  • 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 from Renewable Power
    • July 14. 2021

    Hydrogen is an energy carrier and can be produced from a wide variety of sources. Its market is well established, with global demand currently standing at around 8–10 exajoules (EJ), most of which is consumed in the chemical sector. At present, roughly 95% of worldwide hydrogen production comes from fossil fuels. Hydrogen from renewables can be produced through various pathways, with the most esta...

  • 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...

  • 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 ...

  • 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.

  • 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.
