Activities of Poland in Oxy Combustion

  1. 1. National Centre for Research and Development Strategic Programme „Advanced Technologies for Energy Generation” ACIVITIES OF POLAND INCFB OXY-FUEL COMBUSTION Wojciech Nowak Piotr Grzybowski Czestochowa University of Technology, Poland Jozef Pacyna, NILU Norway POLEKO 2012
  2. 2. The European Commission is calling for increased ambition in EU climate legislation. Brussels to argue for 25% CO2 reduction target in 2020, at least 80 percent in 2050 from 1990 level World primary energy demand over the 20 years will increase by approx. 30%. Poland plans to meet the 2020 EU emission targets by introducing atomic energy in almost equal measure with renewables as well as Carbon Capture and Storage (CCS) Poland relies on carbon-intensive coal for more than 90 percent of its electricity Poland blocked an EU declaration on climate policies and has repeatedly said it would oppose any more stringent climate policies than those already agreed2 Projekt Strategiczny - Zadanie badawcze nr 2 prof. dr hab. inż. Wojciech Nowak
  3. 3. CCS applied to a modern conventional power plant could reduce CO 2 emissions to the atmosphere by approximately 80-90% compared to a plant without CCS3 Projekt Strategiczny - Zadanie badawcze nr 2 prof. dr hab. inż. Wojciech Nowak
