Assessment of greenhouse gas emissions from coal and natural gas thermal power plants using life cycle approach
Agrawal, K. Kr.; Jain, S.; Jain, A. Kr. & Dahiya, S.
Abstract
The importance of mitigation of climate change
due to greenhouse gas (GHG) emissions from various
developmental and infrastructure projects has generated
interest at global level to reduce environmental impacts.
Life cycle assessment may be used as a tool to assess GHG
emissions and subsequent environmental impacts resulting
from electricity generation from thermal power plants. This
study uses life cycle approach for assessing GHG emissions
and their impacts due to natural gas combined cycle
(NGCC) and imported coal thermal power plants using the
IPCC 2001 and Eco-Indicator 99(H) methods in India for
the first time. The total GHG emission from the NGCC
thermal power plant was 584 g CO2 eq/kWh electricity
generation, whereas in case of imported coal, it was
1,127 g CO2 eq/kWh electricity generation. This shows
that imported coal has nearly ∼2 times more impacts when
compared to natural gas in terms of global warming
potential and human health as disability-adjusted life years
from climate change due to GHG emissions such as carbon
dioxide (CO2), methane (CH4) and nitrous oxide (N2O).
