With gas prices escalating and fossil fuels becoming limited, scientists have been researching an alternative fuel source that will be more abundant and cost efficient. Issues with our current fuel source include the pollution that is emitted in our air and water sources and the fact that fossil fuels are becoming scarce. One alternative to gasoline is the use of hydrogen as a fuel source. With hydrogen as a fuel source pollution will be in decline, it has become increasingly more abundant than fossil fuels through extracting hydrogen from various sources, and is domestically produced. There are many pros to using hydrogen as an alternative fuel source; namely, its abundance, its low pollution, and the fact that it is being researched and extracted domestically. Hydrogen is one of the most abundant elements on earth and can be found in water, hydrocarbons and other organic matter. Because of hydrogen being so abundant scientists are able to extract it from a variety of sources, therefore, the problem with hydrogen as a fuel source is how to exactly make hydrogen an efficient fuel source. Currently hydrogen is extracted from natural gas, but this releases the greenhouse gas CO2 and uses up a limited resource. This does not relieve our current issues with using up fossil fuels, just displaces them. Recent research has suggested a means of how to resolve both of these problems. Zhang, a research scientist from Virginia Tech, and his team have altered an enzyme that can

This source mainly concentrates on the use of hydrogen fuel cells as an alternative to the United States dependency on foreign oil. It elaborates on the negatives of our countries reliance upon external sources for the vast majority of our power production needs, and suggests that hydrogen fuel cells are the answer to a sustainable energy future. The author is a writer for CQ Researcher who concentrates on energy, environmental, and defense issues. While the article is mainly geared toward individuals interested in the automotive industry and the applications of hydrogen fuel cells in vehicles, it does an excellent job of contrasting oil based
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
Another use for Hydrogen was
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
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,
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.
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.
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

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
Hydrogen as an Alternative Fuel What is Hydrogen? The simplest and lightest fuel is hydrogen gas (H2). Hydrogen is in a gaseous state at atmospheric pressure and ambient temperatures. Hydrogen is being explored for use in combustion engines and fuel cell electric vehicles.
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
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
