Objectives Describe how hydrogen may help
improve public health Describe the benefits to the environment Explain how hydrogen may help
stimulate the economy Describe what energy security is and how
using hydrogen can help attain it Explain the future of hydrogen-powered
vehicles Explain the suggested actions to support
hydrogen
3
Used in multiple ways Produced from multiple sources Energy security and
independence Air quality Renewable possibilities
Why Consider Hydrogen?
4
Advantages of Hydrogen Created from water, can be recycled
to produce more hydrogen Cleanest fuel available when
combusted Leaks/spills will quickly evaporate
and do not pose any threats to the environment
Domestic production will allow for energy independence
Special Note:Producing hydrogen with renewable energy and using it in fuel
cell vehicles holds the promise of virtually pollution-free transportation and independence from imported petroleum.

6
Provides more energy than any conventional fuel
Can be refined from any substance that contains hydrogen
Betterment of health, environment, economy, energy security
Hydrogen Benefits
7
Harmful emissions from combustion of fuels cause high pollution levels, smog
Combustion of hydrogen produces far fewer emissions than conventional fuels
Aftertreatment systems can help reduce some of the NOx emissions
Fuel cells
Health Benefits
8
Did You Know?
About half of the U.S. population lives in areas where air pollution levels are high enough to negatively impact public health.

9
Cleanest burning fuel available Combustion does not release carbon
dioxide Carbon dioxide fuel is a GHG
Environmental Benefits

10
Domestic natural gas deposits can be used to create hydrogen
Domestic production, job creation, tax revenue
Fuel cell industry = $2.5 trillion by 2021
Economic Benefits
11
Did You Know?
Hydrogen-powered fuel cells promise reliability of the U.S. electric power transmission grid by reducing system loads and bottlenecks.

13
Creation of 680,000 jobs by 2035 Offset demand for foreign oil Research will create “Global
Connectivity” Domestic construction of plants,
parts, equipment
14
About half of the oil consumed in the U.S. is imported
Hydrogen can be produced domestically
When used in efficient vehicles, hydrogen can help alleviate the need for foreign oil
Energy Security Benefits

16
Development in U.S., Canada, Japan, England, Germany
First FCEVs became available in 2002 but only prototypes/leases available
Research to make hydrogen production economically viable
Supply infrastructure still needed
Hydrogen – Today and Tomorrow

18
The Future of Hydrogen Global interest continues to grow Prototypes from automotive
manufacturers Infrastructure and vehicle
developments still required
The Future of Fuel Cells Fuel cell development = next step
toward hydrogen economy Extremely efficient, reduce
emissions, replace fossil fuels

Suggested Actions Limited immediate actions Restricted consumer lease options in
Southern California Heavy-duty applications available
through government partnerships Small-scale model applications for at-
home use

Upon completing this material, can you: Describe how hydrogen may help improve
public health? Describe the benefits to the environment? Explain how hydrogen may help stimulate
the economy? Describe what energy security is and how
using hydrogen can help attain it? Explain the future of hydrogen-powered
vehicles? Explain the suggested actions to support
hydrogen?

1. List two advantages of hydrogen.2. True or False: Most current
hydrogen fueled vehicles are prototypes, not available to the public.
3. True or False: Hydrogen may alleviate U.S. dependence on foreign oil.
4. True or False: The use of hydrogen in ICEs produces no emissions.
