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

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.

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

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.
