Fortum Otso® bio-oil is fuel produced from wood-based raw materials, like forest residues, wood chips or sawdust. It can be used, for example, at heat plants to replace heavy or light fuel oil.
The use of bio-oil has significant positive environmental impacts, because the energy produced with bio-oil reduces greenhouse gas emissions by even more than 90% compared to fossil fuels.
Bio-oil produced in Finland has been used to replace heavy fuel oil at Fortum’s own heat plants. The 50,000-tonne capacity of the Joensuu bio-oil plant can meet the heating needs of over 10,000 single-family homes. In the future bio-oil produced at the power plants can also be used as a raw material for various chemicals or traffic fuels.
Fortum has also delivered its first export batch of bio-oil. It has been tested at E.ON’s Karlshamn power plant in Sweden. Based on the test combustion performed at the Karlshamn power plant, with the capacity of 1,000 MW, bio-oil can replace heavy fuel oil also in bigger power plants.
