Plant will use oil sands CO2 emissions to turn algae into fuel, fertilizer and livestock feed.

CALGARY – The federal government, an oil giant and a biofuels company are teaming up to build a $19-million plant in northern Alberta that will use carbon dioxide emissions from the oilsands to help turn algae into products such as fuel, fertilizer and livestock feed.
It’s the first project to receive funding under a restructured National Research Council, which earlier this week announced it would focus on technologies that can help businesses, rather than on more general scientific endeavours.
Ottawa is pitching in $9.5 million to build the plant at Canadian Natural Resources Ltd.’s Primrose South oilsands project near Bonnyville, Alta.
Canadian Natural, one of Canada’s biggest energy companies, will contribute $6.3 million and Toronto-based Pond Biofuels will shoulder the remainder.
Pond’s technology essentially feeds carbon dioxide emissions from smoke stacks – whether it’s at an oilsands site, coal plant or factory – to algae.
Waste heat and water from Canadian Natural’s operations will also be used to help the algae grow.
As it blossoms, the algae develops fat – in other words, oil, said Joy Romero, vice-president of technology development at Canadian Natural.
That oil can be blended with heavy bitumen to make it flow more easily through pipelines, or sold to refiners, who can turn it into diesel or gasoline. The company says the oil is of the same, if not better, quality as West Texas Intermediate, the key US light oil benchmark.
The material left behind once the oil has been stripped out can be used as a fertilizer, which Canadian Natural needs as it looks to return used up oilsands mines to their natural state.
John Parr, Canadian Natural’s vice-president of thermal projects, added that the biomass is high in protein and carbohydrates, making it a “perfect” animal feed.
“Certainly Alberta is cattle country, so there would be a great market there for it I think as well.”
The algae technology could reduce emissions by 15% at Canadian Natural’s massive 110,000-barrel-per-day Horizon oilsands mine north of Fort McMurray and by 30% at its steam-driven Primrose operations.
Canadian Natural president Steve Laut said the algae technology will be shared with the Canadian Oil Sands Innovation Alliance, a group of 12 oilsands companies that share environmentally friendly technologies without intellectual property concerns getting in the way.
He said pursuing such a project would be “very difficult” without government support.
“To say this would have happened without them is naive,” he said. “We needed the NRC to get that base technology to where we are today. Pond Biofuels brings an important part of it and we’re here to make the commercialization and the implementation of it go.”
