The valorization biogas using the dry reforming of methane was evaluated. For this purpose, Ni2Mg4Al2 catalyst was synthesized using co-precipitation method, calcined and reduced at 800 °C and analyzed using physico-chemical techniques. The efficiency of the sample in the dry reforming was evaluated in a series of 12 h stability tests at 750 °C in the presence of synthetic, clean, and unrefined biogas. The obtained results show a stable activity in all conditions except in the presence of unrefined biogas. Even though the initial conversion rate was above 70%, the activity quickly decreased, and the catalyst was completely deactivated after 2 h on stream. Using the thermal analysis of the used samples, no carbon was detected for this catalyst, proving that it was not the cause of the deactivation. However, XRD results showed a lack of reduced Ni species in this catalyst, suggesting that the deactivation may be due to the reoxidation of the active phase. In further studies, it would be interesting to work on developing a catalytic material resistant to oxidation in order to extend its shelf-life.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"337 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":"131987656","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 addresses this research gap by conducting a residential electricity consumption survey within 387 households in the city of Ouagadougou, Burkina Faso. To the authors' knowledge this is the first large-scale, city-wide household electricity study undertaken in Burkina Faso. Information on the households' socio-demographic characteristics, behaviours, and patterns of electricity use were collected to provide insights into the actual city-scale residential electricity use. Findings showed that households use, on average, 2395 kWh/year. Cooling accounts for 39.9% of the total electricity use, followed by cooking/food preserving (22.7%) and information-communication-entertainment (19.1%) activities. The study’s findings could be used by researchers, energy actors and households to better understand actual electricity use patterns in a city and country where a paucity of data currently exists as well as to identify ways to modify consumption patterns to reduce power outages and improve the living conditions of households.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"1 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":"115127825","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}

In recent years, new ideas have continuously emerged on this subject. Microchannels and microcavities have proven better heat transfer efficiency [1-3]. The present study aims to analyze the magnetohydrodynamics (MHD) heat transfer enhancement and entropy generation in a micro open tall cavity filled with nanoliquid under the effects of uniform magnetic field and bottom sinusoidal heating in the slip flow regime. A mesoscopic numerical analysis based on the SRT-BGK lattice Boltzmann numerical method (LBM) is used to resolve the governing equations with boundary conditions special treatment. The slip velocity and the temperature jump conditions are used to incorporate the micro aspect. The flow pattern, heat transfer characteristics and the irreversibility pattern are studied dependently on various dimensionless independent monitoring parameters in a set of ranges, namely: Rayleigh number (Ra) (102-104), Knudsen number (Kn) (0-0.1) and Hartmann number (Ha) (0-80), nanosuspensions volume fraction Vf (0-0.04%) as well as the magnitude A (0-1) and wave length parameter f of the sinusoidal heating function T(x) =A sin(fx/L), 1≤f=2πL/λ≤9 and λ is the signal wavelength.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"5 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":"117189809","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, researchers conduct techno-economic assessments. Frequently, these employ many input parameters, several of which are both difficult to estimate and subject to unpredictable changes of the economy. The utility of techno-economic studies is therefore reduced for readers, since sensitivity of the results to changes of the input parameters remains hidden in the model. This paper proposes a generalized method and exercises it with a model for renewable energy driven desalination. The method is simple to apply but could make techno-economic assessments more informative and transparent. For the evaluated model, the main financial indicator is chosen to be the margin of levelized cost of water for renewable energy driven desalination over a reference process. Only six parameters change the main indicator by more than 1.5% given an absolute change of the input of 0.05. The final graph shows, that even in the worst-case scenario created in a combined parametric study, wind driven desalination is cost competitive for electricity prices greater than 6 cent per kWh. Desalination driven by photovoltaic produces water cheaper than the reference process for most scenarios but may be inferior at low electricity prices.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"34 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":"131366505","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}

Nevertheless, the conventional transformer (CT), which is the most important component of the distribution system, cannot fulfill the SDG requirement. In this regard, the modular smart transformer (ST) has emerged as a promising alternative to CT in the SDG. The structure of this transformer includes power conversion stages and multiple DC buses on the Medium Voltage (MV) and Low Voltage (LV) sides. This paper proposes an ST model based on a five-level Cascaded H-Bridge (CHB) rectifier in the MV AC-DC power conversion stage, six dual active bridge converters in the high-frequency DC-DC power conversion stage, a three-phase four-leg inverter in the LV DC-AC power conversion stage, and six DC buses on the MV and LV side, for SDG applications. The use of the four-leg inverter in the ST model enables to improve the quality of the grid voltage, minimize the neutral current and provide power supply for a three-phase or single-phase load. Moreover, a voltage balance control for the CHB rectifier is presented in this paper to eliminate the voltage unbalance problems in DC buses and improve the ST performance. Finally, the simulation results verify the good performance of the proposed control system.","PeriodicalId":115939,"journal":{"name":"2022 13th International Renewable Energy Congress (IREC)","volume":"38 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":"121699092","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}
