Carbon nanotubes for sustainable renewable energy applications

Carbon nanotubes (CNTs) are excellent candidates for renewable energy storage and conversion applications because of their extraordinary properties. These extraordinary properties are surface area, chemical, electrical, and mechanical properties. Because of these properties, its manufacturing is relatively simple. Several research articles have been published on the storage of hydrogen via CNTs, and their findings demonstrated that CNTs have outstanding hydrogen holding capacity. CNTs were the initial and most effective instance of nanoparticles, and they continue to have a significant role in creating sophisticated technologies for renewable energy applications. CNTs have been used in photovoltaic panels primarily for their enhanced electrical and thermal conductivity. Organic solar panels have a short lifespan because they degrade in the sun. Long-term, low-cost organic solar cell research is ongoing and will likely continue for the foreseeable future. In this chapter, the role of CNTs in the development of the conversion or storage of solar energy to electrical or thermal energy is extensively discussed. The storage capacity of the CNT-based materials has also been reviewed.
