CO2 Capture - What is the Holy Grail?

[altenergygeek]

Of the three steps in CCS - capture, transportation and storage - capture is by far the most costly (almost 70% of the total cost of CCS). So what could really bring the costs down?

Will they be new types of enzymes (see an [URL="http://powerplantccs.com/blog/2010/03/co2-solution-joint-development-with-codexis-with-enzymatic-method.html)"]interesting post on enzymes[/URL]for this) for making the CO2 capture process more efficient? Or will it be through better materials for capture? (see here for an[URL="http://www.azom.com/news.asp?newsID=25474"] interesting update [/URL]on this). Or could it be a better method of amine-based CO2 capture? Or could it be something radically different like [URL="http://www.powerplantccs.com/ccs/cap/fut/alg/alg.html"]using algae to capture CO2[/URL]?

What are your thoughts?
