Calgary researchers turn greenhouse gases into carbon fibre

Calgary researchers turn greenhouse gases into carbon fibre
A researcher at the University of Calgary says she has developed a method of turning greenhouse gases into valuable carbon nanofibres.
Mina Zarabian came up with the concept while completing her doctorate in chemical and petroleum engineering at the university’s Schulich School of Engineering.
The nanofibres have multiple industrial uses that included replacing metal in cars and airplanes, wind turbines, battery manufacturing and construction.
“This is a process that turns natural gas and CO2, carbon dioxide, both known as greenhouse gases, into solid carbon nanofibres which can be sold in a brick or powder for a lot of industries that utilize them,” Zarabian said during a tour of her lab.
Lines from tanks of carbon dioxide and methane feed into a small chamber the size of a balloon.
Once it’s exposed to extreme heat, black powdery residue appears in a glass tube. A piece of metal in the tube acts as a catalyst.
“It’s the secret sauce of our process,” said Zarabian.
“The good thing is it’s not something very magical or expensive or platinum or some super-fancy expensive metal. It’s a normal metal which can be found anywhere with a high amount of resources.”
Carbon fibres are expensive and currently cost about $100 per kilogram, she said.
Zarabian would like to see the technology eventually installed at natural gas power plants

Liquid light, making various chemicals from co2.

Liquid Light is a New Jersey-based company that develops and licenses electrochemical process technology to make chemicals from carbon dioxide (CO2).[1][2] The company has more than 100 patents and patent applications for the technology that can produce multiple chemicals such as ethylene glycol, propylene, isopropanol, methyl-methacrylate and acetic acid. Funding has been provided by VantagePoint Capital Partners, BP Ventures, Chrysalix Energy Venture Capital, Osage University Partners and Sustainable Conversion Ventures.[3][4] Liquid Light’s technology can be used to produce more than 60 chemicals, but its first targeted process is for the production of monoethylene glycol(MEG) which has a $27 billion annual market.[2] MEG is used to make a wide range of consumer products including plastic bottles, antifreeze and polyester fiber
