I have yet to see a viable business model for any geoengineering company, but when one does come along it will definitely be Interesting Times.

Government subsidy.

Governments probably aren't going to get their act together for a while, and when they do they are at least reasonably accountable to the populous.

Perhaps if the geoengineering is part of a miltiary, farming or energy offering, but otherwise I doubt they will get long-term subsidy...

EDIT: add "in my opinion" to all of the above :)
