Future production and utilisation of biomass in Sweden: potentials and CO2 mitigation

摘要: Swedish biomass production potential could be increased significantly if new methods, such as optimised fertilisation, were to used. Optimised fertilisation on 25% of forest land and the use stem wood almost double from forestry compared with no both logging residues large quantities excess not needed for industrial purposes used energy purposes. Together crops straw agriculture, total would about 230 TWh/yr or half current supply demand building same today. The methods are assumed cause any significant negative impact local environment. cost utilising produced has been analysed needs further investigation. Besides replacing fossil fuels and, thus, reducing CO2 emissions by 65%, this amount is enough produce electricity equivalent 20% power production. Biomass-based preferably through co-generation using district heating systems in densely populated regions, pulp industries regions. Alcohols transportation stand-alone less regions biomass. A high intensity reduce demands. There uncertainties regarding future purposes, arable available crop yields. These factors will influence earlier estimates vary 15 125 TWh/yr.
