Exergy Analysis of Coal-Fired Power Plants in Ultra Supercritical Technology versus Integrated Gasification Combined Cycle

Through the potential possibilities of improving environmental criteria into the economic prospect, it is desirable to introduce the concept of green into business practices and associated perspectives. This article reviews the existing research on inventory problems in integrated or coordinated supply chains (SC) with consideration of environmental and carbon management. The study utilised the method of selection, practical criteria, screening, and synthesis, where a total of 35 articles were selected. An analysis of the papers has revealed that SC coordination problems that are often considered include order quantity, production quantity, delivery frequency and delivery quantity in minimising costs and carbon emissions (CO2). It was discovered that 38% of the studies considered the model's problem of production or transportation with a majority of studies, 71% considered carbon management in SC models. It is anticipated that this review will be useful for researchers who are interested in inventory modelling in the economic and environmental context by highlighting gaps for future studies and useful insights into the existing literature.

“…Globally, around 64% of total electrical energy in 2019 was still produced by burning fuels from fossil such as oil, natural gas, and coal 3) . The burning of fossil fuels and gasoline-ethanol produce air pollutants such as SOx, NOx, CO, VOCs (volatile organic compounds) 4) , carbon particulates, and ash which can cause air pollution 5) , environmental damage 6) , and increase greenhouse gases (GHGs) emissions 7) . These pollutants in a certain range significantly affect human health, such as the body's respiratory system, especially in children and the elderly 8) .…”

Nitrogen oxides (NOx), which can be found in the combustion process of coal-fired power plants, are pollutant gases that are dangerous to the environment and human life. The conventional technology used the dry method such as SCR (Selective Catalytic Reduction) and SNCR (Selective Non-Catalytic Reduction) to clean the gas stream from NOx contents. Alternatively, the polyvinylidene fluoride (PVDF) membrane module can be utilized to remove the NOx using oxidant solutions to absorb the NOx. The study aims to investigate the performance of the PVDF hollow fiber membrane module (HFMM) in removing NOx using absorbent solutions consists of H2O2 and HNO3. Throughout the experiment, the feed gas having 600 ppm NOx in nitrogen was introduced to the membrane fiber, then diffused in the pores of membrane to the outer surface of the fiber in the shell side of the HFMM, where the reaction between oxidant and NOx took place. The experimental results revealed that the efficiency of NOx elimination declines as the feed gas flow rate is increased. This study's maximum NOx reduction efficiency was 99.8%, at a 100 cm 3 /min feed gas flow.

“…Besides this, the PV system needs high investment for the installation of the PV panel. Another resource is the coal-fired (CF) power system that meets our demand for energy through power generation 10) . For example, coming to the real-world scenario, the power production structure in china, more than 70% of the coal power system 11) .…”

With the rapid prosperity of the global economy and industry, as the energy demand, many factors influence power-producing sectors, including government incentives, customer demand, production cost, eco-friendly, and investors investment. To analyze the cost-benefit-subsidy in power generator system under the evolutionary game setting, we considered two asymmetric game structures by coupling the photovoltaic (PV) power system and coal-fired (CF) power system. To model the asymmetric games for PV and CF, Game-1 considers respective cost and benefit, whereas, Game-2 deliberates cost, benefit, and government subsidy. We present both analytical and numerical approaches within this framework.
