several years ago but canceled in
when costs greatly
increased, was the wrong program because it tried to do
too much too soon. If I was running the program I would
have had an existing coal plant equipped with the best of
the post-combustion CO separations technology to test
it out. I also would have supported a test of pre-
combustion separation of oxygen from the nitrogen in
the air. Finally I would have a program of CO injection
into the deep saline aquifers to see what happens to it.
Conversion of old coal plants to modern gas plants
reduces emission to one-third of the original coal plant
emissions for the same electric power generation. Part of
the reduction comes from the fuel switch and part comes
from the higher ef
red power plants.
This should be encouraged, but somehow it doesn
ciency of the gas-
t seem
to have the emotional attraction of renewable energy,
though it is much less costly, and can be done on a very
much larger scale than solar power.
More emission-free electricity can come from nuclear
power plants or from the renewables. These are the sub-
ject of later chapters.
