Abstrakty

Wykorzystanie absorpcji chemicznej do wychwytywania CO2 ze spalin w eksploatowanych elektrowniach jest możliwe, podniosłoby jednak koszt produkowanej energii elektrycznej o 70%. Wykorzystanie zgazowania węgla do wychwytywania CO2jest możliwe jedynie poprzez całkowitą rekonstrukcję elektrowni (wymiana kotła i turbiny parowej na blok IGCC). Spalanie tlenowe stwarza możliwość sekwestracji CO2, która mogłaby być rozważana w odniesieniu do istniejących elektrowni węglowych. Warunkiem jest doprowadzenie tej technologii do gotowości wdrożeniowej. Wodór jako paliwo energetyczne jest znacznie droższy od paliw kopalnych.

EN

Utilisation of the chemical adsorption for removing of CO2 from the flue gas in power stations being under operation at present is possible, but it should cause the increase of costs of generated electricity by 70%. Utilisation of coal gasification for the chemical adsorption of CO2 is possible only by complete re-construction of the power station (replacement of the boiler and steam turbine by the IGCC unit). Aerobic combustion creates a possibility of CO2 sequestration, and it could be considered in the aspect of existing power stations. However, as a condition is here the implementation readiness of this technology. Hydrogen as a fuel for power engineering is more expensive than fossil fuels.
