A hybrid system based on an existing recuperated microturbine and a pre-commercially available high temperature tubular solid oxide fuel cell is modeled in order to study its performance. Individual models are developed for the microturbine and fuel cell generator and merged into a single one in order to set up the hybrid system. The model utilizes performance maps for the compressor and turbine components for the part load operation. The full and partial load exergetic performance is studied and the amounts of exergy destruction and efficiency of each hybrid system component are presented, in order to evaluate the irreversibilities and thermodynamic inefficiencies. Moreover, the effects of various performance parameters such as fuel cell stack temperature and fuel utilization factor are investigated. Based on the available results, suggestions are given in order to reduce the overall system irreversibility. Finally, the environmental impact of the hybrid system operation is evaluated.

Energy Production System

In the study, the energy that monocrystalline, polycrystalline and thin-film solar panels of equal power produce was combined on the electronic board and hybrid solar system was created. Fuel cell was added to this hybrid system, so providing diversity in energy production sources. The produced electrical energy flow was controlled by using different energy sources types together. Battery groups were connected to the control circuit for storing the produced energy. Also, the receiver loads, which would redirect the flow energy were added to the control circuit. The electrical energy each solar panel produced, the electric current the load pulled and battery charge-discharge conditions were monitored through the control system designed to control the flow energy. These data were recorded at regular intervals with C# software. The control algorithms that are appropriate for system’s energy flow were determined and consumers were fed with the electrical energy produced by the hybrid system, and the battery was charged at the same time. The recorded data were analyzed and the energy each solar panel produced, the rates of benefiting from produced electricity through applied algorithms, and how much consumers were fed with the energy accumulated on the battery group were approximately determined.

Abstract The production of liquefied natural gas (LNG) is a high energy-consuming process. The study of ways to reduce energy consumption and consequently to reduce operational costs is imperative. Toward this purpose, this study proposes a hybrid system adopting a mixed refrigerant for the liquefaction of natural gas that is precooled with an ammonia/water absorption refrigeration (AR) cycle utilizing the exhaust heat of a molten carbonate fuel cell, 700°C and 2.74 bar, coupled with a gas turbine and a bottoming Brayton super-critical carbon dioxide cycle. The inauguration of the ammonia/water AR cycle to the LNG process increases the cooling load of the cycle by 10%, providing a 28.3-MW cooling load duty while having a 0.45 coefficient of performance. Employing the hybrid system reduces energy consumption, attaining 85% overall thermal efficiency, 53% electrical efficiency and 35% fuel cell efficiency. The hybrid system produces 6300 kg.mol.h−1 of LNG and 146.55 MW of electrical power. Thereafter, exergy and sensitivity analyses are implemented and, accordingly, the fuel cell had an 83% share of the exergy destruction and the whole system obtained a 95% exergy efficiency.
