The objective of the presentation is to promote FBC Technologies in the Caucasus region countries, in order to (a) meet their energy needs, and (b) achieve environmental standards conformation. Penetration possibilities of Fluidised Bed Combustion technologies in the Caucasus region countries seem to be significant due to aged and low efficiency units. The total installed capacity of thermal power plants in the Caucasus region is about 8.1 GW. However, less than 70% of total capacity is operational at present. Operating thermal power plants consist of aged and low efficiency poor environmentally performing units, suffering from lack of maintenance and often experiencing fuel shortage. Moreover, heat demand cannot be covered at present in any country. Exploitable solid fuel reserves consist of coal, mainly located in underground deposits in Georgia, and biomass. Caucasus coal exhibits low heating value and high ash content. It is considered that such poor quality fuel can be best exploited as burning fuel. Potential biomass utilisation is significant in all three countries (Georgia, Armenia and Azerbaijan), especially by wood, wood wastes and municipal wastes exploitation. Adoption of FBC technologies constitutes an economically attractive solution that will promote the utilisation of domestic marginal and not fully exploited fuels, such as coal and biomass, by employing more efficient and environmentally friendly combustion technology. FBC technologies have to compete price and availability of other fuels (i.e. natural gas) and to overcome barriers such as the lack of large-scale projects in Caucasus countries, the state-own monopoly of the power sector, and any opposition to coal-fired technologies. Moreover, substantial funding should be attained in order to compensate for the present limited investments. Future energy market liberalisation and harmonisation with EU legislation will further enhance the penetration possibilities.
