Hydrogen
Hydrogen is The most abundant chemical element in our universe. it combines about 75 % of the normal matter.What is the Hydrogen (H2)?
Hydrogen is the first element in the periodic table where elements are arranged based on their atomic number, electronic distributions, and chemical properties. Its symbol is H and its atomic number is 1What are the Hydrogen properties?
The properties of Hydrogen are that it is a non-toxic gas under the
standard test condition (STC) which is at standard values of temperature
(293K and 20 °C), pressure (1 atm), and humidity (0), a chemical substance composed of
two of the same elements with an H2 formula. It is odorless, colorless,
and tasteless. It is also lighter than air rather than the lightest
element. It is flammable can catch fire easily by any other flame, and is
insoluble in water.
Normally Hydrogen is a non-metallic element but, at very high extreme
pressure, it turns metallic. The Hydrogen atom includes one positive
charge which is the proton in the nucleus and an electron as a negative
charge and it has no neutrons. Hydrogen could be represented in many forms
other than gasses and metallic. It could be in the form of a liquid,
slush, solid, or plasma.
What is the history of Hydrogen?
Hydrogen gas existed at the beginning of the universe when the Big Bang
happened. Earth is very rich in Hydrogen in the form of water in oceans,
lakes, and rivers. Hydrogen also exists in all organic compounds
vegetables and animal tissues which have Carbon-Hydrogen bonds. Also, the
Hydrogen is present in petroleum products. The first production by humans
started at the beginning of the 16th century. In the 17th, it was used to
produce water from Hydrogen when it was burnt in the presence of Oxygen.
The name of Hydrogen is deducted from water formed which is Hydrogen in
Greek.
What are the types of Hydrogen?
1- Grey Hydrogen:
Grey Hydrogen is the Hydrogen produced from splitting the methane element
into Hydrogen and CO2. It also can be produced from coal. It produces a high
amount of CO2 which is the main reason for climate change. That is why it
may be called brown or black Hydrogen. It is also produced industrially
2- Blue Hydrogen:
is the Hydrogen produced from fossil fuels such as natural gas and oil
reforming process called gasification. In the gasification process,
synthesis gases are a group of gasses that combine Hydrogen, carbon
dioxide, and carbon monoxide and are produced by the reaction of natural
gas with steam having a very high temperature. During this process, the
produced CO2 is captured by special and modern technology and
processes and stored to decrease the emission of CO2.
3- Turquoise Hydrogen.
It is a process like the grey for Hydrogen production from splitting the
methane but, it uses technologies to maximize the produced CO2 and increase the storing time as much as possible. It
could catch about (90-95%) of CO2 as a solid and long-term storage.
4- Green Hydrogen.
Green Hydrogen is the Hydrogen produced by using a
renewable energy
source to split the water into oxygen and Hydrogen. It collects the
advantages of renewable sources such as availability and low co2 emission.
What are the advantages of Hydrogen?
1- Hydrogen is a renewable energy source.
In the electrolysis process, if the electrical power used to split water
into Hydrogen and Oxygen was generated from renewable sources like solar
cells and wind power generators, the produced Hydrogen then will be
considered as a renewable element.
2- No CO2 emissions when used in electricity generation.
When using Hydrogen in electricity generation it also produces water as a
by-product with no carbon dioxide CO2 emission. Which is considered an advantage over fossil
fuels in electricity generation in boilers and gas turbines.
3- High energy density
Hydrogen produces water and generates heat when it combines with oxygen in
the presence of flame. leases heat. The development makes it easy to deal
with Hydrogen and make it one of the highly efficient energy-density
element.
4- Hydrogen can be stored
When using renewable energy sources for Hydrogen production like
solar cells
or wind turbines, the produced Hydrogen quantity is stable depending on
the weather conditions so an important advantage of Hydrogen is that it
can be stored in good weather or by non-renewable energy to be used at the
time bad weather.
5- Hydrogen can be used in heavy industries as a fuel.
Hydrogen could be used in heavy industrial manufacturing like glass and steel manufacturing processesin combustion chambers. but this process considerably has low efficiency and causes high levels of emissions.
6- Good potential for investment
The development and improvement of the production of Hydrogen as well as
the the renewable energy sources in Hydrogen production make it a good
investment in power generation large-scale projects.
7-Sustainable and promising fuel.
As Hydrogen has been used in electricity generation since the 19th
century, it is considered stable and dependable and we can let it never
run out depending on its availability. Because of that and its advantages
and performance, it could be easily used in space rockets and spacecraft.
How does the Hydrogen be transported and distributed?
1- Liquid Hydrogen Tankers.
in this process, Hydrogen is cooled first to a certain value of
temperature making the Hydrogen in the liquid state. The Hydrogen
transportation in that process is more efficient when we compare it with
the high-pressure tube trailer because it could be used for long distances
although it is more expensive. This process has a disadvantage such as
that the liquid Hydrogen will be evaporated if it is not used at the exact
time when it reaches its final destination otherwise, the Hydrogen will be
lost.
2- Hydrogen pipes.
are the cheapest method for Hydrogen transportation and distribution in
the pipelines where a large volume of Hydrogen can be transported or
distributed. The main disadvantage of that way is that we cannot transfer
large capacity through it.
3- High-Pressure Tankers
the high-pressure tube trailers examples used for Hydrogen Transportation
and distribution examples could be represented as railcars, trucks,
barrages, and ships. This process is very expensive and is suitable for
short distances (about 200 miles) miles or less.
What are the applications of Hydrogen?
The Hydrogen element is used in many applications because of its advantages. These applications could be listed as follows:- Hydrogen is used in power generation plants to produce electricity by firing the plant with Hydrogen instead of natural gas.
- Hydrogen is used as a fuel in space rockets and spaceships.
- It is used in Hydrogen fuel cells in hybrid cars.
- It is chemically used in fertilizer manufacturing.
- Hydrogen is used in petroleum.
In the next articles, each application from these applications will be
explained in detail
