I think we're just gonna have to remain in agreement we're gonna wait and see what develops. Meanwhile, below is some interesting reading on the subject, a subject way beyond my ken (I'm usually pulling guitar strings--lol!)
>>>Considerable chemical processing is needed to implement all of the post-combustion carbon capture processes that have proven their worth in the lab or at pilot scale and are now advancing toward commercial viability (POWER, October 2006, p. 60). Two processes that seem to have gathered the most steam in the marketplace are the chilled ammonia process favored by Alstom Power (see sidebar) and Powerspan’s Electro-Catalytic Oxidation (ECO) process, which was recently upgraded to include CO2 removal and relabeled ECO2. Powerspan and FirstEnergy Corp. plan to demonstrate the ECO2 process at a 1-MW (equivalent) pilot scale at the utility’s R.E. Burger plant in Ohio early this year (POWER, October 2007, p. 54).
There’s no doubt that Alstom is about to enter the flue gas treatment market; the company continues to fund an extensive R&D program whose target is to make a CO2 capture system commercially available before the end of 2011. The evolution of Alstom’s business development plans for its chilled ammonia systems has been transparent from the start:
* A 5-MW (equivalent) pilot plant with EPRI and We Energies.
* A 5-MW demonstration plant for E.ON in Sweden.
A 30-MW (equivalent) product validation unit for American Electric Power (AEP), followed by the design, construction, and commissioning of a commercial-scale (up to 200 MW) unit by 2011.
* A 40-MW (equivalent) product validation facility for Statoil in Norway.<<<

>>>As CO2 emission control is gaining increasing acceptance, efficiency improvement, as the only practical tool capable of reducing CO2 emission from fossil fuel plant in the short term, has become a key concept for the choice of technology for new plant and upgrades of existing plant. Efficiency is also important for longer-term solutions of reducing CO2 emission by carbon capture and sequestration (CCS); it is essential for the underlying plants to be highly efficient so as to mitigate the energy penalty of CCS technology application. Power generating options, including coal-fired Rankine cycle steam plants with advanced steam parameters, natural gas-fired gas turbine-steam, and coal gasification combined cycle plants are discussed and compared for their efficiency, cost and operational availability. Special attention is paid to the timeline of the various technologies for their development, demonstration and commercial availability for deployment.<<<
