Hydrogen energy. According to Oriental Fortune Network - Stock Bar, hydrogen energy has no practical value. The reason is that the best hydrogen production solution is that the efficiency of photovoltaic water electrolysis to produce hydrogen is too low, only 50% including transportation. is consumed, therefore the overall consumption is enormous and financially unjustified. Electrolyzed water generally refers to the product generated after electrolysis of water containing salt (such as sodium sulfate, table salt cannot be used and chlorine gas will be generated).
Does water electrolysis require a large amount of electricity?
High efficiency, low cost, difficult to promote
The photohydrolysis device is inspired by the electrolysis of water by the production of photovoltaic solar energy. Photovoltaic The production of electricity, the electrolysis of water to produce hydrogen andSolar energy storage are a renewable energy source and a very ideal development direction. However, the efficiency of water electrolysis is very low. To improve efficiency, noble metals should be used as thrust electrodes to reduce the resistance formed on the surface of the hydrogen accumulation electrode. This is very expensive and difficult to promote.
Yes. This can be understood as follows: When hydrogen is burned to produce water, a large amount of thermal energy is released, so the electrolysis of water to produce hydrogen and oxygen generally requires energy equivalent to the heat released by the combustion of hydrogen.
An extended conclusion from this fact is that before a breakthrough in low-cost hydrogen production technology (such as water photolysis), hydrogen energy is still a technology to low yield and expensive, and its applicationtion has been considerably restricted. Big restrictions
