This presentation summarizes different types of energy storage technologies, including thermo-mechanical, electrochemical, and electrical storage. Thermo-mechanical storage discussed flywheels and pumped hydro, with pumped hydro storing potential energy by pumping water between reservoirs. Electrochemical storage reviewed vanadium redox flow batteries, zinc-bromine flow batteries, and lithium-ion batteries. Electrical storage examined supercapacitors and superconducting magnets, with supercapacitors charging much faster than batteries but having a shorter lifespan. The presentation provided advantages and disadvantages of the different energy storage methods.

3. ENERGY STORAGE Introduction
Energy storage is the retention of energy produced at a
specific time with the aim of utilizing it at a later time.
3
Advanced energy storage provides an integrated
unit and solution to some energy problems
As it enjoys reliability, flexibility, sustainable
mobility, safe, comprehensive, economic
enhancement, and the competitiveness of remote
communities.
Storage technologies strengthen and stabilize
power grid coils by providing backup power.

4. Typesofenergystorage:

Thermo-mechanical electricity
storage
Such as :
1. Fiywheel
2. Pumped hydro

5. Flywheel method

6. Advantages
1.Low maintenance.
2. Long life (some flywheels are
capable of well over 100,000
full depth of discharge cycles ).
3. Low environmental impact.

7. Pumped hydro
7
● storing potential energy by pumping water from a lower to a higher level.
●To return power to the grid, the water flow is reversed and used to drive
turbines.
●In practice, the same machines – reversible pump-turbines – are used for both
phases of operation.
●. Storage at both upper and lower levels takes the form of open reservoirs.
●PHS is characterised by relatively high efficiency (up to 80%) .
●The volumetric capacity depends mostly on the height difference between the
two reservoirs.

18. Zinc-bromine Gel Battery
18
Gelion ENDURE, the first Zinc-bromine gel
battery was invented at the University of
Sydney by Professor Thomas Maschmeyer,
which was launched in 2019. They were first
used to power mobile light towers at the
University of Sydney. The battery is in
essence, a stack of small discs that can be
added together to form a bigger battery.
Gelion is focused on entering the market as
an innovative battery alternative for primary
energy generation. With mass
manufacturable designs and pilot
deployments aimed to commence in 2020.

19. Lithium Ion Batteries
19
Advantages :
 Lithium batteries do not lack their capacity when
shipping operations
 High capacity intensity
 larger effort compared to other types of
batteries;
dissadvantage
 Its efficiency with increased age
 Several problems, especially on the safety hand;
these batteries tend to rise excessive rise, and
then they may be affected at high efforts, which
may result in thermal discharge or combustion

21. Electrical energy storage
21
Such as :
• Supercapacitor
• superconducting magnet

22. What is a Supercapacitor?
22
In short, supercapacitors are
high-capacity capacitors. They
have higher capacitance and
lower voltage limits than other
types of capacitors, and
functionally, they lie somewhere
in between electrolytic
capacitors and rechargeable
batteries.

23. Super capacitor structure:
23
Double-sided electrodes are made of
graphite carbon in the form of activated
conductive carbon, carbon nanotubes, or
carbon gels. A porous paper membrane
called a separator that keeps the electrodes
apart but allows positive ions to pass while
blocking out larger electrons. Both the paper
separator and the electrodes are
impregnated with carbon With the liquid
electrolyte using aluminum foil between the
two to act as a current collector that
conducts electrical conduction to the solder
tabs of the "supercapacitors".

24. What this means in practice is that they:
24
 Charge much faster than batteries
 Can store much more energy than electrolytic
capacitors
 Have a lifespan (measured in charge/discharge
cycles) somewhere between the two (more
than rechargeable batteries and less than
electrolytic capacitors).

25. Advantages and Disadvantages of
Supercapacitors
The benefits of supercapacitors
include:
1. Balancing energy storage with
charge and discharge times.
2. Wide-ranging Operating
Temperatures.
On the other hand, the speed of energy
exchange is, in some sense, a bug as
well as a flaw. Here are some
disadvantages of supercapacitors:
1. Self-discharge rate.
2. Gradual voltage loss.
25

26. Ultracapacitors
26
Ultracapacitor and supercapacitor are the
same thing Ultracapacitors are extraordinarily
well suited to any application that expects
frequent charge and discharge cycles,
extreme operating temperatures, or rapid
discharge of high amounts of energy. Here
are some exciting applications on the
horizon:
1. Public Transportation
2. Hybrid supercapacitor-battery. Extending
run times.
3. Power stabilization.

27. superconducting magnet
27
A superconducting magnet is just like a
regular electromagnet, except that
there is no resistance to electricity. If
it's a resistive coil, you're losing power,
and it's generating heat. There's no
heat generation here, so you're not
losing energy.

28. Advantages and Disadvantages :
28
Advantages :
• high efficiency
• fast response
• large power
• high power density
• long life with almost no loss
Superconducting materials
superconduct only when kept below a
given temperature called the transition
temperature.
Disadvantages :
