Compressed Hydrogen tank mass estimation

Click For Summary
SUMMARY

The mass of a compressed hydrogen tank can be calculated using the formula: mass = density × volume, where the volume is derived from the tank's dimensions (cylindrical with hemispherical ends). For a Type IV composite tank with a polymer liner, it is reasonable to assume the liner's weight is negligible due to its non-load bearing nature. Additionally, the weight of tank valves, regulators, and pumps can be factored into the overall mass estimation, although specific formulas for these components were not provided in the discussion.

PREREQUISITES
  • Understanding of cylindrical and hemispherical geometry
  • Knowledge of composite materials, specifically Type IV tanks
  • Familiarity with density and volume calculations
  • Basic principles of pressure and its effects on tank design
NEXT STEPS
  • Research the calculation methods for composite tank design, focusing on Type IV tanks
  • Learn about the impact of pressure on material selection and tank integrity
  • Investigate the design and weight estimation of valves and regulators for gas tanks
  • Explore advanced modeling techniques for hydrogen storage systems
USEFUL FOR

Engineers, material scientists, and professionals involved in the design and analysis of hydrogen storage systems, particularly those focusing on composite tank technology.

Does anyone know how to calculate the mass of compressed hydrogen tank at certain pressure.

The tank is cylindrical with hemispherical ends.
I have pressure,radius,wall thickness and length,internal volume and density of the material.



The tank is a Type IV tank.(Composite tank with polymer liner.)Is it reasonable to assume that the polymer liner weight is neglible since it is a non-load bearing structure and just there to prevent hydrogen permeation.

Are there any formulas that calculate the weight of the tank valves and regulators and pumps as a factor of the tank weight.

Thanks for your help.

Since you know the material's density and have enough information to calculate the volume of the tank...just multiply the density times the volume to get the mass.
