Environomic optimal design of geothermal conversion systems using life cycle assessment
Recent years have seen an increased interest in reducing greenhouse gases emissions, reducing the consumption of non-renewable energy resources, and increasing energy supply security. This interest has created improved opportunities for renewable energy systems development, including the use of geothermal energy for electricity and/or heat production. Corresponding to this interest, the environmental impact of renewable energy systems, including geothermal energy, have become an important topic of study. To evaluate these impacts, a conventional life cycle assessment (LCA) is commonly used.
This paper proposed a strategy to integrate life cycle assessment (LCA) in thermo-economic model used to design geothermal conversion systems. Swiss and Polish case studies are considered for the validation of this methodology. The superstructure of system consist of the superstructure of exploitable resources with the superstructure of conversion technologies and multiple demand profiles for Swiss city Nyon and Polish city Konin.
The emphasis is put on the maximization of exergy efficiency of geothermal conversion systems and the minimization of their generated life-cycle assessment impacts.
The proposed strategy can be adjusted to determine the optimal exploitations schemes and system configuration across the multiple periods. The evaluation of the methodology can give important tool to evaluate decision-making problems.
