Consider the following statements regarding hydrogen production:
1. Grey hydrogen is produced using Steam Methane Reformation without carbon
capture.
2. Blue hydrogen is completely carbon-neutral due to carbon capture and storage.
3. Green hydrogen currently constitutes about 5% of global hydrogen production.
4. Electrolysis is used in the production of both blue and green hydrogen.
How many of the statements given above are correct?
Explanation:
Statement 1 is correct. Grey hydrogen is produced using Steam Methane Reformation
without capturing the greenhouse gases.
Statement 2 is incorrect as blue hydrogen is not completely carbon-neutral, with 10-20%
of generated carbon not captured.
Statement 3 is incorrect as green hydrogen currently makes up only about 0.1% of
overall hydrogen production.
Statement 4 is incorrect as electrolysis is used specifically for green hydrogen
production, not blue hydrogen
