Our Technology

Hydrogy SA will be a major actor in the field of « RES to H₂ » by using the pressurised alkaline electrolysers for their best technical and economical characteristics proven by decades of field experience, such as:

• Safe, efficient and cost saving operation.
• Adapted to fast and big load changes as well as frequent start up and shut down.
• High reactivity (short response times after input changes)
• Minimum Energy consumption. 
• Minimum maintenance and remote control operations.
• Long life cycles and low LCC’s.
• High gas purities.

Hydrogy focuses its activities on two main fields:

• Energy storage : excess renewable energy is transformed into hydrogen and stored.
• The hydrogen can later be used for multiple purposes (fuel cell, process gas etc) in fields such as:
  • mobility
  • grid regulation
  • domestic
    • And others
• Decarbonation :  oxygen instead of air is supplied to a combustion system for an efficient capture of the CO₂ in flue gas that « only » contains H₂O and CO₂.
• The captured CO₂ is then methanised by reacting with the hydrogen to produce synthetic natural gas (SNR)
