Ultra-High Conductivity in Polymers
NanoCable – collaboration through NIST/ATP – Advanced Technology Program, US Department of Commerce
In September of 2007, NanoRidge, along with its industry partner The Boeing Company, was awarded a project grant from the highly-competitive NIST/ATP program. The project’s goal is to develop a lightweight, electrical wire-and-cable system that can reduce fuel costs and improve energy efficiency in numerous applications, including aerospace. The NanoCable project is a three-year funded effort designed to capitalize on the remarkable electrical properties of specific carbon nanotube types which conduct greater amounts of electric current than copper while having only one-sixth the weight. For more information on the NIST program and the NanoCable project, please see our press release on our Media and Press page.
Ultra-High Conductivity Umbilical – co-funded through RPSEA – Research Partnership to Secure Energy for America, US Department of Energy
NanoRidge is developing an electrical conductor suitable for use in subsea umbilicals that has conductivity greater than copper and allows for tieback distances approaching 100 miles. Carbon nanotechnology is a new technology that could enable power delivery to the seafloor where lightweight and high current is required.
Utilize carbon nanotubes imbedded in a polymer as a conductor. Individual nanotubes can have conductivities 100X that of copper.
