The objective of the study was to identify, on the basis of existing technology, the most economical solutions for transport, handling and storage of bioenergy fuels serving major combined heat and power stations. The main focus of the study was on transport systems for short rotation forests. The most competitive option today involves chipping in the stand and transport of the willow (Salix) chips in container trucks. The most efficient method of harvesting willow shoots is to pile the shoots at the edge of the site, to comminute them by means of a chip harvester and to transport them in container trucks. To minimize energy losses during storage, the piles of tree residuals and willow shoots should be covered, with storage taking place as close to the site as possible and with comminution carried out at the point where the chips are loaded for haulage by road. For maximum utilization of the machines and, hence, to minimize costs, a steady flow of biomass should be maintained. An alternative solution for private woodlot owners operating independently is to harvest shoots using a farm tractor, to use a tractor-drawn unit for chipping, and to restrict haulage of shoots and chips to short distances.
