Bitumen, the viscous byproduct of oil sands extraction in Alberta, is traditionally used as fuel or to make asphalt pavement. But what if it could be transformed into a highly valuable, advanced material, such as the carbon fibers commonly used in aerospace, sports equipment and electric vehicles?
A team of Canadian researchers, led by Dr. Yasmine Abdin, have found a way to convert bitumen into commercial-grade carbon fibers. The solution uses a melt spinning technique to create two types of fibers in a cost-effective and environmentally friendly manner. The projected cost is estimated to be $12 per kilo, significantly lower than the current market price of $33 per kilo.
Their breakthrough was recognized in the first two phases of the Carbon Fiber Grand Challenge, a competition launched by Alberta Innovates to find new ways to extract value from the oil sands. The team plans to apply for the third phase of the challenge and start commercial production of their carbon fibers in 2024.
Driving towards a sustainable future
The potential uses for the newly created carbon fibers are vast, with electric vehicles (EVs) likely a major beneficiary. “Carbon-fiber bodies can compensate for the weight of the typical EV battery pack. Using carbon fibers in the chassis helps the battery stay cool, improving safety and extending the driving range,” explains Dr. Abdin.
Canada produces around two million cars and light vehicles annually, making local access to carbon fibers an appealing prospect for domestic automakers. By leveraging this breakthrough, they can gain a competitive edge while supporting Canada’s wider goals of reducing emissions.
