The phase change hysteresis (PCH) phenomenon is particularly prominent since the phase transition of PCM mixture non-isothermal. In this paper, a paraffin-based nanocomposite PCM were prepared, the multiwalled carbon nanotubes (MWCNTs) and sodium dodecyl benzene sulfonate (SDBS) were comprised for the enhancement of thermal conductivity and suspension stability. The PA/MWCNTs/SDBS composite PCM exhibited excellent chemical compatibility, better thermal storage capacity, high thermal charging and discharging efficiency, and preferable thermal and cyclic stability through a series of characterization. Furthermore, the differential scanning calorimetry (DSC) was performed to investigate the association of temperature range, temperature changing rate, and sample mass on hysteresis degree. Besides, the causes of PCH were interpretated from the respective of energy storage, temperature delay, thermal resistance of PCMs, crystallinity, and interfacial free energy. The results showed that PCH phenomenon is controllable, thereby improving the energy utilization efficiency of PCMs. Namely, the prepared PA/MWCNTs/SDBS composite PCM with suitable phase transition temperature of 5.5 °C, high latent heat of 222.7 J g -1 , and thermal conductivity of 0.3727 W m -1 K -1 , possesses enormous potential in large-scale applications.","PeriodicalId":433656,"journal":{"name":"MatSciRN: Energy Storage (Topic)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123038441","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}

However, the complexity of synthesis and safety issues caused by harmful dopant precursors must be overcome. Herein, a one-step plasma-in-liquid process is adopted to synthesize N and S co-doped carbon-based anode material (NS/C) for SBBs. NS/C exhibits a large specific surface area (476.8 m2 g-1) and abundant active sites on its surface owing to its void structure. Owing to the advantages of this structure, NS/C evidently caused a co-intercalation reaction in an ether-based electrolyte while avoiding solid electrolyte interface (SEI) layer formation on the anode surface. Transmission electron microscopy, electrochemical impedance spectroscopy, cyclic voltammetry, and the Brunauer–Emmett–Teller method with a novel analysis method using terahertz waves are employed to prove that no SEI formed on the anode surface. When the anode is applied to a sodium-ion half-cell, NS/C exhibited a remarkable cycling life of 35,000 cycles at an ultrahigh current density of 100 A g-1 with high reversible capacity of > 72 mAh g-1. Furthermore, NS/C shows outstanding electrochemical performance for a seawater battery anode, with a cycling life of more than 1,500 at the first attempted current density of 10 A g-1.","PeriodicalId":433656,"journal":{"name":"MatSciRN: Energy Storage (Topic)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124425068","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}

Baxter","doi":"10.2139/ssrn.3819906","DOIUrl":"https://doi.org/10.2139/ssrn.3819906","url":null,"abstract":"The Cryogenic Carbon Capture™ (CCC) process separates CO2 from light gases in essentially any continuous process. CCC cools the gases to the frost or desublimation point of CO2 (−100 to −135 °C), separates and pressurizes the solids, and warms all streams to produce a CO2-depleted stream at ambient pressure and a pure (99+%) pressurized liquid CO2 stream typically to about 150 bar, both at ambient temperature. The process also recovers all gas moisture and most gas impurities less volatile than CO2 (NOx, SOx, Hg, PM, UHC, CCC, etc.) in separable streams. CCC nearly eliminates refrigeration energy for sensible temperature changes through heat integration. CCC does require energy to change the CO2 phase from a mixed vapor to a pressurized fluid, which represents the minimum energy required of any process for this separation. CCC uses additional energy for turbomachinery inefficiencies, heat losses, moisture removal and overall process pressure drop. Aside from these real-world energy demands, CCC operates near the minimum energy required to perform this gas separation by minimizing stream recycling. CCC compresses CO2 as a liquid, which is one of several reasons it costs about about half as much and consumes about half as much energy as an amine process when using flue gases with about 15% CO2. The process also has several major additional advantages, including (a) it is a bolt-on retrofit technology that does not need steam or any modification of existing equipment, (b) it recovers water and nearly all pollutants in addition to CO2 from the flue gas, (c) it enables highly efficient and cost effective energy storage at grid scale and on time scales of minutes, (d) it enables NG storage if the energy storage option is used, and (d) it has a small footprint and is minimally disruptive to existing plants, requiring only electrical power and a gas source to operate. \u0000Sustainable Energy Solutions (SES) has scaled this technology through several levels, the largest of which captures nominally 1 tonne of CO2/day and is called the skid system. Skid system field tests include utility-scale power plants, cement plants, heating plants, and other utility or industrial sites that burn natural gas, biomass, coal, shredded tires, municipal waste, and combinations of these fuels. These field tests produced 95-99% CO2 capture with CO2 purities of 99+% and initial CO2 contents that range from 4 to 28%. SES currently seeks to scale the system to merchant scale (10-80 tonnes of CO2 per day). In the process of doing so, SES has demonstrated the potential for CCC to contribute to energy storage and direct air capture in innovative and cost-effective ways. \u0000This presentation discusses the overall process and highlights results from field and in-house tests. These include (a) measured CO2 capture rates and operating conditions from in-house and field tests, and (b) predicted utility-scale costs and energy demands.

The project team studied the storage capacity of the target formations, estimated the CO2 plume size, performed a sensitivity analysis to examine the influence of reservoir and fluid properties, and tested the impact of active plume management—a process that includes extracting water from down-dip water production wells and re-injecting it through up-dip water injection wells within the storage formation—on CO2 plume migration and its extent.<br><br>The ECO2S site appears to be capable of storing captured CO2 emissions from multiple Southern Company operated power sources, which together emit 22.5 million metric tons per year (675 million metric tons over 30 years). To investigate field development strategies for large volume CO2 injection and storage at ECO2S, the project team developed a base model using the latest geological interpretation. Thirty years of CO2 injection is simulated through seven injection pads with each pad hosting three injection wells, positioned in the center of the potential storage site, followed by 30 years of CO2 plume monitoring. The simulation results show that the 675 million metric tons of CO2 can be injected into the storage formations, safely and securely. The largest CO2 plume, which occurs in the shallowest reservoir, covers a 202-square kilometer area. Active plume management shows a small impact on controlling the plume size and its migration due to extremely high vertical permeability minimizing the impact of the water curtain.<br><br>Project ECO2S is part of the CarbonSAFE Program and is financially supported by the USDOE-NETL and Mississippi Power Company.

One of the problems of modern electrical engineering is to ensure the reliability of the operation of capacitors at electric field strengths exceeding I50-200MV. In the domestic and foreign capacitor industry, for heavy pulse modes, castor oil (CO) is used as a liquid impregnation. The development of a method for producing a substitute for natural castor oil, which is a universal impregnating liquid in capacitors, is an urgent problem in the electrical industry. Thus, we have developed a method for the production of acetoxymethyl-w.hexyl-o-xylene, the electrophysical properties of which make it possible to use it as an environmentally friendly and promising substitute for natural castor oil. However, there was a problem of stabilization, since compounds of the ester type have (as impregnating liquids in capacitors) a disadvantage, which consists in their sensitivity to light hydrolysis and atmospheric effects. Ester exhibits high stability with respect to air up to 200 °С, therefore, inhibition by the addition of antioxidants is required is not new. \u0000In this work developed the basic electrophysical properties of the ester-acetoxymethyl-secondary hexyl-o-xyleole; methods for its purification and stabilization.

MALDI is suitable for characterization of organic and polymer molecules but is inconvenient to couple with chromatography methods. This study employs on-electrode chromatography which utilizes the electrode itself as stationary phase for fractionating the molecules on the electrode surfaces, successfully introducing chromatography separation approaches for MALDI. With on-electrode chromatography, SEI components were characterized by MALDI directly on the electrodes.

But Delhi has a river Yamuna. The total length of River Yamuna in the NCR region is 48 km, of which 22 km lies in main capital and the rest falls in the National Capital Region. So, a solar power plant can be established over the river by building pillars in the river and making a structure over these pillars and then solar panels can be installed over these structures. The flow of the river can be also maintained in this project. The whole 22 km open area can be used to set up a solar power plant, and this will produce at least 5 Megawatt electricity. This is the clean energy so it will reduce pollution and will fulfill the energy need of this city, this area is already waste (can’t be utilized for other purposes) and today, India has the technical capability to establish this kind of project.","PeriodicalId":433656,"journal":{"name":"MatSciRN: Energy Storage (Topic)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130562880","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}

To avoid the multiple conversion and more reliable the proposed hybrid microgrid is designed by taking diesel generators, Photovoltaic cell, induction generators and battery bank.

This paper proposes a standalone hybrid generation system, fed by induction generator which is run with a battery banks, solar power, and storage battery. Hybrid microgrid is an excellent solution for electrification of remote rural areas where the grid extension is very difficult and not economical. Practically it has been seen that most of the isolated grid is powered by the diesel generation system, such systems has several problems like high cost fuel with extra transportation cost and making more pollution to the environment .To make pollution free environment ,an eco-friendly hybrid microgrid system has designed. It maintains the power quality in steady state condition. During this transient condition, the voltage and frequency of the microgrid may change rapidly due to low inertia present in microgrid.

For such a system, an optimization problem is formulated with the objective of maximizing the total data rate and conserving the source and relays transmission energy, where any extra energy saved in the current transmission cycle can be used in the next cycle. It turns out that the optimal solutions for this problem can be either found in a closed form or through one-dimensional searches, depending on the scenario.
