However, the development of rechargeable lithium metal batteries is hampered by the issues such as low Coulombic efficiency, unstable growth of the solid-electrolyte interphase (SEI) and dendrites. Herein, a polymeric inorganic composite coatings (PICC) on the Celgard separator has been developed to regulate the Li-ion transport during charge/discharge of the battery. The PICC is a combination of poly(vinylidene fluoride) (PVDF) and Li6.03La3ZrNb0.25Al0.24O12 (LLZO). In the carbonate-based electrolyte, the cycle life of Li ‖ Cu batteries with coating (PVDF:LLZO=1:2) increases from 30 cycles for uncoated batteries to 120 cycles and a high Coulomb Efficiency of 96% is achieved. Moreover, the Li‖NCM811 batteries using the PICC exhibit decent rate and cycling performance. After 100 cycles, the capacity retention of 94% at 0.2C is obtained, and the specific capacity is maintained above 191 mAh/g.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116344412","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}

This study aims at deploying a general ABM simulation framework to facilitate electricity exchange and demonstrate the functionality of blockchain. The simulation involved a Transactive Energy Distributed Energy Resource in a block chain dependent robust multi-agent structure. The LEM proposal based on blockchain uses auction system to balance supply and demand. Prediction error impacts on market outcomes were reduced by the LTSM model. The prediction procedure works on blockchain based LEM with adjusted prediction procedure. In ten real-world household power consumption datasets, the proposed hybrid deep learning neural network outperforms the state-of-the-art methods. To complement the proposed framework for actual application use, we additionally offer a k-step power consumption forecasting technique. This research offers a scalable environment for analyzing an energy blockchain from the perspective of Qatari society, finance, and technology.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131231332","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}

This study investigates the causes of the recent fall in SHS for lighting users in Rwanda based on adaptability and size in the choice to purchase SHS. In this article, adoption and sizing decisions that affect the choice to buy a home solar system are attempted to be quantified. Multivariate Probit (MVP) model are used to analyze the data. The same non-income factors— kerosene, rechargeable batteries, phone charging time, the number of children, and indoor pollution are presented in this research as the primary criteria for adjusting SHS and determining size. The study found that the level of kerosene use is found to have a substantial impact on the decision to begin using the light of SHS. It’s also found that non-income factors play a big role in the spread of SHS in rural Rwanda. The study concludes that household income alone is insufficient to estimate the latent demand for SHS in Rwanda.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124434963","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}

Fenestration is among the most important variables impacting residential building indoor temperatures. So, it is crucial to use the most optimal energy-efficient window glazing in buildings to reduce energy consumption and at the same time provide visual daylight comfort and thermal comfort. Many studies have focused on the improvement of building energy efficiency focusing on the building envelope or the heating, ventilation, and cooling systems. But just a few studies have focused on studying the effect of glazing on building energy consumption. Thus, this paper aims to study the influence of different glazing types on the building’s heating and cooling energy consumption. A real case study building located under a semi-arid climate was used. The building energy model has been conducted using the OpenStudio simulation engine. Building indoor temperature was calibrated using ASHRAE’s statistical indices. Then a comparative analysis was conducted using seven different types of windows including single, double, and triple glazing filled with air and argon. Tripleglazed and double-glazed windows with argon space offer 37% and 32% of annual energy savings. It should be stressed that the methodology developed in this paper could be useful for further studies to improve building energy efficiency using optimal window glazing.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125995420","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}

Then, the advantages of this new system compared to a classical one are shown. Finally, the developed wind pumping system and the standard mechanical wind pumping system were simulated in order to prove that the proposed system has the best results in terms of power efficiency and stored water.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114977767","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}
