Biomass transport for energy: Cost, energy and CO2 performance of forest wood and manure transport chains in Switzerland

Biomass transport represents a significant share of the final price biomass for energy, and itself requires fuel, whose combustion adds to greenhouse gas emissions. We conducted techno-economic analysis main forest wood products in Switzerland (firewood woodchips), as well solid liquid manure. First, we identified most common chains from supplier consumer Switzerland, by conducting expert interviews that followed mental models approach. Then, quantified cost, energy environmental performance 12 these types biomass, using ratios. The results show is more performant than manure, except when underground pipes are used In case barrier cost rather or emissions performance. Energy required deliver consumers between 0.4% 1.8% primary contained wood, less 5% Some attain maximum break-even distances after 36 km only, whereas others could reach over 400 km.
