世紀失敗品：氫能源車

Hello everyone, I'm Terry. Every once in a while, I get a lot of questions from friends and netizens asking me why I'm so sure that electric cars are the future. Or asking me what do you think about cars? The main reason why people have this question is because of the news media's reporting. The media's favorite way to cover the surface is to put some very exaggerated titles. For example, this article says that Toyota's electric car will be the killer of electric cars in the future. When I was a kid, I would see these useless news and think that wow, there are so many high-tech cars in the world. Maybe I would think that in 5 to 10 years, cars will fly.

So I decided to make a video today to share with you why the future of light vehicles is not a big deal. It is a technology without a future on a home car. In the near future, there will be no more people to buy it.

You must be wondering, since there is no future, why are Toyota and other car manufacturers still working hard to promote and develop a technology without a future? I will share with you in today's video If you like videos like this, remember to give me a thumbs up Because you know, making a video like this requires a lot of time to do research Your one like is the biggest support to my channel

Before we learn why hydrogen-powered cars are a failed product, we need to understand how hydrogen-powered cars are launched. Traditional cars use internal combustion engines, which is also what you often hear about ICE cars. ICE is the abbreviation for internal combustion engine.

The internal combustion engine will burn oil or diesel to generate power. The engine is mixed with fuel and air, and then burned to convert into mechanical energy, and then drive the car forward. During the burning process, a large amount of carbon dioxide and other harmful gases will be produced. So this is why traditional cars are not environmentally friendly.

Fuel Cell

from electric energy to kinetic energy. That is to say, fuel will combine the oxygen from the car and the oxygen from the car into chemical energy, which is then converted into electric energy, and then converted into kinetic energy through the motor. Where does this oxygen come from? There are many ways to make oxygen. The most common is to use steam to

This is also the way that 95% of the world's green energy is produced. Its principle is to generate green energy by heating natural gas and steam to cause fossil fuel to be re-organized. In the process of heating, not only will carbon dioxide be produced, but also will cause pollution to the environment.

This whole set of industrial production of hydrogen equipment and recharging machines are currently very expensive And in the end, you still have to use natural gas fuel and not the so-called renewable energy Of course, if you know some basic chemistry, you should know that the way to produce natural gas is not just SMR The other most common way is to use electric current We can use electricity to divide water into hydrogen and oxygen so that we don't have to burn natural gas to produce carbon dioxide

And this electricity can also be obtained from renewable energy But the process of making hydrogen in this electrolytic water is very power-consuming It takes a lot of electricity to divide water into hydrogen and oxygen So we can summarize If you want to use hydrogen-powered cars to generate kinetic energy First of all, we need to use electricity to convert water into hydrogen Then through fuel batteries, hydrogen from chemical energy to electrical energy Then through the motor

and then convert the electricity into kinetic energy to move the car. You can guess why the energy efficiency of a hydrogen-powered car is so low. Because we have to convert the electricity into hydrogen first, and then convert it back to electricity. The process of this process is called energy vector transition. Suppose we have 100 watts of electricity at the beginning. First, hydrogen is produced through the electrolytic water. This process has only 75% efficiency. So when it is converted into hydrogen, there is only 75 watts of energy left.

Then the hydrogen is compressed, frozen, and processed in the factory. After that, it can be re-examined. In this process, 10% will be lost. The remaining 65 watts of energy

Then when hydrogen-powered vehicles like Toyota Marui's fuel-powered batteries are converted into electricity, the energy will be wasted. Finally, only 40 watts of electricity is left. Then the energy needs to be converted into kinetic energy by motor. This process has a efficiency of 95%. So from the beginning of 100 watts of electricity, it will eventually be converted into kinetic energy. Only 38 watts of electricity is left.

That is to say, only 38% of the energy efficiency Compared to our current gasoline car Gasoline cars are famous for having very low energy efficiency Generally about 25% to 35% So in theory, hydrogen cars are indeed a little better than gasoline cars as of now As for electric cars Because electric cars are directly used to convert the battery power into power through the motor

So electric cars have about 80% of the energy efficiency When you compare the three You can see that one of the reasons why new energy vehicles do not have a future is that the energy efficiency is too low If the energy efficiency is only a little better than a fuel car But consumers may have to pay twice the price to buy a new energy car Toyota Mirai is almost $50,000 in the United States The price is twice as much as Corolla Who would want to buy Mirai

If the gas tank is cheaper than the gas tank, there may be a market because the cost of holding it has become lower. Let's look at the California Cupertino 2.0 gas tank. Now 1kg of gas is $36. The gas tank loaded by Toyota Mirai can add a total of 5.6kg of gas. So if you fill the gas tank, you need to spend $201.6. Then the official figure given by Mirai is that the gas tank can run 400 miles, which means that the price of every 1 mile is $0.5.

The latest Toyota Corolla has a 35 MPG, which means that the oil can run 35 miles per gallon. The price of Cupertino is now $4.2 per gallon, which means that the price of Corolla per gallon is $0.12. So for consumers, the cost of adding hydrogen is 4 times the cost of adding gasoline, which is 14 times the cost of charging a Tesla electric car.

Cars are expensive and cost more per kilometer. If you're honest, you're rich. I like cars that spray water. There are more than 1,000 gas stations around the world. There are only less than 50 in the United States. 90% of them are concentrated in California. If you're not from California, you can only stop at your car's garage to buy a gas station. Or you can buy a gas station online. I don't know how to get gas into the car.

Of course, if you are rich and you live in California, it should not be too difficult to get a car. But if you want to go out of the country, you can't get a car in other states. Will there be more gas stations in the future? I originally planned to build 48 gas stations in California, but now they are all cancelled. Even if the California government gives them $40 million, they don't want it. And not only California, but also the UK has slowly closed a lot of gas stations because there is no market.

In this way, green energy vehicles can be popularized

Currently, we are going to build a gas station. According to the budget of the Department of Energy in the United States, the cost is about $2 million. The traditional gas station is about $450,000. The charging station is about $50,000 to $100,000. So it's not just a question of whether consumers have money. It's that at present, you can only buy a completely useless thing. This is why it is very obvious that the future will be the electric car market.

The cost of building a power station is much lower than the cost of building a gas station and the gas stations that are now available. Now, most of the people in the world who live and buy cars have basic facilities for the power grid. You can charge it at home. In contrast, gas is very expensive because of transportation and storage. It must be stored and transported in a high-pressure or liquid form. You need to use special containers and管

Of course, the technology of hydrogen-powered energy generation is not completely meaningless.

In the industry, there are actually many other mature uses. Like many factory engines, trucks are all used for hydrogen. And some European trains are also used for hydrogen energy. But in the area of home vehicles, only electric vehicles make sense. And I believe that the technology of batteries will only get better and better. It is even possible that fuel batteries will be eliminated in the future.

At least in the next 10 years I don't see any positive growth in home-used cars Since I know that the commercial optimization of home-used cars is not feasible Why do Japanese car manufacturers like Toyota still invest a lot of money in research and development of cars? To be honest, I think the reason is actually very sad It's hard to say that it's a mixed story Then let the company's shareholders and investors continue to hold their hopes Now the facts have proven that traditional cars have to be transformed into electric cars This process is really difficult

And it's too late to do this now We can see from GM, Ford, German Ford vehicles The current strategy can be seen They are now in a very awkward situation If you want to completely transform Put all R&D on the electric car They will have at least three to five years of transition period Is completely not making money Because now every electric car is losing money The more you sell, the more you lose But if you don't do that They know that after three or five years Business will start to go down

So now it's up to the fuel cars that are still available to sell to maintain their livelihood. But they can't invest in electric vehicles with full effort. Because if they do, the financial report will be very ugly. The stock will be in a bad spot. So now we can only try to persuade that electric vehicles have no market. And then we have to reduce the investment in electric vehicles' production and development.

I think it's actually a deeper and deeper pit These CEOs and managers only care about their own stocks and short-term interests Toyota is the same They know they have been pulled apart by Tesla and Chinese electric vehicles Corolla used to be the best selling car in the world 22 years No car has beaten them in 22 years The result is now Model Y or a pure electric car I think this is a big blow to a traditional car factory with high self-esteem They can't see themselves chasing China and Tesla

So in order to keep investors and shareholders hopeful, what they can do is to keep telling the media about new technologies and technologies that are the future of electric vehicles. If you can't make something, you can't compare to others. Of course, the only thing you can do is to draw a picture and tell a story, like me. This article is a very typical example. It says that the Toyota's gas engine will be the end of electric vehicles. If you read this article carefully, you will know how stupid it is.
