Fossil fuels - sources of CO2 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.

COCO22 reducing options 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.

• this documentation is handed to Energy Regulatory Officewhen 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,

Co-firing avoided emission - case study Co-firing avoided emission - case study for Polandfor Poland

Declared amount of “green electricity” for selected Polish power producers )* :

Eren= 860 000 MWh

Such electricity production in a condensing power plant with 37% efficiency needs chemical energy equivalent

to:

Ech= 8 360 TJ

This gives an avoided emission of CO2: (subbituminous coal; WE=96 tCO2/TJ, WU=0,98)

EmAV=787 000 tCO2/a)* basing on calculations included in individual certification documentation.

Equivalent to ca. 8 mln USD next year

ConclusionsConclusions

• 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,
