Algal Biomass: The algal biomass after oil extraction can be utilized for many useful products such as Biobutanol, Biogasoline and Methane. 

  Biobutanol:The green waste left over from the algae oil extraction can be used to produce butanol. using only a solar powered biorefinery. This fuel has an energy density 10% less than gasoline, and greater than that of either ethanol or methanol. In most gasoline engines, butanol can be used in place of gasoline with no modifications. In several tests, butanol consumption is similar to that of gasoline, and when blended with gasoline, provides better performance and corrosion resistance than that of ethanol

   Biogasoline: Biogasoline is gasoline produced from algal biomass like traditionally produced gasoline, it contains between 6 (hexane) and 12 (dodecane) carbon atoms per molecule and can be used in internal-combustion engines.

Methane: Algal biomass can also be fermented to produce methane or alcohol for energy generation. One kilogram of algae will produce sufficient methane to generate about one kilowatt hour of electricity. This provides a useful option to deal with surplus algal biomass and potentially post biogas production.
