Today, there are vehicles running on hydrogen fuel cells while this abundant element, hydrogen is also used to produce electricity. First invented in and then later used by NASA to power space shuttles and rockets, a fuel cell uses fuel source and either air or water to produce electricity.

This can be used to provide electrical energy for buildings and other structures. Since it has many uses, it is being considered as a power source for the future. Despite its benefits, there are also negative effects that are apparent with the use of hydrogen fuel cells.

Let us discuss about the two sides of this energy source.

List of Advantages of Hydrogen Fuel Cells 1. Carbon-emission Free Advocates for the use of hydrogen fuel cells posit that unlike other sources of power, these fuel cells do not emit harmful carbon emissions in the air that cause pollution and affect global warming.

Although Advantages and disadvantages of gmos chemical process involves burning hydrogen, it emits water, heat and other emissions but not carbon. The chemical reaction between hydrogen and water does not produce pollution but instead, releases electricity to be used in various applications.

Accessible and Clean One of the advantages of using hydrogen as an energy source is its being readily available. Since it is considered the simplest elements, its supply in the atmosphere is abundant.

And although it might take time to break down the compounds and separate them, its being plentiful and easily accessible make up for the time it takes to complete the process.

Moreover, the end-result is a clean and powerful source of energy. Importance in Science and Technology Hydrogen fuel cells have many applications and are being used by industries, machinery, motorcycles, automobiles and NASA.

Hydrogen fuel is used to launch space shuttles, making it a significant factor in science and technology. In fact, NASA has been using hydrogen gas for decades and had used fuel cells as an alternative energy source along other fuel cell types such as methane and hydrogen peroxide.

Being a non-toxic substance and environment friendly, it has many uses as opposed to other fuel types. Renewable Energy Source Hydrogen is the most abundant element in the universe. Consequently, it becomes one of the renewable sources of energy like solar energy coming from the sun.

Unlike limited energy sources like fossil fuels and nuclear energy reserves, energy coming from hydrogen becomes a very practical and significant alternative energy. Fuel Efficiency Due to the fact that hydrogen is capable of producing more energy per pound of fuel as compared to gas and diesel, it becomes more fuel efficient.

Cars powered by hydrogen fuel cells can run more miles than automobiles that run using gas and solar-powered vehicles. When it comes to combustion technologies, plants that are powered by conventional combustion methods only produce about 33 to 35 percent of energy.

Conversely, when hydrogen fuel cells are used in manufacturing plants, electricity produced can reach up to 65 percent. List of Disadvantages of Hydrogen Fuel Cells 1. Nitrogen Dioxide Emission Critics of hydrogen fuel cells argue that although these cells do not emit carbon after burning, they give out nitrogen dioxide and other emissions.

Nitrogen dioxide is a toxic gas and can still be harmful when ingested by humans. Experts say talk about the risks of respiratory problems such as lung edema from exposure with lethal dose even for a short period of time.

Moreover, it can also decrease lung function. Storage Issues Apart from taking much time to separate the compounds of hydrogen, this element is also a challenge to move and transport. Compared to oil which can be channeled through pipelines and coal which can be moved to one location to another using trucks, transporting hydrogen can be expensive.

This is one obvious setback of this element since storage and transport can be considered impractical. High Cost Aside from having to spend a lot of money to transport hydrogen, the time it takes to break down its elements makes the process expensive as well.

This is also one of the reasons why hybrid cars are also costly. As long as no other options are applied to make the process faster and easier, hydrogen as fuel cells will remain to be pricey. Additionally, most cars being manufactured are still powered with conventional energy source like gas and diesel.

Converting these already manufactured cars into hydrogen-powered vehicles will require a lot of work and money.The Greenpeace Mission - Humans and nature live together on the planet earth. Unfortunately, humans have destroyed much of our own environment. You most likely eat at least some GMOs.

Crops that are genetically modified to resist herbicides or produce insecticides came on the market in Asexual reproduction in the plants. The asexual reproduction is the production of new plants without using of seeds, it can incorporate new characteristics into the plants, it is easier and cheaper, it can produce uniform plants, and some plants do not produce the seeds.

The advantages and disadvantages of GMOs is a necessary conversation we must have. At some point, we must figure out how to feed our growing population levels.

New farming methods can only produce a limited amount of change. Disadvantages of GMOs. 1. GMOs could be dangerous to some insects. This is because the new genes of the crops can be deadly to certain insects like butterflies that are not actually dangerous to crops.

2. The people who oppose GMOs aren’t taste good as compared to naturally produced crops. 3. List of Disadvantages of Animal Testing on Cosmetics.

1. It is still possible that animals receive inhumane treatment. During the tests, it is highly possible that animals would experience inhumane treatment, where they are being restrained.
