Nanomaterial-based renewable energy solutions have improved the quality and yield of biofuels and bioenergy production. Bioenergy is a source of renewable energy and may be used to develop transportation fuels, heating, electricity, and other products. Due to the negative impacts of the overuse of fossil fuels on the ecosystem, bioenergy may play an important role as an alternative energy source. Biomass is the most common source of bioenergy. However, early steps for biomass conversion into biofuels, such as enzymatic hydrolysis, pre-processing, and biomass culturing can result in a variety of issues.

Nanomaterials have the potential to solve issues associated with the use of biomass sources for bioenergy conversion and storage. Nanotechnology can be used in a variety of industrial sectors to increase efficiency. Current research focuses on the development of new energy production sources that will be economically beneficial. Advanced nanomaterials have the potential to disrupt the whole energy economy and provide greater energy efficiency when applied to energy production processes. Regarding the use of nanoparticles for bioenergy and biofuel applications, nano-additives influence the anaerobic digestion process for biogas generation. Moreover, there are preliminary research findings on the use of nanomaterials as petroleum distillates, the in vivo toxicity of nanoparticles, and the molecular-scale mechanism of nanomaterial-protein interactions. The field of nanotech-based bioenergy requires additional research to determine the potential for bioenergy to replace fossil fuel-based energy in the future.
