These properties make the PCMs good candidates for thermal batteries and other thermal energy storage applications in the building sector. However, PEG leakage is observed at elevated temperatures, and due to the hygroscopic nature of PEG, moisture ingress is also observed, which can have a significant effect on performance and durability. Thus, we have developed hydrophobic coatings to prevent PEG leakage and mitigate moisture ingress. The selected approach involves a secondary sol-gel process during which a thin layer formulated with hydrophobic precursors is deposited onto the surface of the PCM samples. Several coating formulations have been investigated, including formulations composed of tetraethyl orthosilicate (TEOS), diethoxy(dimethyl)silane (DEDMS), triethoxymethylsilane (TEMS), and n-octyltriethoxysilane (OTES). We find that this is effective at increasing hydrophobicity of the PCM substrates. It also decreases substrate leakage.","PeriodicalId":384147,"journal":{"name":"ASME 2022 16th International Conference on Energy Sustainability","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128283784","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 order to reach the final goal, carbon neutral, it requires people to reduce the fossil fuel energy consumption and carbon dioxide emission. Distributed energy systems (DES) have received an increasing attention from the researchers and governments. However, despite the previous DES studies on various distributed energy resources and systems from different aspects, the integration and design optimization issues have not been investigated sufficiently. In this paper, a multi-objective optimization in terms of life cycle environmental and economic impacts is proposed to obtain an optimal design of distributed energy systems for different building types in various climate regions. Several typical distributed energy technologies are considered in this paper including combined heat and power system (CHP), solar photovoltaic (PV), solar thermal collector (STC), wind turbine (WT), as well as battery energy storage (BES) and thermal energy storage (TES). The building types under investigation are hospital, large office, and large hotel. The proposed multi-objective optimization is applied to determine the best combination of distributed energy technologies as well as the system size for different locations building types.

In this paper, the conventional process of monoethanolamine (MEA)-based post-combustion CO2 capturing system is modified to reduce the process energy consumption for flexible and efficient integration to fossil-fueled power plants. Considering a flue gas stream similar to coal-fired power plants, rigorous rate-based modeling of the MEA-based CO2 capture system is performed in Aspen Plus using the electrolyte nonrandom two-liquid thermodynamic package (ENRTL-RK). Afterward, three main process modifications, including lean vapor compression, rich solvent preheating, and rich solvent splitting, are investigated in both full and partial load conditions to assess their impacts on the process efficiency and energy consumption. The results demonstrate that the lean vapor compression and the rich solvent preheating modifications significantly reduce the process energy consumption by 13.5% and 8.4%, respectively. However, the addition of extra equipment such as compressors, flash vessels, and heat exchangers increase the capital and operational costs of the capture plant. Also, rich solvent splitting, which requires minor modifications in process equipment, reduces the energy consumption by 5.4%. Moreover, it is observed that the operating conditions for CO2 capture vary significantly between partial and full load conditions, and considerable reduction in energy consumption and improvement in process flexibility can be achieved at optimal process conditions.","PeriodicalId":384147,"journal":{"name":"ASME 2022 16th International Conference on Energy Sustainability","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116358929","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}

Since the energy consumption and economy of membrane-based carbon capture systems (CCSs) are critical for their large-scale deployments, optimal design and operation of such systems are the primary aims of this study. To achieve these research goals, a numerical model based on the solution-diffusion mechanism for the multicomponent gas separation process with a hollow-fiber membrane module is developed using Aspen Custom Modeler. The model is employed to investigate the effects of important operating and design parameters. Multi-objective process optimization is then performed by linking Aspen Plus and MATLAB and using an evolutionary technique to determine the optimal operating and design conditions. Our results show that by increasing the CO2 concentration in the feed gas, the CO2 capture cost significantly decreases and CO2 removal improves, although the process energy requirement slightly increases. The best achievable tradeoffs between objective functions are generated and analyzed, which substantiate the significant potential for improving the sustainability of the process. The results show that at optimum design and operating conditions, CO2 capture cost and energy consumption of the process could be as low as 13.1 $/tCO2 and 61 MW, respectively. The results of this study provide valuable insights into membrane separation and can be used by decision-makers to achieve the optimal performance of the process for commercial development and deployment of the technology.","PeriodicalId":384147,"journal":{"name":"ASME 2022 16th International Conference on Energy Sustainability","volume":"72 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132411882","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}

Optimization of the performance parameters was also carried out using multi-criteria decision-making methods (WASPA S and MOORA) for the first time. The RSM and ANN were employed in predicting the performance parameters such as CPKB fuel blends (FB) (0–20 vol.%), engine load (EL) (0–50%), and engine speed (ES) (1000–2000 rpm) on the performance indicators viz. brake torque (BT), brake power (BP), brake specific fuel consumption (BSFC), brake thermal efficiency (BTE).

For comparison, the team also performed roasting from a traditional propane gas heating source, monitoring the volume of propane being consumed over time to assess carbon emissions that were abated using CSP. Results found that roasting peppers with CSP facilitated approximately 26 MJ of energy that abated approximately 0.122 kg CO2/kg chile for a 10 kg bag.

The purpose of this analysis was to determine whether or not heat pump technology has matured to the point that a solar PV system paired with a heat pump could outperform a traditional solar thermal flat plate collector system. To this end, two systems with identical panel footprints of 7.6 m2 (82 ft2) were modelled and analyzed at four different locations being Los Angeles CA, Phoenix AZ, Seattle WA, and Denver CO. The expected energy production and Levelized Cost of Energy (LCOE) for both systems at these locations were determined. The solar fraction for the solar thermal collector systems and PV heat pump systems at the four locations studied were found to be f = 0.44 and f = 0.99 in Los Angeles, f = 0.44 and f = 1.00 in Phoenix, f = 0.21 and f = 0.62 in Seattle, and f = 0.34 and f = 0.90 in Denver. As such, it is evident that the solar PV heat pump systems produced more thermal energy than the solar thermal collectors at all locations tested. The LCOE for the solar thermal collector systems and solar PV heat pump systems at each location were found to be 48.42 ¢/kWh and 36.57 ¢/kWh at Los Angeles, 55.37 ¢/kWh and 36.13 ¢/kWh at Phoenix, 81.47 ¢/kWh and 97.29 ¢/kWh at Seattle, and 52.27 ¢/kWh and 67.50 ¢/kWh at Denver. From these values, it can be seen that the solar PV heat pump systems have a lower LCOE in the warmer climates where ground source heat pumps are not needed but have slightly higher LCOE values in cooler climates where they are. As such, this study has found that solar PV heat pump systems have matured enough to outperform solar thermal flat plate collectors in most situations.","PeriodicalId":384147,"journal":{"name":"ASME 2022 16th International Conference on Energy Sustainability","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122204882","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}
