TL;DR: In this article, the energy and exergy analyses of three ORC-WHR configurations that use a coupling thermal oil circuit are presented, and the effect of evaporating pressure on the net power output, thermal efficiency increase, specific fuel consumption, and overall energy conversion efficiency is investigated, while the available exhaust thermal energy variation under different engine loads is determined through an experimentally validated mathematical model.

TL;DR: In this paper, a waste heat recovery system based on a dual-loop organic Rankine cycle (DORC) was optimized for a 2MW natural gas engine, and a sensitivity analysis was developed to study the effects of the condenser and evaporator pinch point temperature, turbine efficiency, and high evaporation pressure on the payback period (PBP), the specific investment cost (SIC), the net power output (Wnet), and the levelized cost of energy (LCOE).

TL;DR: A multiobjective optimization of an organic Rankine cycle (ORC) evaporator, operating with toluene as the working fluid, is presented in this paper for waste heat recovery from the exhaust gases of a 2 MW Jenbacher JMS 612 GS-N.L. gas internal combustion engine.

TL;DR: In this article, a comparative analysis of the performance of a hybrid system was conducted using a proposed model, built with historical data for meteorological conditions, wind speed, and solar radiation, which is integrated by a Southwest Wind Power Inc. wind turbine AIR 403, a proton-exchange membrane fuel cell (PEM), an electrolyzer, a solar panel, and a regulator based on proportional, integral, and derivative (PID) controllers to manipulate oxygen and hydrogen flow entering in the fuel cell.

TL;DR: In this paper, the authors presented a thermo-economic analysis of a simple ORC, ORC with recuperator (RORC) and a double-pressure ORC (DORC) integrated with a 2 MW Jenbacher JMS 612 GS-N.
