The Pros And Cons Of Hydrogen Fuel Vehicles

The Hydrogen Fuel Cell could revolutionize the world. This ingenious technology, which creates electricity from the chemical reactions of hydrogen and oxygen has, in its 150-year history, passed many of the critical tests along the path from invention to innovation. Recent developments in fuel cell technology and concurrent developments within the energy and automotive industries have brought the world to brink of the fuel cell age and the hydrogen economy.

The author states that fuel cell engines have several advantages over internal combustion engines and will replace them and provides three reasons. In contrast, the professor states that the reading argument is optimistic about the fuel cell engine and it won't replace the internal comustion engines and she opposes each of the author's reasons.

1. No emissions. One of the big reasons EVs are so attractive to some is that they emit absolutely no emissions. If you are worried about your direct impact on the environment, an electric vehicle will allay those concerns.

However, some pundits are concerned that adopting hydrogen energy as the sole strategy for the issues facing the automobile’s future is problematic because of the lengthy time frame in which they are projected to become ubiquitous. Furthermore, the present infrastructure for the distribution of hydrogen fuel sources or the production of hydrogen fuel cells is not only insufficient, but slow to develop. As such, fossil fuels are presently the main source for hydrogen production, which means that hydrogen vehicles do not successfully decouple the automobile from a fossil fuel economy. This is also widely inefficient because it will generate four times the carbon dioxide emissions generated by gasoline efficient automobiles. Furthermore, compressing hydrogen for the purposes of

In recent years our country has had many debates over what must be done to lessen the amount of oil that our country consumes. It is well known that we need to make some type of change to help not only the environment, but also lessen our reliance on imported oil. President Bush recently announced his new plan that could someday greatly reduce that amount of oil that Americans use by replacing oil with hydrogen fuel cells. Although this plan is a step in the right direction, it is not the answer. There are far too many downsides that could actually hurt our country in the long run. One problem is that the plan proposed by Bush will take far too long before any changes will be seen.

Hydrogen fuel cell vehicles (fcvs) have not been around for long, but over the past decade that have developed into a new potential successor of the combustion engine. Fcvs function the same as an electric cars but the difference is the hydrogen fuel cell stack. Hydrogen fuel stacks are just multiple layers of fuel cells stacked up and when hydrogen is pumped in to mix with oxygen a reaction takes place. From this reaction electricity and water vapor is created. The electricity carries on and powers the electric motor(s) in the car. The vapor is released from the exhaust and since only water vapor is released, no harm is done to the environment.

Imagine never being locked out of your disgusting gas-guzzling vehicle in sub-zero temperatures pumping your car full of toxic chemicals and then later emptying your bank account to pay for the environment killer ever again. This reality is near and approaching faster than ever before. Although, it is not completely beneficial. It is evident that at an international level, electric cars are needed. But, this is only one side of the story, despite common belief, electric vehicles are not always good for the environment. It is true that they will benefit bank accounts, however, the only way for electric cars to improve the environment is if they are powered by clean renewable energy.

Today there are several hydrogens powered cars and busses in the world. Those vehicles, thanks to their zero emission, are a step towards the environment melioration, a positive trait nullified woefully by the actuality of not being cost efficient yet.

Another area of technology that the automobile industry is working on is fuel cells. Even though it is predicted that automobiles using fuel cells will not be released until 2010, Fuel Cell Vehicles (FCV), may be the next revolutionary idea in automobiles. FCVs reflect a completely new way of thinking about automobiles. FCVs use electric

Honda has already produced a hydrogen fuel cell concept car they claim is “overall 64% energy efficient”. To put this into perspective in the average gasoline combustion engine “only about 20 percent of the thermal-energy content of the gasoline is converted into mechanical work”, making it 20% energy efficient [5]. This new line of cars could bring about jobs in the automotive industry and all industries that branch from it. As of right now the commercial market for hydrogen gas produced from the use of fossil fuels is at about $100 billion. A majority of this hydrogen goes into producing fertilizers and petrochemicals [1]. All it would take is an inexpensive source of green hydrogen, such as the one recently discovered, to completely change this industry.Overall hydrogen has the ability to bring about jobs and continued advancements in every market and industry touched by it. This could be just about every industry when considering how important transportation and shipping are to the economy; hydrogen would give them an inexpensive fuel for transport. Hydrogen fuel could do this all the while solving our most important problem of finding a renewable energy source.

Fuel availability is an everyday thing. You just go to the service station down the road and fill up for a decent price. However to produce fuels it is a bit more complicated. Fuel is made by the fossil fuels that are deep in the ground formed thousands and thousands years ago. It was made by dead organism. However, fuel is reliable but it is running out fast, so we need another energy source for our everyday needs. Hydrogen powered cars are very environmentally friendly, they do not admit any sort of harmful fumes into the air. It produces steam instead of exhaust gases. The things that makes this car able to drive is a fuel cell. It converts the hydrogen into electricity producing heat and water as by products. We collect Hydrogen from water,

Recent years have shown an increasingly large need for a practical renewable energy source for such reasons as diminishing fossil fuels and increases in greenhouse gasses. Hydrogen appears to be a way out of this gasoline-dug hole, or at least, a way out in the future. Hydrogen fuel cell cars are being engineered as we speak as the technologies to refuel them cleanly are being proposed. Unfortunately, most of the technologies associated with hydrogen are still in the prototype/pre-production stages and require better enhancements before becoming mainstream. This paper assesses the practicality of hydrogen power in cars both now and in the future while explicating the actual process of how a

 There is a serious problem facing the world right now.  It is air pollution.  The number one contributor to this epidemic is automobile emissions.  We have all heard of the issues that are involved with air pollution including the depletion of the o-zone layer, the green house effect, and acid rain.  The problem has been scoped from every imaginable angle, and now it is time to solve the problem.  I propose that each of the ‘Big Three’ (Ford, General Motors, and Chrysler) car manufacturers be required to have 10% of their product line as EV’s By the year 2010.  I propose this because it will be the start of cleaner air, EV advancement, and awareness of EV’s and how they work.

For the past three decades Oil dominates the agenda of political discussion. With scares over price volatility, sizes of reserves, international imports and least of which are the environmental impacts due to carbon dioxide and other emissions. Various speculations and educated guesses place our total depletion of crude oil within the next 50 years and there is a general consensus between environmentalists that we steer toward a hydrogen transportation system given the projected work and nonexistent carbon dioxide emissions (Environmental Technologies class lecture, Santa Clara University). However many barriers stand in the way of attaining such a goal, most of which pertaining

In order to understand the why behind the need to change from fossil fuels to hydrogen power, it is necessary to understand what that power is and how it works. Hydrogen is the most abundant and simplest element on earth. It is most commonly found as part of water. In its pure gaseous form it is extremely light, but when ignited in this state releases a large amount of energy in an explosion. In this violent reaction the hydrogen combines with free oxygen molecules in the atmosphere and creates water vapor. This is similar to the way gasoline is combined with air and ignited in an internal combustion engine in the cars used today and like with gasoline, the combustion of hydrogen has risks. In addition to the risk, some of the energy released in the reaction is lost in the form of sound and heat. As an alternative to burning, these same gases can be combined with the use of catalysts to extract the free electrons produced as liquid water is formed(Popovici and Hoble Dorel). Using cables connected to a fuel cell such as this, those electrons go through a circuit, generating electricity. This is more efficient than combustion because less energy is wasted in the form of sound and heat. Going further, greater efficiency for this reaction can be had the lower the temperature it is allowed to take place at, with 83% power at 25◦C(77◦ F)(Popovici and Hoble Dorel). As fuel cells are created with better heat management and
