Development of a Low Temperature Geothermal Organic Rankine Cycle Standard
Low temperature geothermal systems are an abundant energy resource in New Zealand with over 260 sites with a resource temperature of 150°C and lower. The Organic Rankine Cycle (ORC) is the standard process for low temperature energy conversion with commercial ORCs utilizing temperatures as low as 90°C, with one site at Chena, Alaska (discussed below) utilizing temperatures as low as 74°C. The a...
متن کاملComparative investigation of working fluids for an organic Rankine cycle with geothermal water
In this paper, the thermodynamic investigation on the use of geothermal water (130 ◦C as maximum) for power generation through a basic Rankine has been presented together with obtained main results. Six typical organic working fluids (i.e., R245fa, R141b, R290, R600, R152a, and 134a) were studied with modifying the input pressure and temperature to the turbine. The results show that there are n...
متن کاملParametric Assessment of a Novel Geothermal Multi-Generation Equipped with Dual-Organic Rankine Liquefied Natural Gas Regasification Cycle Using Advanced Exergy and Exergoeconomic-Based Analyses
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 ...
متن کاملSensitivity analysis of system parameters on the performance of the Organic Rankine Cycle system for binary-cycle geothermal powerplants
The main purpose of this paper is to analyze the sensitivity of system parameters to the performance of the Organic Rankine Cycle (ORC) system quantitatively. A thermodynamic model of the ORC system for binary-cycle geothermal power plants has been developed and verified. The system parameters, such as working fluid, superheat temperature, pinch temperature difference in evaporator and condense...
متن کاملOptimal Heat Source Temperature For Supercritical Organic Rankine Cycle
Organic Rankine Cycle (ORC) enables power generation from lowto medium temperature heat sources. In an ORC, the organic medium shows different performances for different heat source temperatures. For a range of heat source temperatures, one temperature can be always identified corresponding to the best thermal match between the heat transfer fluid and working fluid. This temperature is defined ...
