Hydrogen Storage Calculator
Calculate hydrogen mass in pressurized storage systems
Note:
The calculations provided by HyCalc are intended for preliminary estimates and scenario exploration. While we strive for accuracy, we recommend consulting qualified engineers for final system design, safety decisions, and regulatory compliance in your specific application.
How to Use This Calculator
Key Parameters Explained
Storage Pressure
- Typical Values: 350-700 bar for gaseous storage
- Impact: Higher pressure increases storage density but requires stronger tanks
- Safety Limit: Never exceed 90% of tank rated pressure
Temperature Considerations
- Standard Range: -40°C to 85°C (most composite tanks)
- Thermal Effects: Temperature affects gas density and tank safety
- Note: Calculations account for thermal expansion
Example Calculation
Typical Storage Scenario
Pressure:
350 bar
Temperature:
20°C
Volume:
10 m³
Result:
≈ 241.5 kg H2
Optimization Tips
- Composite tanks typically operate at 350-700 bar pressure
- Lower temperatures increase storage density but require cooling
- Real gas behavior is accounted for via compressibility factor (Z)
- Always include 10% safety margin in final calculations
Safety Notes
Avoid temperature swings >50°C/hour to prevent tank stress
Maintain pressure below 90% of tank rating
Technical Notes
- Calculations use modified Benedict-Webb-Rubin equation for hydrogen
- Valid for pressures 1-700 bar and temperatures -50°C to 100°C
- Includes real gas behavior through compressibility factor
- Assumes pure hydrogen gas composition
