Diego Hydrogen I.T.I.S. Pinifarina IV C mecc Hydrogen engines Slide 2: What is hydrogen?
Hydrogen is the chemical element with the
atomic number 1 and it is the first element on
the periodic table. It is represented by the
symbol H. Hydrogen is the lightest and most
abundant chemical element, constituting
roughly 75 % of the Universe elemental mass Hydrogen Slide 3: From water: Hydrogen is produced on an industrial scale by the electrolysis of water
The Sulfur-Iodine Cycle: it is much more efficient than water splitting.
From urine: Hydrogen can also be made from urine. Using urine, hydrogen production is 32% more energy efficient than using water.
Fermentative hydrogen production
-The fermentative hydrogen production and
biocatalysed electrolysis use biological materials Electrolysis of water HOW CAN WE PRODUCE HYDROGEN? Slide 4: Vehicles
Buses, trains, canal boats, golf
cars, motorcycles, ships, airplanes
and submarines can already run
on hydrogen in various forms.
NASA uses hydrogen to launch
Space Shuttles into space. There is even a working toy model car that runs on solar power, using a regenerative fuel cell to store energy in the form of hydrogen and oxygen gas. It can then convert the fuel back into water to release the solar energy. Hydrogen in vehicles Slide 5: A hydrogen vehicle is an alternative fuel vehicle
that uses hydrogen as its onboard fuel for motive
power. The power plants of such vehicles convert
the chemical energy of hydrogen into mechanical
energy either by burning hydrogen in an internal
combustion engine or by reacting on hydrogen
with oxygen in a fuel cell to run electric motors. Many companies are working to develop
technologies that might efficiently exploit
the potential of hydrogen energy for mobile uses. The advantages of using hydrogen as an energy are the following:
hydrogen is prepared without using fossil fuel inputs
the vehicle propulsion would not contribute to carbon dioxide emissions Slide 6: It is ecological: hydrogen is a clean fuel and if its production happens through renewable energy sources it doesn’t create any type of polluting emissions. Furthermore the result of its combustion is simple water!
It is inexhaustible because we obtain hydrogen from water and it is the most abundant element on the Earth . Hydrogen is an economical material
Hydrogen is versatile, for example we can use it to produce electric power or as a fuel for vehicles
If we develop the technology necessary for a massive use of hydrogen, we will be able to stop burning fossil fuels Hydrogen advantages
