What is Green Hydrogen?
Green Hydrogen is hydrogen produced using renewable energy sources (solar, wind) via electrolysis. Unlike grey hydrogen (from fossil fuels) or blue hydrogen (with carbon capture), Green Hydrogen is 100% carbon-free, making it crucial for global climate goals.
Key Features of Green Hydrogen:
- Zero Emissions: Produced using renewable electricity.
- High Energy Density: 3x the energy per unit mass compared to gasoline.
- Versatile Applications: Used in industries, mobility, and power storage.
- Scalability: Can be produced on-site or transported via pipelines.
According to the International Energy Agency (IEA), green hydrogen is set to play a crucial role in the global energy transition.
Advantages of Green Hydrogen Over Other Types of Fuels
- Zero Carbon Emissions: Green hydrogen is produced using renewable energy sources and does not release CO₂, making it a clean alternative to fossil fuels.
- Renewable & Sustainable: Unlike fossil fuels, hydrogen can be produced indefinitely using water and renewable energy (solar, wind, hydro).
- High Energy Density: Hydrogen has a higher energy density than gasoline, diesel, or batteries, making it efficient for long-range transportation and heavy industries.
- Versatile Applications: Can be used in transportation (fuel cell vehicles), power generation, industrial heating, and energy storage.
- Supports Energy Independence: Reduces reliance on imported fossil fuels, helping countries achieve energy security.
- Better Grid Integration: Hydrogen can store excess renewable energy and be used later, helping balance the grid and ensuring continuous energy supply.
- Non-Toxic & Safe to Handle: Unlike fossil fuels, hydrogen is non-toxic and disperses quickly, reducing risks in case of leaks.
- Decarbonizing Hard-to-Abate Sectors: Essential for industries like steel, cement, shipping, and aviation, where direct electrification is difficult.
How is Green Hydrogen Produced?
Electrolysis Process: Splits water (H₂O) into hydrogen (H₂) and oxygen (O₂) using renewable electricity.
Electrolysis: The Core Process
Electrolysis occurs in an electrolyser, a device that consists of:
- Two electrodes (anode & cathode): Conducts electricity and facilitates hydrogen production.
- Electrolyte: A solution or membrane that enables ion exchange.
- Renewable power source: Solar, wind, or hydroelectricity provides the required energy.
Reaction in Electrolysis:
This process generates pure hydrogen, which can be stored, transported, and used as an energy carrier in industries, mobility, and power generation.
Types of Green Hydrogen Electrolysis:
1. Proton Exchange Membrane (PEM) Electrolysis
✔ Uses a solid polymer membrane.
✔ High efficiency, rapid response to renewable energy fluctuations.
✔ Ideal for mobility applications.
2. Alkaline Electrolysis
✔ Uses a liquid alkaline solution (KOH or NaOH).
✔ Mature, cost-effective for large-scale production.
3. Solid Oxide Electrolysis (SOE)
✔ Operates at high temperatures (700-1,000°C).
✔ Integrates with industrial waste heat for efficiency.
✔ Suitable for steel production & high-temperature industries.
The Hydrogen Council reports that green hydrogen demand is rapidly increasing across industries worldwide.
