On July 16, the national carbon emission trading market launched online trading, which means that the "carbon neutrality" development goal has been fulfilled on time. On the way to achieve carbon neutrality, many domestic lines are moving forward simultaneously. In addition to launching the trading market, various measures are also being carried out in an orderly manner, such as attaching importance to the use of renewable energy, promoting the development of new energy vehicles, and improving traditional energy efficiency.

However, the "carbon neutrality" development path of automobile electrification has been faced with numerous criticisms. From the promotion of new energy vehicles represented by electric vehicles in China to now, traditional car executives and well-known experts both inside and outside the industry have continuously questioned whether pure electric vehicles are truly environmentally friendly. Putting aside the recycling and utilization of power lithium batteries, many people believe that coal is an important fossil fuel power generation method in China. From a full life cycle perspective, new energy electric vehicles are not able to achieve more emission reduction and environmental protection than traditional fuel vehicles. Therefore, it is determined that the electrification path of the car cannot really break the "carbon neutrality" dilemma.

Is this viewpoint really correct?

Yiou Think Tank believes that the development of automobile electrification is an important link and the only way to achieve "carbon neutrality" in the technology travel industry. It is pointed out in the upcoming 2021 Research Report on the "carbon neutrality" Development of China's Science and Technology Travel Companies that the electrification development of cars will not only contribute to the carbon neutrality development of car companies themselves, but also play a key role in reducing carbon emissions in the entire energy industry.

Electrification path to achieve "carbon neutrality" is not a false proposition

Although electric vehicles can achieve zero carbon emissions in the use process, from the perspective of carbon emissions throughout the life cycle of the vehicle, if the electricity used for the production and supply of electric vehicles is not from clean energy, its carbon emissions are even higher than that of traditional fuel vehicles - is it a false proposition to achieve "carbon neutrality" through electrification?

A study conducted by Tsinghua University found that when the proportion of coal-fired power generation to total power generation reaches 86%, the carbon emissions generated by electric vehicles throughout their entire life cycle are consistent with those generated by fuel powered vehicles. This also means that when the proportion of coal-fired power generation is less than 86%, the carbon emissions brought by electric vehicles are lower than those brought by fuel vehicles.

In 2020, the proportion of coal power generation in China will be about 60%, which is in fact much lower than the critical threshold of 86%. Yiou Think Tank believes that with the promotion of the strategic goal of "carbon neutrality", the proportion of coal power will continue to decline in the future, while the proportion of clean energy power generation will rise. At that time, the carbon emission reduction advantages of electric vehicles compared with traditional fuel vehicles will also be more obvious.

Although the carbon trading market, which was fully launched on July 16th, did not include the transportation sector, the pressure of China's "dual point policy" is enough to accelerate the electrification transformation of traditional car companies.

On July 22nd, Mercedes Benz announced that it would prepare for full pure electrification by 2030 in markets where conditions permit.

Previously, many traditional car companies, such as Mercedes Benz, announced their electrification implementation nodes to the public. Whether under the pressure of the "dual point policy" or out of the company's long-term development, these actions by car companies also confirmed the correctness of the electrification development path.

The path of electrification will assist in the "decarbonization" transformation of energy structure

With the development of "carbon neutrality" and the promotion of energy structure adjustment in China, the use of clean energy such as wind energy and solar energy will gradually increase.

With the increasing proportion of wind and solar energy in the power structure, their arbitrariness and volatility will lead to insufficient regulation capacity and frequency stability of the power grid. If China wants to use this type of energy for a long time, it must adjust its randomness and volatility characteristics: for example, when wind and solar power generation capacity is surplus, electricity storage must be carried out; When wind and solar power generation capacity is insufficient, timely replenishment is carried out through stored electrical energy.

As a tool for adjustable load and energy storage, the V2G coordination between electric vehicles and the power grid will be particularly important.

Yiou Think Tank believes that electric vehicles can serve as an important tool for regulating energy stability in the future - storage appliances.

In 2020, China consumed approximately 20 billion kilowatt hours of electricity per day.

At present, the battery capacity of mainstream electric vehicles is approximately 50-70 kilowatt hours.

Therefore, when the number of electric vehicles on the Chinese market reaches over 300 million, electric vehicles can store approximately 15-21 billion kilowatt hours - equivalent to the total electricity consumption in a day in China.

Typically, electric vehicles are parked 90% of the time. If electric vehicles are connected to the power grid for discharge (V2G) while stationary, it is sufficient to solve the problems of randomness and volatility in the use of clean energy.

At present, multiple domestic companies have begun to work on V2G solutions, and in the future, they will develop V2G implementation methods that can meet the long-term wishes of electric vehicle users.

Yiou Think Tank believes that in the future, electric vehicles will play the role of virtual power plants to help China's entire energy system achieve carbon reduction.

Conclusion

China's electrification development path has been going on for more than 10 years, and with the formulation and further promotion of the strategic goal of "carbon neutrality", China will be more committed to this electrification development path. In the future, China's energy structure will undergo revolutionary changes, among which electric vehicles will play a crucial role.
