Hydrogen is burned or used in fuel cells enable an attractive option for future cars. This nontoxic gas could serve as a pollution-free energy machine of many species. If it burns, it releases no carbon. Carbon dioxide, a potent greenhouse gas.
And if fed hydrogen in a fuel cell stack a battery like device, which produces electricity from hydrogen and oxygen it capable of driving an electric car or truck with only warmth and water as of products.Ease environmental problems, including air pollution could fuel cell vehicles more than twice the efficiency of today's cars could anbieten.Wasserstoff, therefore, help, and its dangers.
Weight for weight, hydrogen contains three times the energy of petrol (gasoline), but it is impossible to store hydrogen gas as compact as the conventional liquid fuel. One of the most difficult technical issues is store efficiently and securely enough hydrogen on board driver demand provide the driving range and performance. Feasible storage devices keep sufficient hydrogen today's minimum acceptable travel (driving range-almost 500 km)-a tank to support not compromised on luggage. These tanks must be filled or recharged within a few minutes.Many researchers in the U8 spends internal organisation, lot are considerable efforts to these limitations überwinden.Infact, 17 Governments are obliged hydrogen and fuel cell technologies ahead. In 2005 the US Department of energy provide4 $ 30 million to 80 research projects to fund.
A 500 km. minimum driving range is one of the main operational objectives of the automotive industry. Engineers believe that a ~ Allon gasoline is, on an energy basis one kilogram of hydrogen.(A US gallon is almost 3. 8 L) While today's automobiles about 20 litres of petrol, 500 km travel needs, the typical fuel cell vehicle hydrogen should only 8 kg. Several automakers have tested about 60 hydrogen-powered prototypes and demonstrated ranges from 200 to 300 km drive.
In 2010, some car manufacturers expect the first production of fuelcell cars hit the road. A hydrogen storage system to carry enough fuel for at least a 500 km trip and also light enough to haul around a car.For a system with a weight of 600 kg (a reasonable ~ size of a vehicle), hydrogen would be six kg.gespeicherte. Deep cold stored hydrogen it can improve the stored energy density and could be used in cars, it disadvantages regardless.Neverthe less, drives one world-famous automobile manufacturer BMW of this technology to the Straße.Das will integrate vehicle called hydrogen 7, able to run on either gasoline for 500 km. or liquid hydrogen for 250 km internal combustion engine.
Dry compression: scientists increase energy density, to the chemistry of hydrogen gewesen.In use ~ liquid phase, hydrogen molecules two bound atoms contain each. But though hydrogen molecules are chemically bound to certain other elements can be packed still closer together than in liquid hydrogen.
Some researchers focus on a class of substances called reversible metal hydrides 1969 discovered by chance at the Philips laboratories in the Netherlands. Investigators found that a samarium-cobalt alloy would absorb when exposed to hydrogen, something like a sponge water sucks pressurized hydrogen gas.If the pressure is then removed, the hydrogen within the alloy again other words out come the process was reversible.
In the United States, scientists such as James Reilly and Gary Sandrock, has pioneered the development of hydride alloys.This work formed the basis for the today's widely used nickel metal hydride batteries.The density of hydrogen in these alloys is 150% more than liquid hydrogen!Such properties of metal hydrides well suited to Autos.Obwohl that current metal hydrides have restrictions, many automakers as it approaches most profitable low pressure to see in the near future.Toyota and Honda car engineers plan-a so-called hybrid approach in a system, the a solid metal hydride with medium-pressure (less than 10, 000 psi), predictions connects you could reach a driving range of more than 500 km.
Designer materials: recent developments in the nanoscale engineering have resulted in a variety of new high-surface-area materials, with some ~ more than 5, 000 m Mt.der per gram of Materials.Carbon-based materials are mostly light weight and low Kosten.Im over the centuries, the basic promise - and challenge-the use of hydrogen for transportatiQ1has unverändert.Dennoch search for a suitable container is basically hydrogen cars soon approval Totravel people around the world save over the next decade without pollution or polluting of Heaven about us.
