Filtration solutions for the use of green hydrogen

Protective filtration for gas engines, turbines, compressors, fuel cells and hydrogen filling stations

The requirements for the filtration of green hydrogen as a gas or in liquid state, as well as of e-fuels synthesised from green hydrogen, are extremely demanding. High pressures, low temperatures and sometimes hazardous properties (e.g. in the case of ammonia) of these media require comprehensive knowledge of these operating conditions, coupled with experience in the protection of combustion engines, turbines and compressors. 

  • Protection of injection systems, moving parts and sealing systems
  • Suitable materials for high pressures and low temperatures
  • Corrosion and embrittlement resistant materials
  • Specialised sealing materials and concepts
  • Experience in the filtration of hydrogen, methane, mathanol and ammonia
