Forest ServicesQ90. With reference to green hydrogen, Consider the following statements :
1. It can be used directly as a fuel for internal combustion.
2. It can be blended with natural gas and used as fuel for heat or power generation.
3. It can be used in the hydrogen fuel cell to run vehicles.
How many of the above statements are correct?
Detailed Solution
All three statements regarding green hydrogen are correct: 1. **Statement 1**: Hydrogen can be directly combusted in internal combustion engines, often with modifications, as a clean-burning fuel, producing water vapor as the primary emission.
2. **Statement 2**: Green hydrogen can be blended with natural gas and supplied through existing pipeline networks for use in industrial processes, heating, and power generation, thereby reducing the carbon footprint of natural gas consumption.
India has already initiated projects for blending green hydrogen into piped natural gas (PNG) networks. 3. **Statement 3**: Hydrogen fuel cells convert hydrogen and oxygen into electricity through an electrochemical process, producing only water as a byproduct.
This technology is used to power fuel cell electric vehicles (FCEVs), offering a zero-emission alternative. Green hydrogen is a key component of global decarbonization strategies, making it a highly relevant topic in current affairs and environmental technology.
