Possibility for CO2 Emissions Reduction in Croatian Energy Sector by Application of Heat Pumps and Solar Thermal in Households

Depending on available technologies many scenarios can be made to achieve greenhouse gases emissions reduction. This paper describes a scenario whose goal is to reduce CO2 emissions in Croatian energy sector by applying heat pumps and solar thermal in households. The scenario has been made and simulated in EnergyPLAN software developed at Aalborg University, Denmark. Main idea is to meet a portion of heat demand in households with heat pumps (50 per cent) and solar thermal collectors (20 per cent), and main feature is effectiveness of heat pumps from emissions reduction aspect compared to effectiveness of natural gas or oil driven boilers. In order to do such comparison an entire energy transformation chain has to be taken into concern. This feature is included in preliminary calculations which have shown reductions of CO2 emissions (by 4.05 per cent) and primary energy supply (by 3.2 per cent). Regarding to Energy Sector Development Strategy of the Republic of Croatia which assumes commissioning new power plants, further analysis has been made to estimate CO2 emissions reduction rates by the year 2020. The analysis will show whether previous results can be achieved or even improved with commissioned power plants. To achieve such results optimal heat pumps’ COP (or SPF) will also be calculated by the analysis in this paper. As a conclusion economic assessment of the scenario has been made to decide whether it can be cost effective.
