Building Hydrogen Tanks

Specification:

  1. Hydrogen Tanks volume is approximately 1 liter.
  2. Hydrogen is compressed to 8 bar.
  3. Normal operating condition (room temperature and humidity).
  4. Maximum budget is Rp500.000

Material Selection:

  Common materials used for hydrogen tanks include high-strength steel, carbon fiber reinforced polymers (CFRP), and composite materials.

Manufacturing Process:

  Prepare the chosen materials in accordance with the design specifications.
  If using metal, the manufacturing process may involve cutting, forming, and welding the steel plates.

Quality Assurance and Testing:

  Perform quality checks throughout the manufacturing process to ensure the tank meets design specifications.
  Conduct various non-destructive testing methods, such as X-ray and ultrasound, to identify any defects or weaknesses.

Surface Treatment:

  Apply appropriate coatings or treatments to enhance the tank's resistance to corrosion and improve durability.
  

Installation of Valves and Fittings:

  Integrate valves, pressure relief devices, and other necessary fittings onto the tank.
  Ensure proper sealing and connections to maintain safety and prevent leaks.
  Pressure Testing:

Subject the completed tank to rigorous pressure testing to verify its strength and integrity.

  Typically, hydrostatic or pneumatic testing methods are employed to evaluate the tank's ability to contain hydrogen gas under pressure.
  Certification and Compliance:

Seek certification from relevant regulatory bodies to ensure the tank meets safety standards and legal requirements.

  Compliance may involve adherence to codes such as ASME Section VIII or ISO 11439.

Installation and Integration:

  Install the hydrogen tank into the intended system or vehicle, considering appropriate mounting, anchoring, and connection methods.
  Ensure proper integration with associated components, such as hydrogen fuel cells or fueling systems.
