What is Green Hydrogen?
Historical Background
Key Points
8 points- 1.
Produced via electrolysis of water (H2O → H2 + O2) using renewable electricity.
- 2.
Offers high energy density by weight, making it suitable for storage and transport.
- 3.
Versatile applications: fuel for transport (fuel cells), industrial feedstock (ammonia, steel), power generation, and energy storage.
- 4.
Crucial for decarbonizing hard-to-abate sectors like steel, cement, fertilizers, and heavy-duty transport.
- 5.
Challenges include high production cost, storage and distribution infrastructure, and energy efficiency of electrolysis.
- 6.
Categorized by production method: Green (renewables), Blue (natural gas with Carbon Capture), Grey (natural gas without Carbon Capture).
- 7.
India aims for 5 million tonnes per annum (MTPA) green hydrogen production by 2030.
- 8.
Expected to attract substantial investment and create jobs, reducing reliance on fossil fuels.
