The comparision of a basic and a dual-pressure ORC (Organic Rankine Cycle): Geothermal Power Plant Velika Ciglena case study

Energy and economic analysis of geothermal–solar trigeneration systems: A case study for a hotel building in Ischia

“…This difference is explained by the relatively high average annual temperature of the cooling air in the condenser (15°C), which has a more unfavourable influence on the condensing pressure in the Kalina cycle than in the ORC one (6.35 vs. 0.68 bar). In a recent work, Guzović et al [7], in order to improve the geothermal energy utilisation, investigated the replacement of a basic ORC with a dual-pressure ORC. These dual-pressure cycles introduce an additional pressure level, leading to an evaporation occurring at two different temperatures (high-pressure and a low-pressure loop power cycles).…”

Parametric analysis and optimization of a small-scale radial turbine for Organic Rankine Cycle

“…Tempesti et al [1] and Guzovic et al [11] carried out thermodynamic modelling of a single and a dual pressure ORC with solar and geothermal heat. They showed that R245fa and isopentane exhibit the best performance in terms of cycle and exergy efficiencies and minimum solar collector area with the dual pressure cycle.…”

A review of developments in technologies and research that have had a direct measurable impact on sustainability considering the Paris agreement on climate change

“…In [52] authors are analysing basic and dual-pressure ORC with the implementation done on a specific geothermal plant, as s case study. One of the prerequisite of geothermal energy utilization is the creation of quality geothermal maps, which was the focus of [53], where neural networks were used to determine potentials at three different depths.…”
