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.
Solar energy can be turned into electricity through solar cells 15%=cheap, 40% efficiency=expensive. Caloric theory of heat=caloric fluid flows from hot object to cold. Heat engine=
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
A second major problem with the plan is not easy to see at first. You must look much closer at what types of research is being done. There are two ways that hydrogen fuel cells can be made. One is by a reaction with oxygen. These cells are about 70% efficient and the only emissions are water vapor. The second way it by using oil or coal to make the cells. These cells are about 33% efficient and release harmful emissions into the atmosphere (Abelson 1469). I feel that we should fund research into using oxygen as opposed to fossil fuels when making hydrogen
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
Currently, hydrogen is generated from fossil fuels by the steam reforming of methane or natural gas. At extremely high temperatures from between 700-1100℃, steam water reacts with methane in an endothermic reaction to yield syngas (synthesis gas), which is a fuel gas mixture consisting primarily of hydrogen and carbon monoxide.
One of the leading causes of lung cancer is believed to be air pollution. With nearly all automobiles running on gasoline, there is a much higher chance of obtaining a life threatening disease. There are many different solutions that attempted to fix the problem of automobile pollution but only one has come close. The hydrogen fuel cell consists of two electrodes, a positively charged cathode, and a negatively charged anode. The fuel cell has an electrolyte that sends electrically charged particles from one electrode to the other. The hydrogen fuel cell is able to produce energy as long as oxygen and hydrogen are available. Hydrogen fuel cells don’t produce emissions and are also able to power all motor vehicles. These special fuel cells do not cause pollution or create dangerous byproducts, their only byproducts are water and heat. In addition, a hydrogen fuel cell is way more efficient than gasoline powered engines. Most forms of transportation emit harmful emissions and cause pollution. The hydrogen fuel cell is an environmentally friendly alternative to
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.
Even Stanley Meyer, the most renowned innovator of hydrogen technology, failed to penetrate the market with his revolutionary work. Perhaps Joseph Romm’s prediction that hydrogen energy will still have little place in the market by the year 2030 is accurate. Perhaps, in spite of its potential benefits to society, this technology simply faces too much opposition to be made publicly known and utilized. Perhaps my grandfather was a wiser man to keep his findings to himself. Perhaps, however, hydrogen still has a chance. In spite of Stanley Meyer’s tragic death, and the discontinuation of his plans, his work and findings were most definitely not in vain. Roughly ten years after Meyer’s death, all of the patents and property rights to his work had
Hydrogen has already been under the micro scope for many years as an alternative fuel source to us because of its abundance and power. We have simply been lacking the
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
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
Nowadays the most common energy resources come from Fossil Fuel, which according to research it shows that more of 85% of all energy that is consumed in the United States. It takes millions of years for the Fossil Fuel to actually develop and ready to be used, and the main concern of Fossil Fuel is that it cannot be consumed over and over again or reused. Through this analysis it can be assumed that because it takes millions of years for the fossil fuel to develop, and we came up with two assumptions that would lead the innovation of producing energy using different resources. The first assumption is that there is more fossil fuel that is used rather than what is provided or reserved by the nature. This act
