In this Deliverable we present the techno-economic analysis of the two heat pump systems: First, the techno-economic analysis of the gas-driven sorption heat pump developed is given. The analysis is mainly based on the methodology proposed by the EN 12309 series, where the Seasonal Gas Utilization Efficiency (SGUE) ratio is calculated to evaluate the efficiency of the machine concerning the use of the main heat source (CH4 in this case) and to evaluate how many of the available energy is transferred to the user. The costs estimation presented in this report have been developed starting from the experiences acquired during the development of the Perugia’s Demo-site, but are not specifically based on this demo due to some of his peculiar (e.g. soil characteristics, historical building, etc.) characteristic that may not be representative of a general case study. Secondly, the assessment for the electrically driven heat pump system is shown. For the given assumptions, we calculated a payback time of approx. 13 years for a GSHP compared to 20 years for an AWHP. The most important conclusion that can be drawn from the sensitivity analysis for the GSHP, is that the quickest way to make heat pumps more profitable, would be increasing the gas price, which already happened in the recent months but has also pulled the price of electricity. The profitability boost would even be bigger if the gas price increase would be combined with a decrease in electricity price. Changing to heat pump systems could also mean a 45%-60% reduction in CO2 emissions, which would contribute significantly to the set climate goals if it is done on a large scale. Especially combining heat pump and PV systems – which is not considered actively within GEOFIT, but is a valid option - would increase these benefits significantly compared to installing heat pumps only.

Abstract
In this Deliverable we present the techno-economic analysis of the two heat pump systems: First, the techno-economic analysis of the gas-driven sorption heat pump developed is given. The analysis is mainly based on the methodology proposed by the EN 12309 series, where the Seasonal Gas Utilization Efficiency (SGUE) ratio is calculated to evaluate the efficiency of the machine concerning the use of the main heat source (CH4 in this case) and to evaluate how many of the available energy is transferred to the user. The costs estimation presented in this report have been developed starting from the experiences acquired during the development of the Perugia’s Demo-site, but are not specifically based on this demo due to some of his peculiar (e.g. soil characteristics, historical building, etc.) characteristic that may not be representative of a general case study. Secondly, the assessment for the electrically driven heat pump system is shown. For the given assumptions, we calculated a payback time of approx. 13 years for a GSHP compared to 20 years for an AWHP. The most important conclusion that can be drawn from the sensitivity analysis for the GSHP, is that the quickest way to make heat pumps more profitable, would be increasing the gas price, which already happened in the recent months but has also pulled the price of electricity. The profitability boost would even be bigger if the gas price increase would be combined with a decrease in electricity price. Changing to heat pump systems could also mean a 45%-60% reduction in CO2 emissions, which would contribute significantly to the set climate goals if it is done on a large scale. Especially combining heat pump and PV systems – which is not considered actively within GEOFIT, but is a valid option - would increase these benefits significantly compared to installing heat pumps only.File | Dimensione | Formato | |
