Abstract:
The district heating is the most common heating system in space heating in Finland, with the share of 45%. The heat is mainly produced with combustion technology (the share of 86%) and the main fuels are biomass: 52%, peat: 12%, natural gas: 14%, oil: 3%, and coal: 15%.The aim of paper is to analyse what could be the alternative non-combustion technologies in district heating in future and what is the role of biomass in these circumstances. Background of this topic is EU and national level conversations about sustainability of biomass fuels and there is also willingness to replace existing combustion technologies in district heating. The possibilities of future technologies are compared to existing CFB boiler which is located in city of Mikkeli and region of SouthSavo. In this study, the alternative district heat production technologies are geothermal heat, secondary heat sources and heat pumps, electric boilers, and hydrogen technology. The results based on ongoing research project and the use of small modular reactors will be studied later.The district heat network is expensive part of system and it make sense to utilise although the source of heat will be replaced. In the future larger variety of new production technologies will be utilised and particularly local secondary heat sources will be utilised more effective. Currently many new technologies are in planning process, but it can take time when investments will be realised. Hence the forest biomass will be part of production mix in future. The utilisation of CO2 could be boosts the use of biomass.
