Electricity production mix of Slovakia

Nuclear; 52,39% Hydro; 20,31% Natural_gas; 7,93% Lignite; 7,82% Hard_coal; 5,01% Grid_losses; 3,30% Biomass_solid; 2,18% Own_consumpt; 2,17% Heavy fuel oil; 2,16% Coal_gases; 1,83% Others; 1,37%

Others less than 0,5% : WtE, biogas, photovoltaics

ODP

• Ozone layer depletion (ODP) is relative value that indicates the

potential of a technology to decrease ozone layer

• The Ozone Depletion Potential (ODP) defined as the ozone depletion

produced by a unit of the gas converted into ozone depletion values produced by the reference substance trichlorofluoromethane (CCl3F = CFC-11) is the meter which is used to assess the importance of the effect produced by the various gases

• During incineration wastes for energy, power plant generate dioxins,

which have a negative impact on ozone layer

AP

• Acid gases that are released into the air or resulting from the

reaction of non-acid components of the emissions are taken up by atmospheric precipitations and the falling “acid rain” forms an acid input which is absorbed by plants, soil and surface waters

• The Acidification Potential is a meter of the disposition of a unit
• f the mass of a component to release H+ protones, compared to

the reference substance SO2

Conclusion

• In presented data from GaBi software we can see that Ozone

Depletion Potential of Slovakia is much lower than European Union avarage (EU27mix). The highes values are in biogas and waste.

• In case of Acidification Potential Slovakia is above the EU
• avarage. The biggest share of AP is in technologies burning fossil

fuels followed by biogas and biomas.
