Abstract

U ovom radu je obrađena mogućnost uzgoja energetskih nasada na neiskorištenom poljoprivrednom zemljištu u Republici Hrvatskoj. Hrvatska raspolaže s gotovo 3 000 000 ha poljoprivrednog zemljišta, ali se koristi samo oko 1 000 000 ha. Stoga je očito da postoji značajan potencijal koji se može koristiti mnogo efikasnije nego što je to danas slučaj. Izložene su vrste kultura kratkih ophodnji i energetskih usjeva koji se trenutno koriste u Europi za energetsku eksploataciju te su opisane njihove karakteristike koje su važne za primjenu na zemljištima koja su uzeta u obzir i za energetsku eksploataciju. Također je analiziran potencijal tako kultiviranih zemljišta po županijama u Hrvatskoj i elaboriran energetski i tehnički potencijal. Potom se pomoću optimizacijskog modela odredilo 5 makrolokacija u Hrvatskoj za energetska postrojenja instalirane snage do 15 MWe koja bi bila pogonjena na biomasu pridobivenu iz energetskih nasada. Za ta postrojenja, provedena je tehno-ekonomska analiza i analiza osjetljivosti s obzirom na promjene vrijednosti značajnih parametara. Potom je dan zaključak o ovom načinu korištenja neiskorištenog potencijala poljoprivrednog zemljišta za energetsku upotrebu koristeći pritom energetske nasade koji su već u Europi uspostavljeni i korišteni, a čija se korist ogleda, ne samo u pridobivenoj biomasi, nego i u povoljnim utjecajima na zemljište, biološku raznolikost i korištenje kao ponor za stakleničke plinove – naročito CO2.

Abstract (english)

In this paper the possibility of growing energy crops on unused agricultural land in the Republic of Croatia is examined. Croatia has nearly three million hectares of agricultural land, but it is only about one million hectares in use. Therefore, it is obvious that there is a significant potential that can be used much more efficiently than it is the case today. Types of crops and short rotation coppice currently used in Europe for energy exploitation and their characteristics that are important for application on soil are taken into account. The potential of land cultivated in such fashion in counties in Croatia and energy and technical potential is elaborated. Then, using the optimization model, five macro-locations in Croatia are selected for power plants with installed capacity up to 15 MW that would be driven by the biomass acquired from energy crops. For such plants, techno-economic analysis and sensitivity analysis with respect to the value of the significant parameters was carried out. Then the conclusion for this way of exploiting unused potential of agricultural land for energy use by utilizing energy crops that are already established in Europe and used, and whose benefit is reflected not only in aquired biomass, but also in the favorable impacts on land, biodiversity and use as a sink for greenhouse gases - particularly CO2.
