Hydrogen Cars

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

As you go throughout your day, you use energy many times. Turning on the lights, using the toaster, taking the bus to school, all examples of using energy. Slowly, the fossil fuels that we are burning to get this energy are harming the environment. Hydrogen energy and biofuels would bring many benefits to Long Beach,

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 can easily combine with other elements making numbers of compounds. Such as ones as water, ammonia, methane, and table sugar. Hydrogen is produced by heating natural gas with steam to form a mixture of hydrogen and carbon monoxide. There are multiple uses for Hydrogen. Hydrogen is used to convert oil into margarine.

The automotive industry is one of the largest industries in the entire world. As the world’s population grows and economic development occurs, the auto industry also expands. Unfortunately the growth in car numbers has had a negative environmenta, impact due to carbon dioxide and particulate emissions generated and released from the combustion process. Technology has developed a solution by utilizing the concept of hydrogen fuel cells. As the years have passed, there has been continuous development on automotive fuel cells and now it has come close to mass production of these vehicles. The main problem is the continued development of hydrogen fuel cells and their infrastructure may not be worth the cost.

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.

In early 1870’s many researcher’s tried to use some of the alternative fuel to have a better efficiency and to reduce the emission rate, hydrogen was one of the element which they have found out to be

It derives energy from spinning water turbines. Hydroelectric power is a low-cost, renewable, air pollution-free energy source. Unfortunately there is not much room for this source left in the US and building large dams, flooding valuable river valleys, and eliminating free-flowing rivers are the negative externalities of this alternative. Electrolysis of water could be used to convert biomass (plants or plant-based materials) into methane or electricity to generate hydrogen gas. Current technology with little improvement could lead to these fuels being used more abundantly. Moreover, the storage, use, and transportation of these fuels would be

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.

However, there are some cons to hydrogen fueling which is why scientists are still in conflict about this topic. Firstly, in order to extract the hydrogen necessary to power cars and other vehicles it would have to come from methane. By doing this it would lead to a cleaner fueling source however the methane would release large amounts of carbon dioxide in the process. To add, once the hydrogen is harvested in order to split it into individual molecules it would take lots of electrical power which would again have huge impacts on the environment and we still haven't converted hydrogen into a usable fuel source yet. Als this hydrogen reaction is very explosive, which raises the question would it be safe to use in vehicles when all it takes is a single spark for it to explode. Finally in order to fuel the cars, gas stations would have to be remodeled as well as the cars we currently use today. This would cost billions and billions of dollars just to allow for the new system of hydrogen fuel to be

Cars are an integral part of life today in the modern world. In America, as an example, society has become very reliant on automobiles. In the past, towns and cities where small microcosms, overall. Today, however, towns and cities have grown larger, and farther apart. Roads flow across what used to be countryside, through mountains, and over rivers. This links the people together and allows for the transaction of goods like food, materials, and even ideas. However, cars today, as a marvelous technological advancement as they are, run off of fuels that produce a foul gaseous byproduct that continues to erode our environment day by day. Any glance onto a city street or arching highway will show the massive amount of these cars that are on the road today, all of these are releasing their carbon by-product into the atmosphere. There is also a rife search for alternative energies today; cars powered by hydrogen gas may be an answer. While hydrogen powered cars have their shortcomings, hydrogen powered cars are a more effective, efficient, and environmentally friendly option compared to internal-combustion automobiles.

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

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
