  • Composition of Water Electrolysis Hydrogen Production System
    • October 12. 2021

    Hydrogen production by water electrolysis is a technology that decomposes water to produce hydrogen and oxygen under the action of direct current. It follows Faraday's law of electrolysis. Under the action of direct current, water is decomposed into one part hydrogen and 1/2 part oxygen.   Water Charging System The raw water first enters the demineralized water preparation device, and after t...

  • Alkaline Water Electrolysis
    • October 05. 2021

    The alkaline electrolyzer uses 30% wt KOH solution or 25% wt NaOH solution as electrolyte. The DC current density is 2000A/m2~4000A/m2, the working temperature is generally maintained at 80°C~90°C,and the working pressure is within 3.2MPa. It also needs to ensure equal pressure operation. Structurally,the electrolytic cell uses a permeable membrane, such as asbestos, polyphenylene sulfide. The ele...

  • TEN QUESTIONS AND ANSWERS ABOUT GREEN HYDROGEN
    • August 27. 2021

    It is light and storable, and its only by-product is water. Do you still have questions about green hydrogen's potential and its role in energy transition? We have all the answers for the things that are still on your mind. Read on! 1. Is hydrogen a source of energy? No. Unlike sunlight, wind and water, hydrogen is not a primary energy source. It is an energy vector. What does that mean? It means ...

  • Why is hydrogen liquefied?
    • August 18. 2021

    Why is hydrogen liquefied? A wide range of industries including metalworking, medical technology, electronics and food processing use liquefied gases. These gases are always supplied to customers in liquid form so that they can be stored on site for later use. That is why we deliver not only cryogenic solutions for the liquefaction of H2 but also suitable tanks for reliable and efficient storage. ...

  • How can high-purity hydrogen be produced using pressure swing adsorption?
    • August 18. 2021

    How can high-purity hydrogen be produced using pressure swing adsorption? This technology works by physically binding gas molecules to an adsorbing material. The binding force between the molecules and the adsorbent depends on a number of factors, including the type of gas. This binding process creates a separation effect. Unlike carbon monoxide (CO), carbon dioxide (CO2) and nitrogen (N2), highly...

  • Why are hydrogen technologies in such high demand right now?
    • August 18. 2021

    Why are hydrogen technologies in such high demand right now? Hydrogen can smooth the transition to a more sustainable energy economy. Not only can H2 be used as a zero-emission fuel for trains, buses, trucks, automobiles and ships, but also as a feedstock for various industries including chemistry, refining and steel making. In addition, hydrogen can provide a source of energy and heat for buildin...

  • What is the difference between gray, blue and green hydrogen?
    • August 18. 2021

    What is the difference between gray, blue and green hydrogen? Gray hydrogen is obtained from fossil fuels. Steam reformers are used to convert natural gas, for instance, by means of steam addition. The resulting hydrogen-rich synthesis gas is then further processed. During the gray H2 generation process, the carbon dioxide (CO2) by-product escapes into the atmosphere. By contrast, with blue hydrog...

  • Renewable Energy
    • August 05. 2021

    Renewable Energy The growing demand for power and the global interest in reducing CO2 emissions has stimulated an unprecedented implementation of renewable sources of energy. However, intermittent power disruptions are common when dealing with renewable resources. Energy storage eases intermittent power disruptions by storing excess power generated by renewable resources at times of low demand and...
