Green Hydrogen Electrolysers are the backbone of clean hydrogen production, enabling the transition to a zero-emission future. By using renewable electricity to split water into hydrogen and oxygen, electrolysers provide a sustainable way to produce hydrogen without carbon emissions.
As a global leader in Green Hydrogen technology, ORAIPL manufactures high-capacity electrolysers (60-100 GW) to support industrial hydrogen production, mobility pilot projects, and hydrogen shipping applications.
What is a Green Hydrogen Electrolyser?
An electrolyser is an advanced device that splits water (H₂O) into hydrogen (H₂) and oxygen (O₂) using electricity. This process, called electrolysis, is recognized by the International Energy Agency (IEA) as one of the key technologies for scaling up global hydrogen production and achieving net-zero targets.
The Electrolysis Process
1. Water Input → Purified water is supplied to the electrolyser.
2. Electricity Input → DC power from renewable sources is applied.
3. Electrolysis Reaction → Water molecules split into hydrogen (H₂) and oxygen (O₂).
4. Hydrogen Collection → Hydrogen gas is stored or transported for use.
Key Fact: 1 liter of water can produce 111 grams of hydrogen!
Types of Green Hydrogen Electrolysers
There are three main types of electrolysers used for green hydrogen production:
1. Alkaline Electrolysers (AEL)
- Mature & cost-effective technology
- Uses liquid alkaline solution (KOH or NaOH) as an electrolyte
- Best for large-scale hydrogen production
- Lower efficiency compared to other types
Best for: Industrial-scale green hydrogen plants
2. Proton Exchange Membrane (PEM) Electrolysers
- High efficiency & fast response to variable renewable energy
- Uses a solid polymer membrane as an electrolyte
- Operates at high pressures (30-80 bar), reducing storage costs
- More expensive than alkaline electrolysers
Best for: Hydrogen mobility, refueling stations, decentralized applications
3. Solid Oxide Electrolysers (SOECs)
- Operates at high temperatures (700-1000°C)
- Uses ceramic membranes, allowing higher efficiency
- Can integrate with industrial waste heat to improve efficiency
- Still in early-stage commercialization
Best for: Steel plants, chemical industries, and high-temperature applications

Efficiency & Cost of Electrolysis
Electrolyser efficiency is measured in kilowatt-hours (kWh) per kg of hydrogen produced. According to the US Department of Energy (DOE), ongoing advancements in electrolyser technology and reductions in renewable energy costs are making green hydrogen production more affordable.
Efficiency Breakdown
| Electrolyser Type | Efficiency (%) | Energy Requirement (kWh/kg H₂) |
|---|---|---|
| Alkaline Electrolyser | 65-70% | 50-55 kWh/kg H₂ |
| PEM Electrolyser | 70-80% | 45-50 kWh/kg H₂ |
| SOEC Electrolyser | 80-85% | 40-45 kWh/kg H₂ |
Cost Trends of Electrolysis
-
Current Green Hydrogen Production Cost: $3-6/kg
-
Expected Cost by 2030: $1-2/kg (as projected by the Hydrogen Council, due to falling renewable energy costs & electrolyser advancements)
With ongoing R&D and economies of scale, electrolysis is becoming cheaper and more efficient, making green hydrogen competitive with fossil fuels.
Future Innovations in Electrolyser Technology
As outlined in the IEA Hydrogen Report, the next-generation green hydrogen electrolysers will be:
- Next-Gen Catalysts → New materials for higher efficiency & lower cost.
