3. 1) HYDROGEN
 Hydrogen is the simplest and
most abundant element in the
universe. It consists of one
proton and one electron,
making it the lightest element.
It's found in various forms, such
as diatomic molecules (H2) and
ions (H+).

4.  Hydrogen is
crucial in various
processes,
including being a
component of
water (H2O) and
serving as a fuel
source in fusion
reactions.

5. 2) ELECTROLYSIS
 The process of producing green
hydrogen involves using electricity
from these renewable sources to split
water (H2O) through a process called
electrolysis. This process separates
the hydrogen and oxygen atoms in
water, generating hydrogen gas
without emitting carbon dioxide or
other greenhouse gases.

6.  Electrolysis is the technical
name for using electricity to
split water into its constituent
elements, hydrogen and
oxygen. The splitting of water
is accomplished by passing a
DC electric current through
water. The electricity enters
the water at the cathode, a
negatively charged terminal,
passes through the water and
exists via the anode, the
positively charged terminal.

7.  The hydrogen is
collected at the
cathode and the
oxygen is collected
at the anode.
Electrolysis
produces very pure
hydrogen for use in
the electronics,
pharmaceutical and
food industries

9. 3) ADVANTAGES AND
DISADVANTAGES
 A) Advantages:-
 Clean Energy Source: Electrolysis is considered a
clean method of hydrogen production as it only requires
electricity and water, resulting in no direct emissions of
pollutants or greenhouse gases.
 Renewable Integration: It can be powered by
renewable energy sources like solar or wind power,
making it a potential way to store excess energy when
these sources generate more electricity than needed.

10.  Flexibility: Electrolysis can operate at varying scales, from small
installations to large industrial setups, providing flexibility for different
applications.
 B) DISADVANTAGES
 Energy Intensive: Electrolysis requires a significant
amount of electricity to separate water into hydrogen and
oxygen, which can make it less energy-efficient compared to
other hydrogen production methods.
 Cost: The cost of producing hydrogen through electrolysis is
relatively high due to the electricity required.
