Carbon neutral cannot be realized simply by increasing electric vehicles

Chairman Akio Toyoda of the Japan Automobile Industry Association (Self -Kokai), that is, President Akio Toyota of Toyota Motor, answered the reporter's question at an online round -table conference held on December 17, 2020.And the content of "realization of carbon nector" was widely reported in various media.

I think Toyota's message can be organized into two major points.

The incorrect perception that "electrification = EV" should be correct

A lot of media is confused with "EV" in the 2030s, such as the ban on the sale of new gasoline cars in the 2030s, which was announced one after another by the Japanese government and Tokyo.is.

First, the EVSMART blog agrees for the purpose of correcting the wrong perception of "electrification".

However, as the message of Chairman Toyota, it can be read that "electrification should also be included in the eV, and that it should not be further incited by EVs", but that is a little different., "Hybrid cars are gasoline cars and it is incorrect to confuse them with electrification."

Of course, the technology of hybrid vehicles with excellent fuel efficiency is important, and the current situation in Japan, where many more high -blid cars are selected compared to ordinary engine vehicles, is wonderful.

However, on the premise of the world and Japan's major goals in the world of realizing carbon neutral in 2050, hybrid cars that only use gasoline as energy sources are insufficient.The reason is that hybrid vehicles cannot be "low -carbon" but cannot be "debric -removal".

Carbon neutral is difficult to achieve unless the national energy policy changes

In Japan, the power generation ratio in Japan pointed out that the thermal power generation of petroleum, natural gas, and coal was about 77 %.It is a view that it is difficult for Japan to achieve carbon neutral in 2050 if the energy policy does not change drastically (only by electrification of automobiles).

I can agree with this point.Even if the current power generation ratio is the current power, electric vehicles have better energy efficiency from the same amount of oil than engine vehicles, but contributions to decalbonate are limited.Changing engine vehicles to electric vehicles will be halved if you do not proceed with the further promotion of renewable energy and promotion of renewable energy.

However, it is quite doubtful that Toyota's remarks show that they should not hurry only for electric vehicles.

While many countries and manufacturers around the world are going to the "electric vehicle shift", the challenge of power generation in Japan is not an exemption from Japanese automakers to "prioritize further spread of hybrid vehicles over electric vehicles".Yes.Mr. Toyota mentioned that the automotive industry has increased the number of employment by 110,000 among this year's corona, so the cars made in Japan (the premise that hybrid cars are the center) is large, so it can be made because there are many CO2 emissions.When it was gone, he expressed a sense of crisis that the current automotive business model would collapse.

However, when a global market noticed the advantage of electric vehicles compared to engine cars, and the world's automobile manufacturers came out of electric vehicles that were as price and attractive as engine cars, a Japanese car manufacturer was gasoline car.What happens if you stick to a hybrid car?It is not about reducing employment, but automakers itself will be in danger of survival.

In that sense, I can agree with Toyota's comment that the automotive industry (Japanese) is at the last minute.

By the way, the online roundtable on the 17th was held by the Self -Technology Association for limited media and reporters, and the EVSMART blog could not participate.In addition, I searched for video archives and so on in writing this article, but I could not find it.When I checked with the department in charge of the Self -Kokai, there is no plan to report on the content of Toyota's remarks in the future.

In this article, "CAR WATCH" (Impress), who reported the content of Mr. Toyota's most detailed, "Chairman Akio Toyoda," Automotive Series, "The automotive industry is at the last minute."

What happens if all 4 million passenger cars are made into EVs?

Chairman Toyota has an example, saying, "What kind of situation will it happen if all 4 million passenger cars are made into EV?"There is no objection to the estimation number, but what about changing the perspective?Let's consider that.

There is no objection that if all engine vehicles are EVs, the amount of power required for charging will increase by 10-15 % compared to the current power generation capacity.Even on the EVSMART blog, "Is it meaningless because electric vehicles use thermal power power?In the article, it shows an estimate that the power increases by about 10 % when all passenger cars become EVs.(Postscript: As you pointed out in the comments, "increase by 10-15 %" is not a "4 million units" of the annual sales volume, but it seems to be an estimate when all Japanese passenger cars are replaced).

Also, in 2017, when I went to the Japan EV Club, "Travel around Tohoku (EV Super Seven)", when electric vehicles became widespread in the world, the number of predictions in 2030 was the world.The total demand for power increases about 1.5 %.In addition, if all Japanese cars, including commercial large vehicles, become EVs, the necessary power is 16.2 % of Japan's total power (both estimated by the Japanese EV Club Representative Director Tate Uchinata).I have created materials that offer almost the same amount of energy generated and presented them in various places.

But I don't know why the amount of power is necessary for the "summer power demand peak".There should be evidence in this regard, so I checked with the public relations department in charge, but from Toyota Motor Corporation, "I can not answer by an individual company (also a gathering of the Self -Technology Association)", and from the Self -Technology Association.Because it was a limited roundtable, I couldn't get an answer.

Personally, it can be solved by formulating rules such as "increase the necessary electricity demand for further increase in renewable energy" or "stop charging to electric vehicles at the time of electricity".I think it is.It is the same as Mr. Toyota's view in the sense that national measures are indispensable.

It is pointed out that the cost of ordinary charging equipment at home is "10,000 to 200,000 yen" and the rapid charger is "6 million yen average", which is the cost required to make all cars EVs.

If you calculate it in an easy -to -understand manner, if the home charger is 200,000 yen, a charger will be attached to 70 million households for 14 trillion yen.In addition, a quick charger can be installed for 6 million yen, and about 160,000 units can be installed for 1 trillion yen.I feel like this is a bit excessive estimate.

If you hear 14 trillion or 37 trillion yen, you will tremble with a tremendous amount of money, but according to the Ministry of Land, Infrastructure, Transport and Tourism's "Automobile Fuel Consumption Survey", it was consumed by cars in Japan.Gasoline is 48,499,000kg.The gasoline fee is 120 yen, which is equivalent to about 5.8 trillion yen.Of course, EVs cost electricity bills, but the charger is used for a long time once installed.Even if the infrastructure costs 14 trillion yen, you can not overlook that about 6 trillion yen, which has disappeared every year, can be saved.

Rather, I feel that the charging infrastructure, especially the quick charging infrastructure, is necessary to reform various mechanisms related to power supply of high voltage high output.

A mini car is a Japanese national car.In particular, mini cars are lifelines in rural areas.We are concerned about how to make a mini car established in the tide of eliminating gasoline cars.Although it is not a estimated number, it was a point to be worried about, so I picked it up.

It is difficult to secure a space equipped with large batteries in a mini car, and there is also the merit of "price is reasonable!"I can understand that.

But that's why there is a big chance.Electric vehicles that Western manufacturers are selling one after another are luxury cars equipped with large -capacity batteries.It should have been a Japanese home art that developed and provided high -performance small cars at a low price.Furthermore, I feel that it is not very meaningful for the sailing legend of "500 km in one charge" as one of the electric vehicle users.

For example, I would like to have a Japanese manufacturer develop a mini car EV for a new car price of 1.5 million yen (about 20-30 kWh).It is a "request" that keeps shouting here and there.If you can develop an attractive light EV, a mini car that tends to be ridiculed as Galapagos may be sold in the world.

I think Toyota's remark that the Japanese automotive industry is at the last minute is true.I don't intend to deny a hybrid car with excellent fuel economy.It has been repeated in the article, such as "The statement of President Akio Toyoda in Toyota Intermediate Financial Accounting's remarks in Toyota Intermediate Financial Restrictions," which was released on November 23, "I do not understand Tesla."I would like you to take advantage of the electric car development with the charm of fighting with.
