This free tool offers two calculators:
Useful for hydrogen storage design, fueling analysis, and thermodynamic simulations.
This tool allows you to calculate the density of hydrogen under specific pressure and temperature conditions, using the thermophysical library CoolProp for accurate real-gas behavior.
Understanding the density of hydrogen is essential for:
Designing pressurized storage systems.
Performing thermodynamic calculations.
Validating simulation results in hydrogen-based applications.
Just enter the pressure and temperature of the hydrogen, and the tool will return its density in kg/m³ — accurate even at high pressures and low temperatures, thanks to the real-gas equations used.

If you know the mass of hydrogen stored in a tank, along with its volume and temperature, this calculator allows you to estimate the internal pressure of the tank.
This is particularly useful for:
Performing mass balance calculations.
Estimating pressure after hydrogen loss or consumption over time.
Assessing storage performance in real-world applications.
Example use case: You know your storage vessel has lost 0.5 kg of hydrogen over a certain period. Enter the current mass, volume, and temperature, and the calculator will estimate the new pressure inside the tank.
This calculator uses real-gas thermodynamics (via CoolProp) to ensure accuracy in high-pressure applications.
🔍 Use it to validate experimental data or to model dynamic behaviors in hydrogen storage systems.
