Fortum and Metso in R&D co-operation around oxyfuel combustion technology
Fortum and Metso have joined forces in exploring oxyfuel combustion technology.
Oxyfuel combustion is part of a technical concept which enables carbon capture
in power and heat generation. The three-year R&D project is partly funded by
Tekes, the Finnish Funding Agency for Technology and Innovation.
The goal of the development activity is to determine how oxyfuel combustion
technology could be implemented in an industrial-sized power plant using
circulating fluidized bed technology. A key feature of such boilers is that they
can be operated on a wide selection of fuels, like coal and biomass separately
or together as any mixture.
“Comprehensive testing will be carried out during 2010, and the results can be
utilized both for modernization purposes and for the design of new power plants
to create preconditions for the CO2 capture in the future. Oxyfuel combustion at
power plants using circulating fluidized bed technology is a promising method
for reducing CO2 emissions. During the research, Metso's 4-MW test plant in
Tampere, Finland will be modified for oxyfuel combustion,” states Kari
Kuukkanen, General Manager, Technology at Metso.
In the oxyfuel combustion process fuel is combusted with pure oxygen diluted
with recirculated flue gas instead of air. In such case, after the cleaning the
flue gas would consist mainly of CO2 and water vapor. After removal of the water
vapor, CO2-gas is ready to be pressurized at the power plant, transported and
"Fortum's long term goal is to be a CO2-free energy company and we have been
working towards this goal systematically for several years. This project is an
important part of Fortum's long-term R&D activities because the technology can
be applied not only in coal-fired energy production but also in power plants
using biomass as fuel. Applying CCS to biomass-fired plants would create a
carbon sink", says Marja Englund, manager of the project at Fortum.
The experimental research effort focuses on oxyfuel combustion but is a
significant step in the development of carbon capture and storage (CCS)
technologies. Carbon capture and storage is shown to be one of the key
technologies for CO2 emissions reduction in energy production in numerous
scenario analyses. In addition to moving towards emission-free energy
production, improved energy efficiency is essential in order to reach emission
