Essay On Pros And Cons Of Hydrogen Fuel

1502 Words7 Pages

What Are the Pros and Cons of Hydrogen Fuel Cells? Hydrogen fuel cells are among the cleanest energy sources today, and they are increasingly used by many people to power up their vehicles. Actually, they now serve as an alternative fuel to automobile technology, converting hydrogen into electricity to charge the batteries. Other than those using hydrogen, there are even other categories, including phosphoric acid (PACF), molten carbonate (MCFC), proton exchange membrane (PEM), alkaline fuel cells (AFC) and solid oxide cells (SOFC). With a focus on just hydrogen fuel cells, the technology certainly comes with many benefits. However, it also comes with certain disadvantages. The pros and cons of hydrogen fuel cells are very interesting information, especially for people who are always using them and even for those who are planning to do the same. Here are some, if not …show more content…

They have an abundant source of energy. Hydrogen is a resource that is more plentiful compared to gasoline that is derived from oil, which in turn is a limited resource. On the other hand, hydrogen can be found in many natural resources, like water, that are infinite. This means the use of the fuel cells can be forever. List of Cons of Hydrogen Fuel Cells 1. They are extremely expensive. Initially, hydrogen fuel cells are extremely expensive to manufacture. However, just like other new technologies, their costs would come down to price levels that are affordable by normal consumers with mass production. Now, we are in a transition period, where many fuel cell manufacturers are investing literally hundreds of millions of dollars in gearing up for mass manufacturing and, at the same time, trying to develop a variety of markets for such products. Though these cells’ price is seen as a great disadvantage, things are changing now. 2. They can just be used in short-distance travels. As these power sources do not contain a high level of fuel, you can just use them for a while to nearby

In this chapter, the gloom is relieved by the hopeful planning of the three men — George, Lennie, and Candy — toward their dream. For the first time in his life, George believes the dream can come true with Candy's down payment. He knows of a farm they can buy, and the readers' hopes are lifted as well, as the men plan, in detail, how they will buy the ranch and what they will do once it is theirs. But while Steinbeck includes this story of hope, the preponderance of the chapter is dark. Both the shooting of Candy's dog and the smashing of Curley's hand foreshadow that the men will not be able to realize their

The pros for the methane hydrate divide into 3 part. First,Methane hydrates have great amount in seabed. “Estimates suggest that there is about the same amount of carbon in methane hydrates as there is in every other organic carbon store on the planet,” Methane Hydrates have a huge reserve on the edge of continental shelves where the seabed drops sharply away into the deep ocean floor. It can be the alternative energy to lower the consumer of the coal and oil.

If we switch over to all electric engines, the gas industry will have a drastic decline in business and could possibly go out of business. Gas stations make it easy to just fill up and go more miles, while electric needs time to fill up, and also needs special electric service requirements of 220 volt plugs sometimes and higher amperages to charge the vehicle. Gas stations also provide a place to buy food for the road. I believe that gasoline engines overpower electric for many reasons, mostly because electric is les reliable than

Even though they may not seem like it, Solar Roadways do have some disadvantages. 1. Initial expenses a. Gaining enough money to get this project up and running would take a miracle considering each individual panel costs about 7,000 dollars. b. Preparing the ground for the roads would also require more money than it takes to just lay down some asphalt.

The main way that oil and natural gas reserves are acquired are through the means of Fracking. Also known as hydrofracking, this method utilizes a drill that drills down thousands of feet underground, which is then flushed with millions of gallons of water along with additive chemicals at high pressures to break the rocks sheltering the reserves. This method of attainment is quite risky as it comes with many unfavorable consequences that are quite unbeneficial. Like fossil fuel plants, fracking also releases greenhouse gasses like methane(Potential Health and Environmental Effects of Hydrofracking in the Williston Basin, Montana), which is worse than carbon dioxide and causes air pollution. Alongside that, pollutants like Benzene and Xylene also leak out during the fracking process, which is known to cause serious health conditions and even death in some cases due to the long exposure to the pollutants(Potential Health and

While it is proven that solar panels are tremendously helpful in terms of reducing the use of fossil fuels, it comes with a price. Solar panels are expensive; solar panels are expensive to make, install, and maintain. While solar panels do eventually break even in terms of cost, this takes years of operation to bring a profit. Studies have also shown that solar arrays have the potential to cause changes in temperature and precipitation by altering the amount of solar radiation absorbed by the earth (Harvey, 2015). The biggest problem with solar panels is the cost.

Gasoline and diesel are fossil fuels and aren 't infinite. Battery electricity are better, they don’t pollute and don 't burn fossil fuels. Instead of having a gas tank and having to fill it up at a gas station, these cars have batteries in their place and can be recharged with a larger charging station and needs 220 volts. The recharged batteries stay charged until the car is driven. Some people say that battery powered cars are slower, but it isn’t by much and battery powered cars think is worth slowing down a little if it means saving the planet.

A lot of people love to hear about energy efficient and environmentally friendly options out there. The electric vehicles today serve great benefits in keeping emissions down and using a more friendly alternative energy source. In my opinion they have made an impact on the environment, but a major benefit in using this alternative resource is less cost to fuel the vehicle. Gasoline is very expensive today, and using the energy that is used to power our home, is much less expensive and more available than gas. The environment, as claimed by environmentalists, suffers due to the emissions of automobiles today.
