  • How much energy does electrolysis of water use?
    • June 08. 2021

    The electrolysis of water in standard conditions requires a theoretical minimum of 237 kJ of electrical energy input to dissociate each mole of water, which is the standard Gibbs free energy of formation of water. It also requires energy to overcome the change in entropy of the reaction.

  • How does the electrolysis of water produce hydrogen gas?
    • June 08. 2021

    Water at the cathode combines with electrons from the external circuit to form hydrogen gas and negatively charged oxygen ions. The oxygen ions pass through the solid ceramic membrane and react at the anode to form oxygen gas and generate electrons for the external circuit.

  • Industrial Hydrogen Generators
    • June 18. 2021

    Produce, store and utilize hydrogen through the electrolysis of water. With the help of an electrolyzer, we can create hydrogen and oxygen from a pure water supply and electrical current. The electrolyzer's membrane and catalysts work to take advantage of an electrochemical reaction in order to separate the oxygen and hydrogen molecules of water. Hydrogen can then be utilized to power a fuel cell ...

  • Hydrogen push ignites next stage of China's energy transition
    • July 09. 2021

    The China Hydrogen Alliance predicts that by 2025, the output value of China's hydrogen energy industry will reach 1 trillion yuan ($152.6 billion) and by 2030, China's demand for hydrogen will reach 35 million tons, accounting for at least 5 percent of China's terminal energy system. By 2050, hydrogen energy will account for more than 10 percent of China's energy system, and the annual output val...

  • Hydrogen fuel
    • July 21. 2021

    Hydrogen fuel is a zero carbon fuel burned with oxygen. It can be used in fuel cells or internal combustion engines. Regarding hydrogen vehicles, hydrogen has begun to be used in commercial fuel cell vehicles, such as passenger cars, and has been used in fuel cell buses for many years. It is also used as a fuel for spacecraft propulsion. In the early 2020s, most hydrogen is produced by steam metha...

  • Hydrogen Production
    • August 05. 2021

    Hydrogen Production ZXD’s water electrolysers will help you reduce your operating costs, eliminate the need for delivered hydrogen, streamline your operations, and increase your bottom line. By producing hydrogen on-demand, they can also eliminate the need for stored hydrogen, saving valuable floor space and increasing plant safety.

  • 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...

  • 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...

  • 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...
