In today's fast paced world we always try to better the current traditional things, whether it be a test score, A lap time or in this case the source of our electricity. With the dawn of the green movement, the focus is to find cleaner, more efficient and cost effective methods to keep our society running as expected. There are many potential methods, and with billions being spent on them each year in the hope of finding the perfect energy source. In the following case study, I discuss if Hydrogen could be this perfect source of clean, efficient and cost effective energy. What is hydrogen?

Scientific theory - Can hydrogen actually produce energy? Since the beginning of signs of negative effects from current energy sources, mankind looks for an energy source that is clean and renewable; solution of this problem may be the most common item on our planet, something that makes up 70% of our planet - Water.[1] Water as you may know is made of two chemicals elements, Hydrogen and oxygen. Each molecule of water is made of two hydrogen (H2) and one oxygen (O) atom resulting in the commonly recognised H20 (water). Due to the fact that the chemical bindings between the 3 atoms that make water are very stable and very strong any reaction that occurs is very intense and generates a lot of energy. From what is said above, Hydrogen looks to be the perfect energy source, lots of energy output with no negative output, (only output is water). The only problem is that the power was known about for more than 200 years, and in these 200+ years, scientists are yet to unlock a method to extract energy this energy, rather then an already developing method of splitting water in hydrogen and oxygen (also known as nuclear power). ...read more.

Conclusion

The second major problem is that hydrogen in it's pure form is rare and although the most abundant thing in our universe it is nearly always bonded with something else, such as water, and of course energy is needed to break the bonds in a process called electrolysis. The third and possibly the killing blow for hydrogen fuel cells is the fact that more attainable and efficient technologies are already here, such as the electric car which are simply charged via a plug-in technology. Conclusion After re-reading the points I have made, The advantages and the disadvantages about Hydrogen, I believe Hydrogen is not going to be mankind's perfect fuel source due to a variety of factors. Their may be many positives such as the fact that the only by-products are water and heat but the negatives are also many. But the main problem is the cost. With each fuel cell running into the millions due to the fact that the catalyst is platinum unless mankind finds another cheap alternative catalyst, Fuel cells aren't going anywhere soon. ?? ?? ?? ??

  1. In this coursework, I aim to find out the different properties of gold and ...

    Pure gold also occurs naturally with a very high density; alloying enables it to lower its density, making it much lighter. Alloying gold also means that it can adjust its colour, giving it a range of colours to choose from; for example, alloying gold with silver will make the gold

  2. Should the UK build more Nuclear Power Stations?

    more people have died in a single coal mining accident than nuclear accidents in history put together (Although the life span of nuclear power has been nowhere as near that of coal mining) and nothing can be made failsafe so there is no point in criticising a particular system for not being what is impossible.

  1. Electrolysis with water

    The scientific knowledge for this is that when the solution is a stronger solution, it has less water molecules in them. When the water molecules split this slows down the movement of the ions because the water molecules block them up therefore when there are less of them this makes the current flow faster.

  2. Plastics- A Benefit or a Disaster? (Science research coursework)

    has many polymer branches; this will result in HDPE being much stronger than LDPE. Therefore HDPE would be used for such a job because it is much less stretchy than other plastics and much stronger. In addition HDPE can also be used in temperatures up to 120(r)C which means that it is very durable.

  1. Alternative Energy Sources

    The world uses 15 terawatts of power each year. With the rates of energy consumptions on a global scale, it is vital that we find other sources of energy that produce the same energy efficiency as non-renewable sources like coal, oil and natural gas produced.

  2. Nuclear Power of the future

    These neutrons may split other nuclei, releasing more heat and more neutrons. This chain reaction is called nuclear fission. It is what makes nuclear power possible. The heat therefore is released b y nuclear fission is what we use to produce electricity.

  1. Are Electric Cars better for the Environment?

    Electric cars are only ?zero emission? if they get their electrical power from a renewable source. The real potential will only be realised when electric cars are coupled with renewable power generation. Disadvantages for electric cars The bad news is the battery [4] The batteries used to power electric cars are very heavy.

  2. Alternative Energy Research Essay

    If the number of vehicles continues to increase, then the predicted 55 years will definitely decrease. With such a limited source of fossil fuels, there is an immediate need to seek alternative fuels to keep the world energy economy healthy.
