VTT wins innovation prize for a new bio-oil production technique
The use of bio-oil has significant positive effects on the environment.
By replacing fossil fuels with bio-oil in heat generation, carbon
dioxide emissions can be cut by 70–90 per cent. Sulphur emissions are
also considerably lower.Bio-oil has for a long time been pegged as the successor of fossil
fuels as our future source of energy. However, large-scale commercial
use of bio-oil in heat generation requires a cost-effective production
technique. The new technique enables a considerable cut in the
production cost of bio-oil.
Fast pyrolysis involves heating biomass such as forest industry waste
to a high temperature to form gas. When the gas is cooled, it condenses
into liquid known as bio-oil. Combining the pyrolysis process with
traditional fluidised bed boilers used in power plants brings a range
of efficiency gains. Producing bio-oil with the new technique is
cheaper than in a separate pyrolysis process. Bio-oil plants that are
integrated into power plants are extremely energy-efficient, because
the energy contained in the by-products of the pyrolysis process can be recovered in fluidised bed boilers. The innovation award for the new technology was distributed in December by the European Association for
Research and Technology Organisations EARTO. EARTO wants to reward
innovations that have significant societal and economic impact.
