Hydrogen: The Best Alternative Energy Source Essay

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

` The continuous use of fossil fuels is leading the Earth on a path to destruction. Generations of advancement and technological innovation being brought down to rubble. Natural disasters wreaking havoc on innocent people across the world. Temperatures soaring above 125℉ globally. These are the results of the excessive use of fossil fuels. A chief concern in the 21st century is global warming and climate change, and the continued use of fossil fuels for the technology and daily lives of humans is key to blame. Decades ago, these problems were much more daunting and seemingly unsolvable than they are today, with the use of alternative energy sources and new

The United States relies heavily on fossil fuels as its main source of energy and with the limited supply, we 'll have to develop and utilize alternative sources for clean, renewable, cheap and effective energy to power this country and the world into the future. It will be important for the health of our planet to utilize renewable resources that have no greenhouse gas emission. Out of necessity the world will eventually need to stop using fossil fuels for energy.

Throughout the entire modern age, mankind has used fossil fuels to meet its energy requirements. Coal, oil and natural gas have lit homes and powered machinery for centuries, driving civilization forward. But as human

In order to comprehend why we need to shift to alternative energy sources, we must first review the history of fossil fuels and how it transitioned the world during an important era of history. Fossil fuels played an extremely significant role in the era of the Industrial Revolution. The Industrial Revolution began in the eighteenth century. Fossil fuels were the ultimate ideal source of energy during the Industrial Revolution. Coal was especially used the most during the revolution. It burned “cleaner” and hotter than what wood did. The Industrial Revolution without a doubt expanded the use of coal. During the revolution, coal was used for steamships and with the escalating business of transporting goods across the country, it played a major

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

There are many elements that occur naturally on earth that can be put to good use to help with everyday life. Some of these elements, however, can cause harm if proper control is not taken when working with the element. Hydrogen is one such element that can be beneficial if used correctly and catastrophic if not.

The formation of the other two fossil fuels (crude oil and natural gas) took millions of years just like coal. Oil and gas come from the remains of small animals and plants. Long ago, when the animals and plants died, they sank to the bottom of the sea. The dead matter formed a large mass, which over time was covered by layers of sand, silt, and mud. As the weight of the sediment increased, the mass became more and more compressed. Then, the heat and pressure of the Earth eventually turned the mass into oil and gas. If the heat applied during the formation was low, then more oil was produced than gas. If the temperature was

The most of global energy production produces from fossil fuel such as coal, oil and natural gas. The vast fossil fuels generate energy which use for many purposes for instant residential, transportation and industrial sectors. While the rate consumption of fossil fuel higher than their formation leads to oil price crisis. Another concern of fossil fuel combustion is the impact on the environment. Global warming is a significant problem which results in increasing concentrations of greenhouse gas in the atmosphere. These problems drive researchers and societies to search alternative energy such as switching to renewable energy or carbon-free energy to replace fossil fuels. For example Nakata et al., (2011:465) show ‘low-carbon society’

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

Besides, methanol and methane, renewable resources, such as bio(ethanol) and glycerol, are considered as promising source of hydrogen. Nevertheless, their use remains limited as the applied reforming processes run at high temperature. On the other hand, hydrogen can be produced from metal and metal compound such as NaBH4. Nonetheless, these processes have obvious disadvantage such as toxicity, price, and safety. Although, decomposition of formic acid and amine adduct produces hydrogen under mild conditions, but need a catalyst to complete the process. It is noteworthy to mention that these resources are limited and we have to find a substrate which is ample on earth. So, H2 in future must be obtained from slitting of water, whether, electrolytically, photolytically, thermolytically or biolytically; however, the catalyst is a prime consideration.

For years man has relied on energy in order to be successful in life. The industrial revolution relied on coal for the new inventions brought into the world. Life as has never been the same since then. However since that time, there has been little done to improve on energy efficiency and humans still primarily rely on fossil fuels for energy. For over a hundred years the Earth has become more polluted and dirtier than ever before. Now, with new, innovative technology there is an opportunity to change that and to rely on renewable, cleaner sources of energy. The main source of energy for the world should be alternative energy instead of energy from fossil fuels.

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

The energy resource that we mainly use today are fossil fuels. Fossil fuels are one of the most popular energy resource that can be found on earth. There are three types of fossil fuel, oil, coal, and
