No scrubbers that soak up carbon dioxide, that I've ever heard of. Except the bio alga fuel project.
I went on a sales call a month ago to a Seattle based company with about the dumbest business model I've ever heard. They are making special pumps that will capture CO2 emmissions from manufacturing plants etc and they'll store the compressed gas in tanks that are buried in the ground instead of releasing it into the atmosphere.
It took me everything I had from busting out laughing. Every one there should start looking for a new job!
