“Green coal-fired power” labs would be used for research as intermediate testing
systems, such as technologies producing and storing H
2
with gas, technologies of
separating H
2
and CO
2
, technologies of sealing, storing and using CO
2
, for
generating power from fuels and batteries, technologies of H
2
fueling machines
to prepare for a demonstration program of the third phase.
Third phase (2014-2016): To carry out the “green coal-fired power” demonstra-
tion project.
In 2016, “green coal-fired power” demonstration programs at the 400MW level
would be established for large-scale technologies that produce H
2
from coal,
generating power from H
2
, gathering, sealing and storing CO
2
are integrated.
Coal energy is produced more efficiently with zero-emissions of pollutants and
CO
2
. Meanwhile technological reliability and economic feasibility of “green coal-
fired power” systems prepare for commercialization.
5.1.1.3 Improving Thermal Power Generation Efficiency
Table

displays the index for efficiency of the main energies of China's power
generation sections from 1980 to 2010. National's coal consumption for power
generation, coal consumption for provision and proportion of power consumption
by thermal power plants have been decreasing for a long period.
By 2009, national total installed capacity and power generation reached 874
million kilowatts and 3.68 trillion kwh respectively.
The standard average coal consumption of the nation's 6,000-kW and over-
6,000-kW thermal power sets for power provision was 340 g/kwh, decreasing by
5 g/kwh over the same period last year; loss rate in circuits was 6.72 %, decreasing
0.07 % over the same period last year.
