Hydrogen Powered Cars

There are many current technologies focusing on saving the fossil fuels used on cars. One is the commonly known “Hybrid Cars”. Hybrid cars are the current “star” for cars that save fossil fuels. They have an electric battery as well as a combustion engine. That way, you can use electricity from an outlet to charge your car, and while you are on the road, you can rely on electricity to power you until you run out, then you switch to gasoline. This way, you can completely not use fossil fuels such as gasoline for

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.

First, the article claims that the fuel cell engines utilize easily available , renewable resources. However, the professor refutes that by saying that the resources are not easily available. Although, hydrogen is available in water, but it's not usable. She said it must be in apurified liquid state and it's highly artificial, so the process of produce and stor the liquid hydrogen is not easy because

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

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.

Have you ever wondered how we get gas for a cars ,lawnmowers, and other petroleum powered devices ? in order to know we have to go back to the beginning or where it all started. America paved the way for petroleum products , we practically created the industry . It all started with a man named Andrew Carnegie, Carnegie created an oil empire he controlled the drilling , transportation and refining of oil. But soon the industry was crowded with new competitors , one of these competitors was John Rockefeller ,John rockefeller would soon put Carnegie out of business. The Petroleum industry lead america into some of the world's greatest inventions, america had used the discovery of petroleum as a way to make life easier. We created cars, motorcycles

Every single day society uses different technology to get through the day but we never know where our help was made or how, even how it was made. One key factor in any type of tech that we use is what keeps it running and how efficient that power source is like gasoline. A lot of tech and automotive are built to run on fossil fuels and also gasoline is the biggest source of natural raw material to be used as a energy. Gasoline is the life source to most American transportation systems and vehicles. Petroleum products and internal combustion engines have helped the United States into a world power over the past century and continues to power the overall majority of motor vehicles like land, sea, or air transportation. Even though people

Some of the concerns regarding hydrogen that are currently limiting its widespread throughout the world is hydrogen gas is very time consumer which requires a lot of time to free up from its elements even though it is less expensive than regular gas. Hydrogen gas cannot be moved through pipelines like oil due to it is a very light gas. Hydrogen gas require energy such as oil, coal, and natural gas to separate it from oxygen which will not just have logistical issues but also environmental issues.

Federal Government and oil companies put forward hydrogen fuel cells as a better alternative to gas and battery electric cars. In contrast, interviews with two hydrogen experts gave details why fuel cell vehicles are not likely to be available for another 15-20 years if ever, whereas battery electric technology is available now, has been rapidly improving since the mid 1990s and is cost effective.

Gasoline is widely used through out the world to power things, but unfortunately its soon becoming something of the pass since petroleum is a nonrenewable source. Through out the years this type of energy provider has given us the power to power our cars to drive us to our work, school, and home; to powering our lawnmowers to helps us maintain our front and backyard. It’s a one of a kind, and what lays in the future well just take it one step at a time.

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.

There is Ethanol (which is produced domestically from corn and other crops), biodiesel (vegetables and animal fat), natural gas (fossil fuel), propane (liquified petroleum gas), and hydrogen. These alternative fuels can help out by replacing the oil in cars. The the big issue at stake is that cars produce a lot of pollution and put the Earth in danger because of climate change. For example, another fuel that can help the environment is compressed natural gas, which costs less than gasoline, burns cleaner, and provides comparable power. Ethanol, on the other hand, can reduce the demand for foreign oil, low emissions, high octane, and can potentially be produced from waste material. Diesel is 30% better fuel economy than an equivalent gasoline car, and any diesel car can run on a blend of renewable biodiesel. Perhaps by changing from fossil fuels to alternative fuels or electric cars. The possibility of helping the environment from pollution exists, and it can better the automotive industries by making them substitute a different substance to replace the oil. As much as oil is relied on a lot, the change to alternative fuel will benefit a lot of people in the future because they will not have to go mining for different types of fossil fuels just like coal or

small, positively-charged proton with a negatively-charged electron orbiting very fast, a model analogous to the earth orbiting the sun, or the moon orbiting the earth. Fuel cells take advantage of this structure. Using a membrane and a catalyst, hydrogen is broken up into a proton and an electron. While there are many different membrane models for fuel cells, the most appropriate one for car travel is the Polymer Electrolyte Membrane (PEM, also called the Proton Exchange Membrane). It is called this because protons are able to easily pass through the membrane. However, because the membrane does not allow electrons to pass through it, the electrons take a detour through an electrical circuit to the other side of the cell. If hydrogen is supplied into the cell at a steady rate, the stream of electrons in the electrical circuit creates electric power. However, like all batteries, you need a positive end (cathode) and a negative end (anode); in other words, the hydrogen atoms must have a “reason” to make this electrical circuit. And what is this reason? Oxygen. With oxygen at the other end, hydrogen is more than willing to create this current so that it can bind and form H2O, or water on the other end.

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
