IPCC WGIII Fourth Assessment Report, Second Order Draft
858 depends on a number of uncertain factors, such as the future
Carbon price and regulatory constraints. In some cases retrofitting
CCS may have attractive option value. Change text from "is
generally economically unattractive " to " may be less attractive".
As written the statement is in direct conflict with Chapter 4, pg 66,
lines 17-35, which defines a C-R plant as one that can economically
have capture added in the future and with practical experience of
utilities already starting to make plant designs capture-ready
specifically so that they can add capture in the future rather than
scrap the plant and build a new one.

14 A 12 14 12 19 The contents with bold are not consistent with the following
description. According to the contents in bold, we think that some
measures that enhance energy efficiency should be mentioned.
Also, for the short- to medium- period, it is not possible to use
commencially CCS technologies.

14 A 12 14 12 16 Replace "is generally economically unattractive" with: "may imply
extra costs pending on technology and location". Rationale: In
some cases retrofitting power plants with CCS may be done with
little extra cost while it can be more costly on other plants eg.
depending on the age of the facilities and the location.

14 A 12 14 12 16 replace "interest ... plants" with "interest in new power plants based
on clean coal technologies with the highest efficiency possible",
and add "unless new build plants are made capture ready" after
"economically unattractive"
(Government of The Netherlands)
14 A 12 14 12 14 "In this context….plants". Instead of the term "New coal power
plants", can a more specific term be used?
