Bio-oil to replace fossil fuels

Fortum Otso bio-oil is produced from wood-based raw materials like forest residues, wood chips or sawdust. Bio-oil is produced using fast pyrolysis technology.

​Bio-oil replace heavy or light fuel oil e.g. at heat plants and in industrial steam production. In the future, bio-oil can be used as a raw material for various biochemicals or traffic fuels.

Fortum Otso bio-oil is competitively priced and ideal for sites with logistics that are designed for liquid fuel. Fortum Otso bio-oil is virtually sulphur-free, and it is a cost-efficient alternative for meeting energy production emissions limits.

Produced in Joensuu, Finland

A bio-oil plant integrated with Fortum’s combined heat and power (CHP) plant in Joensuu, Finland, was commissioned in autumn 2013. The bio-oil plant utilises fast pyrolysis technology and is the first of its kind in the world on an industrial scale.

Sustainably produced 

The sustainability system Fortum uses is approved by Finland’s Energy Market Authority and indicates that Fortum Otso bio-oil is produced from environmentally sustainable wood-based raw materials. Every quarter, customers who purchase the bio-oil receive a sustainability declaration with key information about the sustainability of the amount purchased.

Bio-oil properties

Even though bio-oil can be used as a replacement for light and heavy fuel oil, it is completely different from fossil fuels in terms of composition and properties.

Bio-oil is ideal for use in applications where the steam or thermal loads fluctuate. Load adjustability with bio-oil is similar to that of fossil fuels.

Bio-oil is acidic, so all materials in contact with must be compatible with bio-oil. Suitable materials include acid-proof and stainless steels and most plastics. Our experts can advise customers on converting equipment for bio-oil use.

Innovation award

The Global District Energy Climate Awards organisation presented Fortum with an innovation award in autumn 2013 for the investment project in which the bio-oil plant based on fast pyrolysis technology is integrated with existing combined heat and power production and an urban district heating network.
