The most promising
option for hydrogen production from renewable resources is water electrolysis. It
is a process that uses electricity to split water into oxygen and hydrogen.
This process takes place in a unit which is known as an electrolyzer. Ranging
from small, appliance size units to large scale units, electrolyzers are
well-suited for central production facilities that could be tied directly to
renewable or other non-greenhouse-gas-emitting forms of electricity production.

Electrolysis of Water
Water
electrolysis is a process in which water is decomposed to give oxygen and
hydrogen gases due to the passage of electric current through it.
The most
plentiful element available in the Universe is Hydrogen but the gaseous state
of hydrogen has to be manufactured as it does not naturally occur on Earth. To
produce H2 in an extensive amount, industries use a process called steam
reforming that separates hydrogen and carbon atoms from hydrocarbon fuels.
H2 is widely
used in the laboratory for applications like Gas Chromatography as a fuel or
carrier gas and ICP-MS as the collision gas. It is also used in the chemical
industry to synthesize methanol, ammonia, and cyclohexane. In the food
industry, it is used for hydrogenation of oils to form fats.
Working of water electrolysis type
Hydrogen Generators
Electrolysis
of pure water is an extremely difficult process but it is the best method to
produce high-purity hydrogen.
The
principal element of water electrolysis type hydrogen generator is the
electrolyzer where the electrolysis reaction takes place. In the electrolyzer,
there are two electrodes known as a cathode and an anode. These electrodes are
separated by the ion exchange membrane. When electricity is supplied to the
electrodes, these electrodes separate the source (water) into hydrogen and a byproduct that is not
utilized by the generator. By adding a small number of ions make the process
executes effortlessly. At maximum places, there are sufficient minerals in H20
that the conductivity of water or its iconic strength is adequate for the
effective occurrence of electrolysis without any requirement to add extra ions
to the water.

Benefits of Nitrogen Generators
Do you know that the major part of the air we breathe is Nitrogen?
Every living being on this planet needs oxygen to survive but oxygen is merely
21% present in the air. The biggest part of the air is nitrogen i.e. 78%, the
remaining part is tiny amounts of other gases. Although living beings do not
use this nitrogen it is extremely helpful in numerous industrial applications.

Oxygen generators for different kind of applications
On-site oxygen generators systems are
machines that let the users produce oxygen gas gor atmospheric air. O2
generators are based on Pressure Swing Adsorption technology and are used with
an end goal to provide oxygen in hospitals and other healthcare services. PSA
technology based oxygen generators are dependable and minimal effort systems
for all type of oxygen generation.

Nitrogen for food processes
Nitrogen gas has several uses
in retail food and services establishment. Its liquid form is used as a
freezing agent in food preservation as well as preparation of rapid freezing of
foods, to chill beverages rapidly and to process dry herbs. In the preservation
of frozen foods, where mechanical means are unavailable, dry ice is the best
thing to use. Liquid nitrogen and dry ice, both things are used for their smoke
effect in food & beverages to enhance the presentation and consumer appeal.
