Concentration & Location

Hydrogen is the most abundant gas in

the universe

Exists in every living organism or

biomass

Hydrogen is concentrated in the

oceans in the form of H2O

Hydrogen does not naturally exist in its

pure gas form.

Success

Alternate forms of hydrogen allows

industrial companies to benefit by

processing metals

Hydrogen is utilized as fuel by

NASA to propel their shuttles in

space.

Hydrogen has been fairly

successful in acting as fuel cells to

function as batteries.

Obtainment of Hydrogen

Methods of obtaining hydrogen by

extracting hydrogen molecules

from compounds

Electrolysis- splitting the molecules of a

compound into its basic elements

Biomass gratification- heating

agricultural wastes and wood chips to

the point where they transform into

hydrogen and various gases.

Stream reforming- steam heating

systems used to separate the hydrogen

molecules from the compoundmethane

Usually used for industrial proposes

Advantages

Advantages of using hydrogen

energy:

Has a minimal environmental impact

as a fuel

Can be produced domestically and

reduces dependence on foreign oils More fuel efficient than gasoline-

powered cars

Hydrogen has 3 times the energy of

natural gas

Energy to produce hydrogen could

come from nuclear, solar, wind or lesspolluting sources of energy

Comparison of Net Energy

Hydrogen has a negative energy

compared to the other resources

This is due to the fact it takes a large

amount of energy and fossil fuels to

manufacture hydrogen molecules

Dependency on Hydrogen

Increase dependence on hydrogen

because:

It is renewable in contrast to fossil fuels

Emissions from hydrogen combustion

are water and heat which dont impact

the environment negatively. Technologies are being developed to

further the use of hydrogen so that it

can be produced, stored, and used

efficiently

It will decrease our dependence on

foreign oils and help provide a clean,efficient renewable resource for the

future.
