Renewable Hydrogen

what hydrogen is

What this energy type is

• Pure hydrogen gas
• Not an energy source
• Energy carrier like electricity
• Requires utilizing a primary energy source

How it is captured and distributed

• Many objects already have hydrogen attached to them
• If taken, it can be burned...
• ... or make electrical power
• It is a primary energy source

Forms of energy

Electricity is formed by electrons flowing in a path. Stripping electrons from hydrogen would allow the electrons to flow freely.

Hydrogen Cell

• Anode is the first layer
• Anode strips the atom of its electron 2H2 → 4H+ + 4e−
• Proton exchange membrane is the second layer
• Cathode is the third layer
• Hydrogen bonds with oxygen and makes water
• O2 + 4H+ + 4e− → 2H2O

History of hydrogen

It was Henry Cavendish (1731-1810), a British physicist, who was credited with the discovery of hydrogen in 1766.

History of Hydrogen Cells

• The first fuel cell invented: 1801
• First proton-exchange membrane invented:1950s
• First hydrogen cell used for space travel: 1960

Usage Percentage and Cost

Hydrogen energy is about 1% of all energy used

The cost is very cheap. About $0.0015 per gallon.
