H2, that is, hydrogen fuel, is a molecule consisting of two hydrogen atoms. It is very flammable and can be used as a fuel that doesn’t produce any greenhouse gas emissions such as carbon. This makes it highly appealing as a renewable energy source in the global effort to mitigate clima...
Hydrogen fuel cells work by separating hydrogen into protons and electrons. The protons pass through a membrane, while the electrons create a separate current that can be utilized before they rejoin with the protons and oxygen to produce water. What are the main components of a hydrogen fuel cel...
One long-distance flight consumes fuel which a car uses in several years' time, but they cause the same amount of pollution. So, some people think that we should discourage non-essential flights, such as tourist travel, rather than limit the use of cars. To what extent do you agree or ...
you have your fuel, the reactants whose electrons will produce a current in the circuit – in the case of a hydrogen fuel cell, these are hydrogen (H2) and oxygen (O2). Then, you’ve got your electrodes – two per cell, to be...
These gases are then recombined in the fuel cell to produce electricity. (The advantage of doing things that way, rather than using the Sun's energy directly, is that you can store up hydrogen in the daytime when the Sun's shining and then use it to drive the fuel cell at night.)...
Energy giant AGL this weekunveiled plansto produce hydrogen power at its Loy Yang A coal station. But how do we transform coal, which is often thought of as simply made of carbon, into hydrogen – a completely different element? In fact,coalis not just made of carbon. It also contains ...
The method of producing the fuel additive is a step of passing a supply stream containing C4 hydrocarbon through a methyl tertiary butyl ether unit to generate a first process stream, passing the first process stream through a selective hydrogenation unit. The step of generating a second process ...
The Invention of the Fuel Cell In 1839, Sir William Grove invented the first fuel cell. He knew that by sending an electric current through water, it could be split into hydrogen and oxygen (a process called electrolysis). He hypothesized that by reversing the procedure, you could produce el...
that’s how carbon dioxide is produced inside the body. Since glucose, fats and proteins are all used as fuel sources for this reaction, the rate of carbon dioxide production is less than the rate of oxygen consumption. In simple words, we produce less carbon dioxide than the amount of oxy...
