The importance of power conversion technologies in the production of green hydrogen

The global demand for green hydrogen is high and rising fast. Some studies predict that the electrical power demand to produce green hydrogen will be 4500 GW by 2050, compared to today's (2023) electrical power demand of around 25 GW. This exponential growth will be fueled by green hydrogen, which will reduce the carbon footprint of existing industries that use hydrogen as a feedstock, and by developing novel methods for storing and transporting energy.


Our whitepaper briefly delves deep into the factors driving growth in the hydrogen market before focusing on the Power Conversion System (PCS) required for electrolysis. Some typical electrolysis plant layouts and topologies for AC-DC and DC-DC power conversion are introduced. As a global leader in power semiconductors, Infineon's comprehensive portfolio offers PCS designers a wide range of choices. The paper will conclude with an overview of Infineon's products and capabilities.

Key takeaways:

  • Infineon´s key offerings for power conversion for different electrolysis technologies
  • Factors propelling growth in the hydrogen market
  • The necessity of efficient Power Conversion Systems (PCS) for stabilizing DC current in electrolysis plants
  • The pivotal role of hydrogen electrolysis powered by renewable energy in future energy systems
  • Introduction to various electrolysis plant designs and topologies for AC-DC and DC-DC power conversion
