The COMBO-CFB project, led by VTT Technical Research Centre of Finland, has innovated a concept to increase solar energy production in the energy system.

According to the research, the new concept can reduce fuel consumption and emissions stressing the climate by more than a third.

The concept is based on the combination of concentrated solar power (CSP) technology and a traditional power plant process into a hybrid plant, which produces electricity on the basis of consumption. If part of the fuel consumed by a power plant is replaced with solar energy, power plant emissions will be reduced.

The project examined how various types of hybrid plant solutions can produce power flexibly according to demand, without the need for energy storage.

The implementation of the CSP technology in power production is suitable for areas with an abundance of sunlight, such as countries bordering the Mediterranean. However, this technology can also be implemented in areas with less sunlight by using hybrid power plants in which solar power is supported by another form of energy.

VTT conducted the research in collaboration with the University of Oulu, Amec Foster Wheeler, Vaisala, Telog, Pöyry, Finnish Energy and the Federation of Finnish Technology Industries.
