|WP3.||Promotion of CCT Implementation Options in Existing Coal-Fired Power Plants|
In the framework of this work-package promotion of Clean Coal Technologies (CCT) is attempted in East European countries, Russia, South Caucasus countries, the Balkans, India and China. Activities included collection of analytical information for each country, evaluation of the existing situation and identification of the retrofitting options that can be applied. Data collection included structural, legislative and technological aspects of existing power plants, fuels used for electricity generation, further needs and planned development, while it helped creating an inventory of the current situation in assessed countries. Specifically for the Russian power sector, scenarios for retrofitting options, according to specific analysis criteria, have been developed and are presented. In general, a good picture of the power sector in each country has been recorded, and an inventory of the current situation in assessed countries was created.
Moreover, developments in Clean Coal Technologies (CCT) and possible implementations through European know-how transfer have been presented in regional workshops and international conferences, while CCT promotion also included articles submission in scientific journal, distribution of newsletters, meeting discussions, site visits at TPPs and dissemination of work-package results through partner and CFF OPET web sites.

Objective and Strategic Aspects
· Enhancing security of supply in partner countries by means of domestic fuel utilisation and diversification (including poor quality fuels)
· Preservation and development of mining and utilisation of local fossil fuels, resulting in improved employment prospects in related sectors and reduction of imported fuel cost
· Promotion of European technologies in new promising markets
Contribution to EU Policies
· Clean Coal Technologies constitute a European developed option for retrofitting the solid-fuel power sector. Their promotion is in accordance with EU support of sustainable development, since CCT implementations result in fuel flexibility and availability, reduced operating and maintenance costs, while environmental standards and compliance with international agreements can be met
· Promotion of CCT is also in accordance with EU policies of supporting the rehabilitation of local industries, the enhancement of renewable energy sources exploitation and the establishment of a contemporary legislative framework
Scientific/Technical Objectives and Innovation
· Promotion of advanced European technology to promising markets, which may lead to increased efficiency and improved environmental performance in power generation
· Utilisation of domestic fuels, including poor quality and problematic ones
Results - Deliverables
Solid Fuel Power Sector of India, China, East European, South Caucasus and Balkan Countries
Current Situation – CCT Implementation Possibilities
All partners involved
The report consists of 13 parts analytically describing the coal-fired power sector of each country. In each part there are sections describing the electricity generation status, the coal-fired power plant park, the ownership and technical status, fuels used for electricity generation and future trends. Especially for Russia, there is a section illustrating the potential introduction of CCTs through renovation activities.
The countries that are under investigation are Russia, Bulgaria, Serbia and Montenegro, Romania, FYR of Macedonia, Estonia, Lithuania, Latvia, Poland, Georgia, Azerbaijan, India and China.
In terms of coal reserves the above mentioned countries own more than one third of the world total coal reserves (BP statistical review 2003) with Russia, India and China owning 15.9%, 8.6% and 11.6%, respectively. As far as electricity production is concerned the countries that are under investigation produce more than 21% of the world-produced energy.
Future trends in electricity generation in each country reveal that coal and lignite will continue to play key role in power production. Country reports are focused on effiency and environmental performance of coal-fired units, problems encountered during their operation and possible options for rehabilitation projects. CCT implementation possibilities are quite promising due to poor efficiency, high emissions and age of too many operating units. Experience of retrofitting old units with new ones of advanced technology is presented, as well as plans to implement any CCT technologies in each country. Support in implementing modern technologies by large-scale or research projects is described and their financing opportunities. The need to compete price and availability of other fuels, such as natural gas, is illustated in growing markets.
Reserves of other than coal solid fuels, such as oil shale, peat and biomass, and their potential exploitation are presented in countries with insignificant coal reserves. CCT implementations for such fuel are also considered. Joint projects for power production from solid fuels are investigated as well.

List of Participants
Representatives from construction companies, industries, governmental experts as well as energy specialists from Research Centres and Universities, mostly from Balkan countries (Romania, Bulgaria, Yugoslavia and FYROM), rest of Europe (Finland, Austria), and Canada, participated in the Symposium, which facilitated the contact between them, in order to establish strong partnerships for large energy projects. Total number of participants: 59. Special attention must be given to the participation of representatives from Foster Wheeler Energia Oy (Fi), Can Met CETC/NR (Ca), AE&E (Au), RAFAKO SA (Pl) and PPC (Gr).
The aim of the Workpackage is to promote Clean Fossil Fuels Technologies through alternative renovation options, applicable to existing power plants with operational problems in the candidate and new promising countries, in order to ensure a cleaner and more efficient operation. Following this line, the main scope of the Symposium was the promotion of FBC technology to energy policy makers and coal users, through the presentation of the benefits, the environmental friendly and high efficient performance of the specific “clean coal” technology.
Technological Results – Conclusions
During the Symposium, the advantages of FBC technology were properly stressed out. FBC is a mature technology, tested and implemented widely in EU countries. The specific technology was agreed to be the most proper technology to be used in the Balkan countries, due to the poor coal quality and the large potential of co-combustion with wastes and biomass.
Representatives from large manufacturers EU companies had the chance to meet with representatives of power plants, energy specialists and governmental experts and develop a personal contact with them. The given situation in each country was presented, and the already implemented technology was presented, along with some success cases. This fact will facilitate the implementation of FBC technology to the Balkan countries, with the respective environmental benefits.
