Lifetime Concepts for Hydrogen Applications


  • Assessment of damage mechanisms in components; Development of corrective measures
  • Providing evidence of hydrogen brittleness
  • Selection, qualification and characterization of materials for hydrogen applications
  • Residual stress optimization to avoid cold crack formation of welding joins
  • Assistance in avoiding hydrogen brittleness in additive manufacturing processes
  • Optimization of degassing heat treatments, e.g. after galvanic coating
  • Optimization of welding and heat treatment processes
  • Development of new protective layers against hydrogen
  • Suitability of lubricants in rolling bearings, key term: “white etching cracks”
  • Support of complex development projects in the area of hydrogen technology, e.g. Power-to-Gas (P2G) and hydrogen as an energy carrier
