Your challenges, our expertise

Hydrogen production depends both on the electricity source and the control and management systems of the installation to meet the main challenges of the renewable energy sector:

  • Downscaling of electrolysers to multi-megawatt facilities
  • Taking into account the intermittencies linked to renewable energies
  • Performance gains with comprehensive concepts of efficiency, safety and total cost of ownership reduction
  • Multiplication of distributed generation units that must be compatible with electrical networks

Our expertise: electrification and supervision of green hydrogen production by water electrolysis

  • Electrical distribution management
  • Power conversion associated with the electrolyser
  • Cooling management
  • Integration with the energy management system
  • Supervision of the electrolysis process: monitoring the entire production process up to the electrolyser
  • Project management and services
