Would hydrogen vehicles be practical for owners? Hydrogen cars require less maintenance than gasoline cars. Dennis Weaver said in an interview with Motor Trends, "Running on hydrogen extends engine life and reduces maintenance, as no carbon builds up in the combustion chamber or on the spark plugs and the blow-by gases are so clean that the oil rarely needs to be changed”. Dennis Weaver argument is true as hydrogen doesn’t build up on surfaces however using hydrogen makes it very venerable to catch aflame and must be insulated very cautiously. Conversely hydrogen cars cannot be charged at home like electric cars. Electric cars can be charged essentially anywhere the electric grid extends, including, most importantly, a car-owner's home. This contrasts very sharply with hydrogen cars that will only be chargeable where special hydrogen fuelling stations are built, and none are yet constructed. It is reasonable that hydrogen fuelling stations aren’t built yet as there is only a limited amount hydrogen cards and most of them are experimental. However in the future and like I said before, if hydrogen cars were made in a world-wide scale I would expect hydrogen cars to be very much similar like electric cars but faster with a fuelling station at home or on the towns. The other social problem is: Are hydrogen fuel cell vehicles safe? . Fuel cell critics point out that hydrogen is flammable, but so is gasoline. Unlike gasoline, which can pool up and burn for a long time, hydrogen dissipates rapidly. Gas tanks tend to be easily punctured, thin-walled containers, while the latest hydrogen tanks are made from Kevlar. Also, gaseous hydrogen isn't the only method of storage under consideration--BMW is looking at liquid storage while other researchers are looking at chemical compound storage, such as boron pellets. It is true that hydrogen is safer than gasoline in a way as dissipates very quickly. It is also a relief that the latest hydrogen tanks are made of Kevlar even though it is an expensive material and car companies are researching for better ways to store hydrogen. But other people point out also that hydrogen fuel cell containers are weak/dangerous at present. The storage issue is a potential show-stopper – it's clear that you can't build a hydrogen economy around high-pressure on-board storage. It would be fatal to H2 cars if they were prematurely introduced into the marketplace with this inadequate storage technology. I don't think your average soccer mom or dad wants to be a foot away from 5000- or 10,000-psi hydrogen canisters--which in industry are treated with great respect, put in separate facilities with blow-out walls, and so forth. We need – according to the American Physical Society – a whole new material for storage, and if you were to ask how long it might take, the answer is it could take a very long time. This opposite argument does have a point as hydrogen is very explosive but they are missing the fact, that many car companies are doing their best to come up with a better storage for hydrogen. And the statement that to make a whole new material for hydrogen storage is going to take a long time, is not exactly true because in the 1900s people thought space travel was impossible however the first rocket to go out into space was in 1930 and then accelerated to make giant rockets to take humans into space. So my message is humans can invent things very quickly.
. The most common way to produce hydrogen is electrolysis, running a current through water and causing the hydrogen molecules to separate from the oxygen molecules. Critics point out that it takes more electricity to create the hydrogen then it will generate in a fuel cell. While that is true, it also takes energy to create a gallon of gasoline. Oil has to be pumped, transported, and refined. However I would say it takes more energy to make and transport hydrogen than gasoline so there is not any point on comparing hydrogen by gasoline. Also because there would not be any profit of energy, wasting the earth’s resources. Looking at the other side of the argument too much energy is required in compressing/liquefying hydrogen. Compressing or liquefying hydrogen requires a further input of energy equal to 10 or 30 percent of the hydrogen's energy content, all of which ranks it among the least convenient and practical of all transportation fuels. This is a good point as it is a further waste of energy which righteously classifies hydrogen among the least convenient and practical of all transportation fuels. However since hydrogen fuel had been introduced it makes it mostly experimental. But in the short coming future, . Processes show some long-term promise for producing low-cost, clean hydrogen, including reforming biomass feedstocks like corn-based ethanol (which can be carbon-dioxide neutral--releasing only as much CO2 as the plants consumed in the first place), and experimental methods like converting sugar water to hydrogen at around 400 degrees F using a nickel-zinc catalyst or starving green algae cells of sulfur to cause them to generate hydrogen. This is a promising statement that cleaner methods of transporting and creating hydrogen are being research proving my statement in the future hydrogen vehicles would be greater improved. But from the opposite perceptive, one could say that the cleaner methods to transport and create hydrogen being currently research, would take so long to create and so it would be a waste of time researching them. However when looking at rockets many people the same which is why the invention of rockets lagged but in the end they became in use world-wide. In the other hand leaked hydrogen damages the environment like chlorofluorocarbons. A study from the California Institute of Technology says it is likely that mass-produced hydrogen will leak, which would be very damaging to the environment, because hydrogen destroys ozone in the same way that chlorofluorocarbons (CFCs) do. That is true because if hydrogen cars were made world-wide there would be a large amount of leaks and the ozone layer is already very fragile. Conversely hydrogen leaks would be rare because of the high security around hydrogen and later future improvements on hydrogen storage. Also if there were a large leak, most of the hydrogen will react with the normal oxygen to create water (H20).
So my final message is many people know hydrogen is clean but hydrogen vehicles might sound dangerous at first because of its damaging properties, however since it is just newly come out and is experimental we must have faith that further in the future it would be greatly improved.
