Hydrogen testing: components, fuel cells & storage systems

How to get your hydrogen solutions safe, reliable, and compliant

How to get your hydrogen solutions safe, reliable, and compliant

As an innovative and flexible energy carrier, hydrogen is being used more frequently today across various sectors and industries, also offering a sustainable solution with environmental advantages. Hydrogen is for example utilised in the mobility sector, but also widely adopted in other energy-intense industrial sectors such as steel and metal processing, the electrical industry, and chemicals. These energy-intense sectors are heavily relying on low-carbon energy solutions and green hydrogen to reduce their impact on the climate and especially in mobility to achieve ambitious zero-emission targets.

However, no matter how hydrogen is used, the safety of all hydrogen components must be guaranteed.


TÜV SÜD’s multidisciplinary team of experts possesses the knowledge and experience to provide quality and safety testing services for hydrogen components, fuel cells, and storage systems. Our testing scheme is set up according to global standards and regulations and specific safety requirements. In this way, we ensure the conformity of your hydrogen components so that your products can enter national or international markets without delay.

Within our state-of-the-art hydrogen testing laboratory, we conduct various tests for industrial & energy manufacturers and vehicle component manufacturers. Our component and material testing lab for hydrogen allows us to make reliable statements on general product safety. We can also forecast the performance of components over time. For manufacturers as well as users, this means a significant plus in safety by minimising operational, occupational, and safety risks.

Furthermore, we follow a customer-focused approach and can provide individual solutions for our customers in creating tailored test and certification setups for new, innovative systems, drawing on our experience and in compliance with existing standards. This enables us to deliver quality and security with long-term benefits for your company.



We can support you along the entire product lifecycle of your hydrogen components, fuel cells and storage systems. Our team can advise you from concept and development stage, to validation, as well as qualification and certification, installation, and operational support.

Frequently asked questions (FAQs) on hydrogen testing 

  • What are the challenges for Hydrogen manufacturers and operators?

    One of the main challenges for hydrogen manufacturers and operators is to ensure the safe handling, storage, and transportation of hydrogen. Hydrogen is highly flammable and has a wide flammability range, posing safety risks if not managed properly. Therefore, rigorous testing and compliance with safety standards are critical to mitigate these risks. Developing and implementing effective safety protocols, conducting thorough testing of equipment and infrastructure confidence in hydrogen as a safe and viable energy carrier.

    Managing these challenges requires strategic planning, continuous innovation, adaptability, and collaboration with experienced hydrogen component testing experts like TÜV SÜD.

  • Who should consider hydrogen testing services?

    Hydrogen testing is relevant for numerous stakeholders, such as:

    • Hydrogen component manufacturing companies
    • Hydrogen component operators, like fuel cell station operators
    • Organisations responsible for certifying hydrogen components

    The hydrogen testing services offered by independent third-party providers like TÜV SÜD ensure that hydrogen components meet relevant safety and quality standards and requirements, leading to reliable and high-performing hydrogen products.

  • Why are hydrogen component testing services beneficial?

    Testing services are a strategic investment for hydrogen component manufacturers and operators that ensure the quality, safety, reliability, and performance of innovative hydrogen components.

    When choosing TÜV SÜD´s hydrogen testing services, you will get support from product development through material selection, qualification and design validation. Furthermore, with our comprehensive testing scheme, we ensure compliance of your hydrogen components with all relevant standards and directives and certify your products.

    Rigorous testing allows manufacturers to identify and fix defects before the products reach the market. This not only maintains the company's reputation for reliability but also prevents costly recalls and customer dissatisfaction. In addition, testing also optimises performance, streamlines certification and helps to gain access to national or international markets with your products without any delays.

  • Which hydrogen tests for metallic and non-metallic materials are offered by TÜV SÜD?

    We regularly test materials (metallic and non-metallic) regarding the following criteria:

    • H2 compatibility (SAE J2600, ISO 17268)
