Canadian government funds eight carbon-capture technology projects

You are at: Oilgae Blog.

The federal government has put up $140 million for eight projects aimed at refining and proving carbon capture and storage technology.

The Great Plains Synfuels plant in North Dakota pipes its CO2 to the Estevan oilfield, where it is injected into the ground to create pressure that will allow the extraction of more oil.

Ken Caldeira, a climate scientist with the Carnegie Institution in Stanford, Calif., said - the problem with this technology is that liquefying coal, then burning the synthetic oil that results, emits 25 to 50 per cent more CO2 per energy unit than petroleum does.

Scientists have known for a while now that some strains of algae can be converted to biodiesel fuel, but the process was slow and expensive.

Now they’ve found that a particular metal oxide can be the catalyst for quicker, cheaper conversion of the algae.
