The green hydrogen sector in 2025 is rapidly emerging as a crucial part of the global energy transition, driven by its status as a zero-carbon fuel produced through renewable energy-powered electrolysis.
In India, the green hydrogen sector is gaining particular momentum. The National Green Hydrogen Mission has set ambitious production goals targeting 5 million metric tonnes annually by 2030, aiming for India to capture a 10% share of global demand and become a green hydrogen export hub.
Electrolyser manufacturing capacity is rapidly developing, with allocations to numerous firms, and substantial projects are underway, supported by strong government policies and private sector commitments.
Reliance Industries Ltd (RIL) is building a new energy ecosystem across solar, storage, green hydrogen, and sustainable chemicals. Under India’s Green Hydrogen Mission, RIL aims for 5 MMTPA production capacity by 2030.
The company is also constructing a 30 GWh advanced battery giga factory, set for commissioning in 2025/26. This facility will first assemble Battery Energy Storage Systems (BESS) and later expand into cell manufacturing and battery chemicals, making it the world’s only fully integrated battery giga factory.
In addition, RIL plans to operationalise a multi-GW electrolyser facility to strengthen green hydrogen production. The company has entered into a licensing agreement with Nel Hydrogen Electrolyser AS, granting it exclusive rights to manufacture and use alkaline electrolysers in India and for global captive requirements. Through these initiatives, Reliance is advancing the shift from conventional fuels toward green hydrogen and renewable electricity.

Larsen & Toubro (L&T) is accelerating its clean energy transition with a strong focus on Green Hydrogen and derivatives. Electrolyser manufacturing has already begun, providing an early advantage, with initial collaborations with global technology partners laying the foundation for a future shift toward indigenously developed technology and equipment.
L&T Energy Green Tech Limited (LTEGL), a wholly owned subsidiary, has received incentives under the SIGHT programme to set up 90 KTPA Green Hydrogen capacity in India, with a maximum allocation of ₹300 crore over three years. Additionally, LTEGL has secured 500 acres at Kandla port, Gujarat, on a 30-year lease to establish Green Hydrogen and Green Ammonia plants.
L&T aims to deliver turnkey clean energy solutions by integrating renewable power with hydrogen production, covering EPC projects in Green Hydrogen, Green Ammonia, and Methanol. Backed by India’s ₹20,000 crore National Green Hydrogen Mission (5 MMTPA capacity target by 2030), L&T is positioned to serve global markets.

ONGC’s Energy Strategy 2040 sets a roadmap to double oil and gas production, triple portfolio revenue, and quadruple profit, with at least 10% from non-hydrocarbon businesses. A key pillar of this strategy is green hydrogen, where ONGC targets 0.15 million MT/year capacity by 2038, requiring 1.15 GW of renewable power per MMT/day.
This shift is supported by an MoU signed in January 2025 with BHEL to jointly explore the entire green hydrogen value chain, including electrolyser technology, storage, fuel cells, hydrogen-fired turbines, and captive RTC power applications. A feasibility study has also been completed for green hydrogen generation using 2.2 MW of renewable power at the Dahej plant.
To enable low-carbon growth, ONGC is investing in renewables, scaling from 194 MW to over 4.1 GW via Ayana Renewable Power. It is also exploring carbon capture, biofuels, LNG, and geothermal solutions.

In 2024-25, IndianOil advanced its alternative energy and petrochemical ambitions through integrated refinery-petrochemical complexes, speciality chemicals, and import substitution, while also expanding into renewable energy, biofuels, sustainable aviation fuel (SAF), and waste-to-energy.
The company is centred on its strategy of green hydrogen, with a flagship 10,000 tonnes per annum plant at Panipat scheduled for December 2027 and a target to convert 50% of current hydrogen consumption to green by 2030. The company is investing ₹2.5 lakh crore to achieve Net-Zero operational emissions by 2046, backed by renewable electricity integration, carbon capture, tree plantation, and efficiency initiatives.
Aligned with the National Green Hydrogen Mission (outlay of ₹19,744 crore), tenders for 4.12 lakh tonnes per annum capacity and 1,500 MW of electrolyser manufacturing have been awarded. IndianOil is also pursuing 31 GW renewable capacity by 2030, SAF and 30 CBG plants, EV charging and battery swapping, while scaling green hydrogen to support oil refining, steel, and heavy transport.
Overall, the green hydrogen sector is set for substantial expansion globally and in India, with optimistic forecasts for market size, technology breakthroughs, and wider adoption across multiple industries by 2025 and beyond.
