Hydrogen Fuel Cell Energy Hydrogen fuel cell energy is a form of energy that has great potential, but is more or less of a running joke to the science community. Practical applications like a hydrogen fuel cell car will always be the marvel of the next decade, or maybe the decade after that... Hydrogen fuel cell cars are no emissions vehicles. But it is tricky to harvest the energy of hydrogen fuel cell vehicles. Hydrogen is an energy carrier, not a source. The energy has to harvested by adding electrical energy to water, thusly splitting the H20 into one oxygen and two hydrogen atoms. Inside the fuel cell, the two recombine and make electrical energy, which powers the vehicle, and the exhaust is pure water. Current prototypes of these vehicles run about $1,000,000; certainly not pocket change. Hydrogen, also, has a low energy density, so the hydrogen must be compressed, which uses energy, (Introduction to Renewable Energy. 2012). Another application to hydrogen fuel cells is at home. According to Fuel Cell & Hydrogen Energy Association, “Fuel cells are ideal for residential zones. They are virtually silent with no moving parts and provide reliable power 24/7. In addition, a fuel cell big enough to power an entire home is about the size of a traditional AC Unit. Fuel cells already power thousands of homes in Japan and are beginning to do so in the United States.” Obviously, this type of application could also be amplified to a larger scale, for business and work

Hydrogen Fuel Cell Essay

fossil fuels such as coal, oil and natural gas. Normally electricity is converted through a two step process. Fuels are burnt converting chemical energy to heat. The heat is then transformed into electricity by generating steam to turn turbines. This is a highly inefficient method which requires a development of another more efficient method of producing electricity. In addition, fossil fuels are non – renewable energy resources. They are limited and will eventually run out. Fossil fuel cells produce…

Essay about Disruptive Innovation

portable power. 2.4 Challenges Following are the challenges that a fuel cell faces today: Cost: Cost of a fuel cell is a major concern right now. Due to expensive materials like platinum is used as a catalyst, the cost of fuel cell shoots up. but the research is on and it is most likely that the cost of a fuel cell will come down to $30 - $50/KW for transportation and $1500/KW for stationery power. Storage: Storage of hydrogen is again another concern especially for the transportation system…

Hydrogen Disadvantages

Even though hydrogen is awesome i almost every way, there is a downside to it. one of the very few disadvantages of hydrogen is that it is very hard to move around. Where as oil can be sent through pipelines. Another disadvantage in hydrogen is that its highly flamable. Hydrogen itself is a very powerful source of fuel. we all jnow the effects of hydrogen bomb that was dropped on hiroshima and nagasaki in japan. its highly flamable and always in news for the risks associated with it. Finally, there…

Fuel Cells Essay

simple device is referring to a fuel cell. The book definition of a fuel cell is a “device that generates electricity by a chemical reaction”(#1). The purpose of using a fuel cell is to create an electrical current that can be directed outside the cell to do various types of work. Some examples of work that a fuel cell may be used for may include; powering an electric motor or lighting up a light bulb. In order for a fuel cell to complete these tasks, each fuel cell needs two electrodes known as an…

Hydrogen Power Essay

FACT SHEET Hydrogen power can mostly be used for automobile applications, but can also be used as a source of heat and electricity for buildings, fertilizer, and refining petroleum. Hydrogen fuel cells were used to fill space shuttles Although hydrogen is the *most abundant element on earth*, it is hard to obtain to use for energy. 95% of the hydrogen extracted comes from natural gas. Water is the remaining. There are different processes that separate the element: Electrolysis : splits oxygen…
