Steam methane reforming technique is used to obtain
Detailed Explanation:
Steam Methane Reforming (SMR) reacts natural gas (methane) with high-temperature steam to produce hydrogen and carbon dioxide (CO₂) as a by-product.
Since the process emits CO₂ without carbon capture, the hydrogen produced is classified as Grey Hydrogen. Brown Hydrogen comes from coal gasification, while Green Hydrogen is produced via water electrolysis using renewable energy with zero emissions.
How is Hydrogen stored physically?
Detailed Explanation:
Physical storage of hydrogen means storing H₂ gas without any chemical transformation.
Compressing hydrogen gas into high-pressure tanks (350–700 bar) is the most common physical storage method – no chemical bonds are formed or broken.
Hydrides involve chemical bonding with metals/alloys (chemical storage), and water (H₂O) is a compound, not free hydrogen gas.
