CHPM2030 Deliverable D5.2: Economic feasibility assessment methodology

Deliverable is focused on the description of economic related issues of two levels of the CHPM (Combined Heat, Power and Metal extraction). Energy level, represented by enhanced geothermal system (EGS), is not a current rival to other conventional energy sources due to very high capital and operational costs. Simulations predict competitiveness of EGS in time framework
of CHPM development. Extraction of metals from geothermal fluid is a commercially untested technology, which has no clearly defined operation costs. This makes the economic feasibility assessment difficult. Theoretical models suggest that positive economic feasibility can be achieved only on sites with higher concentrations of dissolved metals in brines and/or higher fluid flow.
