Summary Bio-oil in Joensuu View
Bio-oil production connected to existing DH and CHP, Joensuu, Finland
Bio-oil production in city of Joensuu is new type of trigeneration concept that is added to existing district heating and CHP. It is a great example of expansion of district energy business to new markets and areas beyond traditional district energy scheme. Bio-oil production create another way to utilize and capitalize local biomass that otherwise would be unused. It provides profitable business opportunity for local district energy company as well as reduces fossil supply, cut CO2 emissions and decrease imported fuel dependency. It also increases utilization of existing district energy system and CHP plant. PRF of district heating in Joensuu is equal to zero.
District heat production is dominated by CHP (94 %) that is primarily fuelled by local biomass and also by local peat. Share of local fuels in Joensuu district energy system is 95 % and it will be 100 % next year. Current renewable share is 65 %. Current CO2 emission factor (2012) is 103 g/kWh and current yearly CO2 reduction by DH is about 120 000 tons. Bio-oil will lower CO2 emission factor close to zero by cutting yearly greenhouse gas emissions about 60 000 tons. Overall yearly CO2 reduction by trigeneration and entire district energy system in Joensuu will be 180 000 tons. SO2 emissions will be reduced more than 300 tons by bio-oil.The productivity of DH and CHP is enhanced but bio-oil production has even larger positive impact on other local business like forestry and harvesting. Biomass chain for bio-oil production employs about 50 people.
Alternative for bio-oil would be imported fuels when money would go out of the area and country. District energy system with new type of trigeneration provides the best heating option for DH customers, profitable business for Fortum and a lot of jobs around the area as well as enables to keep fuel expenditures in own county.
Joensuu is a great example how district energy enables sustainable energy solution and generate welfare for entire area.Joensuu plant is the first industrial scale bio-oil production that is integrated to CHP in the world. However, this type of bio-oil production can be executed anywhere in the world. New trigeneration concept enables expansion of district energy to new sectors, markets and areas.
