The operation of a district heating system depends on the heat load demand, which varies throughout the year. In this paper, we analyze the coproduction of district heat and electricity or biomotor fuels. We demonstrate how three different taxation scenarios and two crude oil price levels...

Swedish energy strategies for transportation, space heating and pulp industries were evaluated with a focus on bioenergy use. The aims were to 1) study trade-offs between reductions in CO2 emission and oil use and between Swedish reductions and EU reductions, 2) compare the potential...

In this study, we compare and contrast the impact of recent technological developments in large biomass-fired and natural-gas-fired cogeneration and condensing plants in terms of CO2 mitigation costs and under the conditions of a competitive electricity market. The CO2 mitigation cost indicates...

Using energy systems analysis, we examine the potential to reduce CO2 emissions and oil use by integrating motor biofuel production with pulp mills. BLG-DME (black liquor gasification with di-methyl ether production) is compared with solid biomass gasification with BIG-FT (solid biomass...

The potential for energy conservation in space and water heating for five district-heated buildings of three types in south-west Sweden is analyzed. The energy savings for different conservation measures are estimated using a computer program which calculates daily building energy balances. The...

The impact of energy conservation between 1978 and 2010 on the utilization of existing and future district-heat production for a Swedish district-heating system are analyzed employing an end-use approach. The energy-conservation potential for space and water heating is calculated to be 35–40%...

Energy systems which significantly reduce emissions of acidifying gases and carbon dioxide from non-mobile sources are identified for Western Scania, using an end-use accounting model. Carbon dioxide emissions can be reduced to 75% and acidifying gases to 50% of 1988 levels by 2010 using an...

Regional production and utilization of biomass in Sweden is analysed, considering the potential of replacing fossil fuels and producing new electricity. Extensive utilization of biomass will decrease biomass-transportation distances. The average distance for biomass transportation to a...

Replacing fossil fuels with sustainably-produced biomass will reduce the net flow of CO2 to the atmosphere. We express the efficiency of this substitution in reduced emissions per unit of used land or biomass and in costs of the substitution per tonne of C. The substitution costs are calculated...
