UK Energy and Clean Growth Minister Claire Perry has announced the United Kingdom's goal to lead an international challenge with Saudi Arabia and Mexico to remove carbon from emissions.

Very Large Scale Decarbonisation Partners (VLS Decarb) and Swansea University's Energy Safety and Research Institute (ESRI) are collaborating to develop carbon nanotube quantum conducting wire and capacitor technologies.

The capacitor technologies will provide a superior battery alternative to lithium ion battery technology and other chemical battery formats.

The conducting wire will afford huge savings in energy costs by virtue of drastically reducing energy losses in electric power transmissions lines and affording the storage of intermittently produced electric power from renewables such as wind, wave and sun.

These innovations will assist hugely in controlling atmospheric Carbon Dioxide (CO2) to within the levels stipulated by the Paris Climate Change Accord of December 2015.

Specifically, quantum conducting wire and capacitors could obviate enormous volumes of CO2 generated in the production of electric power; volumes sufficient to potentially arrest the progression of climate change and achieve the goal of reversing the harmful effects being experienced from unmitigated CO2 emissions of human origins.

The VLS Decarb Research and Development Consortium – The group's patent pending suite of technologies is being advanced by an extensive R&D collaboration involving VLS Decarb's academic and industry partners, which includes, in addition to the Energy Safety Research Institute at Swansea University, an international array of academic and governmental institutions and funding agencies.

This research and development effort is funded in part by the Welsh Government Sêr Cymru Chair Programme and the Sêr Cymru National Research Network in Advanced Engineering and Materials (NRN-150) in partnership with VLS Decarb.

The group's patented and patent pending suite of technologies enable the development and deployment of "Armchair" Quantum Conducting Wire (AQW) and "Armchair" Quantum Capacitors (AQC).

AQW and AQC are composed of single wall carbon nanotubes (SWCNTs) of correct "chirality" (molecular geometry), diameter, and length (perceived as resembling "armchairs" in their molecular appearance) and have been shown to possess quantum conductance. Therefore, they are sometimes referred to as "metallic" carbon nanotubes. Typically, SWCNTs are about one nanometer in diameter, which is about 1/100,000th the diameter of a human hair.

Benefits of the carbon nanotube quantum capacitors could provide a superior alternative to lithium ion batteries in terms of performance aspects such as:

  • Conductivity 6.3 times greater
  • Near zero thermal expansion – passes more current without thermal burden
  • Dramatically reduced size for equal energy storage
  • Much lighter (30%) weight for equal energy storage
  • Very rapid charging times
  • Essentially infinite operational life
