Many Lives, Many Masters of the Hydrogen Economy


In terrorist attacks and global demand stimulated by the strong international market oil prices have been high, while the demand for energy is growing. In this case, the search for alternative energy sources is increasing, “hydrogen economy - PA2487UR, PA2487UR-G, Satellite 510 Series, Hp laptop battery,Satellite 4300 Series, Satellite Pro 2100 Series and 182281-001, EVO N100, Evo N1000V, Business Notebook nc8000, Presario 2800T” concept, therefore the surface.


With the world economy has sustained rapid development of the huge demand for energy led to the emerging energy crisis, 337607-001, 337607-003, dg103a , 336962-001
398876-001, PB992A, PB994A, PB991A the scientific community is exploring a wide range of future energy technologies.


Hydrogen as a clean, efficient and secure new energy sources, be regarded as the most development potential of the 21st century energy. Over the years, developed countries in the world of scientific research and production practice has proved to hydrogen is dependent on oil from the most economical source of energy. Experts even believe that hydrogen will be the key to the future of the world’s main source of energy.


Hydrogen’s advantages of birth and the day after tomorrow,337607-003,


In terrorist attacks and global demand stimulated by the strong international market has been high oil prices. Especially in the next 20 years, countries are expected to increase in demand for energy will reach more than 50%. As the earth’s oil resources are limited and uneven distribution, in the long run, there is no reason for oil prices to be optimistic.


In this case, the development of alternative energy sources is increasing(pa3356u-1brs, pa3356u-2brs, pa3356u-3brs, toshiba satellite a50 battery, toshiba tecra a3x battery, toshiba tecra a9 battery, toshiba tecra m3 battery, toshiba tecra a2 battery, toshiba tecra m5 battery, toshiba tecra m2 battery, toshiba tecra m6 battery, toshiba tecra m9 battery, toshiba tecra s3 battery, toshiba satellite a55 battery). Among them, hydrogen energy to replace oil, build a “hydrogen economy” of the future, it is quite highly regarded by many experts. It is reported that the benefits of the use of hydrogen energy is the obvious: the universe, hydrogen is the most abundant element, its everywhere on Earth. In addition, after the hydrogen is burned water and heat,398876-001, not like oil or coal, 337607-001, 337607-003, dg103a , 336962-001
398876-001, PB992A, PB994A, PB991A the combustion produces carbon dioxide and other harmful substances. In addition, the fuel cell can also be hydrogen into electricity to provide drive power to all means of transport.


Multi-use form of hydrogen, either through the combustion heat generated in the heat engine mechanical work, but also can be used as materials for fuel cell energy, or converted to structural material used for solid-state hydrogen. Using hydrogen instead of coal and oil, not of existing technology and equipment to do a major transformation, the internal combustion engine modified to use a little.


Hydrogen has been the application of “pioneer”


In recent years, automobile hydrogen fuel cells in the small and the advancement of power has made great progress. Canadian-made hydrogen fuel cell buses have been put into practical use; the United States General Motors Corporation has launched the fuel cell prototype vehicle, Ford Motor Company also plans to manufacture the end of the year about 30 fuel trucks; other car manufacturers such as Toyota, Honda ready in the next 5 years to allow hydrogen vehicle road tests.


U.S. President George W. Bush State of the Union speech in 2003,PB992A, proposed 1.2 billion U.S. dollars into research and development use hydrogen fuel cell vehicles. U.S. Department of Energy announced that it would invest 350 million U.S. dollars the first funds to subsidize automobile factory(8n544, dell latitude d800 battery, dell inspiron 8500 battery, dell inspiron 8600 battery and f4809a, f4812a, 319411-001, dell presario 2100 battery, dell presario 2500 battery and pcga-bp2nx, pcga-bp2ny and a1012, m8244), private companies and research institutions to conduct research and development of hydrogen vehicles, including the scope of the study of hydrogen storage, fuel cells, infrastructure development and hydrogen education and so on.


Now, scientists are studying a “solid hydrogen,” the spacecraft. 337607-001, 337607-003, dg103a , 336962-001
398876-001, PB992A, PB994A, PB991A Solid-state hydrogen can be used as a spacecraft structural materials, but also as fuel spacecraft. During the flight, the spacecraft all the non-critical parts and components can be converted to energy “consumed.” In this way, the spacecraft in the universe can be a longer flight time.


In supersonic aircraft and long-range intercontinental aircraft powered by hydrogen fuel research has been conducted for many years, PB994A,now in prototype and test phase. In the area of transport, the United States, Germany, France, Japan and other major powers have long been the introduction of motor vehicles to hydrogen-fueled model cars, and hundreds of thousands of kilometers of roads to run the experiment. Among them, the United States, Germany, France and other countries is the use of metal hydrogen storage, liquid hydrogen is used in Japan.


Hydrogen is not only a high-quality fuel, or petroleum, chemical, fertilizer and metallurgical industry of the important raw materials and materials. Oil and other fossil fuels hydrogen refining needs, such as hydrocarbons by hydrogen, coal gasification, heavy oil refining, etc.; chemical system ammonia, methanol also need hydrogen; hydrogen can also be used to restore the iron ore; use hydrogen fuel made from battery can directly power generation; the use of fuel cells and hydrogen - steam combined cycle power generation, the energy conversion efficiency will be much higher than the existing thermal power plants. With the advances in hydrogen production technology and means of improving the hydrogen storage(dell latitude d820 battery, dell latitude d830 battery and pa3191u-1brs, pa3191u-2brs, pa3191u-3brs, pa3191u-4brs, pa3128u-1brs, toshiba portege m200 battery, toshiba portege m400 battery, toshiba tecra m4 battery), hydrogen energy to the energy in the 21st century style stage show.


“Hydrogen Economy” bottleneck to be broken,PB991A


At present, the separation of the high cost of hydrogen is to develop hydrogen energy economy, one of the biggest problems. Hydrogen does not simply exist in nature, but must take it from other substances separated. It is best to use wind, solar or geothermal electricity, it separated from the water. Preparation of hydrogen technology has a long-term application in industry, 337607-001, 337607-003, dg103a , 336962-001
398876-001, PB992A, PB994A, PB991A but production costs are too high. Only the cost of hydrogen production is currently reduced to 1 / 10 of the following in order to really start the Hydrogen Economy. Scientists are studying the use of biochemical or biological methods to produce hydrogen, in order to reduce production costs.
