Sustainable safety, efficiency and quality for the energy transition

Sustainable safety, efficiency and quality for the energy transition


A fuel cell can be described as an electrochemical cell that converts the chemical energy of a fuel (hydrogen) into electricity. Safe, functional and efficient fuel-cell systems and the pertinent hydrogen infrastructure, such as electrolysers and hydrogen refueling stations (HRS), play a critical role in the successful process of transition to a sustainable energy supply. The bandwidth of today’s portable and stationary fuel-cell systems extends from small-scale applications in the watt range to large-sized field installations and decentralised energy supply delivering many megawatts.


Our hydrogen and fuel-cell systems experts have accompanied the development of new technologies for many years. By providing comprehensive services, we support manufacturers, system integrators and owners/operators, helping them to turn innovative ideas into reality.



Our services can be divided into 3 parts:

Testing and certification

  • Testing the safety design of systems and components (e.g. with the help of FEM)
  • Hazard and risk assessment and/or review of hazard and risks assessments (e.g. FMEA, FTA, HAZOP, RAMS) to identify safety gaps
  • Homologation and certification of compressed gas components, tank systems or vehicles according to international standards (high-pressure tanks, liquid tanks etc.)
  • Testing in accredited laboratories:

    o Material analyses

    o Pressure and leak tests 

    o Life testing, durability tests

    o Ballistic tests and fire-resistance tests

  • Qualification testing of pressure equipment or the pertinent measuring and control systems according to national and international standards
  • Assessment of safety functions (sensor, logic, actuator) against the background of the performance levels (PL) or safety integrity levels (SIL, ASIL) determined in risk assessments
  • Preparation of inspection reports according to the German Industrial Safety Regulation ("Betriebssicherheitsverordnung") for regulatory approvals and licences (e.g. for hydrogen refueling stations)
  • Preparation of specifications, e.g. for the safety-related design of components and sub-assemblies (by manufacturers and owners)

Safety training for employees

  • Addressing the handling of gases, such as hydrogen, natural gas or liquid gas, or liquids such as methanol
  • Workshops and training to qualify employees according to the German Industrial Safety Regulation (qualified persons)

Other areas of support

  • Answering of questions regarding the safety-related design of components and sub-assemblies (by manufacturers and owners)
  • Assistance with drawing up technical documentation (maintenance and service plans, operating instructions) and approval-relevant documentation (e.g. hazard and risk assessment, explosion protection documents, hazard evaluations)


Your benefits at a glance
