The future of new energy has arrived: Toyota Mirai? Just like its name, Toyota Mirai is an epoch-making new energy vehicle facing the future, which represents the future direction of automobile energy development. Mirai adopts hydrogen fuel cell, which is a set of power generation device that directly converts the chemical energy contained in hydrogen and oxygen into electric energy through electrochemical reaction.
However, the manufacture and storage of hydrogen, the life and performance of the stack, the materials of anode, proton exchange membrane and catalyst, and the durability and reliability of the system are all difficulties. It is precisely because of the difficulty that Mirai's mass production is so admirable. There are two hydrogen cylinders made of carbon fiber in Mirai, with the maximum volume of 122.4L, which can store 5kg of hydrogen under the storage pressure of 70MPa.
Most of the driving force of Mirai comes directly from the fuel cell stack (i.e. power following). The lithium battery equipped in the power system is used for the temporary storage of electric energy of FCV reactor and the storage of braking recovery electric energy, and can also provide energy for the driving motor like FCV reactor. After Mirai is charged with hydrogen once, it only takes 3-5 minutes to recover the cruising range of 483km.
What is the biggest obstacle to the development of hydrogen fuel cell vehicles? Money? . The price of Mirai in Japan is 7.236 million yen (about 442,000 yuan). In addition to various tax reductions, users have to pay 4.983 million yen (about RMB304,000) to drive Mirai home. This price is available in Japan. The price of Crown 2.0T in the United States is $57,500 (about RMB390,000), and Lexus RX 450h can be bought at this price in the United States.
An official Toyota spokesman revealed that after mass production in 2020, the cost is expected to drop to 200,000 yuan, which is the price that ordinary families can barely reach, but it is still difficult. The construction of hydrogen refueling stations can not be separated from the support and investment of infrastructure in various countries. In addition, the technology of large-scale hydrogen production is not ideal and the cost is not low.
In addition, Toyota has announced that it will open 5,680 patents of hydrogen fuel cell technology worldwide, including 1970 technologies of Toyota Mirai, and the release period will be until the end of 2020. The purpose of Toyota's patent opening is to hope that the business community will accept Toyota's technical standards, form a de facto unified standard, and reduce technical risks.
Honda Clarity is close behind? Pay attention to the refined development of hydrogen fuel cell vehicles. Manufacturing? 、? Use? 、? Connect? For this idea, we are working hard to develop technologies to realize a hydrogen society. FCV released in March 20 16? Transparent fuel cell? . In order to popularize fuel cell vehicles, it is urgent to reduce costs, establish quality technology and improve infrastructure.
Honda estimates that the next generation of cars will cut CO? The emission possibilities are: (1) The electricity generated by renewable energy power generation drives small BEV to realize CO? Zero emission; Using solar energy to electrolyze water into hydrogen and oxygen to drive FCV? FCX clarity? Realize CO? Zero emissions. Honda plans to replace two-thirds of its sales with zero-emission vehicles by 2030, such as PHEV, HEV, FCV and BEV.
As the development concept of hydrogen society, the integrated hydrogen station SHS (Intelligent Hydrogen Station) is connected with the external power inverter power output 9000, centering on FCV which uses hydrogen and has the ultimate cleaning performance. Honda started basic research from 1996. After 20 years, we finally completed the research and development of FCV Clarity, SHS and Power Exporter 9000.
1. Start taxi test.
Provide more people with the opportunity to observe FCV and try to ride FCV, so that people can feel the advantages of FCV. This paper studies the influence of FCV on taxi industry, which is reflected in the subsequent development. At present, Hino Transportation (Kanagawa Prefecture) 1 vehicle, Omiya Automobile (saitama) 1 vehicle, Imperial Capital Automobile Transportation (Tokyo) 2 vehicles and Sendai Taxi (Miyagi Prefecture) 2 vehicles.
2. Strategic roadmap of hydrogen fuel cell
In Japan, according to the government-led strategic roadmap for hydrogen/fuel cells, FCV will be launched and hydrogen infrastructure will be improved. During 2025-2030, hydrogen stations will be improved and expanded independently. First, focus on four major cities, focus on improving hydrogen stations, and then promote them to second-and third-tier cities and even the whole country. Around 2025, the Japanese government will focus on this and build a social foundation for popularizing FCV.
What is the goal of the development planning stage of hydrogen energy vehicles? The first stage supports the application of FCV (about 20 15 ~ 2020).
Hydrogen infrastructure: reduce the cost of hydrogen stations and expand the number (about 20 15 ~ 2020). The second stage of hydrogen power generation: empirical test (around 20 15 ~ 2030) and official launch (around 2030 ~).
Large-scale hydrogen supply: hydrogen production from overseas raw materials, transportation test (about 20 15 ~ 2025), officially launching (about 2030 ~) the third stage of CO2-free hydrogen: CCS (carbon dioxide capture and storage, carbon capture and storage), and hydrogen production test from renewable energy (about 20 15 ~ 2030).
Due to the high construction cost and lagging development of hydrogen refueling stations, purposeful and rhythmic point-to-point transportation is the most suitable choice in the case of limited number of hydrogen refueling stations. Therefore, Japan has changed the development direction of hydrogen-powered vehicles to serve infrastructure, and manufacturing FCV trucks has become a priority.
Judging from the current number of users, it is difficult to regard hydrogen stations as profitable businesses, and it is difficult to increase the number only by subsidies. It is very important to make hydrogen stations a profitable business for realizing a hydrogen society, and Japan has turned its attention to 7- 1 1 convenience stores. From August 2065438 to August 2007, Toyota Motor Corporation of Japan signed a basic agreement on energy saving and emission reduction research in stores and logistics, which was implemented in two regions of Tokyo.
To this end, Toyota has also specially manufactured two FC trucks with refrigeration and freezing functions. The hydrogen storage capacity of FC trucks is more than 1.5 times that of MIRAI, and the daily hydrogen consumption is very large. The hydrogen energy consumed by FC trucks in 7- 1 1 convenience store is equivalent to the effect of popularizing 30 MIRAI vehicles, which virtually increases the utilization times of hydrogen infrastructure.
Introduction of Hydrogen Fuel Cell into Motorcycle
On February 28th, 2065438+08, 18, Japan's Ministry of Land, Infrastructure, Transport and Tourism announced that it would amend some notices that stipulated safety standards for road transport vehicles and introduce hydrogen fuel cell motorcycles. The new standard of hydrogen fuel cell motorcycle is that when it falls to the ground, it can prevent serious damage or even rupture to the surface of hydrogen container, and it should have certain cushioning and wear resistance.
In addition, when the collision accident accelerates, the hydrogen container should be fixed on the vehicle to prevent the hydrogen container from leaving the vehicle. In addition, the hydrogen release direction of the hydrogen fuel cell motorcycle when operating the container safety valve requires vertical downward release when the vehicle is upright, so that people around can judge the hydrogen release direction.
The ultimate solution of hydrogen-producing energy vehicles or electric vehicles is the replacement of two generations of automobiles when we look at 10, but it is only a moment in history for human exploration in the energy revolution. New energy vehicles are an expanding market, which can accommodate many products. It is better to put all your eggs in one basket than to let a hundred flowers blossom. Judging from the current technical development and practical level, although pure electric vehicles are not dominant in performance and ahead of hydrogen fuel cell vehicles in practicality and popularization, who can really lead the field of new energy vehicles in the future depends on the final competition results of technological progress and practicality.
