Maruti Suzuki Commissions India's First Automotive Green Hydrogen Electrolyser Plant at Manesar, Haryana

Why in News

On September 24, 2026, Maruti Suzuki India Limited commissioned a 300 kilowatt (kW) green hydrogen electrolyser plant at its Manesar manufacturing facility in Gurugram district, Haryana. This is the first green hydrogen plant installed by an automotive manufacturer in India. The plant uses surplus solar power — generated at Manesar during holidays and weekends when manufacturing operations are paused — to produce green hydrogen via electrolysis. The hydrogen is stored and subsequently blended with natural gas as a process fuel in manufacturing operations, reducing the facility's dependence on fossil fuels.

Background

India's National Green Hydrogen Mission (NGHM), approved by the Union Cabinet on January 4, 2023 with an outlay of ₹19,744 crore, targets production of 5 million metric tonnes (MMT) of green hydrogen per year by 2030. The Mission also aims to create over 6 lakh jobs, develop 125GW of associated renewable energy capacity, and reduce fossil fuel imports by ₹1 lakh crore annually. India aspires to become a global hub for green hydrogen production and export, particularly to Europe and East Asia.

Green hydrogen is produced by splitting water (H₂O) using electricity generated from renewable sources — primarily solar or wind — through a process called electrolysis. Because no fossil fuels are burned in the process, the resulting hydrogen has near-zero lifecycle greenhouse gas (GHG) emissions, unlike grey hydrogen (from natural gas, high CO₂) or blue hydrogen (from natural gas with Carbon Capture and Storage — CCS). Green hydrogen is considered essential for decarbonising hard-to-abate sectors: steel, cement, fertilisers, heavy transport, and industrial process heat.

Current Developments

The Manesar Plant — Technical Details

• Capacity: 300kW Proton Exchange Membrane (PEM) electrolyser — a type of water electrolysis technology that uses a solid polymer membrane as the electrolyte.
• Energy source: Surplus solar power generated at Manesar during non-production hours (holidays, weekends).
• Output: Green hydrogen, which is stored and blended with natural gas for use in manufacturing process heat applications (e.g., painting shop ovens, heat treatment furnaces).
• Status: Pilot project; Maruti Suzuki will study results before scaling to other facilities in Haryana (Gurugram) and Gujarat (Hansalpur).

Sustainability Targets

Maruti Suzuki has set a corporate climate target to reduce manufacturing carbon emissions from approximately 615,000 tonnes CO₂e per year to 266,000 tonnes by FY2031 — a reduction of over 56%. The green hydrogen plant is one pillar of this strategy, alongside:

• Solar power expansion: Rooftop and ground-mounted solar across manufacturing facilities.
• Biogas plant (10 TPD): A 10-tonne-per-day biogas plant is under commissioning for FY2026-27, using food and industrial waste from Manesar.
• Energy efficiency: Variable speed drives, LED lighting, heat recovery systems across the plant.

Key Facts

Legal Framework

• National Green Hydrogen Mission (2023) — Cabinet approval; administered by MNRE; provides strategic interventions for production, storage, transport, and use of green hydrogen.
• SIGHT Programme (Strategic Interventions for Green Hydrogen Transition) — Competitive bidding for green hydrogen and green ammonia production under NGHM; MNRE launches tranches annually.
• Green Hydrogen Standards (2023) — Ministry of New and Renewable Energy notified India's first Green Hydrogen Standard, defining well-to-gate GHG intensity thresholds (≤2 kg CO₂e per kg H₂ for "green" designation).
• Energy Conservation Act, 2001 (amended 2022) — Introduced Carbon Credit Trading Scheme (CCTS) and mandated renewable energy use for designated consumers; green hydrogen producers can earn carbon credits under CCTS.
• Petroleum and Natural Gas Regulatory Board (PNGRB) Act, 2006 — Governs natural gas pipelines; amendments are under consideration to regulate hydrogen blending norms in city gas distribution (CGD) networks.

Institutional Framework

• Ministry of New and Renewable Energy (MNRE) — Nodal ministry for NGHM; administers SIGHT and Green Hydrogen Standard.
• Ministry of Petroleum and Natural Gas (MoPNG) — Oversees natural gas blending policy; CGD network regulation.
• NTPC Ltd. — PSU developing large-scale green hydrogen projects (Vindhyachal, Simhadri pilot plants); sets benchmarks for cost and scale.
• SECI (Solar Energy Corporation of India) — Conducts SIGHT auctions on behalf of MNRE.
• Bureau of Energy Efficiency (BEE) — Administers CCTS and energy labels.

Economic Dimensions

• Import substitution: India imports approximately USD 160 billion in fossil fuels annually; replacing a share with domestically produced green hydrogen can significantly reduce the import bill and improve the current account deficit.
• Industrial decarbonisation: Hard-to-abate industries (steel, cement, fertilisers) account for ~30% of India's GHG emissions; green hydrogen is one of few technically feasible zero-carbon options for these sectors.
• Export potential: India can leverage its abundant solar and wind resources to produce green hydrogen at competitive costs (targeting USD 1/kg by 2030 under NGHM) and export to Japan, South Korea, Germany, and Netherlands.
• Cost trajectory: Current green hydrogen production cost in India: approximately USD 4–5/kg; commercial viability requires reaching USD 1–2/kg — dependent on electrolyser cost reduction and cheap renewable electricity.

Banking & financial angle: Green hydrogen projects qualify for Priority Sector Lending (PSL) sub-category of Renewable Energy under RBI Master Directions. NABARD has a dedicated green financing window; SBI, HDFC Bank, and Bank of Baroda have all extended project finance to green hydrogen pilots in India. The Government's SIGHT scheme provides viability gap funding (VGF) to bridge the cost gap between green and grey hydrogen — a mechanism similar to DISCOMS' payment security under the power sector.

Environmental Dimensions

• Lifecycle emissions: Green hydrogen from PEM electrolysis (using solar) produces approximately 0.5–1 kg CO₂e per kg H₂ — well below India's 2 kg threshold standard, and far below grey hydrogen (~10–12 kg CO₂e/kg) or blue hydrogen (~4–6 kg CO₂e/kg with CCS).
• Water consumption: Electrolysis requires approximately 9 litres of pure water per kg of H₂ produced — a concern in water-scarce states; Haryana's groundwater stress makes efficient water use critical.
• NDC alignment: India's NDC includes reducing emissions intensity of GDP by 45% by 2030 over 2005 levels; green hydrogen in industry and transport contributes to this target.
• SDG 7 (Affordable and Clean Energy) and SDG 13 (Climate Action) are directly advanced.

Challenges

• Cost: At USD 4–5/kg (2026), green hydrogen is 3–4x more expensive than grey hydrogen; industrial adoption without subsidy is limited.
• Electrolyser manufacturing: India has minimal domestic electrolyser manufacturing capacity; most electrolysers (PEM and alkaline) are imported from Germany, Denmark, and China.
• Storage and transport: H₂ has very low volumetric energy density; storage (compressed, liquefied, or as ammonia/LOHC carriers) and pipeline transport infrastructure is nascent in India.
• Water availability: Electrolysis requires pure water; siting large plants in water-scarce areas (Rajasthan, Gujarat) poses challenges — desalination adds to cost.
• Scale transition: Moving from 300kW pilots to GW-scale plants requires de-risked project finance, long-term offtake agreements, and technology standardisation — none of which are yet in place.

Government Initiatives

• National Green Hydrogen Mission (2023): ₹19,744 crore; 5 MMT/year by 2030; SIGHT auctions for production incentives.
• SIGHT Programme: Tranches for green hydrogen and green ammonia production; attracts private investment.
• Green Hydrogen Standard (2023): ≤2 kg CO₂e/kg threshold; certification framework under development.
• Kandla Green Hydrogen Hub (2025–26): India's first port-based green hydrogen hub; MoPNG + MNRE initiative; designed for H₂ export via ammonia.

• India-Germany Green Hydrogen Partnership: USD 550 million investment announced in 2022; German companies providing electrolysis technology.

Way Forward

• NITI Aayog's India Energy Security Scenarios (IESS) 2047 model projects green hydrogen reaching 10–15% of India's final energy demand by 2047 — achievable only with electrolyser cost reduction to USD 200–300/kW (from ~USD 800–1,000/kW today).
• Develop a National Hydrogen Grid Master Plan (as recommended by the Petroleum and Natural Gas Regulatory Board): designated H₂ pipelines connecting production centres (Rajasthan, Gujarat) to industrial hubs (Odisha steel belt, Surat chemicals cluster).
• Mandate a Renewable Purchase Obligation (RPO) equivalent for green hydrogen — requiring fertiliser, steel, and cement industries above a threshold to source a rising fraction of their H₂ from green sources by 2030 (as proposed in Economic Survey 2025-26).
• Establish a Hydrogen Skills Development Programme under NSDC (National Skill Development Corporation) to train 50,000 technicians in electrolyser operation and H₂ safety by 2027 — addressing India's human capital gap.
• Fast-track domestic electrolyser manufacturing through a dedicated PLI component for electrolysis equipment (as recommended by the Parliamentary Standing Committee on Energy, 2024).

FAQ

Q: What is the difference between green, grey, and blue hydrogen?

A: Grey hydrogen is produced via Steam Methane Reforming (SMR) of natural gas, releasing ~10–12 kg CO₂ per kg H₂ — the most common (and cheapest) current method. Blue hydrogen also uses SMR but captures the CO₂ via Carbon Capture and Storage (CCS), reducing emissions to ~4–6 kg CO₂/kg H₂. Green hydrogen is produced by electrolysis of water using renewable electricity — near-zero lifecycle emissions (≤2 kg CO₂e/kg H₂ under India's standard). Green hydrogen is the most expensive today but the most sustainable long-term.

Q: What is the National Green Hydrogen Mission and what are its targets?

A: Approved by Union Cabinet on January 4, 2023, the NGHM has an outlay of ₹19,744 crore. Its targets by 2030 include: (a) 5 million metric tonnes (MMT) of green H₂ production per year; (b) 125GW of associated renewable energy capacity; (c) over 6 lakh jobs created; (d) ₹1 lakh crore reduction in fossil fuel imports. MNRE administers the Mission through the SIGHT programme (production incentives), R&D funding, and infrastructure development.

Q: What is a PEM electrolyser and how does it work?

A: A Proton Exchange Membrane (PEM) electrolyser uses a solid polymer (Nafion membrane) as the electrolyte. Water is fed at the anode, where it is split into O₂, protons (H⁺), and electrons. Protons pass through the membrane to the cathode, where they combine with electrons to form H₂ gas. PEM electrolysers are compact, fast-responding (suitable for intermittent renewable power), and produce high-purity hydrogen — making them ideal for small-to-medium scale plants like Maruti's 300kW Manesar unit.
