Carbon Nanotubes Get Capacity Boost without Much in the Way of Demand Changing

Carbon nanotube producers seem to be in a rush to bump up capacity without any signs of what's causing the urgency

1 min read

You have to hand it to Bayer Material Science in their latest announced opening of the world’s largest carbon nanotube plant. Without any real indication that any or even one of carbon nanotubes’ (CNTs) applications are spiking in demand, they just added 200 metric tons to the world’s annual capacity.

Keep in mind Bayer’s pilot plant won’t be number one for long as France-based Nanocyl will be bringing on line a new reactor capable of 400 metric tons annually in July of this year.

In just 2007, Bayer made it known in an article in Chemical & Engineering News that its production capacity for CNTs was 60 metric tons. That means Bayer will be increasing its capacity by 300% in a little over two years to meet what they define as a 25% increase in demand. 

Along with Nanocyl’s production increase this year, it would seem there’s going to be a lot of carbon nanotubes flooding the market without much in the way of demand to use them. Maybe we will hear soon about the “killer app” for CNTs that is going to change that dynamic.

The State of the Transistor in 3 Charts

In 75 years, it’s become tiny, mighty, ubiquitous, and just plain weird

The most obvious change in transistor technology in the last 75 years has been just how many we can make. Reducing the size of the device has been a titanic effort and a fantastically successful one, as these charts show. But size isn’t the only feature engineers have been improving.
