Concentrating solar power (CSP) uses mirrors to focus sunlight and convert it to heat that can power a generator. There are four main types of CSP systems: parabolic troughs, solar towers, dishes, and linear Fresnel reflectors. CSP provides clean, renewable energy and can integrate thermal storage to provide power when the sun is not shining. While CSP currently has higher costs, these are expected to decrease as the technology matures and deployment increases. The document discusses India's plans to develop CSP through demonstration projects and evaluates CSP's potential to contribute to the world's energy needs in the future.

3. Concentrating Solar Power (CSP) is electricity
generated from mirrors to focus sunlight on to a
receiver that captures the sun’s energy and converts it
into heat that can run a standard turbine generator or
engine.

5. • Clean, reliable power from domestic
renewable energy
• Operate at high annual efficiencies –
Firm power delivery when integrated
with thermal storage
• Easily integrated into the power grid
• Boosts national economy by creating
many new solar companies and jobs

3)Dish Engine
4)Linear Fresnel Reflectors

7. Parabolic trough systems consist of parallel rows of mirrors
(reflectors) curved in one dimension to focus the sun’s
rays. The mirror arrays can be more than 100 m long with
the curved surface 5 m to 6 m across. Stainless steel pipes
(absorber tubes) with a selective coating serve as the heat
collectors.

8. Solar towers,also known ascentral receiver systems (CRS),use
hundreds or thousands of small reflectors(called heliostats)to
concentrate the sun’s rays ona central receiver placed a top a
fixed tower. Some commercial tower plants now in operation
use DSG in the receiver; others use molten salts as both the heat
transfer fluid and storage medium.

9. Parabolic dishes concentrate the sun’s rays at a focal
point propped above the centre of the dish. The
entire apparatus tracks the sun, with the dish and
receiver moving in tandem. Most dishes have an
independent engine/generator
(such as a Stirling machine or a micro-turbine) at the
focal point. This design eliminates the need for a
heat transfer fluid and for cooling water.

10. Linear Fresnel reflectors (LFRs) approximate the parabolic shape of
trough systems but by using long rows of flat or slightly curved
mirrors to reflect the sun’s rays onto downward-facing linear, fixed
receiver. A more recent design, known as compact linear Fresnel
reflectors (CLFRs), uses two parallel receivers for each row of mirrors
and thus needs less land than parabolic troughs to produce a given
output

11. Energy Payback (Input vs. Output) – The energy
payback time of CSP systems is about 5 months.
Greenhouse Gas Mitigation – CSP power plants
generate significantly lower levels of greenhouse
gases and other emissions.
Toxic Emissions – CSP is clean, non-polluting, and
has no carbon emissions
Health & Safety – The health and safety risks
associated with CSP power plants are the same for
any power plant.

12. Although CSP currently requires higher capital
investments than some other energy sources, it
offers considerable long-term benefits because
of minimum fuel costs for backup/hybridization.
Moreover, initial investment costs are likely to
fall steadily as plants get bigger, competition
increases, equipment is mass produced,
technology improves and the financial community
gains confidence in CSP. In the near term, the
economics of CSP will remain more favourable for
peak and intermediate loads than for base loads.

13. This roadmap foresees a rapid expansion of CSP
capacities in countries or regions with excellent
DNI, and computes its electricity production
as progressively growing percentages of the
overall consumption forecast in IEA climate
friendly scenarios in these regions .
In neighboring but less sunny regions, a lower
contribution of CSP electricity is expected, which
mixes local production and electricity from
nearby sunnier areas.

15. The Jawaharlal Nehru
National Solar Mission
recognizes CSP as a key
source of renewable power.
The ministry of new and
renewable energy is setting up
a string of demonstration
projects. A 10 mw CSP plant
is already under construction
near Bikaner by ACME, a
private company.

16. As the world's finite supplies of traditional fossil fuels
are consumed at a voracious rate by a continually
industrializing world, the development and use of non-
conventional sources of energy is becoming ever more
important for the future of the planet.so CSP is a
promissing technology for future development in power
sector.
