The consortium led by Finland's VTT Technical Research Center has developed a new technology that more economically and ecologically captures CO2 emissions from power plants. The International Energy Agency IEA is indispensable for carbon dioxide capture if the greenhouse gas emission reduction goal is set to be met. This new technology combines traditional circulating fluidized bed combustion with oxygen-enriched combustion to make wider use of cheaper fuels and biomass energy.

To mitigate climate change and reduce greenhouse gas emissions is one of the biggest environmental challenges of today. According to the Intergovernmental Panel on Climate Change International Plant Protection Convention, carbon dioxide emissions should be reduced by 50-85% by 2050. Meeting this goal will mean that dozens of additional power plants will implement CO2 capture systems every year. Until now, capture technology has been in the experimental phase and the cost of implementing methods to mitigate it has been too high.
The Flexi Burn CFB project developed and successfully coordinated by the Finnish VTT Technical Research Center demonstrates the concept of oxygen-enriched combustion based on circulating fluidized bed combustion. This new technology combines CFB combustion based on oxy-combustion CO2 capture with flexibility and economic benefits. In addition, it is impossible for the same power plant to continue operating and capture, such as CO2 transportation and storage facilities during temporary outages, thereby reducing investment risks.
The advantages of circulating fluidized bed combustion include high efficiency, fuel flexibility, and the option to use a large proportion of biomass in the fuel. Raising energy prices and exhausting high-quality fuel reserves means that it is more profitable to use low-quality fuels. Fuel flexibility through this new technology will reduce the cost savings that are dependent on imported coal and create because cheaper options, including waste coal, can be used as fuel.
In Spain (a demonstration plant of 30 MWth), it is the world's largest technologically proven function of operating a circulating fluidized bed oxy-fuel plant. The project also developed a commercial-scale 300MWe plant concept. The technology developed in the project can capture the carbon dioxide generated by power plants, but its widespread commercialization will require political decisions and new legislation, particularly with respect to the storage and eventual disposal of carbon dioxide.
