As I keep pointing out, that is not probable. A pilot plant is not to

whether the technology works, but whether it works the same way on a

the
technology to work, as it would mean that all the protests were
pointless.

Wrong, there is plenty more to protest about,

That does not change the fact that the past protests would turn out to have
been pointless

"Capturing and compressing CO2 requires much energy and would increase
the fuel needs of a coal-fired plant with CCS by 25%-40%.[1] These and
other system costs are estimated to increase the cost of energy from a
new power plant with CCS by 21-91%."

I can't check the figures, as you haven't given the source (again), but they
sound highly dubious. Compressing gas is cheap, which is why compressed air
is used as a power source in industry. However, if cost is the only factor,
wind energy would be a non-starter with electricity from onshore wind farms
costing up to 2.4 times as much as from a gas fired or fluidised bed coal
station and that from offshore farms costing up to 3.3 times as much. - EU
survey 2007 not available online SFAIK

So, try it and see if it really works and THEN build new coal-fired
power stations. Not the other way around.

As I have pointed out, you can't build infrastructure that way. We need to
build what is possible now to meet future needs, not wait until we run into
energy shortages because something better is on its way.
