Abstract

Rad predstavlja detaljnu analizu potencijala sunčeve energije i analizu isplativosti instaliranja fotonaponskih sustava u Panonskim dijelovima Hrvatske i Srbije. Uspoređeni su tarifni sustavi za poticanje proizvodnje iz električne energije pomoću mrežnih fotonaponskih sustava i time rezultirajućom dobiti s jedne strane s trenutnim investicijskim i pretpostavljenim troškovima održavanja i pogona tijekom životnog vijeka s druge strane. PVGIS – PhotoVoltaic Geographical Information System korišten je za podatke o sunčevom zračenju i proračunu očekivane proizvodnje električne energije iz fotonaponskih sustava nazivne snage do 10 kW, 30 kW, 300 kW i preko 300 kW (prema različitim poticajnim tarifama u Hrvatskoj) Rezultati pokazuju značajne razlike u razvoju fotonaponskog tržišta u Hrvatskoj i Srbiji i potrebu daljnjeg poboljšanja sustava poticaja i legislative u Srbiji kako bi se instaliranje fotonaponskih sustava učinilo izvodivim., The paper presents detailed comparison of solar energy potentials and cost-benefit analysis of installing photovoltaic power systems in Pannonian parts of Croatia and Serbia. Feed-in tariff systems for incitement of the electricity production from on-grid photovoltaic power systems and the resulting benefits on one side and the current investment and the projected life-time operation and maintenance cost on the other side, have been compared. PVGIS – PhotoVoltaic Geographical Information System have been used for data on solar irradiation and calculation of expected electricity production from PV systems with rated power up to 10 kW, 30 kW, 300 kW and over 300 kW (according to the different feed-in tariffs in Croatia). The results indicate substantial differences in PV markets development in Croatia and Serbia and the necessity to improve feed-in tariffs and legislation in Serbia in order to make the installation of PV systems feasible.

Abstract

Geothermal heat pumps have several advantages over conventional heating and cooling systems. They can operate in both winter and summer, have high efficiencies, and do not directly emit any greenhouse gases during operation. Investors (in developing countries) can use Clean Development Mechanism as a source of financing for new or existing renewable energy facilities by selling Certified Emission Reductions credits (CERs), which represent the amount of CO2 emission (1 CER¼1 tCO2eq) that is avoided using renewable energy. The aim of this paper is to analyze the possibility of CO2 reduction by using geothermal heat pumps for fossil fuel displacement with applying Clean Development Mechanism. Results have shown that by using geothermal heat pumps during a 7-year crediting period, the estimated emission reduction would be 79.45 tCO2 (equal to 80 CERs), enabling the investor to achieve profit from selling 80 CERs and thus helping to fund the proposed project activity. Three main factors which influence the amount of CO2 reduction have been identified: carbon-dioxide emission factor for electricity source, efficiency of technology used for baseline scenario, and coefficient of performance (COP) of heat pumps.
