hydrogen energy

Hydrogen energy is the chemical energy released by the chemical reaction between hydrogen and oxygen. It is a secondary clean energy source with abundant resources, high calorific value, and good combustion performance. The hydrogen energy industry is a new energy system that includes several main links such as hydrogen production, hydrogen storage, hydrogen transmission, and hydrogen consumption. The small rocket device in this exhibit is a physical example of the "hydrogen use" process of hydrogen energy. Its principle is that the device uses hydrogen as fuel, and hydrogen and oxygen undergo oxidation and combustion reactions, releasing the stored chemical energy of hydrogen and converting it into heat energy. The high temperature causes the gas volume to rapidly expand, thereby driving the small rocket to take off.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Direct electrolysis of seawater without desalination for hydrogen production is a groundbreaking innovative technology in the hydrogen production process of the hydrogen energy industry. Seawater contains 92 chemical elements, and impurities can corrode electrolysis devices, damage catalytic components, and release toxic chlorine gas during the electrolysis process. The team led by Academician Xie Heping from Shenzhen University/Sichuan University has, for the first time, established a new principle and technology for in-situ direct electrolysis hydrogen production from seawater without desalination driven by phase transition migration, combining physical mechanics with electrochemistry. This has solved the half century problem of direct electrolysis hydrogen production from seawater. Based on this theory, our salt lake water, wastewater, and mineral water can be used to produce hydrogen, which is like opening the door to low costs and making the large-scale application of energy possible.
