CEN Standards for Hydrogen Blending
🧠 What It Means
Wobbe Index = (Heating Value) / √(Relative Density)
Two fuels with the same Wobbe Index can be swapped in burners without altering performance.
Crucial for hydrogen blending into gas grids.
❗ Key Challenges
Hydrogen’s Wobbe Index is much lower than natural gas.
Appliances may need adjustment or replacement.
Misalignment can cause inefficiencies or safety issues.
🦁 Muzaffar’s Comment
“The Wobbe Index tells you if your gas will play nice in the system.”
🦉 Sameer’s Comment
“It’s the reason you can’t just swap hydrogen into old boilers — the math matters.”
