Biofuels are emerging as integral and necessary research areas towards clean, next generation energy production, while providing alternative sources of sustainability. In addition to advancements in nanotechnology, many obstacles remain on the way for producing economically viable biofuels such as the challenges involved in the breakdown of cellulose, hemicelluloses, and lignin found in woody biomass. The use of micro-algae as a feedstock in biofuel has already been impacted by the advancements of nanotechnology. However, interdisciplinary breakthroughs are needed to make biofuels viable contenders as replacements for traditional fossil fuels. The authors discuss recent advances, benefits, and challenges facing nanotechnology in accordance with furthering our understanding and improving the state of biofuel manufacturing, including the implementation of nanotechnology in other aspects of biofuels production, such as cracking catalyst design, carbon nanotube electrodes for fuel cells, and enzymatic production of biofuels.

As global fossil reserves are abruptly diminishing, there is a great need for bioenergy. Renewable and sustainable bioenergy products such as biofuels could fulfill the global energy demand, while minimizing global warming. Next-generation biofuels produced by engineered microorganisms are economical and do not rely on edible resources. The ideal biofuels are alcohols and n-alkanes, as they mimic the molecules in fossil fuels and possess high energy densities. Alcohols and n-alkane hydrocarbons (C2 to C18) have been produced using engineered microorganisms. However, it is difficult to optimize the complex metabolic networks in engineered microorganisms to obtain these valuable bio-hydrocarbons in high yields. Metabolic engineering results in drastic and adverse cellular changes that minimize production yield in microbes. Here, we provide an overview of the progress in next-generation biofuel (alcohols and n-alkanes) production in various engineered microorganisms and discuss the latest tools for strain development that improve biofuel production.

Random extraction and consumption of fossil fuels have leads to a reduction in petroleum reserves. As for as developing countries like India is connected the need to search for alternative fuels is most urgent as India is heavily dependent upon the import of petroleum to meet its demands for automotive and power sectors. This has inspired curiously in alternative sources for petroleum based fuels. An alternative fuel must be economically competitive and environmentally acceptable. India has great potential for production of biofuels like Biodiesel from vegetable seeds. In the quest to find an alternative to the existing diesel and petrol fuels various Biodiesel and alcohol has been tried and tested in the Internal Compression engine. In this direction, an attempt has been made to investigate the performance and emission characteristic of Biodiesels and compare it with diesel. The Biodiesels considered are Tamanu, Mahua and Pongamia were tested with four stroke diesel engine. A drastic improvement in reduction of Hydrocarbon (HC) and Carbon monoxide (CO) were found for Biodiesels at high engine loads. Smoke and Nitrogen oxides (NOx) were slightly higher for Biodiesels. Biodiesels exposed similar combustion stages to diesel fuel. Therefore use of transesterified vegetable oils can be partially substituted for the diesel fuel at most operating conditions in term of the performance parameters and emissions without any engine modification.

Fossil fuels place a large strain on the environment due to the pollution produced through their extraction and usage. One method to reduce societal fossil fuel usage is through co-combustion of coal with woody biomass. However, overproduction of this biomass may lead to significant environmental deterioration. A potential sustainable substitute for the woody biomass is in the form of dried algae. Because the emission characteristics of algae combustion are unknown, a simple dry mass combustor was constructed, including necessary instrumentation, as part of an undergraduate design class with the goal of a more thorough characterization of algae’s combustion properties. The combustor is a simple and affordable design, in keeping with the classes’ principles of sustainability through a focus on energy, environment, and economy. The combustor consists of a flow controller that sends air into a metallic plenum, where modulations in flow are reduced before it is sent to a steel pipe for combustion. This paper describes the concepts involved in the design of this combustor, and preliminary assessment efforts employing the system when testing biomass pellets. Testing showed combustion efficiency greater than 98%, and the data clearly illustrates three separate phases to the reaction process, with rapid changes in emissions and temperature punctuating the ends of these phases.
