Most of textile dyes with nonbiodegradable, toxic and carcinogenic features could cause adverse effects for ecosystems and human health. A little studied sorbent - aerogel - a substance with a low density in the solid state was used in experiments. This material is lightweight and has a large surface area. Aerogels obtained not from petroleum but from cellulose, chitosan, lignin or pectin have good sorption properties for removing organic pollutants from wastewater. The aim of this study was to determine the adsorption efficiency of the removal of naphthol green B from artificially contaminated water using sorbent synthesized from paper waste. Cellulose aerogel, which was prepared from office paper and cardboard waste, was used in experimental research. Adsorption capacity values ranged from 0.12 mg/g to 0.83 mg/g. It can be stated that the change in the pH of the solution after the sorption process did not affect the sorption result and optical density of investigated solution. The surface area of aerogel changed after sorption process: the gaps between the fibers have decreased, the surface of aerogel became smoother.","PeriodicalId":350012,"journal":{"name":"2022 International Conference and Utility Exhibition on Energy, Environment and Climate Change (ICUE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127453533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Organic, organic-inorganic hybrid lead-based perovskite compounds are becoming commercially appealing as absorber materials in the majority of perovskite solar cells due to high PCE (power conversion efficiency), low cost, availability of materials, and ease of production. However, as mentioned above, lead-based organic perovskite solar cells are unstable in open space. Nowadays, Sn-based inorganic perovskites are becoming more popular than lead-based perovskites as Pb-based perovskite solar cells are toxic and not environment-friendly. In this study, the thickness, doping density, defect density, energy bandgap of the absorber, and ETL (electron transport layer) and HTL (hole transport layer) materials of the cell are optimized using SCAPS-1D simulator. The final structure is FTO/ZnO/CsSnGeI3/NiO/Cu2O, where FTO works as TCO (transparent conducting oxide) layer. The optimized structure offered an open-circuit voltage (Voc) of 1.245V, a short-circuit current (Jsc) of 28.189 mA/cm2, a Fill Factor (FF) of 89.97%, and an overall PCE of 31.57%. According to the literature, this is the highest PCE for the CsSnGeI3 perovskite solar cell with all-inorganic layers. The proposed optimized structure will pave the path for the fabrication of low-cost, environment friendly and stable perovskite solar cell.","PeriodicalId":350012,"journal":{"name":"2022 International Conference and Utility Exhibition on Energy, Environment and Climate Change (ICUE)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126087096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed MPPT consists of a Single-Ended Primary-Inductor Converter (SEPIC) converter and Grey Wolf Optimizer (GWO) algorithm. SEPIC converter is used to provide lower ripple-power output while GWO is used to optimized the duty cycle of the SEPIC converter.

This paper presents a methodological approach for integrated building energy modeling and analysis of the impacts of energy conservation measures (ECMs) and energy-related CO2 emissions in urban areas. To accomplish this goal, the proposed methodology follows four steps: (1) developing a building stock model for urban databases using a geographic information system (GIS) and QGIS software; (2) creating a detailed archetype-based building stock model using OpenStudio and EnergyPlus; (3) carrying out a scenario analysis of possible ECMs and pathways to achieve carbon neutrality; and (4) analyzing energy savings and energy-related CO2 emissions. The developed methodology was applied to a tourism urban area, using Pattaya city as a case study. Based on the GIS building model, six archetypes were identified from all residential buildings, including hotels located in the study area. Prototypes of representative building energy models were simulated for a reference case with four ECMs. The results indicated that the building stock in the reference case used 497,669.05 TJ annually and emitted 80,470.32 ktC02eq. Of the four ECMs, a change to double glazing with low-E coating gave the highest energy savings and reductions in CO2 emissions. This measure led to energy savings of 9,342.82 TJ and emission reductions of 356.23 ktC02eq compared to the reference case. Local governments and stakeholders can benefit from the proposed methodological approach for decision making related to energy and carbon neutrality pathways.","PeriodicalId":350012,"journal":{"name":"2022 International Conference and Utility Exhibition on Energy, Environment and Climate Change (ICUE)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133140159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, this study aims to determine the different perceptions, barriers, and driving parameters of local households to adapt to climate change. A total of 350 respondents in local regions were considered for the survey. The Multi-Logis Regression (MLS) model was applied to determine the driving parameters affecting the choice methods. A majority of farm households realized the huge impacts of climate change and actively planned to adapt. The findings also indicated that farm households applied widening solutions (11 methods) to adapt to climate change; importantly, production diversification was reported as the most important solution. While there was still a minor percentage that did not apply, at least a choice (6%). The results from the MLS model indicated that the adaptation process is driven positively and significantly by several factors, including age of the household head, gender of the household head, typology of household, and perception of climate change. Based on the research findings, a number of short- and long-term recommendations were developed to improve the efficiency of climate change adaptation and reduce the negative impacts of climate change at farm level.","PeriodicalId":350012,"journal":{"name":"2022 International Conference and Utility Exhibition on Energy, Environment and Climate Change (ICUE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133185444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Paris agreement conferences aim to delineate the climate change problem and strengthen the collaboration between the potential countries and developing countries which facing more challenges in terms of financial resource and socioeconomic. The agreement requires each country to implement their domestic climate policy which covers economic, social, and political issues in responding to climate change such as low carbon emission development plans, mitigation and adaptation measures, and climate resilience development. These climate actions are delivered as Nationally Determined Contributions (NDCs) which is a long-term achieving low-emissions plan and reflect the national GHG emission reduction priorities. This research explores the NDC in Thailand context with focus on the development of infrastructure construction sector which is a significant sector contribute to economic growth of the country. Thailand's Nationally Determined Contributions implements 15 climate long-term approaches for year 2021–2030 which covers to 3 categories: Energy and Transportation, Waste Management, and Industrial Manufacture and Product Application. In Thailand, likewise other countries, energy sector is the most contributor to the largest portion of GHG emission as it is interconnected with all activities including the focus area, construction of infrastructure. This research aims to analyze relevant approaches for construction sector indicated in the NDC Roadmap on Mitigation 2021–2030, and the Guidelines for driving and evaluating which includes the mitigation and adaptation measures on climate change. The construction sector by compliance with the NDCs approaches appears to be a potentially significant factor for sustainable development and low carbon future, likewise, building climate resilience through mitigation and adaptation practices, for instance, the application of Ecosystem-Based Adaptation (EbA), the construction rating system as a guideline for measuring sustainability in both building scale and component scale. In addition, to achieve the long-term goal, the participation and collaboration have to be bonded strongly in all phases to support climate action mechanisms in both domestic and international level.","PeriodicalId":350012,"journal":{"name":"2022 International Conference and Utility Exhibition on Energy, Environment and Climate Change (ICUE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115441184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method used for the climate study is supported by the inter-sectoral model inter-comparison project (ISIMIP database). The recent ISIMIP input dataset, ISIMIP2b, outlines simulation scenarios divided into different emissions pathways (or “Representative Concentration Pathways” known as RCPs). This paper focuses on the two extreme RCPs, specifically RCP2.6 and RCP8.5, which would result in global average temperature increases of approximately 1.6 and 4.3°C respectively. Th analysis concentrates on the difference between the historic period and the end of the century (toward 2100) for the climate conditions for the future. The fuzzy logic global land suitability model has been used to calculate the suitability of the land to support growing crops as well as to investigate how the climate changing could impact this. The analysis shows that quite significant changes in hydro-generation potential can occur depending on the region: Laos and Cambodia show decrease when Myanmar shows increase in output potential between present and RCP2.5 and RCP8.5 respectively. Quite significant increases or decreases in land suitability can occur depending on the region and the crop.","PeriodicalId":350012,"journal":{"name":"2022 International Conference and Utility Exhibition on Energy, Environment and Climate Change (ICUE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124145158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, CdTe is also a direct band gap material having a direct band gap that has a favorable match with the solar spectrum. Hence, this offers high theoretical efficiencies, which significantly reduces the thickness of the absorbing layer when compared to other materials (e.g., silicon) used in TFSCs. Additionally, Cadmium (Cd) is readily available mainly as a byproduct of the mining industry. Hence, CdTe solar cells now have the lion's share of the TFSC market. However, limited availability of Tellurium (Te) is one of the major challenges hindering the development of CdTe solar cells. Therefore, it is important to design new highly efficient CdTe TFSCs with ultra-thin layers that can significantly reduce the demand on Te. One such method can be coupling plasmonic metal nanoparticles to the absorbing layer of CdTe TFSCs to improve the light absorption and current generation capacity of the solar cells. In this light, this computational study was conducted using the Finite-Difference Time-Domain (FDTD) method that used spherical plasmonic nanoparticles of various metals, e.g., silver, gold, aluminum and titanium, and of different sizes coupled to the absorbing substrate of CdTe TFSCs to investigate their effect on the opto-electronic performance of the solar cells. The results show that the opto-electronic performance of CdTe TFSCs is significantly enhanced by most of the metal nanoparticles mentioned, with silver showing the most significant enhancement. It was observed that 150 nm diameter spherical silver nanoparticles placed on the top surface of CdTe TFSCs, yields greater than 25% enhancement in the short-circuit current density (Jsc) when compared to bare CdTe TFSCs. It was also observed that the other performance parameters of CdTe TFSCs such as open-circuit voltage, fill factor, output power and efficiency also show enhancements with the presence of spherical plasmonic metal nanoparticles. It is hoped that the encouraging results of this study can inspire exciting new research to significantly improve the opto-electronic performance of CdTe TFSCs using different innovative mechanisms.","PeriodicalId":350012,"journal":{"name":"2022 International Conference and Utility Exhibition on Energy, Environment and Climate Change (ICUE)","volume":"217 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128934868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study aims to find the best practice in carbon-neutral planning for Thailand's power sector from international experiences through their communication of long-term strategy submissions. Fifteen countries are selected to be investigated and compared in their planning, specifically in the power sector. As a result, there are four key lessons from the reviewed countries. First, the decarbonization of electricity needs to be targeted by 2035 to support their carbon neutrality goal. Second, Renewable Energy (RE) needs to be set as the main power source in their power generation mix. Third, other sectors (e.g., transport, industrial and building) will be transformed by using electricity instead of fossil fuel. Forth, existing power plants with carbon capture storage (CCS) and other alternative technologies (e.g., energy storage, clean hydrogen, and smart grid) will be integrated to ensure energy security in the power system. Consequently, these key lessons will be adapted using SWOT analysis to propose Thailand's power sector pathway for achieving carbon neutrality by 2050.","PeriodicalId":350012,"journal":{"name":"2022 International Conference and Utility Exhibition on Energy, Environment and Climate Change (ICUE)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126533012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
