Efficient electrolysis through comprehensive power conversion solutions
Green hydrogen represents one of the most promising pathways toward a sustainable, low-carbon energy future. Produced through electrolysis powered by renewable energy sources such as wind and solar, green hydrogen is generated in a CO₂-neutral manner - making it a cornerstone of the global clean energy transition. The industrial hydrogen supply market is a significant global business, and electrical power demand for green hydrogen production is projected to reach up to 4,500 GW in the coming decades. Infineon Technologies is well-positioned to support this massive energy shift with proven, high-performance semiconductor solutions.
What is green hydrogen electrolysis?
Green hydrogen is produced through electrolysis - a process that uses electrical power, drawn either from the grid or directly from renewable energy sources such as wind turbines, to split water into hydrogen and oxygen. This clean production process is central to global decarbonization strategies, and efficient power conversion electronics are key to making it commercially viable.
Benefits:
- Produced in a CO2-neutral manner
- Electrolysis processes
- Renewable energies
- "Green” hydrogen
- Use of downstream current converter
- Useful in high-power applications
