Fortum utilises both solid biomass and liquid biofuels in CHP production and in heat-only production. These fuels include e.g. forest chips and other wood-derived fuels and vegetable and animal oils and fats. In addition, part of the municipal and industrial waste burned is bio-based.
In 2013, Fortum used a total of 6.8 terawatt-hours (TWh) of biomass and biofuels, accounting for about 5% of our primary energy use. The amount increased by 11% from 2012.
Solid biomass and liquid biofuels are used in Fortum's CHP production and in heat-only boilers in Sweden, Finland, Poland and the Baltic countries. During the year four new CHP plants utilising biomass and waste, were inaugurated in Klaipeda (Lithuania), Jelgava (Latvia), Järvenpää (Finland) and Brista (Sweden).
Additionally, the production of bio-oil based on pyrolysis technology started in November at the Joensuu CHP plant in Finland.
Construction of a 410 MW bio-CHP plant started at Värtan, Stockholm, in January 2013. The plant is expected to be in
operation in 2016 and will be one of the world's largest bio-fuelled CHP plants.
Fortum's plant to be commissioned in 2016 in Stockholm will be one of the largest bio-fuelled CHP plants in the world.
Increasing the use of bioenergy was researched at many power plants. At the Värtan power plant in Sweden, testing the use of olive stones in the fuel mix continued. Altogether 12,200 tonnes were burned and their share in the fuel used was 2%. At the Czestochowa CHP plant in Poland, the share of biomass, both forest and agricultural, in fuel use was one third during 2013.
Fortum is also a leading user of municipal waste in the Nordic and Baltic countries. The use of waste fuel amounted to 2.8 TWh (2012: 2.3). Utilising municipal waste is an essential part of sustainable waste management because it can reduce the amount of waste that would otherwise end up in landfills. It is also environmentally benign since the energy content of the waste can be utilised thus reducing the need for other energy sources.
The sustainability, especially the carbon neutrality and renewal, of biomass is subject to intense debate in the EU. Fortum participated in the discussion on this topic and has established its position and actions to ensure sustainable use of bioenergy in its operations. Fortum is a member in several international networks and organisations promoting the sustainable sourcing and use of bioenergy.
