GS Paper 3:
Topics Covered: Conservation related issues.
Context:
The Centre is planning to use the green hydrogen fuel from wastewater by using solar energy. It is possible by using electrolyzers.
How this can be achieved?
By segregation of solid waste management using the rooftop solar, we can make green hydrogen with the help of electrolysers. The power and water cost of producing it would be negligible. We can use this fuel even in railway engines along with cement and chemical companies instead of coal.
Challenges:
The path for green hydrogen in the country is not clear and at the moment, production of green hydrogen is slightly more expensive than grey hydrogen.
What is green hydrogen?
Hydrogen when produced by electrolysis using renewable energy is known as Green Hydrogen which has no carbon footprint.
Significance of Green Hydrogen:
- Green hydrogen energy is vital for India to meet its Nationally Determined Contribution (INDC) Targets and ensure regional and national energy security, access and availability.
- Green Hydrogen can act as an energy storage option, which would be essential to meet intermittencies (of renewable energy) in the future.
- In terms of mobility, for long distance mobilisations for either urban freight movement within cities and states or for passengers, Green Hydrogen can be used in railways, large ships, buses or trucks, etc.
Applications of green hydrogen:
- Green Chemicals like ammonia and methanol can directly be utilized in existing applications like fertilizers, mobility, power, chemicals, shipping etc.
- Green Hydrogen blending up to 10% may be adopted in CGD networks to gain widespread acceptance.
Benefits:
- It is a clean-burning molecule, which can decarbonize a range of sectors including iron and steel, chemicals, and transportation.
- Renewable energy that cannot be stored or used by the grid can be channelled to produce hydrogen.
