Why can't hydroelectric power be combined with electrolyzed water to react with hydrogen gas?

Not necessarily. There are several basic requirements for electrolyzed water:

1. Pure water, no salt-containing substances, otherwise the hydrogen and oxygen coming out at the beginning may not be hydrogen and oxygen

2, add an appropriate amount of NaOH

; 3, be sure to use direct current, the voltage is above 6V, generally it can be used 12V, the effect is better. The larger the current, the better the effect, but the larger the current, the easier it is to generate heat. If shorted into water, the power transformer will burn out.

4. Keep the positive and negative poles of the power supply apart.

5. Pay attention to fire prevention and explosion protection.

The problem of water electrolysis. to produce oxygen and hydrogen

Basically, hydrogen is not the main form of energy in modern society, and there are not many places to use it. When the cost is high, few people naturally use it. Regarding hydropower, on the one hand, the power transmission method is relatively mature and inexpensive. On the other hand, hydroelectric plants have more efficient energy storage measures during peak periods: when energy consumption is low, simply use the remaining electricity to pump water. But this does not mean that the production of hydrogen by water electrolysis has no application: as an energy source with the same energy as oil, high-density substances can be used as clean energy for replace oil in places. where electricity is not suitable, such asrockets, planes, ships, etc., in addition, as an intermediate substance for energy storage, wind energy and photovoltaic energy are used to electrolyze water to produce hydrogen, which passes then in a gas turbine. Power generation can effectively solve the problem of integrating a new energy network. The problem with liquid hydrogen is that there is currently no particularly efficient and safe storage method. Large-scale storage still relies on low temperature and high pressure, which is not only expensive but also. also dangerous. Its use in rocket engines is still acceptable. It is unacceptable for civil and commercial use. As a solution, solid-state storage of metal hydrides has sweet dreams and a cruel reality. It still belongs to the category of rare metals, and it is far from possiblee to have safe and efficient storage in the future, associated with wind energy. photovoltaic and electrical energy provided by nuclear energy have declined considerably, and it is quite possible that hydrogen energy will replace oil energy in some regions.

Since the “water and hydrogen engine” needs to electrolyze water, convert it into oxygen and hydrogen, and then convert it into electricity, why not use electricity directly? What to do with rotting water?

This idea is very bold and creative, but unfortunately it doesn't work. The reasons are:

1. The vehicle's power supply is charged after the car engine drives the generator to produce electricity, and then used to electrolyze water. After several repetitions, a lot of energy will definitely be lost. which is not economically reasonable. It is better to use the dir engineectly.

2. If the hydrogen is produced by electrolysis and supplied to the engine, then you need to add a hydrogen energy engine, which will significantly increase the cost, and it is not worth it because the hydrogen produced is very small.

3. Electrolyzed water still consumes a lot of energy today. The power supply capacity of your car is limited and cannot meet the needs.

To talk about something else, current hydrogen-powered vehicles primarily use by-product hydrogen from other plants. If it is specially prepared, it has no economic value. It is also necessary to develop new efficient catalysts and then use our It is more practical to electrolyze water using energy sources that we currently cannot use directly (such as solar energy in uninhabited deserts, oceans and other places).

Yes, water is a composed very stable, so it's a scam.

Currently, there is no stable and inexpensive catalyst for electrolyzing water. The common commercial catalyst is iridium dioxide, a precious and very expensive metal. Currently available commercially are hydrogen fuel cells, in which hydrogen and oxygen are placed at both ends of the anode and cathode, respectively. Hydrogen protons enter the holes in the proton exchange membrane (PEM) and combine with oxygen molecules, as well as redox. The reaction occurs under the action of the catalyst and the electrons stuck outside the membrane must bypass both ends of the electrode plate, thereby generating current to drive the motor.
