Summary

Renewable energy systems play a major role in the reduction of CO2 emissions in industrial processes. However, selecting a suitable renewable energy system is difficult since the development of standardized concepts for assessing the ecological and techno-economic performance of such a system is lagging behind the advances made in the technologies themselves. 
This article introduces a diagram-based approach for the quick evaluation and comparison of energy systems by using the vapor compression heat pump cycle as an example. On the basis of known technical key parameters of the heat pump cycle, transparent and highly flexible performance indicators are deduced like the relative energy cost and CO2 savings during heating operation. The proposed evaluation concept demonstrates efficient practical use for economic and ecological technology comparison in several example scenarios. Aparameter study shows the influence of key parameters in the heat pump cycle with regards to the system savings.
