Hydrogen production and usage

Specific hydrogen applications

Many applications for fuel cells:

  • Production of clean electricity
  • Emergency power supply
  • Isolated mains supply
  • Contribution to Smart grid
  • Zero emission generator
  • Shore power for ships
  • Maritime, propulsion and auxiliary applications
  • Clean mobility, Automobiles, bus, machines, rail
  • For each of these applications, the provision of DC energy to these consumers will be specific and will require the work of a specialist.

Danfoss has extensive experience in energy conversion and can support you on all of these applications.

Many different electrolyser technologies:

Danfoss' wide technological offer ensures that we are able to adapt our proposal to the constraints of your electrolyser and those of your project:

  • AC / DC thyristor rectifiers for 6 to 18 pulse architectures
  • Active and passive filters for the treatment of harmonics
  • Static compensators to compensate for reactive energy
  • Active AC / DC rectifiers with low harmonic rate for direct conversion
  • LC, LCL network filters and common mode voltage filter

Low harmonic active AC / DC / DC converters for DC conversion to suit all DC voltages and all DC voltage and current ripple requirements.
