Tank validation testing

Hydrogen tank validation testing is a critical process in ensuring the safety and performance of hydrogen storage systems. Hydrogen tanks are utilized in various applications, including fuel cell vehicles, energy storage, and industrial processes. The validation testing involves subjecting these tanks to rigorous evaluations to confirm their compliance with industry standards and regulations.

Tank validation testing

The primary objective of hydrogen tank validation testing is to verify the structural integrity, durability, and reliability of the tanks under extreme conditions. These tests are designed to simulate real-world scenarios and potential hazards, ensuring that the tanks can withstand the demanding environments they may encounter during normal operation or in the event of accidents or emergencies.

Hydrogen tank validation testing is crucial to mitigate the risks associated with hydrogen storage, as hydrogen is a highly flammable and potentially hazardous gas. Ensuring the integrity of the tanks is essential to prevent leaks or ruptures that could lead to accidents, explosions, or fires. Compliance with industry standards and regulations, such as those established by organizations like the International Organization for Standardization (ISO) and regulatory agencies, is essential to guarantee the safe use of hydrogen storage systems. 

  • Batch testing

Batch testing

Batch testing is a quality control process that involves testing multiple samples from a production batch to ensure consistency and compliance with standards and specifications. In the tank validation testing market 0,5% of a batch of 200 tanks is required to be tested. 

Cycle test

Hydro cyclic tests are preformed to simulate the typical life of an object. During the preformed test on a Hydrogen storage tank, the tank Is filled with a fluid and pressurized, followed by an emptying phase representing gas consumption. This cycle is repeated several thousand times to simulate the life of the tank. During these cycling, various parameters can be monitored, such as temperature and deformation of the tanks as well the possible leakage, to evaluate their long-term performance.

Burst test

Hydro burst tests are destructive tests and performed to validate the object calculated safety factor. The tests are performed with a fluid, usually water. This test is often performed as a pre-production test to meet safety and quality standards. Often the burst test is preformed periodically on produced parts, for example, 0,5 % of the total batch size is burst tested. With a Hydro burst test the object will be filled with water, the pressure in the object is slowly increased till object burst. Steady pressure build is required to ensure reliable analyzing.

Leak test

Leak testing is a test preformed to determine hydrogen leakage, the test is performed by filling the object with Hydrogen at a certain pressure and for a certain period of time. Resato can deliver the needed test equipment to perform this test in a safe and controlled environment. Hydrogen recycling can be part of the configuration, to maintain focus on OPEX & green footprint. Test can be in the range of single tests up to cyclic testing as per for example GTR No. 13-2.
