To answer the question of weather or not hydrogen can be the fuel of the future, we first must understand what hydrogen is and to find out how it can be used to create energy.

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.


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. ?? ?? ?? ??
