Generations of Biofuel

In recent years, biofuel has gained popularity as a feasible substitute for conventional fuels like gasoline and diesel and as a renewable energy source. Depending on the complexity of their production procedures and the energy content of the fuel they create, the various types of biofuel are divided into generations. Fuels from the first generation include ethanol and biodiesel, which are produced by transforming organic material like sugarcane, corn, or soybeans into fuel. The second generation creates more sophisticated fuels like renewable diesel and drop-in aviation fuels that use cellulose and lignin as feedstocks to make a fuel that is comparable to those used in conventional transportation. The third generation is concentrated on utilising waste products to produce fuels, such as landfill gas and syngas, which are produced by transforming organic matter into a gas that may be used as fuel. Finally, the fourth generation is concentrated on the creation of advanced biofuels, such as hydrogen-based and algae biofuels. The current book chapter gives an overall idea about the various generations of biofuel and their source. The prospect for a larger-scale deployment of biofuel is becoming increasingly more enticing as the technology develops and the production costs become more affordable.
