This research is concerned with the design and analysis of a geothermal based multi-generation system by applying both conventional and advanced exergy and exergoeconomic concepts. The proposed energy system consists of a dual-organic Rankine cycle (ORC) to vaporize liquefied natural gas (LNG) and produce electricity. A proton exchange membrane(PEM) electrolyzer is employed to produce hydrogen ...

Editorial Topic 4 of the Renewable Energy Program of the Helmholtz Association focusses inter alia on the sustainable and cost-efficient use of geothermal reservoirs for base-load supply of heat and electricity by EGS. Current EGS projects show the limitations of such systems. Firstly, the localization of a potential reservoir prior to drilling still remains a major challenge. Secondly, the min...

In the perspective of increasing the share of renewable energies to mitigate global warming and to respond to fossil resources depletion, the use of geothermal resources for the polygeneration of energy services has gained interest and is expected to know an important development in the future. Some of the major issues linked with the use of geothermal energy concern the increase of the efficie...

Hybrid solar and geothermal utilisation is a promising option for effective exploitation of renewable energy sources. Concentrated power (CSP) systems with preheating are acknowledged as an attractive solution, supercritical CO2 (SCO2) cycle adopted generation thanks to the favourable properties offered by working fluid. In order further improve overall performance such systems, organic Rankine...
