Title: By team domination
1Hydrogen as a fuel source
- By team domination
- (Wyatt, Nick, Jared, and Eugene)
2What is Hydrogen power?
- Hydrogen is harvested from the process of
electrolysis and used either in chemical
processes to create electric energy, or burned in
hydrogen combustion engines Ex BMWs hydrogen
powered v12(slide 7)
A model of an internal combustion engine(almost
the same as a hydrogen engine, but with different
timing and pressure ratios, and of course more
pollution) can be found at http//auto.howstuffwor
ks.com/engine1.htm
A detailed explanation of the chemical process of
using hydrogen to create electricity can be found
at http//www.cleanfuelcellenergy.com/Hp35p42.pdf
3Advantages
- Renewable if produced with solar energy
- Easy to use in cars, industry, homes etc
- Lower flammability than gasoline (less hazardous)
- Only emissions are in the form of water vapor (no
greenhouse co2) - Non toxic
4Disadvantages
- Non renewable if created with nuclear power or
fossil fuels - Requires large fuel tanks for storage
- Our current infrastructure is not designed to
use/ distribute hydrogen - New engine technology needed for use
- Currently expensive
5Issues
- It takes energy/ money to produce hydrogen
- It currently takes more money to create hydrogen
fuel than the fuel is worth - The good news is that scientists are making
rapid progress, and will likely be able to make
cost effective hydrogen fuel in the near future.
6The future of hydrogen
- The first widespread use of hydrogen will
probably be to combine it in small quantities
with other fuels like gasoline and natural gas to
reduce emissions and stretch reserves. - Next, as hydrogen technology improves, we will
likely see the emergence of hydrogen fueling
stations, and the adoption of hydrogen as a
primary fuel in first the commercial, and then
the private sector.
7Hydrogen combustion, BMW V12
- An article on BMWs new hydrogen powered V12
offers an example of hydrogen technology that has
already been developed - The article is about how hydrogen is soon going
to become a fuel source, and one of the early
leaders is BMW with their Hydrogen 7 with a V12
engine. Hydrogen is currently very difficult to
capture, transport and store, however one of the
benefits of such engines are their very low
emissions fuel source. Emissions are so low that
the test beds are not able to detect them. On
most test sites the new V12 even cleans the air
around it by emitting exhaust that is clearer
than the air it takes in. Hopefully such
technology will soon be able to help us off of
our current dependence on oil. -

8Holland Hydrogen Tractor
-
- Another encouraging example of hydrogen
technology comes from the Dutch, in the practical
form of a tractor. - An article about the new tractor in Holland
explains that it is 100 emission free all the
time. The NH2 (prototype name for the tractor) is
a nice relief from the super fast, super
efficient, super expensive cars that are going to
be the available in the next decades. The
hydrogen engine produces 106 horsepower and can
run for 2 hours on a tank. The plans are to have
the tractor come out within the next 3 years
commercially, and hopefully with slightly
improved operating time. The tractor is going to
be the starting point for a new fleet of hydrogen
fueled work sources that will patrol the Dutch
countryside. - The article in its full context can be found

9Hawaii Hydrogen Highway
- Article in its full context at
- http//www.fuelcellsworks.com/Supppage9620.html
- The article linked to above talks about the new
Hydrogen Highway that the army is working on
with the Hawaii Natural Energy Institute and the
Environmental Protection Agency. The Hydrogen
Highway is a government environmental
initiative, which will be a road on the main
island dotted with enough hydrogen fueling
stations to make travel by hydrogen powered
vehicle feasible. So far a hydrogen fueling
station has been planned at the Hawaii Volcanoes
National Park, and a few others are in the
drawing stages for locations on Hawaiis main
islands. The people of Hawaii are looking to turn
to hydrogen first as a fuel for government and
millitary vehicles, and then for private vehicles
also to decrease their use of foreign oil/gas.
10Hydrogen Locomotive
- An article about BNSFs hydrogen locomotive
project explains the benefits of introducing
Hydrogen as a fuel for their trains. - This article talks about a hydrogen-powered
locomotive which is a testing object that will
attempt to reduce the use of diesel fuel in the
world and in favor of moving to an alternate
source of energy such hydrogen which can be
produced from water. The NA train set up uses
about 15 trillion gallons of gas and the US is
trying to cut down that number and shift the
industry to renewable, less polluting fuels.
With diesel prices going up (they jumped to 26
of BNSTs operating costs last quarter) the
company is eagerly looking to develop new fuel
technology, and cut costs. -

11Current Commercial Hydrogen
- A company called HEC markets their current
hydrogen engines and generators at
http//www.hydrogenenginecenter.com/ Their add
talks about the history of hydrogen powered
engines and how they came to be. It also talks
about what all hydrogen engines can produce and
how they work. Their technology uses hydrogen
fuel to generate electricity, and they use the
zero emissions as a big sell point.
12Hydrogen as a viable alternative
- An article about the future of fuel explains that
when the oil dries up their will likely be many
different fuel options, and that one wont
immediately prevail. The main problems with
hydrogen right now seem to be that it is too
expensive to compete with fossil fuels, and that
our infrastructure isnt currently set up to
support it. This article explains however, that
once the price of hydrogen is brought down, it
will be a competitive alternative fuel. Due to
hydrogens high energy concentration, it would
only need to come down to eight dollars a gallon
to compete with gasoline, because it contains
more than twice the energy per kilogram as gas. - Article in its full context at

13Hydrogen from ethanol
- A recent scientific article offers hope for
solving the hydrogen harvesting problem. One of
the reasons hydrogen is not yet considered a
feasible fuel is that it is usually harvested
through electrolysis, which is expensive.
Professor of chemical engineering Lanny Schmidt
has developed a chemical reaction which can
cheaply harvest hydrogen gas from ethanol
(alcohol generated from biomass). This is
exciting because it may offer an affordable way
to produce hydrogen from a renewable source, and
Schmidt estimates that three times the energy can
be captured from ethanol hydrogen, than just from
simply burning ethanol. - Article in its full context at

14Hydrogen Boosted Engines
- an article about hydrogen boosted gasoline
engines talks about how they work and how
efficient they are. It discusses how small
amounts of hydrogen can be harvested from
gasoline by a car, and how cars with such engines
can gain an additional twenty to thirty percent
of their original fuel economy. In a hydrogen
boosted gasoline engine, a small amount of
hydrogen is made by an onboard reformer, and that
hydrogen is added to the normal intake mixture to
increase combustion efficiency. - The article in its full context can be found at

15Learning About Hydrogen
An electrolysis demonstration can be prepared
relatively easily. If you mix salt with water (to
increase its conductivity) and run wire from the
positive and negative electrodes of a 9 volt
battery into the water, you will see bubbles.
These bubbles are hydrogen and oxygen gas which
result from the decomposition of H2O. The wire
with more bubbles will be hydrogen as there are
two hydrogen atoms for every oxygen.
16Key Questions To Consider
- Can Hydrogen be harvested and stored cheaply
enough? - What changes would we have to make to convert our
infrastructure to hydrogen? - Can we get enough hydrogen from renewable
sources? - What is the timeframe for converting to hydrogen?
- Is it worth the RD to develop Hydrogen?
