Economic Analysis of the Potential of Cellulosic Biomass Available in France from Agricultural Residue and Energy Crops

The objective of this research is to evaluate the feasibility and locations of using cellulosic biomass both from crop residues and from dedicated energy crops to supply 200-million-liter-biodiesel plants in France. The estimation of the potential amount of agricultural residue available in 2015 in each region of France is calculated. The residues considered in this study come from cereal straw and corn stover. Results show that eight out of the twenty one French regions have enough agricultural residues available to supply at least one 200 million liter biofuel plant. Region Centre has the largest potential, with enough residues to supply three to five plants. Finally, cost of supplying one biodiesel plant of 200 million liters in the region Centre is estimated. Results show that collection of biomass will be effective in an area with a radius of 58 Km to 168 Km depending of the raw material considered and its abundance. The cost of supplying a plant with miscanthus is much higher than with residues only. Thus, crop residues appear to offer a lower cost to produce biodiesel in the near term compared to a dedicated crop. Results show that production of biofuel from cellulosic biomass should not be limited by the supply of raw material, but costs of conversion to liquid fuels clearly will play a key role in the development of cellulosic biofuels. Energy prices and policies will have a significant impact on second generation biofuel development.

European Biofuel Policy: How Far Will Public Support Go?

The strong biofuel expansion experienced in the European Union (EU) originates in the incentives set up by Member States (MSs) within a global framework provided by the EU. A significant part of the EU rapeseed production (more than half) is now channeled into the energy market. MSs support the development of biofuels through subsidies/tax exemptions, mandatory blending, and import barriers (at least for ethanol). Several motivations for supporting biofuels have been put forward. For some MSs, the motivation was clearly to increase agricultural income (e.g., in France and Germany). In other cases, biofuels (produced domestically or imported) were mainly seen as a means to abate GHG emissions. Public support for biofuels has recently been questioned. Some potentially negative effects of biofuels (most notably the indirect land use change) have fueled the debates in the EU Parliament and Commission over the adoption of the 2008 Renewable Energy Directive. These discussions have led to the adoption of less stringent mandatory incorporation targets for 2020 (with respect to the initial 2007 proposal), as the objectives are now set in terms of “renewable fuels” (i.e., biofuels, hydrogen, and green electricity). In spite of an agreement on targets for 2020, some important questions still need to be addressed. The indirect land use change triggered off by biofuel production is the most critical. The ability of the Commission to come up with a clear methodology to address this issue is a necessary condition for the enforcement of the biofuel targets.
