As time moves one and technology advance, we are using
more and more power for this technologies. Those new powerful devices however
efficient soak up more power than zero devices would, and our main sources of
energy are finite to begin with. At some point we will need to find cheap and reliable
source of energy. Some of reliable source of energy is hydrogen.So far the dominant technology for direct production
of hydrogen is steam reforming from hydrocarbons although there are many other
methods known including electrolysis and thermolysis.
A team of Virginia Researchers have found the way to
extract significant amounts of hydrogen from any plant, setting up a new source
of environmentally friendly energy. The method was carefully planned and theorized
for years. The team uses xylose which is an abundant sugar found in plants.
This component is sometimes a part of a substance that composes over 30% of
certain plants. Xylose is the second most abundant sugar in plants, and from it
the team managed to generate a sizable amount of hydrogen from it. The team
that proven this revolutionary idea didn’t reveal much but they said that the
method is relatively safe for environment, as barely produces greenhouse gas
and doesn’t require the use of expensive metals.
Before this discovery the production of hydrogen from
biomass wasn’t impossible but the process was too expensive and amount of
resulting oxygen was too little. What the team revealed was that for this new
production of hydrogen you need: enzymes from microorganisms, mixture of these
enzymes together, combine the mixture of enzymes with the xylose and a
polyphosphate. Once the mixture of enzymes, xylose and polyphosphate are mixed
together the team is able to extract hydrogen. The one big condition is necessary
for this procedure that is low temperature. With low temperature scientists
have discovered that you can increase efficiently of this hydrogen production.
This procedure is so efficient because the team was able to achieve 100% net
gain of energy, which means that you don’t lose any energy when you produce the
hydrogen.
The team plans to make this technology commercially available
whenever the method is refined enough for the open market which will be after
three or more years.
