Revisiting How Carbon Nanotubes Will Change Renewable Energy

100 times stronger than steel yet 4 times lighter. Conductive and biocompatible. Carbon nanotubes (CNT) are fascinating materials that could channel a kaleidoscope of futuristic technologies around sustainability. They could be a key to the zero-carbon energy future transition. While these graphene tiny tubes have been overhyped as revolutionary for about 30 years, they haven’t made it to the market yet. But we’re seeing slow progress towards interesting use cases, like a recent advancement that could turn carbon nanotubes into hot stuff for generating clean renewable electricity out of waste heat. Let’s revisit carbon nanotubes and see how things are shaping up.
