There are certain algae that produce hydrogen as a waste byproduct, and the cultivation of such algae and collection of their hydrogen emissions has so far proven somewhat successful (AE 2009). Continued refinement of this process and a bolstering of its efficiency could lead to commercially and industrially viable production levels. There are also methods for extracting hydrogen from waste materials that makes use at least partially of the natural breakdown of these materials; though energy is used in this decomposition, it is not energy transformed and applied at human expense, eliminating its strain on the system (AE 2009). Complex new storage mechanisms are also making the concept of hydrogen fuel cells in cars more viable (U.S. Dept. Of Energy 2009). There have been several major test projects involving hydrogen-powered vehicles in land, air, and sea, including the use of drone spy planes by the U.S. military, municipality waste removal trucks, and a UPS delivery truck (AE 2009; EPA...
All of these show the great promise that hydrogen fuel cells carry for the future.
Fuel Cells in Green Engineering The energy tomorrow is beginning to be available today. Fuel cells, which just a very few years ago were a pipe dream, are becoming g a reality, and they are used in areas ranging from space exploration to toy motivation (Joy). The promise of the fuel cell can be seen in the fact that they use the most abundant source of energy on the planet, Hydrogen
People seeking to make a fundamental change in the way they transport themselves will likely need a great deal of information, some of which may provide greater clarity while others may provide confusion and resort in them seeking out another alternative product. The consumer may then look for information that will support their inquiry into a commitment to a Hydrogen Fuel Cell Vehicle as opposed to one of many
According to Dr. David Thompson, assistant professor in the Department of Chemistry at Memorial, long-term goal is to make fuel from sunlight, a field known artificial photosynthesis. The larger question revolves around whether a system can be designed to take captured solar energy and create molecules that can be utilized as fuels (Hester, 2007). The general idea, of course, is that the Petroleum Era will be replaced by the Hydrogen
Fossil Fuels & Their Impact on the Environment Impact of Fossil Fuels on Environment Fossil fuels are formed by anaerobic decomposition of organisms over a period of millions of years. When burnt, they produce significant amounts of energy per unit weight and cannot be reused to supply energy. They are thus nonrenewable resources. The applications of fossil fuels range from use in motor vehicles, trains and industries to household consumption in stoves
A similar method, called gas-to-liquids (GTL), which also uses the FT process, is receiving a lot of attention these days. In this method, natural gas is used as the feedstock. Waste or natural gas that cannot be marketed is partially oxidized into CO and H2 gases. This synthesis gas is then supplied to a synthesis unit to similarly produce a liquid fuel. The development of synthetic jet fuels to augment
Conclusions Whether it is solar power, used vegetable oil, turds, wood, or hydrogen research and experimentation is the way forward. These cheap resources have already been proven effective in various ways and manners. The need of the day is to develop new energy technologies and apply them in the most useful and practical way possible. If we want global economic stability then eco energy sector requires due attention. We have witnessed
