Hydrogen Electrolysers: A Comprehensive Guide to Green Hydrogen Production

Green hydrogen has emerged as a promising solution in the quest for a cleaner, more sustainable energy future. Produced by splitting water into hydrogen and oxygen through electrolysis, green hydrogen is a carbon-free energy carrier that can significantly reduce global greenhouse gas emissions. This comprehensive guide explores the role of hydrogen electrolysers in green hydrogen production, delving into the technologies that make this possible and the advanced solutions Yonder offers for efficient and reliable power conversion.


Understanding Hydrogen Electrolysers

 

Hydrogen electrolysers use electricity to split water molecules into hydrogen and oxygen. The hydrogen produced is considered "green" when the electricity used in the process comes from renewable sources like wind, solar, or hydroelectric power. Electrolysers come in different types, each suited for specific applications and varying in efficiency, operating conditions, and scale.

 

The four primary types of hydrogen electrolysers are:

 

  1. Alkaline Electrolysers are the most established and widely used electrolysers. They operate at lower costs and have a longer lifespan, but they typically have slower response times and require more space.
  2. Proton Exchange Membrane (PEM) Electrolysers: PEM electrolysers are ideal for integrating renewable energy sources and are known for their compact design and fast response times. They operate at higher efficiencies but come at a higher cost than alkaline electrolysers.
  3. Solid Oxide Electrolysers (SOEC): These high-temperature electrolysers offer the potential for greater efficiency by using heat to reduce the amount of electricity needed for hydrogen production. However, they are still in development and are not yet widely commercialized.
  4. Anion Exchange Membrane (AEM) Electrolysers: AEM electrolysers combine the benefits of alkaline and PEM technologies, offering a cost-effective solution with relatively high efficiency and flexibility in using different catalysts.
