“…It concluded that the low price of carbon in the market making CCS unfavorable in globe, while high carbon prices shall be able to make it economical. High carbon prices and commissioning of the ultra-supercritical power plant along with CCS will reduce the cost almost 14-35% during 2020-2050 and CCS will face stiff competition from renewable energy in the future (Kumar et al, 2018).…”

Background: The drastically increasing share of fossil fuel supply to meet the rapidly growing electricity demand resulting in increasing Carbon dioxide (CO2) emissions, is the major concern in Thailand. In 2015, fossil fuels used in electricity generation in Thailand accounted for around 85.3% of the total electricity generation. Aim: The aim of the study is to analyze carbon dioxide mitigation options under the cleaner supply-side option beyond the Intended Nationally Determined Contribution (INDC) of Thailand. Methods: In this study, the Long-range Energy Planning (LEAP) model is used to analyze the share of electricity generation and CO2 mitigation from four main different scenarios, namely Business-as-Usual (BAU), Renewable Energy (RE), Carbon Capture Storage (CCS), and Carbon Tax (CT) scenarios during 2015 to 2050. The BAU scenario is constructed following the power development targets of the Power Development Plan in 2015. Results: The results illustrate that in the BAU scenario, electricity generation and carbon dioxide emissions from the power sector will increase by 57.7% and 37.3%, respectively in 2050 as compared to 2015. The imposition of carbon tax of $20/tCO2 from 2020 and an increase to $500/t CO2 by 2050 will have a high potential to reduce CO2 emissions from the power sector as compared with other scenarios. Conclusion: Results show that except for the RE scenarios considering the lower share of solar and biomass, all scenarios would help Thailand in achieving the target of INDC by 2030. Results provide that the share of imported electricity is higher with the imposition of carbon tax as compared to the scenarios with the promotion of renewable energy, CCS and EV technology.

“…Since the last few years, Pakistan has faced a severe energy crisis while its population is increasing at an annual growth rate of 2.4 % with an approximate population growth of 18 million per year [3]. Pakistan's energy requirements, which is supplied mainly by fossil fuels (54 %) and some biomass fuels [4], are increasing due to its population growth similar to its two neighbours, China and India [5,6]. All these sources of energy are the main causes of GHG emissions, especially emissions of CO 2 .…”

“…Considering the usage of biomass in Pakistan, no precautions are taken due to lack of knowledge, and this fuel is usually burned in open environment [3]. The GHG emissions from Pakistan are relatively low compared to many other countries especially to its two neighbours, China and India, which are among the top three global emitters of CO 2 [5]. CO 2 emissions per capita in Pakistan in 2016 was 0.85 t, which was much lower than China and India with 6.65 and 1.65 t, respectively [5].…”

Reduction of Greenhouse Gas Emissions from Gas, Oil, and Coal Power Plants in Pakistan by Carbon Capture and Storage (CCS): A Review

2020

The production of energy in Pakistan as a developing country mainly depends on consumption of fossil fuels, which are the main sources of greenhouse gas (GHG) emissions. These emissions can be mitigated by implementing carbon capture and storage (CCS) in running plants. An overview of the current and future potentials of Pakistan for CCS is provided, indicating a great potential for this technology to capture CO 2 emissions. The amine CO 2 capture process as the most mature procedure is currently applied in many oil and gas companies in Pakistan, which can be employed to capture CO 2 from other industries as well. Pakistan has a great CO 2 storage potential in oil, gas, and coal fields and in saline aquifer as well as significant resources of Mg and Ca silicates suitable as feedstock in the carbon mineralization process. For further development and implementation of CCS technologies in Pakistan, economic and policy barriers as the main obstacles should be alleviated.

“…The most complex analyses of power plants and its components are 3E (Energy, Exergy and Economic/ Environmental) [38,39] and 4E (Energy, Exergy, Economic and Environmental) [40,41] analyses, which provide a complete insight into a power plant operation from various aspects. Such analyses are often used for power plant optimization and research of the pollutants reduction possibilities [42,43]. A critical review of 4E analysis for a various power plants can be found in [44].…”

Comparison of Energy Flow Stream and Isentropic Method for Steam Turbine Energy Analysis

et al. 2019

In this paper, a comparison of two different methods for a steam turbine energy analysis is presented. A high-pressure steam turbine from a supercritical thermal power plant (HPT) was analysed at three different turbine loads using the energy flow stream (EFS) method and isentropic (IS) method. The EFS method is based on steam turbine input and output energy flow streams and on the real steam turbine produced power. The method is highly dependable on the steam mass flow rate lost through the turbine gland seals. The IS method is based on a comparison of turbine steam expansion processes. Observed energy analysis methods cannot be directly compared because they are based on different sources of steam turbine energy losses, so, an overall steam turbine energy analysis is presented. Unlike most steam turbines from the literature, the analysed HPT did not have the highest overall energy efficiency at a full load due to exceeding the water/steam critical pressure at the turbine inlet during such operation.
