Lithium Grid
 News: In recent years, thanks to the rapid update of electric vehicle technology and the promotion of policies, China's new energy vehicle industry has shown a “spurt” growth. As a battery component of electric vehicles , the technical level directly affects or even restricts new energy. The level of development of the automotive industry. At present, the development of the new energy automobile industry seems to have entered the “bottleneck period” when the lithium battery has difficulty in effectively breaking through the core difficulties such as poor endurance and long charging time. Hydrogen fuel cells have the advantages of long battery life and fast fuel supply, and are expected to break the bottleneck of the development of new energy automobile industry.

Hydrogen fuel cell system is a power generation system, an electrochemical reaction of hydrogen gas and oxygen gas, the water is finally discharged, the current mainstream of lithium compared battery, more environmentally friendly. According to the battery China network, the current charging mode of the lithium battery is generally 30-50 minutes, compared to the lithium battery used as the energy storage device, the hydrogen fuel cell system itself is the power generation device, supplementing the fuel - hydrogen It only takes 3-5 minutes.

Statistics show that in 2017, a total of 1,500 fuel cell commercial vehicles were sold worldwide, of which 1,272 were sold in China. Compared with China's huge market base, the number 1272 is actually a very small number. However, in 2016, the sales volume of fuel cell vehicles in the Chinese market was less than 30. It can be seen that the fuel cell commercial vehicles showed rapid growth in 2017.

It is worth noting that in 2017, the global capital market invested more than 10 billion yuan in the fuel cell industry, of which Chinese capital exceeded 9 billion yuan, including such as Xiongyi, Dayang, Sansuo, Zhongtong, etc. The investment layout has been carried out in the field of hydrogen fuel cells. The entry of social capital stems from the optimistic prospects for the development of the hydrogen fuel cell industry, but it will also provide strong support for the rapid development of the hydrogen fuel cell industry.

The development of the hydrogen fuel cell industry is quietly carried out.
In 2016, the Ministry of Industry and Information Technology planned in the “Energy Conservation and New Energy Vehicle Route” that by 2020, there will be 5,000 hydrogen fuel cell vehicles and 100 hydrogen refueling stations in the market; there will be 50,000 hydrogen fuels in 2025. The battery car is equipped with 350 hydrogen refueling stations; in 2030, the group will reach 1 million hydrogen fuel cell vehicles and 1,000 hydrogen refueling stations.

At the same time, local governments have begun to actively deploy the fuel cell industry. In September 2017, Shanghai took the lead in releasing the “Shanghai Fuel Cell Vehicle Development Plan” from the local government level. It is planned that by 2020, the hydrogen fuel cell industry chain will create 15 billion production value in Shanghai, and the hydrogen refueling station will be built 5-10. Two passenger car demonstration areas have been built, with a scale of more than 3,000 vehicles, with an output value of 100 billion by 2025 and a sales of 20,000 passenger cars. Subsequently, including Suzhou, Xi'an, Guangzhou, Wuhan, Foshan and other places have also released the hydrogen fuel cell industry development plan.

Not only domestically, the Japanese government has also made plans to put 200,000 hydrogen fuel cell vehicles and 320 hydrogen refueling stations by 2025. In 2030, it will have 800,000 hydrogen fuel cell vehicles and 900 hydrogen refueling stations. Germany mentioned in the hydrogen energy plan released in 2016 that by the end of 2018, it will invest 161 million euros to develop the hydrogen energy industry, and plans to complete 100 hydrogen refueling stations in 2023. The hydrogen fuel cell industry is valued in most countries.

The construction of basic supporting facilities such as hydrogen refueling stations is steadily advanced
The hydrogen refueling station supplies raw materials for hydrogen fuel cell vehicles. If the supporting facilities cannot keep up, it will seriously restrict the development of the fuel cell automobile industry. Statistics show that as of the end of 2017, there are 327 hydrogen refueling stations in the world, mainly in Asia, Europe and North America. Before 2015, there were only three hydrogen refueling stations in China, and by 2017, 13 hydrogen refueling stations had been put into operation. At present, there are still 20 buildings under construction in China. It is expected that this number will exceed 100 by 2019.

Fuel cell application advantages in the field of commercial vehicles are obvious
Different from the foreign car companies in the fuel cell vehicle layout from the passenger car, some domestic fuel cell companies choose to open from commercial vehicles. According to Battery China.com, Shanghai Remodeling Energy Technology Co., Ltd. launched 500 fuel cell logistics vehicles in Shanghai in 2017. The company's chairman Lin Qi revealed to the battery China network that the company chose to enter the fuel cell commercialization market from the logistics vehicle, mainly due to the following considerations: First, the commercial space is relatively flexible for the fuel cell system; Commercial vehicle operation routes are relatively fixed, fixed-point alignment, less demand for the layout density of hydrogen refueling stations; third, the use of fuel cells for urban public transportation and logistics distribution has certain promotion significance; fourth, it is hoped that through the fuel cell commercial vehicle market, Drive the construction of hydrogenation infrastructure and pave the way for the future passenger car market.

According to industry experts, the commercial advantages of automotive fuel cell technology are that it is not sensitive to vehicle load, mass ratio power density, volume ratio, power density is relatively high, and fueling time is very short (about 3-5 minutes to be able to put fuel Complementing), the cruising range and load are greatly improved, and the fuel cell system has obvious advantages in large load applications and medium and heavy commercial vehicle applications. In the rapid development of the e-commerce and logistics distribution industry, especially in the case of large-scale, ultra-large cities with greater demand for the logistics and distribution industry, and at the same time, the city's environment has higher requirements, the fuel cell logistics vehicle is A good application to fill the gap in the current long-life and high load of new energy vehicles.

Fuel cell technology industrialization challenge
As the most ideal energy-saving technology in the future, the industrialization and commercialization of fuel cell technology still faces no small challenge. According to the experts in the battery China network, the challenges facing the commercial application of fuel cell vehicles fall into the following categories:

First, the standard class. Fuel cell vehicles have the superior characteristics of long battery life, long battery life means more hydrogen, and the current hydrogen storage system of this 70Mpa hydrogen system standard needs to be broken. In the field of logistics, for end users, they are more concerned about operating costs, and the use of enterprises requires the company to strengthen technology research and development in the storage and transportation of hydrogen. At the same time, the relevant standards for fuel cell vehicles also need to be improved.

Second, the resource class. First, the construction of the hydrogen refueling station facilities, the commercial application of fuel cell vehicles is inseparable from the supporting construction of the hydrogen refueling station facilities. At this stage, the hydrogen refueling station has great pressure on both approval and land use. Second, the auto parts of fuel cell systems are self-contained, and the independent development and localization of key components of fuel cell systems is a key path to reduce costs. This piece needs strong support from supply chain and component manufacturers. The third is policy-oriented market pressure. The current new energy vehicle market is a subsidy-driven market. After no subsidies or subsidies have subsided, this pressure must also be affordable, and there must be solutions.

Third, cognitive classes. First, the over-interpretation related to hydrogen safety. For a long time, due to the public's lack of sufficient understanding of hydrogen energy, there are still doubts about the safety of hydrogen fuel cell vehicles. This is also a major factor in the hydrogen fuel cell vehicle industry that is currently difficult to develop rapidly. The second is the social science of fuel cell technology. Although the fuel cell is also called "battery", it is different from the energy storage battery. It is actually a power generation device, and its energy is actually stored in the hydrogen storage system. Third, the diversification of global technology routes. At this stage, fuel cells are still in the development stage, and the market has not yet formed a scale. The enterprises are still not clear on the technical route. Experts believe that in the future, fuel cells need to identify 1-2 very clear technical routes in the technical route.

As a newcomer to the new energy automobile industry, fuel cell vehicles still have a long way to go in technology research and development, supporting facilities construction and large-scale commercial applications. Faced with the above challenges, enterprises, governments and society need to participate together to promote the development of the fuel cell vehicle industry.
