“…These values indicate the amount of biomehtane/biogas produced per one gram of fresh substrate. It is worth mentioning that the biogas has an average low calorific value (LCV) of 10 MJ kg −1 [124], and an average high calorific value (NCV) of 20-21 MJ kg −1 at methane content of 55% [75,125,126], where the methane has an NCV of 50 MJ kg −1 [127]. Table 1 adapts the calculation method used by Achinas and coauthors [126] in their research to estimate the electricity produced from fresh material (estimating 35% electrical efficiency combined heat power, heating value of 21 MJ m −3 , 55% methane content, 3.6 MJ (kWh) −1 ).…”

The biogas production technology has improved over the last years for the aim of reducing the costs of the process, increasing the biogas yields, and minimizing the greenhouse gas emissions. To obtain a stable and efficient biogas production, there are several design considerations and operational parameters to be taken into account. Besides, adapting the process to unanticipated conditions can be achieved by adequate monitoring of various operational parameters. This paper reviews the research that has been conducted over the last years. This review paper summarizes the developments in biogas design and operation, while highlighting the main factors that affect the efficiency of the anaerobic digestion process. The study’s outcomes revealed that the optimum operational values of the main parameters may vary from one biogas plant to another. Additionally, the negative conditions that should be avoided while operating a biogas plant were identified.

“…Burning the low-calorific gaseous fuel produced by oil shale gasification in industrial turbines or external combustion chamber with a gas turbine inlet temperature of 1250 °C at a pressure ratio of 10-15 is capable of achieving plant heat rates of about 7.8 (+0.1) x 10 kJ per kWh produced at relatively low capital cost [76][77][78]. The simple combined-cycle arrangement is more environmentally-friendly because less pollutants per kWh of electricity generated would be produced compared with FBC or pulverised fuel technologies.…”

In this paper, different ways for developing indigenous oil shale resources and their important role in reducing the dependence of Jordan on imported oil are assessed. Also, the Government's plan and strategy with respect to premature or short sighted and loose energy policy is discussed. Oil shale is the major indigenous fossil fuel in Jordan, and it is not utilised at present.During the next few years, a commercial oil shale complex could be developed in the country to produce shale oil and/or electricity substituting for imported crude oil and petroleum products. The future beneficial use of the vast oil shale deposits depends not only on the development of suitable process economics but also on the availability of suitable environmental controls. Thus, oil shale's future will be a mixture of promise and risk. Oil shale can still be considered Jordan's most extensive domestic fossil-fuel source well throughout the 21st century and beyond. However, the Government's position is not clear enough with regard to what should be done in order to utilise the oil shale resources in a wise way. So, comprehensive scientific research, feasibility studies, legislation and best practices codes as main parts of a national energy plane should be addressed and developed in order to decide about the most suitable technology for Jordan.

“…One of the efforts that can be made is to optimize the performance of power plants as the main supplier of human electricity needs. Gas turbine generator (GTG) is a component commonly used in power plants with fuel sources in the form of coal, natural gas, and distillate oil [3][4][5][6]. The compressor, combustion chambers, and turbines are the main components that make up a gas power plant or gas turbine generator system [5][6][7][8][9][10][11].…”

Increasing electricity production must continue to be pursued to meet the increasing electricity needs of the community. One of the efforts that engineers can make is to improve the performance of the main suppliers of electricity needs. It is impossible to separate the role of the system's components from the performance of the gas turbine generator. This journal discusses exergy and energy analysis in the gas turbine generator of X combined cycle power plant through simulation with Cycle-Tempo software. The simulation results show that the highest system energy efficiency is owned by the gas turbine generator unit 2.3 of 35.541%, with a system exergy efficiency of 34.069%. The lowest system energy efficiency is owned by the gas turbine generator unit 2.1 of 31.669%, with a system exergy efficiency of 30.355%. The gas turbine generator component with the lowest exergy efficiency occurs in the combustion chamber of the gas turbine generator unit 2.2 of 76.81%, with exergy destruction of 92.581 MW. Meanwhile, the gas turbine generator component with the highest exergy efficiency occurred in the turbine of the gas turbine generator unit 2.3 of 96.81%, with exergy destruction of 9.762 MW. The simulation results that have been carried out show that the performance of the components in the gas turbine generator is still in good performance, with the lowest exergy efficiency above 75%.
