Introduction
The water-gas shift reaction (WGSR) is a chemical reaction used to increase hydrogen yield from synthesis gas (syngas).

🧠 What It Means
CO + H₂O → CO₂ + H₂
Used after steam methane reforming (SMR) or gasification.
Produces more hydrogen by reacting carbon monoxide with steam.
❗ Key Challenges
Produces CO₂ as a byproduct (not “green”).
Requires high temperature and catalysts.
Needs CO₂ capture for decarbonisation.
🦁 Muzaffar’s Comment
“It’s the chemical trick to squeeze out extra hydrogen from fossil fuels.”
🦉 Sameer’s Comment
“More hydrogen, same carbon input — efficient but not clean without CCS.”
