Jeff Johnson has a nice article in the
July 16 issue of Chemical & Engineering News entitled, "Stumbling on the
Path to Clean Coal". The subtitle is, "Carbon Capture and Sequestration appears
stuck, dashing hopes of cutting CO2 while burning coal".
The dictionary
has only two definitions for "sequestration". The legal definition is the
seizure of property. The chemical definition is the limitation or prevention of
normal ion behavior by combination with added materials. However, a new
definition has developed, which is the process of removing carbon dioxide from
the atmosphere. Note that these definitions are different from the
"sequestration" denoting mandatory cuts in government expenditures on January
1.
We should also look at recent use of the term "clean coal".
Previously, clean coal had a meaning of form of relatively pure carbon. That is,
it had little or no contamination from sulfur or mercury. When the term is now
applied to coal, meaning no carbon dioxide emission on burning, it is obviously
an unrealistic interpretation of the English language. There is no carbon
dioxide in coal, and therefore coal cannot be significantly contaminated by
carbon dioxide.
In spite of these difficulties with language, the total
article gives good news. While the House of Representatives cleared legislation
to require carbon dioxide reductions to the atmosphere and a Cap & Trade
program in 2009, a price on carbon dioxide emissions expired the next year. Jeff
says that today Congress members have no intention of putting a price on carbon
emissions and many even challenge the scientific basis of climate change. That
is wonderful news, because there is absolutely no basis that carbon dioxide
emissions to the atmosphere cause any damage to the environment, and any
attempts at major control would be horrendous.
Unfortunately, the
Department of Energy does not give up easily, even when it's wrong. It has
provided $6.9 billion for R&D funding on carbon sequestration since 2005,
and half of that has come from the American Recovery and Reinvestment Act of
2009, which was President Obama's stimulus package.
A subsequent report
by the Congressional Budget Office also states that carbon dioxide each
sequestration would increase electricity costs from coal-fired power plants by
75%, because of the cost of new equipment for CO2 capture.
Organizations,
such as the Congressional Research Service and the World Watch Institute "find
a" great need for carbon sequestration. There is no indication as to why this
would be necessary, and we can only assume that this would be the usual
complaints of Marxist type environmental organizations.
Jeff goes on to
say that the use of natural gas and electricity production has increased, with a
consequential reduction in the use of coal. However, coal gives one third of the
US total CO2 emissions and 80% of the CO2 emissions from electricity production.
So what? There is no evidence that atmospheric carbon dioxide increase is
detrimental to the environment.
Robert Hilton is a vice president of
Alstom, a global construction and engineering firm supplying equipment for
carbon dioxide capture. He bemoans the trend in Congress toward realization that
carbon dioxide capture from coal burning plants is not necessary. Naturally so,
it is his business to supply such equipment. However, it is clear that Alstom
was not willing to put its money where its mouth is. It rejected an offer to put
up only half of a $668 million project to sequester carbon dioxide in a West
Virginia electric power plant, with the Department of Energy putting up the
other half in taxpayer money.
However, a negative shadow on the situation
is that the EPA has proposed a new rule to limit CO2 emissions from new power
plants to 1000 pounds per megawatt hour. Since the present technology for new,
coal-fired power plants would have emissions of 1650 to 1750 pounds of CO2 per
MWh without carbon sequestration, it appears that no new coal-fired power plants
will be built, unless Congress takes further action to control the EPA's abuse
of power.
