212.54 liters
≈ 11 buckets
How to Use This Calculator
- Enter Hydrogen Mass (kg), Storage Pressure (bar), and Temperature (°C).
- Set Tank Type.
- Review the Tank Volume (liters) result.
- Use Tank Weight (empty) (kg) and Energy Content (kWh) to inform your decision.
- Use the chart to visualize the results and explore different scenarios by adjusting inputs.
How the result changes with Hydrogen Mass (kg)
| Hydrogen Mass (kg) | Tank Volume |
|---|---|
| 1,000 | 42,508.09 liters |
| 3,500 | 148,778.33 liters |
| 6,500 | 276,302.61 liters |
| 9,000 | 382,572.85 liters |
What each input means
- Hydrogen Mass (kg)
- Amount of hydrogen to store in kilograms.
- Storage Pressure (bar)
- Tank operating pressure. Common: 350 bar (vehicles), 700 bar (passenger cars).
- Temperature (°C)
- Ambient or operating temperature in Celsius.
- Tank Type
- 1 = Type I (steel), 2 = Type III (aluminum/composite), 3 = Type IV (carbon fiber).
What each result means
- Gravimetric Density
- Weight percentage of hydrogen relative to total system weight.
