Only hydrogen is used as fuel and emissions are only water – General Motors has achieved zero pollution and zero emissions of hydrogen-powered future cars Hy-wire and Hydro Dynamics 3 took a test drive in Beijing last week. Although the parties kept silent, there was news that the GM hydrogen car and the Audi A8 from the general public, Brilliance China, and the BMW 5 Series, which was about to go offline, had entered Zhongnanhai together. If the hydrogen-powered fuel cell vehicle is a new energy vehicle developed and competed by major international companies, General Motors' Hy-wire has changed the past practice of replacing the hydrogen engine with a gasoline engine in a car. The "line pass" manipulation technique. Hy-wire has no engine, no conventional form of steering, throttle and brake pedals and other mechanical transmission systems, and rely on electrical signals to control. It can be asserted that the "hydrogen economy" will be a fulcrum that will revive the glory of the global automotive industry in the 21st century. Hydrogen is the most abundant and renewable energy source on the planet. Hydrogen-powered fuel cell vehicles are also the commanding point for major auto companies to seize the core technologies of the new century automotive industry. The hydrogen economy not only brings about revolutionary changes in energy and the environment, but also opens up new ideas for traditional automotive basic structures and technologies. Hy-wire undoubtedly made the latest interpretation of the hydrogen economy in its efforts to "redefine the car." Although automakers in the United States, Japan, and Europe have introduced hydrogen-powered prototypes, individual models have even received commercial sales. However, huge development costs and technical improvements are waiting for hydrogen power to replace petroleum energy. The director of the Honda Institute, Ito Takashi, predicted to the author that it will take 30 years for hydrogen power to gradually replace oil as the mainstream of automobile energy. GM's director of fuel cell division Bimo said in Beijing that GM is committed to producing affordable fuel cell vehicles after 2010. GM’s goal is to be the first car company to sell 1 million fuel cell vehicles. In addition, the construction of supporting facilities for the hydrogen economy is also difficult to accomplish overnight. However, the shortage of global energy resources and the severe pressure on environmental protection have promoted the active attention of governments of various countries to the progress of the hydrogen economy. Schwarzenegger, the new governor of California, announced that he will build a "hydrogen highway" in California. That is, a hydrogen fueling network is established along the expressway. As a rising automotive giant, China's auto energy policy is closely linked with global energy supply and environmental protection. The country has arranged a 863 plan for electric vehicles. Although the plan also regards hydrogen fuel cells as a development perspective, it has recently put the main direction of attack on the global automotive industry for almost 100 years and has been able to surrender for a long time. It has announced the abandonment of traditional electric vehicles. For a specific vehicle such as a large city bus, it is better to solve problems such as short cruising range of electric vehicles and scrapped battery pollution. Therefore, the financial resources and technology of China's scientific and technological community can be competent in the research and development of specific vehicle electric vehicles. It is said that by 2008 Beijing will build 1,000 electric buses for the Olympic Games.
