What do firemen use to put out a fire? The energy that is created is then stored in fuel cells which can be used for power. Some disadvantages of fossil fuel are that -. Powering automobiles from hydrogen would be very easy, although fuel tanks would be mounted on the … top of the cars for safety reasons. Most of our technologies are designed to operate off of fossil fuels or certain renewable energy resources. We would reduce, but not eliminate, fossil fuel consumption.
The disadvantage of hydrogen as an alternative fuel is that it is difficult to produce. Storage and dispension of hydrogen to fuel cell vehicles. Hartline said she could not discuss actual production costs but cited the original Prius which was not profitable until second generation. A fossil-fueled power station can be built almost anywhere, solong as you can get large quantities of fuel to it. See the page for more.
This can be used to provide electrical energy for buildings and other structures. It's as if she was reading off a script. However, it takes a whole lot of time to separate hydrogen gas from its companion substances. Hydrogen fuel cells are completely non toxic and pose no risk to our climate. The disadvantage for ethanol, however, is that it is very expensive compared to gasoline, costing 3 times as much to produce a gallon of ethanol than it does to produce gasoline. Then there is the fact … Hydrogen is both hard to store and distribute.
Oxygen passes over one electrode and hydrogen over the other. It's a way of storing it. At the end of life the spent fuel must be maintained in a safe place for many years. In fact, hydrogen is the most abundant element on Earth. .
Also, cars need to be refitted in order to accommodate hydrogen as fuel. As a result, there is more than 50% reduction in fuel consumption. Among the many alternatives to fossil fuel that have been introduced, hydrogen fuel has proven to be one of the most promising ones owing to its many distinct advantages over carbon-based fuel sources. Hydrogen as an Alternative Future Source of Energy: Hydrogen is either produced through the steam reformation of natural gas or through electrolysis of water with renewable energies such as solar, wind or geothermal. This leads to emissions of carbon dioxide, which is responsible for the green house effect and therefore responsible for the warming of our planet. The Last Word Many economists believe that although hydrogen cars may become more popular, it may be another decade before we see these vehicles in mass quantities on the market place. Hydrogen fuel cell cars have been touted as the next step in engine and transportation technology.
It's here now until we find a real solution. Hydrogen must be extracted by way of electrolysis, which is often unpredictable and costly. List of Disadvantages of Hydrogen Fuel Cells 1. Scientists and researchers have been working at methods of direct solar conversion of water to hydrogen and oxygen that is couple with thermal cracking, biological cracking or chemical cracking of water. Stop thinking about what benefits your agenda and consider what can truly help the country, because the end of the country is the end of your free existence! Also, remember, I am just a random person on the internet stating my views, so be sure to check out all of my information, making sure that it is correct, before using it in a paper or something :-. Nitrogen dioxide is a toxic gas and can still be harmful when ingested by humans. The sp … ent fuel is highly radioactive and has to be carefully stored for many years or decades after use.
This might equate to around 75,000 miles. I think the advantage is that it's easier toconvert into energy and some of the other sources of energy likewind or hydroelectric or nuclear are harder to convert, and nuclearcan be dangerous, and wind and hydroelectric can take up a lot ofspace. The kids are taken away, the wife loses it and leaves leaving the husband that has lost everything: house, family and job is now alone. Or, despite flak being piled on them from certain quarters, will they arise from a questionable proposition today to a clear win within 10-15 years, or less? This requires enormous ammounts of energy to start. No fossil fuels are use so there is less polution ans the 100 other problems caused by using fossil fuels.
You can run a car engine off hydrogen gas fairly easily and safely in a controlled environment. Ethanol is better for the environment? Only 3 states produce hydrogen and it can only be found on earth's surface in compound form. Hydrogen fuel cells are much safer than other types of fuel. There is quite a bit to consider when looking an energy sources, below are just some of the most important. Moreover, it can also decrease lung function. Hydrogen from a pressurized tank combines with oxygen from the air, which is forced into the fuel cell.
