Oil was discovered over the fast century as the main source for fuel and in the long run for how long oil deposits stays beneath the earth? I think developing hydrogen as the future source of energy is the answer to our world oil crisis and the next alternative source of electricity to our homes and vehicles and a good protection to earth's global warming too.
Yes, hydrogen cars will become widely adopted in an effort to fight global warming (even though there is no such thing), because it is the ultimate "green machine" which emits no pollutants but only water as far as I understand. Anything that emits no pollutants at all will help reduce pollution in the air, and that is beneficial to everyone. It also reduces our dependency on foreign oil.
As the price of the hydrogen vehicles becomes lower, people will definitely buy them, thus bringing down global warming effects even though the summit at Copenhagen proved otherwise. Hydrogen cars will be especially important since no other ulterior type of car has been proposed other than electric vehicles.
Hydrogen cars won't need the costly gasoline that cars currently run on. As oil is used up over the years gas prices will go up. Also people will want to use hydrogen cars because they are green for the environment and don't want to use oil related cause because of their carbon emissions.
Transportation is one of the primary causes of the release of carbon dioxide into the air, so tackling that problem would be a good step forward in solving global warming. The technology exists for producing hydrogen cars, but one of the hold ups in wide spread use is the cost of the vehicles. If they were affordable they could be a great alternative to gas powered engines.
Hydrogen vehicles are new technological advances that will help us to combat global warming. I believe that with the right designs and marketing people will start to embrace newer vehicles. Consumers what style and innovation and with the right vehicle this can be done. All new form of Eco friendly transportation should be embraced in order for there to be progress.
Using water is not the best fuel for a car, because most of the world has cars, and drives an average of more than 1 mile a day, and it takes alot of water to fuel it, we will be killing ourselves, by supporting your family. Thats, just my opinion though, so dont take that ofensively.
I'm no scientist, but surely if we started using cars that run on hydrogen, we'll be releasing more water/H2O into the atmosphere, which (tell me if I'm wrong) is going to rise in the air, cool, form clouds and then rain... even more than it already does here in the Uk!! No thanks, we average 3 (and a half) sunny days a year so don't want to see that number get even smaller. :-)
Hydrogen vehicles show a lot of promise, especially given the power they provide and how clean they are for the environment. But I see three problems in their widespread deployment and use. First, you can't just plug them into the existing grid, so electric cars already have a convenience factor there. Two, there are not enough hydrogen stations around the country for refueling. Three, the hydrogen tanks can explode when punctured, and cars do get in wrecks. The fear factor is perhaps insurmountable.
Hydrogen vehicles sound very good on paper. They have no emissions. Their fuel source is the most common element. Their waste product is water. But, as we look deeper, they don't looks so good. The biggest issue is the availability of hydrogen fuel. It is the most common element, but that is on a stellar level. On the planetary level, hydrogen isn't extremely common. Without a large, cheap supply, adoption of hydrogen vehicles will continue to be slow going.
The widespread deployment of any technology can't happen until their is the infrastructure. Cars wouldn't be ubiquitous without gas stations, and the same goes for hydrogen vehicles. Why would anyone buy such a vehicle if they can't fill it up? Perhaps, in a few places, they'll be used, but not by the general public.
There needs to be an electric impulse to electrolyze the water to produce the energy needed to power a vehicle. Because of that, complex technology and alternate fuel sources need to be used in conjunction with hydrogen. It isn't a stop gap, because of that. Natural gas cars would be far more intelligent and, only then, as just another one of many solutions to be used concurrently.
No, I disagree that hydrogen vehicles will become widely adopted in an effort to fight global warming, because not all people can afford them. New age vehicles that are Earth-friendly may be popular among some, but the good old-fashioned gas cars will always be preferred. Also, not everyone cares about or believes in global warming. A person that either doesn't care or doesn't believe global warming is a real threat will not change cars to combat global warming. Some people, usually the Earth-friendly "green" types, will probably choose Hydrogen vehicles, but not the average Joe.
Hydrogen can be used to store energy, but there are no readily accessible hydrogen resources on Earth, like there are oil resources. Hydrogen must be manufactured, which requires energy. This energy can come in various forms, but they do not make hydrogen effective in fighting global warming. Using fossil fuels to produce hydrogen releases carbon dioxide, and so it does nothing to solve the problem. It is possible to use electricity to produce hydrogen, and the electricity can be generated in a carbon-free manner. But, in this case, it is more efficient to simply distribute the electricity over the power grid to charge electric cars. For these reasons, I believe it is unlikely that hydrogen vehicles will become widespread.
America is incredibly dependent on oil. It has proven very difficult to wean the average consumer off oil, considering that they love huge cars and oil-based products, such as plastics. Americans will be using oil until every single drop of it has been used. While a lot of people are turning to hybrid cars, they are regarded by most people as "tree huggers" and hippies. Most Americans are not bothered by environmental issues, and many think that global warming is a hoax.
The disadvantages of hydrogen as a vehicle fuel greatly outweigh the potential advantages. Proponents of hydrogen vehicles note that hydrogen can easily be produced from renewable resources and does not produce carbon dioxide when combusted. Unfortunately, there are some major disadvantages to using hydrogen as a vehicle fuel. The primary disadvantage is that hydrogen has very low energy density and must be compressed to extremely high pressures in order to store enough fuel for a decent range between refueling. The high pressures require bulky, expensive storage tanks and can only be refueled at special stations. Another disadvantage to the use of hydrogen as fuel is that the conversion processes to produce hydrogen from primary energy sources like natural gas or sunlight are relatively inefficient.
