“…Yang et al [14] analyzed a combined power and ejector-refrigeration cycle that the power production section is an organic Rankine cycle. Fergani et al [15] proposed an organic Rankine cycle for the waste heat recovery for a cogeneration system used in the cement industry. They analyzed a cogeneration system from the exergy, exergoeconomic and exergoenvironmental perspective.…”

“…Although studies on the thermodynamic and economical assessment of Organic Rankine cycle are wide spread in literature (Fergani, Touil, & Morosuk, 2016;Hassoun & Dincer, 2015;Lecompte, Huisseune, van den Broek, Vanslambrouck, & De Paepe, 2015;Yang & Yeh, 2015), knowledge on the environmental impact of this technology under a life cycle perspective for energy production is still very limited. Some studies address the greenhouse gas reduction of the Organic Rankine cycle using solid waste in the far east (Imran, Park, Kim, Lee, & Usman, 2015;Sedpho, Sampattagul, Chaiyat, & Gheewala, 2017;Sununta, Sedpho, Gheewala, & Sampattagul, 2017).…”

Bioenergy has an important role to play in helping the UK meet its carbon target in 2050 and the European Renewable Energy Directive objectives for 2030. There are however uncertainties associated with the use of bioenergy, and whether or how much it contributes to greenhouse gas emission reductions. In order to help identifying environmental benefits and burdens associated with biomass use for energy production, an attributional life cycle assessment has been carried out of a biomass-fired CHP plant: the Heathrow Airport energy centre. This facility burns woodchips sourced from nearby forests providing 2 MWe of electricity and 8 MWth of thermal energy which delivers heat and cooling to Heathrow Terminal 2 and low temperature hot water to Terminal 5. A hot spot analysis is conducted to identify the process steps with the largest environmental impact, starting from the harvesting of the forest residue to the disposal of the boiler ash. A scenario analysis is performed to compare the impacts of the biomass plant against fossil alternatives and to identify which renewable energy sources, between biomass and MSW, should be prioritised for development and investment. The results show a reduction in GHG emissions from using biomass, with further benefits if the bottom ash is collected and re-used as a soil conditioner for landfarming or forestry. The paper also discusses the treatment of biogenic carbon in the assessment.

“…Most of investigations for ORC are focused on configuration optimization and single-optimization in ICEs waste heat recovery problems [5]- [7], [8]. However, several authors revealed that multi-objective optimization and multi-parameters solutions are advisable to achieve the best overall thermodynamic and economic performance for the subcritical ORC [9]- [12]. In order to fulfill optimization requirements, genetic algorithms (GA) have been extensively adopted for low grade waste heat recovery problems.…”

This paper presents a mathematical model of a bottoming Organic Rankine Cycle coupled to a 2l turbocharged gasoline engine to optimize the cycle from a thermoeconomic and sizing point of view. These criteria were optimized with different cycle values. Therefore, a methodology to optimize the ORC coupled to Waste Heat Recovery systems in vehicle applications is presented using a multiobjective optimization algorithm. Multi-objective optimization results show that the optimum solution depend on the importance of each objective to the final solution. Considering thermo-economic criteria as the main objective, greater sizes will be required. Considering sizing criteria as the main objective, higher thermoeconomic parameters will be obtained. Therefore, in order to select a singlesolution from the Pareto frontier, a multiple attribute decision-making method (TOPSIS) was implemented in order to take into account the preferences of the Decision Maker. Considering the weight factors 0.5 for Specific Investment Cost (SIC), 0.3 for the area of the heat exchangers (Atot) and 0.2 for Volume Coefficient (VC) and the boundaries of this particular application, the result is optimized with
