Statcon Energiaa Private Limited, a manufacturer of mission-critical power electronics, has secured an order from L&T Electrolysers Limited to supply high-power rectifiers for the 10 kTPA green hydrogen project being set up at the Indian Oil Corporation Limited (IOCL) Panipat Refinery & Petrochemical Complex, Haryana. The project is being built by L&T Energy GreenTech and is expected to be commissioned by December 2027. It is the first concrete step in IOCL’s ambition to generate 350 kTPA of green hydrogen by 2030.
L&T Electrolysers Limited is manufacturing high-pressure alkaline electrolysers in 4 MW modular blocks at its advanced facility in Hazira, Gujarat, making this India’s first large-scale green hydrogen project powered by indigenously manufactured electrolysers. Furthermore, Statcon Energiaa is supplying the 4 MW rectifier blocks that power those electrolysers, and these are also manufactured entirely in India. The rectifiers will use the powerful IGBT Chopper-based technology, backed by AEG Power Solutions, Germany. Built for high efficiency and round-the-clock performance, these are developed under Statcon Energiaa’s exclusive licensing and supply agreement with AEG Power Solutions GmbH, Germany. Under this agreement, Statcon Energiaa designs, assembles, commissions, and services these rectifiers on Indian soil, using AEG PS’s proven core components such as IGBT modules, thyristors, and more while engineering them specifically for India’s operating conditions.
Key technical highlights of the rectifiers:
- Topology: Thyristor-based 12-Pulse bridge with IGBT chopper
- Cooling: Liquid-cooled for sustained 24×7 operation
- Input: Engineered for high power quality from variable renewable (solar) energy sources – addressing one of the most demanding challenges in renewable-powered electrolysis
- Output: Low-ripple DC output, critical for efficient and stable alkaline electrolysis
- Block size: 4 MW per unit – mirroring L&T’s 4 MW electrolyser block in a truly modular, indigenous architecture
These rectifiers are required to operate continuously, drawing from intermittent solar or other renewable energy to feed electrolyser stacks that demand uncompromising power quality. Living up to that responsibility meant engineering to the most exacting technical requirements:
- Input line power quality: Handling variability from renewable sources without disrupting electrolyser performance
- Output stability and low DC ripple: Essential for efficient, consistent hydrogen generation
- Efficiency: Sustained thermal and electrical performance under continuous load
- Harmonic distortion control: Protecting electrolyser stacks and maximising operational longevity
- Proven reliability: Track record in mission-critical deployments
Statcon Energiaa’s rectifiers deliver all of these requirements, thereby ensuring the electrolysers powering IOCL’s green hydrogen project run reliably, around the clock.
Anil Dhar, Marketing Director, Statcon Energiaa said, “This order represents exactly what Statcon Energiaa has always stood for – delivering world-class technology, made in India, for India’s most critical infrastructure. L&T Electrolysers’ qualification process is among the most demanding we have encountered. Meeting every parameter – power quality, efficiency, harmonic performance, output stability, and reliability – reflects the maturity our technology and manufacturing have reached against rigorous global standards. What makes this especially meaningful is the symmetry of the project: L&T is building the 4 MW electrolyser block; we are building the 4 MW rectifier block that powers it. Both are Indian-made. For a company that has believed in Make in India since before it was a policy, this is a proud moment. India is not just consuming green hydrogen infrastructure – it is building it. For Statcon Energiaa, the opportunity to power a project of such national significance is both a privilege and a responsibility it is proud to carry.”
