2. Concentrating solar power
technology
Types of csp:
1. THE TROUGH SYSTEM
2. POWER TOWER SYSTEM
3. DISH/ENGINE SYSTEM

3. TROUGH SYSTEM
● comprises of U-shaped reflectors
focussing sunlight onto pipes
running along their centre
● These pipes are filled with oil or
molten salt
● The heated oil in turn heats the
water into steam

4. SOLAR POWER
TOWER
● uses large flat mirrors called
heliostats to focus sun rays
onto a receiver sitting atop a
tower
● In top of the tower fluid such
as molten salt is present
● A part of molten salt is
stored for future use

5. DISH/ENGINE
SYSTEM
● use a parabolic dish of mirrors to direct and
concentrate sunlight onto thermal receiver
● Thermal receiver is filled with cooling
fluid(heat transfer medium
● The engine uses heat from thermal receiver
to move pistons and create mechanical
power

6. Advantages
of csp
● Overcome problem of
intermittency
● The equipments used for
conventional fossil fuel
power plants can be used

7. Floating
wind
turbines
● Wind turbines which are anchored to
the seabed by means of flexible
anchors, chains or steel cables.
● A floating offshore wind platform
(FOWP) is the concrete, steel or
hybrid substructure on which the wind
turbine is installed, providing it with
buoyancy and stability
● The produced electricity is
transported through underwater
cables to a offshore substation

8. Advantages of floating wind
turbines
Energy efficiency: strong wind in deeper
area means greater efficiency
More dependable : it becomes a more
dependable energy source because of
constant winds of deeper waters

9. beta voltaic cell
● Electron is generated by a radio active
source( beta emitters)

10. Beta voltaic cell
● Electrochemical batteries dont
last very long
● Nuclear batteries can last up to
decades
● Low energy particles can easily
be contained
● Can be used in scalable, long-
lasting, low-power devices
● Eg : pacemaker cochlear
implant

11. Printable solar
cells
● Paper thin solar cells
that can be produced
with inkjet printing on a
sheet of paper.

12. Advantages
● Cheap than traditional ones.
● Energy can be harvested anywhere
curtains walls
● Converting silicon into wafers is expensive

13. disadvantages
● Efficiency is only 10 percent
● Life time is less

14. Microbial fuel cell
A microbial fuel cell (MFC) is a device
that converts chemical energy released
as a result of oxidation of complex
organic carbon sources which are utilized
as substrates by microorganisms to
produce electrical energy thereby proving
to be an efficient means of sustainable
energy production.

15. ADVANTAGES
● Could encourage waste water
treatment
● Deriving energy from useless
sources
● Reduces the energy consumption
for wastewater treatment
● Avoiding the use of expensive
catalyst
