What is Green Hydrogen?
Green hydrogen is produced when water is electrolyzed into hydrogen and oxygen using electricity sourced entirely from renewable energy solar, wind, or hydropower. Unlike grey or blue hydrogen derived from fossil fuels, it carries zero carbon emissions, making it a clean and sustainable energy carrier. It can be stored for long periods, transported over long distances, and reconverted to electricity or used directly as fuel, giving it unique applicability across global decarbonization strategies and net-zero pathways.
The primary production method is water electrolysis. The complete process involves water purification and treatment, renewable power integration, electrolysis using alkaline, PEM (Proton Exchange Membrane), or SOEC (Solid Oxide Electrolyzer Cell) technologies, hydrogen drying and purification, compression or liquefaction, storage, and dispatch. End-use sectors include refining, chemicals and fertilizers, steel manufacturing, power generation, transportation, and energy storage. The product also serves as feedstock for green ammonia, methanol, and synthetic fuels.
Cost of Setting Up a Green Hydrogen Manufacturing Plant in India
The cost of establishing a green hydrogen manufacturing plant in India depends on plant capacity, electrolysis technology, site location, automation level, and regulatory compliance. A rigorous feasibility study is an essential prerequisite before committing capital.
1. Capital Expenditure (CapEx)
Land and site development covering land registration, boundary work, and utility infrastructure represent a substantial share of total capital investment. Siting the facility within a Special Economic Zone (SEZ) or renewable energy industrial estate can reduce costs and provide regulatory advantages. Civil works, including the production shed, quality laboratory, raw material storage, and administrative block, form the next major investment layer. Machinery costs account for the largest individual component of total CapEx.
Key machinery required includes:
- Electrolyzers (alkaline, PEM, or SOEC)
- Rectifiers
- Compressors
- Storage tanks
- Safety valves
- Monitoring systems
- Water purification systems
- Renewable energy integration equipment (solar or wind)
- Hydrogen compressors
- Gas purification units
- Cooling systems
- Safety and control infrastructure
Other capital costs include the effluent treatment plant (ETP), pre-operative and commissioning expenses, and import duties on specialized electrolyzer components.

2. Operational Expenditure (OpEx)
Raw material costs are the dominant driver of operating expenses. Deionized water, renewable electricity (solar/wind), electrolyzer stacks, and catalysts including those containing platinum, iridium, nickel, and specialized ceramic oxide membranes account for 60–70% of total OpEx. Long-term supplier contracts are essential to stabilize costs and guard against supply chain disruptions. Utility costs covering electricity, water, and cooling represent a further 10–15% of OpEx. Additional costs include transportation, packaging, salaries, maintenance, depreciation, and taxes. Total operational costs are projected to increase substantially by the fifth year of operations, driven by inflation, market fluctuations, and rising input costs.
3. Plant Capacity
The production facility is designed for annual output between 10,000 and 50,000 MT, enabling economies of scale while preserving operational flexibility. Capacity can be customized to match investor requirements and available renewable energy supply. Profitability improves significantly with higher capacity utilisation, making facility sizing a critical strategic decision.
4. Profit Margins and Financial Projections
This type of production facility demonstrates strong profitability potential under normal operating conditions. Gross profit margins typically range between 30–50%, supported by stable industrial demand and value-added downstream applications, while net profit margins range between 10–20%. A comprehensive financial plan should incorporate NPV, IRR, and payback period analysis. Break-even timelines typically range from 5 to 10 years, influenced by plant size, energy costs, capital investment, government incentives, and market demand.
Why Set Up a Green Hydrogen Plant in India?
Net-Zero Commitments and National Policy Support. India’s National Green Hydrogen Mission targets 5 MMT of annual production by 2030, has attracted INR 8 Lakh Crore in investments, launched mobility and port-based pilots, and aims to cut fossil fuel import dependency providing a comprehensive and uniquely supportive policy environment for investors entering domestic production.
Demand from Hard-to-Abate Industrial Sectors. Refining, chemicals and fertilizers, steel manufacturing, and heavy transport are industries that cannot be decarbonized through electrification alone. These sectors are actively transitioning to low-carbon feedstocks, creating durable, long-term domestic demand for green hydrogen producers at every production scale.
Cost-Competitive Renewable Energy Foundation. Declining solar and wind costs are directly improving the economics of the green hydrogen manufacturing process. According to IRENA, renewable energy costs fell in 2024, with solar PV power averaging 41% lower than the cheapest fossil fuel alternatives and onshore wind 53% cheaper conditions particularly favourable across India’s renewable-rich states.
Active Global Investment Signaling Industry Maturity. In July 2025, China’s Envision Energy inaugurated the world’s largest green hydrogen and ammonia plant in Chifeng, Inner Mongolia entirely renewable-powered, AI-operated, and producing 320,000 tonnes annually demonstrating the rapid commercial scaling of the sector. India’s Mission positions domestic investors to benefit from this global momentum.
Expanding Downstream and Export Opportunities. Rapid integration with applications such as green ammonia, e-methanol, and sustainable aviation fuels is widening the addressable revenue base significantly. The emergence of cross-border hydrogen supply chains and export-oriented production hubs creates additional high-value revenue pathways for Indian producers.
Manufacturing Process Step by Step
The green hydrogen manufacturing process uses water electrolysis as the primary production method, with all electricity sourced from renewable energy. The process follows these unit operations:
- Water Purification and Treatment: Raw water is processed to produce deionized water of the quality required for electrolysis input.
- Renewable Power Integration: Electricity generated from solar, wind, or hydropower is integrated to power the electrolyzer stacks.
- Electrolysis: Purified water is split into hydrogen and oxygen inside electrolyzers operating on alkaline, PEM, or SOEC technology.
- Hydrogen Drying and Purification: Raw hydrogen is processed through gas purification units and drying systems to reach target purity specifications.
- Compression or Liquefaction: Purified hydrogen is compressed using hydrogen compressors or liquefied, depending on storage and transport requirements.
- Storage: Compressed or liquefied hydrogen is held in storage tanks under controlled pressure and temperature conditions.
- Quality Assurance and Testing: Product purity, concentration, and stability are verified by analytical instruments before dispatch.
- Dispatch: Finished product is distributed to customers in refining, steel manufacturing, chemicals, power generation, and transportation sectors.
