Carbon nanotubes capture CO2

Nanotech provides a solution to yet another vexing problem.

From the link:

Membranes made with carbon nanotubes could reduce the amount of energy needed to capture carbon-dioxide emissions from smokestacks, and therefore cut costs, according to a company that will receive $1 million from the new advanced-research projects agency for energy, Arpa-e, to develop the technology.

The company, Hayward, CA-based Porifera, claims that its carbon-nanotube membranes could capture one billion to three billion tons of carbon dioxide a year and save $10 billion a year compared to existing CO2 capture technology. At this point, however, the work is at an early stage, says Olgica Bakajin, Porifera’s chief technology officer. She expects that it will be another year before the first prototype is ready.
