Hydrogen-Natural Gas Blending Calculator
Calculate blend properties and safety parameters for hydrogen-natural gas mixtures
How to Use This Calculator
Key Parameters Explained
Flow Rates
- Hydrogen Flow: Volume flow rate of hydrogen gas
- Natural Gas Flow: Volume flow rate of natural gas
System Conditions
- Pressure: Operating pressure of the blending system
- Temperature: Operating temperature of the gases
Example Calculation
Typical Scenario
Blending 100 m³/h hydrogen with 900 m³/h natural gas:
H₂ Flow: 100 m³/h
NG Flow: 900 m³/h
Result: 10% H₂ | 0.61 kg/m³ | 33.2 MJ/m³
Important Considerations
- Wobbe Index must be within ±5% of natural gas for appliance compatibility
- Maximum hydrogen content is typically limited to 20% by volume
- Higher hydrogen content increases flame speed and flashback risk
- Pipeline materials must be compatible with hydrogen embrittlement
Safety Notes
Monitor flammability limits carefully during blending
Higher hydrogen content increases pressure drop
