Hydrogen is the most abundant element in the
universe.
5
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.

• 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.

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.

Hydrogen can be produced at small stationsor at
large plants and delivered to users.
14
Hydrogen Storage
Hydrogen can be stored as a gas, liquid, and
even in a chemical compound.
15
The Hydrogen Storage Challenge

• To store enough hydrogen on-board a vehicle to
  enable drivers to travel 300-350 miles before
  refueling

Hydrogen storage tanks

Hydrogen Delivery
Hydrogen pipelines exist only in certain regions
of the country.
18
Once hydrogen has been easily produced and
safely stored, it can generate electricity
using a fuel cell.

Hydrogen-powered fuel cells can supply energy to
power anything from automobiles to homes to
computers.

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.
