RELATIVE PROFITABILITY OF SHORT ROTATION CROP RESOURCES FOR BIOFUELS : IMPACTS OF BIOMASS YIELD AND TECHNOLOGY OF DENSIFICATION. SOFTWOOD RESIDUES AND MISCANTHUS APPLICATIONS.

摘要

Bioenergy using wood and non-wood cellulosic fibers as an alternative energy source is getting a huge amount of attention. The autor analyzes the economics and feasibility of harvesting, handling transporting and integrating wood and non-wood cellulosic fibers from operations in order to match the various components of the fuel supply chain. Focussed to biomass energy, a simple sensitivity analysis was carried out at the Aquitaine Region ( Southern of France) with increasing biomass yield of short rotation (miscanthus crops) compared with post harvest residues from the pinus maritimus forest. In the same geografical area, a complementary approach has been conducted in order to evaluate the impact of a new technology of compression which produces pellets or briquettes as a best raw biomass for combustion. The densification ratio and the moisture content of the biomass were the key factors to deliver the optimal price at the entrance of an industrial Combined Heat and Power plant (CHP).
