Q. Consider the following statements regarding natural hydrogen:
1.It is also known as the blue hydrogen.
2.It can be produced from the process of serpentinisation.
3.Relative cost of white hydrogen is lesser than green hydrogen.
Which of the statements given above are correct?
Answer: B
Notes:
Explanation: Statements 2 and 3 are correct
Statement 1 is incorrect: Natural hydrogen is also called white/gold/geological hydrogen, to distinguish it from “green” (from renewables), “blue” (from natural gas with carbon capture), or “grey” (from fossil fuels) hydrogen.
Statement 2 is correct: Production: It is produced by processes such as –
- Serpentinisation – It is a geological process where ultramafic rocks are altered by water and heat, transforming them into serpentinite. This process also releases hydrogen gas.
- Radiolysis of water by radioactive rocks
- From organic matter at depth.
Statement 3 is correct: White hydrogen’s estimated cost is around $1 per kilogram, significantly lower than green hydrogen, which costs about $6 per kilogram, making it a more affordable clean energy source.
