Hydrogen Testing

As a multidisciplinary testing and research facility, Powertech has a leadership role in the development of clean energy solutions, such as hydrogen fuels and storage. To support technology advances Powertech provides services in hydrogen testing, certification and prototype development.

Our team of professional engineers and technologists have over 30 years of related experience, and they are committed to the development of hydrogen standards. Currently, Powertech chairs the draft ISO 15869 standard for hydrogen vehicle tanks, the ISO 17268 standard for hydrogen fueling connectors, the U.S. CSA HGV2 draft standard for hydrogen tanks, and the U.S. CSA HGV3.1 draft standard for hydrogen fuel system components.

Hydrogen Testing & Certification:

Powertech provides testing and certification services to all national and international standards for compressed hydrogen components and storage tanks used in vehicles, transportation, and fueling station applications.Our testing capabilities range from high pressure hydrogen gas cycling and hydraulic pressure cycling, to extreme service conditions, such as bonfire, impact, and gunfire penetration testing and the hydrogen embrittlement testing of materials. Our remote destructive test facilities allow us to perform extreme safety tests involving vehicle fires and collisions, severe penetrations, and ignition tests involving deflagration/detonation.

To support vehicle OEMs, we conduct tests on individual components including hoses, valves, pressure regulators, flowmeters, fueling connectors, tanks, etc., to all existing and draft standards, including EU No. 406/2010 (EC 79), CSA HGV3.1, SAE J2579, and the draft United Nations Global Technical Regulation for hydrogen vehicles. Powertech also conducts simulated lifetime testing of complete hydrogen vehicle fuel systems in accordance with OEM-specified lifetime endurance tests.

Hydrogen Embrittlement Evaluation:

Hydrogen Embrittlement evaluation of materials using small-scale samples can be performed up to 700 bar (70 MPa) using various test methods, including those in ISO 11114-4. Alternatively, complete designs or sub-assemblies can be tested by cycling in hydrogen gas at pressures up to 1000 bar (100 MPa). This data allows manufacturers to select materials that are safe for service in high pressure hydrogen applications.

Hydrogen Embrittlement testing is performed by our Materials, Mechanical and Metallurgy group. In addition to typical embrittlement test methods such as notched tensile and disk methods, they can prepare fracture mechanics test specimens, establish crack growth rates under various loads, and K1H values under various hydrogen pressures.

Hydrogen Component Prototype Development:

Powertech is able to reduce the costs of prototype development by identifying the critical tests that will determine the ability of a design to successfully meet the performance requirements specified by safety standards and vehicle OEMs. This understanding of the critical nature and purpose of tests comes from the years of experience in Gas Systems involving testing and the development of standards. The Materials, Mechanical and Metallurgy group at Powertech have a range of tensile and vibration test equipment, along with associated environmental chambers, to assess the ability of individual components to meet performance requirements. Similarly, the Chemistry, Materials and Inspections group at Powertech have the ability to fully characterize the performance of plastic liner materials.

Failure Analysis & Root Cause Investigations:

Powertech offers expert witness services such as failure analysis and materials testing to resolve many litigation issues relating to compressed gases, especially in incidents involving CNG or hydrogen. We are able to bring our multidisciplinary test facility to bear on virtually any incident investigation. Livio Gambone, P. Eng. has over 20 years of experience providing expert witness services in the support of litigation efforts on behalf of both defense and plaintiff's attorneys.
