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...
The target refers to Scope 1 and 2 emissions (GHGs from assets owned and operated by GTAA), but there are additional plans to help tackle Scope 3 emissions (GHGs from airport business partners that aren't directly under GTAA's control).TODD ERNST...
A hydrogen fuel cell is comparable to a battery in that it can produce electricity without relying on combustion or emissions. But unlike batteries, fuel cells don’t need to be recharged, as long as they have access to a source of hydrogen and oxygen. Because proper battery disposal can ...
recharge the electric battery, FCEVs use a built-in fuel cell to generate power. This takes place when hydrogen stored in the onboard fuel tank reacts with oxygen. The reaction generates electricity which powers the motor, turns the wheels and gets motorists from A to B with zero car...
Now, chemical reactions are complicated, to say the least, but the basic facts in the case of fuel cells are relatively intuitive. Firstly, 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 ...
Scientists have created a catalyst they believe can radically reduce the price needed to create hydrogen.
How does hydrogen work in a car then? From its tank, the hydrogen is passed through an anode in a fuel-cell. The anode has a catalyst – usually platinum – which forces the hydrogen to split into protons and electrons. The protons get sucked across a ‘proton exchange membrane’ (PEM...
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 ...
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.)...
