Here's an interesting article about a pilot plant being made by CNRL and Pond Biofuels. Basically it appears they want to use CO2 produced in oilsands facilities to grow algae, which can then be used as animal feed, biofuel or fertilizer. The $19 million facility will be built at CNRL's Primrose South site near Bonnyville.
Clearly early days on this, but might turn out to be something important.
