With lower emissions than fossil fuels and a lower burning temperature than petrol, Hydrogen Energy is the energy of the future. It is one of the cleanest form of propulsion emitting only water and heat when combusted, fast tracking goals to make the world zero-emission. Further, since it burns at such a low temperature, less money is spent on replacing equipment due to it deteriorating from wear and tear. Green Hydrogen energy is made through a process called electrolysis. This is when an electrical current is passed through water which splits the molecule up into its two formative elements, hydrogen and oxygen. As a result of this the hydrogen atom bonds with other hydrogen atoms whereas the oxygen produced becomes a useful byproduct. This results in little to no carbon footprint, hence why this will be the energy of the future.
