1. Theme description
Since 1970, the science had tried to find a solution at the energy crisis, developing new method to use and storage renewable energy.
The United States Department of Energy has expected that the world’s energy consumption will be increased by 20% and that overuse fossil fuels will have a hard impact on climate.
The hardest current global challenge is to use the renewable energy rather than fossil fuels, improving the storage energy efficiency.
One of the most interesting technologies in the energy storage and conversion is the nanostructured materials for their mechanical and electrical properties.
Carbon nanotubes (CNTs) are a kind of nanostructured material with very good electrical and mechanical properties thanks to their dimension and surface properties. Carbon nanotubes were discovered in 1991 as a minor byproduct of fullerene synthesis. The research into CNTs has increased, reducing significantly the cost of this technology and improving the processability and scalability. Nanotubes discovered are of two types: single-wall and multiwall.
In the following, an overview the thermal processes to store energy, in particular the using of Carbon nanotubes in energy field (with a description of this technology and a presentation of the major results obtained by CNTs) are reported.
