Testing Solutions in the Hydrogen Technology Industry

Hydrogen is the energy source of the future and is a fundamental component of the necessary transformation of energy systems.Its very high energy density and usability in bound form makes it an attractive energy carrier, however it is not unproblematic and is fairly demanding when it comes to handling it.

Mechanical materials testing requires highly accurate and specifically adapted testing technology that allows for reliable determination of material characteristic values under direct hydrogen influence, very high pressure, very low temperatures and over very long time periods.ZwickRoell provides testing solutions that comprehensively meet the high requirements of the hydrogen industry and represent an important contribution to the further development of materials and components.

Use of hydrogen

  • Hydrogen has been used in the chemical industry as a raw material or as fuel for a long time.It is also an ideal energy source for the future and is a fundamental component of the necessary transformation of energy systems.Hydrogen is very flexible and widely applicable in the industrial, transport, electricity and heat sectors.Green hydrogen produced from renewable energy contributes to the reduction of greenhouse gases and thus to climate protection.
  • As the most common element, hydrogen is available in almost unlimited quantities and can be used directly or transported and stored in gas and liquid form.Its very high energy density and usability in bound form makes it an attractive energy carrier, however it is not unproblematic and fairly demanding when it comes to handling it.
  • Hydrogen diffuses easily and quickly through solid materials due to its low density and small molecular cross-section.In the case of metallic materials, for example, this leads to hydrogen embrittlement and therefore to a strong reduction of the material strength.Mechanical materials testing is an important component of the characterization and development of new materials that have to function safely and reliably under the influence of hydrogen for the long term.

Important and safety-critical components of hydrogen technology

  • Hydrogen production (e.g. electrolyzers)
  • Hydrogen transport (e.g . pipes, valves)
  • Hydrogen storage (e.g. liquefied gas, pressure vessels)
  • Energy conversion (e.g. fuel cells)

Testing solutions in the hydrogen industry

The ZwickRoell application examples show testing solutions that comprehensively meet the high requirements of the hydrogen industry and provide an important contribution to the further development of materials and components.

Fuel cells

Fuel cells are tested for force, compression and deformation behavior and bipolar plates are tested for flexural and compressive strength.Gas diffusion layers are tested for compression behavior, electrical conductivity and gas permeability under various levels of pressure.Membranes and seals are tested for deformation and sealing performance under realistic loads.

Hydrogen Influence on Metals

Metallic materials become brittle under direct influence of hydrogen, and lose their strength.The development of new materials requires realistic testing during which the metallic material specimens and components can be characterized under the influence of, or after being subjected to hydrogen.
