1 AVOIDED CO 2 EMISSION IN CO-FIRING Marek Sciazko Ph.D. Institute for Chemical Processing of Coal (IChPW) 1 Zamkowa Str., Zabrze, Poland tel.: + 48 (32) , fax.: + 48 (32)

2 PYROLYSIS, GASIFICATION AND COMBUSTION OF BIOMASS AND WASTES EXELLENCE CENTRE EXELLENCE CENTRE CONBIOT accredited laboratory pilot tests industrial tests technical co-operation audits and designing feasibility studies Partners: 17 R&D Centres

3 Fossil fuels - sources of CO2 The overall efficiency of a power plant is significantly reduced if CO2 is captured from flue gas. Fossil fuel - still the most important energy source with almost no other alternative. It is the major source for greenhouse gases that are assumed to cause global warming.

4 CO 2 reducing options Decreasing of carbon loaded fuel consumption by increasing the conversion efficiency Switching to lower carbon content fuels e.g. natural gas instead of coal. Replacing coal with neutral CO2 emissions sources, such as renewable energy derived from biomass.

5 Current legal status of co-firing in Poland Ordinance Concerning the Detailed Scope of Obligatory Purchase of Renewable Energy and Electricity Produced in Co-generation 30th May, 2003 Ministry of Economy and Labour Ordinance Concerning the Detailed Scope of Obligatory Purchase of Renewable Energy ? (expected time: 1st January 2005) (draft) Ministry of Economy and Labour CONBIOT Center was consulting this Ordinance !

6 Whats new in the new Ordinance? this documentation is handed to Energy Regulatory Office when applying for green energy (electricity or heat) selling possibility, Avoided CO2 emission procedures the requirement of preparing so-called certification documentation for biomass co-firing plants, detailed regulations concerning the analytical procedures for biomass properties (e.g. LHV, moisture content) evaluation, detailed regulations concerning biomass sampling procedures and measuring equipment,

7 ICPC/CONBIOT role in co-firing sector 12 completed certification documentations for Polish heat & power producers: Połaniec Power Plant - Electrabel Opole Power Plant Southern Energy Concern (Siersza, Laziska and Jaworzno) Stalowa Wola Power Plants Dolna Odra Group of Power Plants (Szczecin, Dolna Odra) Ostrołęka CHP Plant,... LABIOMEN - national network of supervised laboratories Institute developed own procedures for biomass and biomass/coal fuel blends - accredited in PCA

8 Co-firing avoided emission - case study for Poland Declared amount of green electricity for selected Polish power producers )* : E ren = MWh Such electricity production in a condensing power plant with 37% efficiency needs chemical energy equivalent to: Ech= TJ This gives an avoided emission of CO2: (subbituminous coal; W E =96 tCO2/TJ, W U =0,98) Em AV = tCO2/a )* basing on calculations included in individual certification documentation. Equivalent to ca. 8 mln USD next year

9 Conclusions biomass co-firing is an effective way of reducing CO2 emission, CO2 emission trade can be a way of obtaining an additional income for energy producers applying co-firing, reliable system enabling the calculation of green energy calculation and the calculation of C02 avoided emission requires a certified installation and procedures. unlike the methods of sequestration, it does not require significant R&D works and demonstration periods,

10 Co-operation proposal * Technical monitoring of co-firing impact on boiler performance * Procedures and measurements equipment for on- line moisture control in biomass U Certification procedures for co-firing U Analytical procedures for biomass, industrial and agriculture derived by-products
