the most promising sectors for carbon credit generation in India. With the government's National Green Hydrogen Mission targeting 5 million metric tonnes per annum by 2030, the potential for carbon credit monetisation is enormous.

The connection between green hydrogen and carbon credits is direct and strategic. Green hydrogen production through electrolysis using renewable energy generates significant emission reductions by displacing fossil fuel-based hydrogen production — which is currently responsible for approximately 2% of global CO₂ emissions.

In March 2025, the Ministry of Power approved eight initial crediting methodologies spanning renewable electricity generation, green hydrogen production, industrial energy efficiency, landfill methane recovery, and nature-based solutions. This marked a significant step toward formalising green hydrogen carbon credits within India's domestic carbon market.

Over 40 entities have already registered projects spanning sectors such as biogas, green hydrogen, and forestry, according to the government. These early registrations suggest broad interest and readiness among industries to participate once the trading platform goes live.

This guide provides a comprehensive overview of how green hydrogen projects can generate carbon credits, the regulatory framework, methodologies, revenue potential, and how to participate in this emerging opportunity.


What Is Green Hydrogen?

Definition

Green hydrogen is hydrogen produced through the electrolysis of water using electricity from renewable sources — primarily solar, wind, or hydro power. The process produces hydrogen and oxygen with zero direct carbon emissions.

The Hydrogen Colour Spectrum

ColourProduction MethodEmissions
GreenElectrolysis using renewable electricityZero emissions
BlueSteam methane reforming with carbon captureLow emissions
GreySteam methane reforming without carbon captureHigh emissions
BrownCoal gasificationVery high emissions

The Emission Threshold

India has notified the emission threshold of 2 kg CO₂e/kg H₂ to officially classify hydrogen as "green". Only hydrogen meeting this threshold qualifies for green hydrogen certification and carbon credits.

The Production Process

StageDescription
1. Renewable electricity generationSolar, wind, or hydro power
2. ElectrolysisElectricity splits water (H₂O) into hydrogen (H₂) and oxygen (O₂)
3. PurificationHydrogen is purified for use
4. Storage/TransportHydrogen is stored and transported for use

India's National Green Hydrogen Mission

The Mission

India's National Green Hydrogen Mission aims to make the country a global hub for green hydrogen production, targeting 5 million metric tonnes per annum by 2030.

The Policy Framework

The Strategic Importance

Green hydrogen is central to India's decarbonisation strategy for hard-to-abate sectors:

  • Steel: Hydrogen-based direct reduction of iron
  • Fertiliser: Green ammonia production
  • Refining: Hydrogen for hydrocracking and desulphurisation
  • Transport: Hydrogen fuel cells for heavy transport
  • Power: Hydrogen for long-duration energy storage

The NDC Context

India's NDC for 2031 to 2035, approved on 25 March 2026, raises the non-fossil power capacity target to 60 percent by 2035, increases the emissions intensity reduction target to 47 percent from 2005 levels, and expands the carbon sink target to 3.5 to 4 billion tonnes of CO₂ equivalent. Green hydrogen will play a critical role in achieving these targets.


The Green Hydrogen Certification of India (GHCI)

What Is GHCI?

The Green Hydrogen Certification Scheme of India (GHCI) is a government-backed certification system launched by the Ministry of New & Renewable Energy (MNRE).

The GHCI Digital Portal

The GHCI Digital Portal serves as the single-window platform where hydrogen producers register, submit production data, and receive government-backed certification confirming their hydrogen meets the emission threshold of 2 kg CO₂e/kg H₂.

How Green Hydrogen Generates Carbon Credits

The Basic Mechanism

Green hydrogen projects generate carbon credits by displacing fossil fuel-based hydrogen production and avoiding the associated emissions.

The Baseline Scenario

The baseline scenario is what would have happened without the green hydrogen project:

  • Hydrogen would have been produced using steam methane reforming (SMR) or coal gasification
  • These processes generate significant CO₂ emissions

The Project Scenario

The project scenario includes:

  • Hydrogen production through electrolysis using renewable electricity
  • Zero direct emissions from hydrogen production
  • Displacement of fossil fuel-based hydrogen

The Emission Reduction Formula

Emission Reductions (tCO₂e) = Baseline Emissions – Project Emissions – Leakage

The Key Variables

VariableDescription
Hydrogen productionVolume of green hydrogen produced
Baseline emission factorEmissions from fossil fuel-based hydrogen production
Grid emission factorEmissions intensity of the electricity used
Renewable sharePercentage of renewable electricity in the mix

The Emission Threshold

To qualify as "green" and generate carbon credits, hydrogen must meet the emission threshold of 2 kg CO₂e/kg H₂.


The Regulatory Framework: CCTS Offset Mechanism

The Offset Mechanism

Under India's Carbon Credit Trading Scheme (CCTS), green hydrogen projects can participate through the Offset Mechanism. This voluntary mechanism enables non-obligated entities to register eligible projects and earn Carbon Credit Certificates (CCCs).

The CCTS Framework

The CCTS includes a voluntary offset market open to all entities, enabling projects in renewable energy, biogas, green hydrogen, afforestation, and waste management to register and earn tradable carbon credits.

Approved Methodologies

In March 2025, the Ministry of Power approved eight initial crediting methodologies spanning renewable electricity generation, green hydrogen production, industrial energy efficiency, landfill methane recovery, and nature-based solutions.

The government has stated there will be methodologies for green hydrogen from electrolysis, and from biomass.
