Hydrogen ENERGY!
Hydrogen does not exist in nature by itself, but it is found as part of a compound in abundant and diverse resources such as the fossil fuels natural gas and coal. • What is the most abundant compound on earth?
Water = H2O Two Hydrogen Atoms One Oxygen Atom
Chemistry review… • Hydrogen has 1 proton and 1 electron • Oxygen has 8 protons and 8 electrons • Both are non-metal gases • Both are naturally diatomic (H2 and O2) when by themselves • When they react with each other they form water
Electrolysis: The process of using an electrical current to split water into hydrogen and oxygen.
When the electricity needed for electrolysis is generated using wind or solar power, for example, electrolysis can be a clean and renewable way to produce hydrogen. solar panels wind farm
Scientists worldwide are researching ways to produce hydrogen safely, cleanly, efficiently, and cost-effectively. Steam Methane Reforming – • This method involves using high temperature steam to extract hydrogen from natural gas. • Both hydrogen and carbon monoxide are produced. • Today, 95% of the hydrogen produced in the United States is made through steam methane reforming.
Fuel cell animation • How a fuel cell works • At the anode, Hydrogen gas gives up its electrons to produce hydrogen ions and allows for the flow of electrons (electricity) • At the cathode, the oxygen and hydrogen recombine to form water • The membrane (PEM) can also SPLIT the water, so the whole process can begin again
Other hydrogen production technologies use various resources… biological material nuclear energy algae
Hydrogen-powered fuel cells can supply energy to power anything from automobiles to homes to computers. Picture it…
Hydrogen is a clean form of energy. It can be used in fuel cells to create electricity with the only byproducts being water and heat.
