Title: By team domination


1
Hydrogen as a fuel source
  • By team domination
  • (Wyatt, Nick, Jared, and Eugene)

2
What 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

Advantages
  • 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

4
Disadvantages
  • 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

5
Issues
  • 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.

6
The 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.

Hydrogen 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.

Holland 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.

Hawaii 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.

Hydrogen 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.

Current 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.

12
Hydrogen 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.

13
Hydrogen 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.

Hydrogen 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.

15
Learning 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.
16
Key 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?
