GreenH Electrolysis: Scaling Up Hydrogen Electrolyser Technologies for India's Energy Transition
Mar 03, 2025
GreenH Electrolysis is positioning itself as a leading manufacturer of electrolysers and a developer of hydrogen supply projects, leveraging multiple technologies to drive the mass adoption of green hydrogen. The company, led by CEO Dhiman Roy, is focusing on mobility, oil & gas, and hard-to-abate industries such as steel and cement.
Key Focus Areas & Technologies:
- Electrolyser Manufacturing: GreenH currently employs PEM electrolysis and plans to introduce alkaline, AEM (Anion Exchange Membrane), and SOEC (Solid Oxide Electrolyser Cell) technologies in the coming years.
- First 1 MW PEM Electrolyser: Installed as a hydrogen refueling station (HRS), awaiting integration with a hydrogen train.
- Advantages of PEM Electrolyser:
- Better integration with renewable energy (works from 10?pacity vs. 50% for alkaline).
- Faster ramp-up times (minutes vs. hours for alkaline electrolysers).
- Compact footprint—ideal for space-constrained industries like refineries.
- Lower O&M costs, improving the levelized cost of hydrogen (LCOH).
Industry Adoption & Expansion Plans:
- Steel & Cement: Emerging as key sectors due to impending carbon credit regulations in Europe. Jindal Stainless Steel has already set up a green hydrogen facility.
- Alkaline Electrolyser Launch (2026): GreenH plans to introduce alkaline electrolysers in mid-2026, followed by SOEC and AEM technologies in 2027.
- Investment of INR 280 Crore: Structured in two phases to scale up production and new technology adoption.
Market & Collaboration Strategy:
- GreenH is not tied to a single technology but offers customized electrolyser solutions.
- No active partnerships currently, but the company is expanding its business independently.
- Industry events like India Energy Week (IEW) provide a crucial platform for networking, collaboration, and knowledge-sharing within the hydrogen sector.
