Exergy analysis of a Combined Cooling, Heating and Power system integrated with wind turbine and compressed air energy storage system
TL;DR: In this paper, a combined cooling, heating, and power system with a gas turbine, an organic Rankine cycle, and an absorption refrigeration system is presented, and the results show that under design condition, the system can generate 33.67kW electricity, 2.56kW cooling and 1.82kW hot water with a round trip energy efficiency of 53.94%.

Oxy-co-gasification of coal and biomass in an integrated gasification combined cycle (IGCC) power plant
Antonio Valero,Sergio Usón +1 more
TL;DR: In this paper, a model of an entrained flow gasifier, validated with nearby 3000 actual steady-state operation data (4800h), is used to study co-gasification of coal, petroleum coke and up to 10% of several types of biomass.

Thermodynamic analysis and optimization of a waste heat recovery system for proton exchange membrane fuel cell using transcritical carbon dioxide cycle and cold energy of liquefied natural gas
Mohammad Hossein Ahmadi,Amin Mohammadi,Fathollah Pourfayaz,Mehdi Mehrpooya,Mokhtar Bidi,Antonio Valero,Sergio Usón +6 more
TL;DR: In this paper, a hybrid system consisting of a transcritical carbon dioxide cycle and a liquefied natural gas cycle is proposed to recover the waste heat produced in a proton exchange membrane fuel cell.

Exergy analysis as a tool for the integration of very complex energy systems: The case of carbonation/calcination CO2 systems in existing coal power plants
TL;DR: In this paper, a synthesis of pinch analysis and second law analysis is used to show the optimum window design of the integration of a calcium looping cycle into an existing coal power plant for CO2 capture.

Application of Thermoeconomics to Industrial Ecology
TL;DR: Thermoeconomics, commonly used for the optimization and diagnosis of energy systems, is proposed as a tool for the characterization of Industrial Ecology by extending the thermoeconomic process of the cost formation of wastes in order to consider their use as input for other processes.
