Benefits Benefits
Environmentally friendly Potentially less expensive
and more efficient Alternate source of energy Completely replaces
gasoline in transportation Stabilize the economy
NegativesNegatives
Expensive in the beginningNeeds more advances in storage of
hydrogenNeeds advances in producing hydrogenNeeds advances in the membraneThere is not a nationwide refueling
infrastructure
Environmentally FriendlyEnvironmentally Friendly
Does not create any greenhouse gases
Does not cause global warming
Only byproduct is water vapor
Needs Advances in producing Needs Advances in producing HydrogenHydrogen
Currently the production from natural gas and petroleum creates greenhouse gases
Two other ways to make hydrogen are through electrolysis by splitting water into hydrogen and oxygen, or through a thermochemical reaction in nuclear power plants
ContinuedContinued
Electrolysis involves adding electricity to water, which separates the hydrogen and oxygen
hydrogen created without greenhouse gases as byproduct.
However no industry of large scale exist
ContinuedContinued
Heat from nuclear reaction creates a thermochemical reaction that split water molecules into base elements.
In addition the electricity created by the power plant can be used to create more hydrogen through electrolysis.
However, dangers of a nuclear power plants have stifled this idea.
Cost and efficiencyCost and efficiency
1 gallon of gas = 1kg of hydrogen 1kg of hydrogen = 75 miles, 1 gallon of gas costs $4, 1 kg hydrogen costs $6-$10. However hydrogen
could potentially cost only $2-$4 per kg. Current gasoline engines work at 30% efficiency Hydrogen fuel-cells work upwards of 50%
efficiency.
ContinuedContinued
Hydrogen stored in tanks that will hold 2.5 to 3.5 kg. and go about 200 miles
Desired distance is about 400 miles.Scientist have 3 theories as to how they can
double the amount of storage of hydrogen.

Liquid statePressurized stateCompressed gas stateHowever, they have not made much
progress in perfecting any of these states.

Another problem is the membrane.1) The membrane is currently very
expensive to produce 2) The membranes are not as efficient as
they could be3) The membrane only lasts 2,000 hours, it
needs to be around 4,000 hours.
Alternate source of energyAlternate source of energy
Hydrogen will completely replace gasoline in the transportation industry
Can be used as a generator for nearby households or business
A hydrogen car stores enough energy to power a nearby home, which results in a more energy efficient environment
Stabilizes Economy Stabilizes Economy
With the transition over to hydrogen for all of our transportation needs around 66 percent of our annual oil consumption will be cut.
This will relieve our needs for foreign oil and therefore lower the price of oil, which could help stabilize the economy.
No Hydrogen Fuel No Hydrogen Fuel InfrastructureInfrastructure
Only 100 hydrogen refueling station in the U.S., most are in New York and California.
There needs to be around 12000 stations costing $1 million each.
“Chicken or the egg” problem, people won’t buy cars without fueling stations and fueling station won’t build without people buying hydrogen fuel-cell cars.
Implementing Hydrogen Fuel-Implementing Hydrogen Fuel-cells cars into the economycells cars into the economy
Government should increase grants for the advancement of hydrogen fuel-cell cars.
Once prototype is ready government should provide incentives in order to have consumers buy this new technology and the creation of a new hydrogen fuel infrastructure
FinancesFinances In the next 30 years it will cost about 1.3 trillion for
the expansion of the North American gasoline economy.
About 300 billion for oil refineries,that will most likely be replaced by hydrogen facilities.
It will cost several hundred billion to produce these hydrogen infrastructures as well, so by cutting down on the amount spent on building oil refineries and pipelines we would be able to use it towards building hydrogen facilities and save hundreds of billions of dollars.
Globe ProgressionGlobe Progression
Many industrialized countries have given grants and encouraged the advancements of hydrogen fuel-cell cars.
However the amount of money given doesn’t meet the amount of money needed to make hydrogen fuel-cell cars a near future reality.
