Second Generation

In addition, several types of biofuels are currently under development that could become available in the mid or long term. Most of these technolo­gies use lignocellulosic biomass (“second generation”) in the form of wood residues, paper waste, agricultural waste, and dedicated energy crops. Feed­stocks of this type are far larger and are expected to be more “sustainable,” because of higher yields, lower net greenhouse gas emissions, and a lack of competition with food production.

Currently, creating biofuels from algae (hydro-cultures that could pro­vide high yields of oil) is gaining interest. Test flights of planes with biofuels (in at least one case originating from algae) have been performed.
