Heating and cooling with biomass
Largest portion of final energy is used for heating of rooms and producing hot water or process heat for industry. The volume of biomass currently used for heat or cooling production was shown. The statistics of biomass heat is currently insufficient, so national experts participation is important. Combined with investigations where this biomass has been produced considerations about the reliability of the supply of biomass will be taken. The work concentrated on the domestic and district heating sector.
Furthermore, heating practices in different housing estates of different forms and sizes (heating in small and larger size e.g. public buildings) were described to investigate or estimate the most popular heating forms in Europe. As a result the most popular heating sources and techniques were defined. Also the current biomass cooling practices were studied and described.
The costs for heating and cooling with biomass were be surveyed in different countries based on the heat demand, specific heat consumption figures, technical level of installations, competition of other heating systems. On the one hand, as absolute figure and also relation to other used energy sources (e.g. heating oil, natural gas) were investigated. The CO2 savings potential was estimated in cases when fossil fuel based heating/cooling systems are switched to biomass based systems. The current policy instruments to encourage the use of biomass for heating and cooling on national and regional level were investigated.
