  1. Perspectives of clean coal technologies in Poland Wojciech Suwala AGH-University of Science and Technology Faculty of Fuels and Energy

  2. Presentation plan • Basic facts on Polish energy system • Model of power generation • Power generation technologies 2002-2020 • Decomposition of CO2 emissions reduction • Conclusions

  3. Basic facts on Polish energy system • 70% of TPES from coal • 94% of electricity and heat generated form hard coal and lignite

  4. Basic facts on Polish energy system- challenges • LCP directive - derogations • EU accession treaty – country limits • ETS • 280 Mt CO2 required • 208 Mt CO2 assigned • Renewables obligation

  5. Model of power generation - 1 • Bottom-up model • Emissions constraints (SO2, NOx, PM) • Carbon tax to mitigate CO2 emissions • 100 coal grades • Variable demands

  6. Model of power generation -2 • Partial equilibrium • Objective function: consumers + producers surplus  MAX • Time horizon: 2002-2020 • Linear programming GAMS/CPLEX

  7. Model of power generationscenarios 1 SO2, NOx, PM emissions reduction as in EU Accession Treaty for the whole country (bubble)

  8. Model of power generationscenarios 2 Renewables obligation: 9% of electricity production from 2010 CO2 - carbon tax: 0 - 30 €/t

  9. Resultstechnologies mix, carbon tax 0 €/t CO2

  10. Results technologies mix, carbon tax 25 €/t CO2

  11. Results technologies mix, 2020

  12. Results technologies mix, 2020

  13. Technologies in 2020, carbon tax 25 €/t CO2

  14. Technologies in 2020, carbon tax 25 €/t CO2 Existing hard coal CHP public plants - life extension 47%

  15. Technologies in 2020, carbon tax 25 €/t CO2 New nuclear 15%

  16. Technologies in 2020, carbon tax 25 €/t CO2 9% 3% 8% 3% 3% 7% 5%

  17. Results CO2 emissions for carbon tax 0 – 30 €/t CO2

  18. Z=X1*X2 Δ Z(X1)= ΔX1*X20+1/2* ΔX1* ΔX2 Δ Z(X2)= ΔX2*X10+1/2* ΔX1* ΔX2 Decomposition principleShapley/Sun method X1 ΔX1 X10 ΔX2 X2 X20

  19. Decomposition identity

  20. Decomposition identity • process factor – related to: • physical / chemical properties of the technologies • fuel quality adjustment

  21. Decomposition identity fuel factor – related to emissions properties of fuels used

  22. Decomposition identity efficiency factor – related to amount of primary energy used to satisfy demand

  23. Decomposition identity demand factor

  24. Emissions decomposition effect = Δ factor

  25. CO2 emissions reduction – effects contributioncarbon tax 10 €/t CO2

  26. CO2 emissions reduction – effects contribution carbon tax 25 €/t CO2

  27. CO2 emissions reduction – effects contribution carbon tax 30 €/t CO2

  28. Conclusions 1/2 • Coal technologies should have still a large share in energy supply for Poland • Traditional coal technologies need to be replaced by clean coal technologies • Increase of demand could be balanced by renewable and nuclear energy

  29. Conclusions 2/2 • Major factors which in longer term contribute to CO2 emissions reduction are fuels switch and efficiency increase, the latter enhances the role of clean coal technologies • Demand decreases contribute to emissions reduction basically in short term

  30. Thank you for your attention
