Nanofibers are already used in the construction of everything from automotive to aerospace manufacturing. Previous nanofiber manufacturing methods have been time-consuming and considerably more expensive. But, as Technology Review states,
"It’s more than just a simpler, less expensive way of making a high-value product. It’s also a “means of storing and sequestering carbon dioxide in a useful manner, a stable manner, and in a compact manner,” says Licht. He points out that if the process is powered by renewable energy, the result is a net removal of carbon dioxide from the atmosphere. In a recent demonstration, his group used a unique concentrated solar power system, which makes use of infrared sunlight as well as visible light to generate the large amounts of heat needed to run the desired reaction."
Massive implementation of the process will likely require a major shift in manufacturing infrastructure. But, as the tech improves, this just might be a possibility.
Here's a video from Discovery about the process and it's implications:
