Forests – Energy Forests Development, Speaker Mr. János Horváth,
Geomontan Co. The presentation was held by Mr. János Horváth. The topic of Mr. Horváth’s presentation was the Energy Forest Development on Central-European areas, where agricultural production is uneconomical. One of the main
objectives of the Energy Forests Project is to determine how much energy
could be produced from wood if energy forests were planted on unproductive
lands.
Hungary’s total
area is 9 303 000 Ha, the low qualitiy land is estimated about 1 790 000
Ha. The Hungarian renewable energy consumption today is 38 PJ/year, (3,6
% of the total consumption). About 2,8% of all renewables is biomass,
mainly firewood. By 2010 the share of renewables will have to be raised
to 12%. Only 0,5% of the total Hungarian electricity supply has come from
renewables in 2003. By the end of the decade this should be increased
sevenfold to 3,6%.
There are several aspects which influence the
status of renewable energies:
Hungary's Biomass
Potential
Mr. Horváth also mentioned that Hungary’s estimated total biomass reserves are around 350-360 million tons, and the annual biomass formation is around 105-110 million tons. The gross energy content of the annual biomass formation is 1185 PJ. It is much larger than the country’s total energy consumption, which is 1040 PJ/year. Vegetation stores about 30,4 million tons of carbon annually, which is more than twice as much as the carbon content of coal extracted from the mines.
About further Hungarian
possibilities Mr. Horváth mentioned that Energy forests if planted
on 1,79 Million Ha low soil quality land could provide: 14,3 – 25,1
million tons of woodmass, which is equivalent to 171-301 PJ of energy.
Even when energy forests - planted on 1 Million Ha of non-cultivated arable
land – they could provide 8-14 miilion tons woodmass which is equivalent
to 96-168 PJ of energy.In his conclusion
Mr. Horváth mentioned that energy forests could meet 9-29% of the
annual Hungarian energy demand (depending also on the efficiency of conversion
process). |
