Abstract

The utilisation of biomass poses large challenges in renewable energy systems and buildings account for a substantial part of the energy supply also in 100% renewable energy systems. The analyses of heating technologies show that district heating systems are especially important in limiting the dependence on biomass resources and to create cost effective systems. District heating
systems are especially important in renewable energy systems with large amounts of fluctuating renewable energy sources as it enables fuel efficient and lower cost energy systems with thermal heat storages. And also district heating enables the use of combined heat and power production (CPH) and other renewable resources than biomass such as large-scale solar thermal, large-heat
pumps, geothermal heat, industrial surplus heat etc. which is important for reducing the biomass consumption. Where the energy density in the building stock is not high enough for districts heating geothermal heat pumps can be recommended for individual heating systems, although the costs and biomass consumption is higher than the district heating solutions.
