Compressed Hydrogen Storage Tank Design

Customer requirement list :

1. Storage tank volume is approximately 1 liter.

2. Hydrogen is compressed to 8 bar of gauge pressure.

3. Normal operating condition (room temperature and humidity).

4. Output and input port for hydrogen filling and exerting.

5. Add pressure regulator for output port.

6. Maximum budget is 500.000 rupiah.

Determining hydrogen phase :

According to hydrogen phase diagram above, hydrogen at 8 bar of gauge pressure and 25 degree Celsius, is in gaseous phase.

Determining tank size :

First step is to determine the tank inner diameter : 100 mm

According to the equation above, the inner height of the tank is h = 1.000.000 / 3,14 x 50 x 50 = 127,32 mm

Tank minimum wall and head thickness :
