Green House Gas level rise to a current level of 390
ppm and consequent climate change, floods and
draughts has affected 260 million people between
2000 and 2004 through natural calamities, of these,
98% were in developing nations.
Developed countries with population of 15% of
world population have the share of CO2 emissions at
50%.
CO2 level has risen to 390 ppm from 1975 level of
330 ppm.
There is so much
momentum in the system that
we will certainly double CO2 level by end of the
century.
Global temperature rise by 3 to 4 0C will cause
displacement of over 330 million people in
developing world.

China and India are projected to account
for 30% of the world’s
increase in
energy consumption between 2000-2020
and 92% of increase in coal use.
World Green House inventory is over
29,000
Million
tones
per
annum
(MTPA) with US over 20% (India with
total emission of about 1400 MTPA is
only at 4.8 %.)
Coal is going to remain main stay for
power generation in at least next Three
decades for India (87,093 MW Coal
based generation out of 1,63,669 MW
total power installed capacity)

Can we address the following
issues by roping in renewables?



GDP growth must be sustained and lack of
energy availability should not pull it down.
Exchange crisis should not recur due to
bulging Oil import bills
Climate change is a concern and countries
with low per capita income are more
vulnerable to the effects of climate change
The answer seems to be ….yes.

The National Solar Mission is a major
initiative of the Government of India
and State Government to promote
ecologically sustainable growth while
addressing India’s energy security
challenge.
It will also constitute a major
contribution by India to the Global
efforts to meet the challenges of

….Reference: Address by President of India 14th Aug 2005
“We conclude that CO2 capture and sequestration (CCS) is the critical enabling technology that would reduce CO2
emissions significantly while also allowing coal to meet the world’s pressing energy needs.” – MIT 2007
“Citizens of poor countries have the right to aspire to better standards of living… clean coal is key.” – Arun
Ghosh, Global Economic Fellow, Oxford University
“For decades, the coal industry has supported quality high-paying jobs for American workers, and coal has provided an
important domestic source of reliable, affordable energy…. Charting a path toward clean coal is essential to achieving my
Administration’s goals of providing clean energy…” – President Barack Obama, 2010

Objectives of the Proposal:
1. To establish a pilot plant for CO2 sequestration and
conversion in to multipurpose fuel.
2. To develop Zero Emission Technology Projects and
recycle Carbon-di-oxide to add value to clean energy
projects by adopting two pathways:
 Sequester CO2 and convert the same into fuel molecules.
 Use CO2 to grow micro algae to produce Bio-diesel and
Methane Gas.
3. To develop mathematical & chemical models for CO2
sequestration, Hydro Gasifier, Catalytic conversion

THE ROAD MAP



Government of India has declared its policy on
CO2 abatement by the announcement and
adoption of the ‘National Action Plan on
Climate Change’.
It has also made voluntary commitment at the
Copenhagen Summit that the Country shall
decrease its Carbon Intensity by 20% by 2020
and 50% by 2050.
The bulk of CO2 is emitted by the Thermal
Plants in the Power Sector. For EPA
regulations to be implemented there have to
be a road map as to how this can be done
without major impact on the cost or efficiency
of the Thermal Plants
Solution lies in…


The thermal plants in India have a thermal
efficiency of 35% and an emission ratio of
0.90Kg/kWh of CO2 emissions as published
by CEA. The reduction of 20% intensity
would
translate
to
a
decrease
of
0.20Kg/kWh of CO2 emissions i.e. below
0.70Kg/kWh CO2 emissions by 2020.
This decrease is possible by a combination of
abatement and recycling measures. The CO2
reduction by an Amine system of 30% CO2
capture would mean a decrease of Thermal
Efficiency by 2%
Application Potential:
Long Term
• Deployment of the Technology to Actual Power Plants of NTPC
through BHEL / TOSHIBA or any other major player
Immediate
• Green Energy Technology Centre (GETC) being set-up for Teaching
& Research (M. Tech & PhD)
Future action plan:
Efforts are underway to extend the scope of the process by
incorporation a Coal gasifier and recycling of carbon through
collaborative research and Distributive Research Initiatives (DRI) with
Research Organizations and Power Industries.
Carbon Capture & Sequestration
•
•
India’s position with regard to Carbon
Capture & Storage (CCS) is very clear. We
don’t make any commitment at this stage
regarding deployment of CCS technologies.
India advocates very strongly the Carbon
Capture & Sequestration.
Some of the demo pilot projects include.
-Pilot project on Geological CO2
sequestration
in basalt rock formation.
The question of adoption of CCS will depend
on this
technology being cost effective.
-Projects under DST sponsored National
Program on
Carbon
Sequestration
(NPCS)
