“…In order to make full use of the existing coal-fired power plants' backup, the CFPP need to be decarbonized [4]. There are different routes, for example, double reheat technology [5], IGCC [6], carbon capture and storage (CCS) [7], and utilization of low-carbon/carbon-neutral fuels (e.g., biomass [8], hydrogen [9], and ammonia [10]).…”

<p>Coal-fired power plants (CFPP) are a significant resource for flexibility regulation of power systems containing a high proportion of renewable energy (RE). This paper presents an extended study of the technology for co-firing coal and ammonia, which can decarbonize CFPP. The excess RE produces green hydrogen, converted into green ammonia for CFPP combustion. Moreover, this system has energy storage features that can cope with short-term fluctuations and store and utilize RE seasonally. In this paper, this system’s complex coupled thermal and electrical rocesses are simplified and characterized as a mixed integer linear programming (MILP) model for the first time. Furthermore, the operation of the green ammonia co-firing system is simulated at two time scales of five days and a full year. Finally, sensitivity and efficiency analyses are performed. The results shows that as the maximum co-firing ratio of ammonia and coal increases, the total operation cost (TOC), carbon emission (CE), and RE curtailment shows a decreasing trend. Therefore, the ratio of ammonia-coal co-firing is recommended to be 25% to compromise the TOC and exhaust gas emission. In this situation, the TOC and CE will decrease by 8.59% and 12.74%, respectively, compared with the scenario without co-firing technology. The overall efficiency of green ammonia synthesis and combustion for generation is about 13.92%.</p>

The article presents results of thermodynamic analysis using a zero-dimensional mathematical models of a negative CO2 emission power plant. The developed cycle of a negative CO2 emission power plant allows the production of electricity using gasified sewage sludge as a main fuel. The negative emission can be achieved by the use this type of fuel which is already a “zero-emissive” energy source. Together with carbon capture installation, there is a possibility to decrease CO2 emission below the “zero” level. Developed models of a novel gas cycle which use selected codes allow the prediction of basic parameters of thermodynamic cycles such as output power, efficiency, combustion composition, exhaust temperature, etc. The paper presents results of thermodynamic analysis of two novel cycles, called PDF0 and PFD1, by using different thermodynamic codes. A comparison of results obtained by three different codes offered the chance to verify results because the experimental data are currently not available. The comparison of predictions between three different software in the literature is something new, according to studies made by authors. For gross efficiency (54.74%, 55.18%, and 52.00%), there is a similar relationship for turbine power output (155.9 kW, 157.19 kW, and 148.16 kW). Additionally, the chemical energy rate of the fuel is taken into account, which ultimately results in higher efficiencies for flue gases with increased steam production. A similar trend is assessed for increased CO2 in the flue gas. The developed precise models are particularly important for a carbon capture and storage (CCS) energy system, where relatively new devices mutually cooperate and their thermodynamic parameters affect those devices. Proposed software employs extended a gas–steam turbine cycle to determine the effect of cycle into environment. First of all, it should be stated that there is a slight influence of the software used on the results obtained, but the basic tendencies are the same, which makes it possible to analyze various types of thermodynamic cycles. Secondly, the possibility of a negative CO2 emission power plant and the positive environmental impact of the proposed solution has been demonstrated, which is also a novelty in the area of thermodynamic cycles.

“…Efficient assessment of the emission intensity of the most important GHGs, CO 2 and CH 4 , will be important for the formulation of policies to protect the environment (Le Quéré et al 2009, Gorchov Negron et al 2020, Liu et al 2020. Strong point source emission types account for the majority of total anthropogenic emissions, such as fossil combustion emissions from industrial production and methane leakage from human mine extraction (Schwandner et al 2017, Delgado et al 2018, Cheng et al 2021. The current methods for quantifying such emission intensities rely on emission inventories methods, such as the Open-source Data Inventory for Anthropogenic CO 2 (ODIAC), Emissions Database for Global Atmospheric Research (EDGAR), and Multi-resolution Emission Inventory for Chin (MEIC) (Oda et al 2018, Zheng et al 2020.…”

Development of the measurement-based carbon accounting means is of great importance to supplement the traditional inventory compilation. Mobile CO2/CH4 measurement provides a flexible way to inspect plant-scale CO2/CH4 emissions without the need to notify factories. In 2021, our team used a vehicle-based monitor system to conduct field campaigns in two cities and one industrial park in China, totaling 1143 km. Furthermore, we designed a model based on sample concentrations to evaluate CO2/CH4 emissions, EMISSION-PARTITION, which can be used to determine global optimal emission intensity and related dispersion parameters via intelligent algorithm (particle swarm optimization) and interior point penalty function. We evaluated the performance of EMISSION-PARTITION in chemical, coal washing, and waste incineration plants. The correlations between measured samples and rebuilt simulated ones were larger than 0.76, and RMSE was less than 11.7 mg/s, even with much fewer samples (25). This study demonstrated the wide applications of a vehicle-based monitoring system in detecting GHG emission sources.
