Introduction
Steam Methane Reforming (SMR) is the most common method for producing hydrogen by reacting methane (CH₄) with steam at high temperatures.

IEA Hydrogen Production Tech Brief
🧠 What It Means
CH₄ + H₂O → CO + 3H₂ (then CO + H₂O → CO₂ + H₂)
Produces “grey hydrogen” or “blue hydrogen” if paired with CCS.
Dominates global hydrogen production (over 90%).
❗ Key Challenges
High CO₂ emissions unless captured.
Relies on fossil fuel (natural gas).
Still cheaper than green hydrogen, limiting its replacement.
🦁 Muzaffar’s Comment
“SMR is efficient — but dirty. The challenge is cleaning it up, not throwing it out.”
🦉 Sameer’s Comment
“It built today’s hydrogen economy — but can’t carry us into tomorrow without change.”
