Components for the calculation of the OCvar for Combustion (1) • Electricity coste * ce * 103 [k€/PJ fuel input/a] • e : additional electricity demand (=new total consumption – old total consumption) [GWh/PJ fuel input] • ce : energy price [€/kWh] • Sorbent cost s * cs * efunabated * / 103 [k€/PJ fuel input/a] • efunabated : unabated emission factor of pollutant [t pollutant/PJ fuel input] • s : specific sorbents demand (e.g. NH3) [ton/t pollutant removed] • cs : sorbents price [€/ton] • : removal efficiency (= 1 - efabated/efunabated) • Catalyst cost (cat * cicat / ltcat) * (103 / 3,6) [k€/PJ fuel input/a] • cat : catalyst volume (per unit of installed capacity) [m3/MWth] • cicat : unit costs of catalysts [k€/m3] • Ltcat : life time of catalyst [103 hrs] • Labour cost [man-year/MWth]: (l * cl) * 106 / (3,6 * pf) [k€/PJ fuel input/a] • l : labour demand [man-year/MWth] • cl : labour cost/wages [k€/man-year] • pf : annual operating hours at full load [h/a] Expert Group on Techno-Economic Issues (EGTEI) – Paris 04/2003
Components for the calculation of the OCvar for Combustion (2) • Waste disposal costd * cd * efunabated * / 103 [k€/PJ fuel input/a] • efunabated : unabated emission factor of pollutant [t pollutant/PJ fuel input] • d : demand for waste disposal [ton/ t pollutant removed] • cd : byproduct/waste disposal cost [€/ton] • : removal efficiency (= 1 - efabated/efunabated) • Fuel switch/efficiency improvement [k€/PJ fuel input/a] • SUM [(new consump/prod)i * (new price)i] – SUM [(old consump/prod)i * (old price)i] • Energy consumption (+) • Energy production (-) • Consumption [MJ/GJth input] • Fuel price [€/GJ] • Cost of low S fuellow S * clow S * 103 [k€/PJ fuel input/a] • low S : %S difference (%Sfuel old - %Sfuel new) [%S] • clow S : extra cost of low S fuel [€/GJ/%S] • Supplementary Cost [k€/PJ fuel input/a] • (for cost parameters others than mentioned above, e.g. process emissions) Expert Group on Techno-Economic Issues (EGTEI) – Paris 04/2003
