Chapter 264 Hydrogen Manufacturing Method

Refueling hydrogen energy vehicles is as convenient as refueling fuel vehicles, and the speed is very fast. It does not need to be charged for several hours like a tram, and requires patience.

It can run [-] kilometers after a few minutes of refilling.

Hydrogen energy vehicles convert chemical energy into electrical energy. The energy conversion efficiency here is very high, which can reach about 80.00%.

This figure is already very high.

Hydrogen energy vehicles use hydrogen fuel cells, but they are completely different from the lithium batteries on trams, and the principle is also different.

Let’s talk about the lithium battery first. In fact, it has electricity itself, and it stores electrical energy inside. It can be taken out directly when needed.

But the hydrogen fuel cell is not like this. It does not have electricity itself, and it will generate electricity immediately when needed, which means it is equivalent to a generator.

It is to convert hydrogen into electricity and then release it.

In order to popularize hydrogen energy vehicles, the cost problem needs to be solved. Only when the cost is controlled can large-scale production and industrial production be carried out.

One of the most costly and difficult problems is how to produce hydrogen cheaply.

There are many ways to produce hydrogen, such as electrolysis of water to produce hydrogen. Many people know that water is composed of oxygen and hydrogen. As long as oxygen and hydrogen are separated from the atomic level, then we get hydrogen and oxygen. The purity of the hydrogen gas produced is very high, which can reach 90.00%.

However, there are also disadvantages, that is, the high manufacturing cost.

There is also the production of hydrogen from water gas. The specific method is to react coal or anthracite with water under certain conditions (high temperature conditions). At this time, the water has become water vapor due to the temperature.

After the reaction, carbon monoxide and hydrogen will be generated, and then the carbon monoxide will continue to react, and finally carbon dioxide will be generated, and the carbon dioxide will finally dissolve into the water, leaving only hydrogen.

In this way, hydrogen is produced, but compared with the previous method, the purity of hydrogen produced in this way is somewhat lower, which can reach 80.00%.

In addition, there are other methods to produce hydrogen, such as natural gas to produce hydrogen, such as alloy method to produce hydrogen and so on.

After thinking about it, Zhang Xingchen decided to use electrolysis of water to produce hydrogen.

First of all, in terms of materials, water can be described as inexhaustible for us, and seawater can be directly taken when electrolyzing water.

The requirements for water quality are not particularly strict.

In fact, the method of electrolyzing water to produce hydrogen is so expensive and the cost is so high, the main reason is the electricity bill.

As long as the electricity problem is solved.

"Looks like it's time to improve solar energy utilization technology." Zhang Xingchen murmured.

Now the utilization rate of solar energy has reached 60.00%, and Zhang Xingchen plans to directly increase it to 70.00% this time.

In this way, the cost of electricity will be reduced.

Now all the energy on our planet comes from the sun, in fact, even wind energy also comes from the sun.

The temperature of the two places is different, which causes the gas to flow, thus generating wind.

As time goes by, the energy on our planet will definitely become less and less. In the end, we still have to think about how to use solar energy, which is one of the solutions to energy.

After rigorous calculations, Zhang Xingchen can control the price cost of hydrogen production at one yuan, which is one yuan per cubic meter.

The cost is already very low.

The energy produced by the complete combustion of 2.5 cubic meters of hydrogen is equivalent to the energy produced by the complete combustion of one liter of gasoline.

The cubic meters mentioned here are under normal conditions, and gas compression must be carried out for future storage.

If one cubic meter is one yuan, then 2.5 cubic meters is 2.5 yuan, which is equivalent to 2.5 yuan per liter of gasoline.

Well below the price of gasoline now...

It can be said that using hydrogen is cheaper and will definitely be liked by consumers.

But what we are talking about here is the cost price... As for the price for external sales, this is still open to discussion, and the feeling of gasoline must also be considered, and the price should not be too low.

If the price is too low, then there will be no room for price reduction in the future.

To leave a way out for yourself is also to leave a way out for others.

Now that the difficulty of producing hydrogen is solved, what remains is how to store hydrogen.

In fact, there are many ways to store hydrogen, such as high-pressure storage, which is a relatively common method. The principle is very simple, that is, use high-pressure methods to compress hydrogen into a small space and store it in a closed storage tank.

Another example is the low-temperature liquid storage method. When the hydrogen is in a low-temperature environment, the hydrogen will change from a gaseous state to a liquid, so that the volume will be reduced a lot, so that more hydrogen can be stored per unit volume.

and also……

and many more.

Here Zhang Xingchen is going to use the metal storage method, which is a storage method obtained by Zhang Xingchen from the super black technology system.

Metal is a special alloy named hydrogen-absorbing alloy. Its biggest advantage is that it has a very good degree of fusion with hydrogen and can absorb a wide range of hydrogen.

A unit volume of hydrogen-absorbing alloy can absorb five thousand times the volume of hydrogen, does it sound scary?

Moreover, the cost of hydrogen-absorbing alloys is very low to manufacture, which are metals such as iron, copper, and tungsten that we see every day. What is really precious is the manufacturing method, which is the so-called formula.

This is already under Zhang Xingchen's control.

Because of the existence of hydrogen-absorbing alloys, it is very convenient whether it is to transport hydrogen or store hydrogen at hydrogen gas stations in the future.

It is also very simple to take out the hydrogen, as long as it is warmed up, it can be taken out, which is very convenient.

The reason why some things cannot be produced on a large scale has a lot to do with the cost.

The next thing that needs to be solved is the cost of hydrogen fuel cells.

Now in the production of hydrogen energy vehicles, the cost of hydrogen fuel cells has reached 60.00%. The cost is very high. It is true that hydrogen energy vehicles can be produced now, but the price of the production is very high, and it is destined not to be popularized.

To build a car, we must build a car that ordinary people can afford.

It has always been Zhang Xingchen's dream to manufacture a car with high cost performance. For this dream, Zhang Xingchen continues to work hard.

First of all, we need to understand the working principle of the hydrogen fuel cell. When the hydrogen fuel cell starts to work, the hydrogen will be sent to the negative electrode of the hydrogen fuel cell. Under the action of the catalyst, the hydrogen will be stripped of an electron, so that the hydrogen becomes into hydrogen ions, also known as protons.

The hydrogen ions in the proton state have the ability to pass through the proton exchange membrane, and after passing through the proton exchange membrane, they come to the positive electrode of the battery.
