Public electricity and heat production is the largest source category re-garding both fuel consumption and greenhouse gas emissions for sta-tionary combustion. Figure 40 shows the time-series for fuel consump-tion and emissions of the pollutants included in the reporting to the Climate Convention.

The fuel consumption in electricity and heat production was 14 % higher in 2007 than in 1990. As discussed in Chapter 3 the fuel con-sumption fluctuates mainly as a consequence of electricity trade. Coal is the fuel that is affected the most by the fluctuating electricity trade.

Coal is the main fuel in the source category even in years with electric-ity import. The coal consumption in 2007 was 22 % lower than in 1990.

Natural gas is also an important fuel and the consumption of natural

part of the natural gas is combusted in gas engines (Figure 34). The consumption of municipal waste and biomass has increased.

The CO2 emission was 9 % lower in 2007 than in 1990. This decrease – in spite of a higher fuel consumption - is a result of the change of fuel discussed above.

For CH4 the emission increase until the mid-nineties is a result of the considerable number of lean-burn gas engines installed in CHP plants in Denmark in this period. The decline in later years is due to structural changes in the Danish electricity market, which means that the fuel consumption in gas engines has been decreasing (Figure 34). The emis-sion in 2007 was 8.5 times the 1990 emisemis-sion level.

The N2O emission was 17 % higher in 2007 than in 1990. The emission fluctuates similar to the fuel consumption.

The SO2 emission has decreased 93 % since 1990. This decrease is a re-sult of both lower sulphur content in fuels and installation and im-proved performance of desulphurisation plants.

The NOx emission has decreased 63 % due to installation of low NOx

burners, selective catalytic reduction (SCR) units and selective non-catalytic reduction (SNCR) units. The fluctuations in time-series follow the fluctuations in fuel consumption and electricity trade.

The emission of NMVOC in 2007 was 2.7 times the 1990 emission level.

This is a result of the large number of gas engines that has been in-stalled in Danish CHP plants as mentioned above.

The CO emission has increased 11 % since 1990. The fluctuations follow the fluctuations of the fuel consumption. In addition the emission from gas engines is considerable.

Petroleum refining is a small source category regarding both fuel con-sumption and greenhouse gas emissions for stationary combustion.

There are presently only two refineries operating in Denmark. Figure 41 shows the time-series for fuel consumption and emissions.

The significant decrease in both fuel consumption and emissions in 1996 is a result of the closure of a refinery.

The fuel consumption has increased 10 % since 1990 and the CO2 emis-sion has increased 8 %.

The reduction in CH4 emission from 1995 to 1999 is due to a combina-tion of the closure of a refinery and a change of emission factor.

The N2O emission has increased 12 %.

The SO2 emission has decreased 88 % and the NOx emission increased 9

%. In recent years data for both SO2 and NOx are plant specific data stated by the refineries.

The source category 2WKHUHQHUJ\LQGXVWULHV comprises natural gas con-sumption in the off-shore industry. Gas turbines are the main plant type. Figure 42 shows the time-series for fuel consumption and emis-sions.

The fuel consumption in 2007 was three times the consumption in 1990.

The CO2 emission follows the fuel consumption and the emission in 2007 was also three times the emission in 1990.

The two main sources for CH4 emission in 2007 was off-shore gas tur-bines and biogas fuelled gas engines. The increase in emission from 2003 to 2006 is due to an increase in biogas consumption in gas engines.

The CH4 emission factor for biogas fuelled gas engines (323 g/GJ) is much higher than emission factors for off-shore gas turbines (1.5 g/GJ) and this causes the increase in CH4 emission despite the low consump-tion of biogas in this emission source category.

The emissions from other pollutants follow the increase of fuel con-sumption.

Manufacturing industries and construction (Industry) consists of both stationary and mobile sources. In this chapter only stationary sources are included.

Figure 43-48 show the time-series for fuel consumption and emissions.

The data have not been disaggregated to industrial subcategories due to the fact that the Danish inventory is based on data for the industrial plants as a whole. Disaggregation to subcategories for the reporting to the Climate Convention is discussed in Chapter 13.8.

The total fuel consumption in industrial combustion has been rather stable since 1990; the consumption has increased 7 %. However, the consumption of gas has increased whereas the consumption of coal has decreased. The consumption of residual oil has decreased, but the con-sumption of petroleum coke increased. The biomass part of fuel have not changed considerably since 1990.

The GHG emission and the CO2 emission are both rather stable follow-ing the small fluctuations in fuel consumption. In spite of the 7 % in-crease of fuel consumption the CO2 emission in 2007 was almost the same as in 1990 due to the change of fuels.

The CH4 emission has increased from 1995-2000 and decreased again from 2004 onwards. In 2007 the emission was 43 % higher than in 1990.

The CH4 emission follows the consumption of natural gas in gas en-gines. Most industrial CHP plants based on gas engines came in opera-tion during 1995 to 1999. The decrease in later years is a result of the liberalisation of the electricity market.

The N2O emission follows the small fluctuations of the fuel consump-tion in industrial plants. In 2007 the emission was 2 % higher than in 1990.

The SO2 emission has decreased 57 % since 1990. This is mainly a result of lower consumption of residual oil in the industrial sector. Further the sulphur content of residual oil and several other fuels has de-creased since 1990 due to legislation and tax laws.

The NOx emission fluctuations follow the fuel consumption in the ce-ment production. However, the NOx emission has decreased 15 % since 1990 due to the reduced emission from industrial boilers in general.

The NMVOC emission has decreased 9 % since 1990. The decrease is a result of decreased emission from boilers due to the decrease of coal consumption that has a relatively high emission of NMVOC compared to other fuels. The emission from gas engines has however increased considerably after 1995 due to the increased fuel consumption that is a result of the installation of a large number of industrial CHP plants.

The NMVOC emission factor for gas engines are much higher than for emission factors for boilers regardless of the fuel.

The CO emission in 2007 was 15 % lower than in 1990. The main source of emission is combustion in mineral wool production. This emission follows the fuel comsumption in the mineral wool production plants.
