L&T, Reliance and Advait Share 300 MW Hydrogen Capacity
Electrolysers are machines that use electricity to separate water into hydrogen and oxygen.
Hydrogen made with clean electricity is called green hydrogen.
L&T, Reliance and Advait have each been awarded 300 MW of potential yearly electrolyser-making capacity under a government programme.
This does not mean that all three companies are equally large or are already producing the same amount.
L&T is using its engineering and construction experience.
Reliance is building a much bigger clean-energy system involving solar power, batteries and green fuels.
Advait is much smaller and is trying to grow through electrolysers, hydrogen equipment and projects.
The companies now need to build facilities, prove their equipment works and turn opportunities into confirmed orders.
L&T Electrolysers, Reliance Electrolyser Manufacturing and Advait Energy Transitions each hold 300 MW of SIGHT-linked annual electrolyser manufacturing capacity.
L&T is combining electrolyser production with engineering, construction and green hydrogen, ammonia and methanol projects.
Reliance’s electrolyser plans are part of a broader programme involving renewable power, solar manufacturing, batteries and green fuels.
Advait has commissioned a 30 MW alkaline electrolyser assembly facility and demonstrated a 5 MW test batch to more than 13 Indian green hydrogen companies.
Advait’s planned 300 MW facility is targeted for operation in Q4 FY27, while its estimated 150–200 MW supply opportunity remains based on enquiries rather than confirmed orders.
- Who
- L&T Electrolysers, Reliance Electrolyser Manufacturing and Advait Energy Transitions.
- What
- The three companies each have 300 MW of SIGHT-linked annual electrolyser manufacturing capacity, but are pursuing different green hydrogen strategies.
- When
- The National Green Hydrogen Mission was approved in January 2023; Advait commissioned its 30 MW facility in March 2026 and targets Q4 FY27 for its planned integrated complex.
- Where
- The companies’ activities are in India; L&T’s disclosed electrolyser manufacturing is at Hazira, and Advait’s planned integrated complex is at Gangad, Gujarat.
- Why
- Electrolysers are needed to produce green hydrogen, and India is supporting domestic manufacturing and green hydrogen production through the SIGHT programme.
Capacity Comparison
Scale and Execution Context
Meaning of 300 MW
Capacity Comparison
The three companies appear comparable on the specific government-backed metric of 300 MW annual electrolyser manufacturing capacity.
Scale and Execution Context
The identical allocation does not establish equal operating scale, output, financial resources, revenue or confirmed orders.
Business strategy
Capacity Comparison
Advait is building a focused business around electrolysers, balance-of-plant systems, hydrogen project execution and fuel cells.
Scale and Execution Context
L&T is pursuing large engineering and industrial projects, while Reliance is integrating electrolysers into a wider renewable-energy and green-fuels programme.
Commercial readiness
Capacity Comparison
Advait has commissioned a 30 MW assembly facility, tested a 5 MW batch and identified 150–200 MW of potential demand through enquiries.
Scale and Execution Context
The larger 300 MW facility is not yet operational, the enquiries are not confirmed orders, and separate electrolyser production, revenue and order-book figures were not disclosed for any of the three companies.
- SIGHT capacity
- L&T, Reliance and Advait each have 300 MW of annual electrolyser manufacturing capacity; Advait’s total comprises 100 MW under Tranche-I and 200 MW under Tranche-II.
- National target
- India’s National Green Hydrogen Mission targets 5 million metric tonnes per annum of green hydrogen production capacity by 2030.
- Mission outlay
- The National Green Hydrogen Mission was approved with an outlay of Rs 19,744 crore.
- Government awards
- As of December 2025, 15 companies had received awards totaling 3,000 MW of annual electrolyser manufacturing capacity, with aggregate incentives of Rs 4,440 crore.
- Advait facility
- Advait commissioned Phase-I of a 30 MW alkaline electrolyser assembly facility in March 2026.
- Advait opportunity
- Advait reported potential electrolyser supply of 150–200 MW from active enquiries, not confirmed orders.
- Reliance contract
- Reliance disclosed a Rs 24,900 crore green ammonia contract with Samsung C&T.
