Abstract

Recently, the growing demand for a renewable and sustainable fuel alternative is contingent on fuel cell technologies. Even though it is regarded as an environmentally sustainable method of generating fuel for immediate concerns, it must be enhanced to make it extraordinarily affordable, and environmentally sustainable. Hydrogen (H2) synthesis by electrochemical water splitting (ECWS) is considered one of the foremost potential prospective methods for renewable energy output and H2 society implementation. Existing massive H2 output is mostly reliant on the steaming reformation of carbon fuels that yield CO2 together with H2 and is a finite resource. ECWS is a viable, efficient, and contamination‐free method for H2 evolution. Consequently, developing reliable and cost‐effective technology for ECWS was a top priority for scientists around the globe. Utilizing renewable technologies to decrease total fuel utilization is crucial for H2 evolution. Capturing and transforming the fuel from the ambient through various renewable solutions for water splitting (WS) could effectively reduce the need for additional electricity. ECWS is among the foremost potential prospective methods for renewable energy output and the achievement of a H2‐based economy. For the overall water splitting (OWS), several transition‐metal‐based polyfunctional metal catalysts for both cathode and anode have been synthesized. Furthermore, the essential to the widespread adoption of such technology is the development of reduced‐price, super functional electrocatalysts to substitute those, depending on metals. Many metal‐premised electrocatalysts for both the anode and cathode have been designed for the WS process. The attributes of H2 and oxygen (O2) dynamics interactions on the electrodes of water electrolysis cells and the fundamental techniques for evaluating the achievement of electrocatalysts are outlined in this paper. Special emphasis is paid to their fabrication, electrocatalytic performance, durability, and measures for enhancing their efficiency. In addition, prospective ideas on metal‐based WS electrocatalysts based on existing problems are presented. It is anticipated that this review will offer a straight direction toward the engineering and construction of novel polyfunctional electrocatalysts encompassing superior efficiency in a suitable WS technique.

Abstract

The increasing demand for searching highly efficient and robust technologies in the context of sustainable energy production totally rely onto the cost‐effective energy efficient production technologies. Solar power technology in this regard will perceived to be extensively employed in a variety of ways in the future ahead, in terms of the combustion of petroleum‐based pollutants, CO2 reduction, heterogeneous photocatalysis, as well as the formation of unlimited and sustainable hydrogen gas production. Semiconductor‐based photocatalysis is regarded as potentially sustainable solution in this context. g‐C3N4 is classified as non‐metallic semiconductor to overcome this energy demand and enviromental challenges, because of its superior electronic configuration, which has a median band energy of around 2.7 eV, strong photocatalytic stability, and higher light performance. The photocatalytic performance of g‐C3N4 is perceived to be inadequate, owing to its small surface area along with high rate of charge recombination. However, various synthetic strategies were applied in order to incorporate g‐C3N4 with different guest materials to increase photocatalytic performance. After these fabrication approaches, the photocatalytic activity was enhanced owing to generation of photoinduced electrons and holes, by improving light absorption ability, and boosting surface area, which provides more space for photocatalytic reaction. In this review, various metals, non‐metals, metals oxide, sulfides, and ferrites have been integrated with g‐C3N4 to form mono, bimetallic, heterojunction, Z‐scheme, and S‐scheme‐based materials for boosting performance. Also, different varieties of g‐C3N4 were utilized for different aspects of photocatalytic application i. e., water reduction, water oxidation, CO2 reduction, and photodegradation of dye pollutants, etc. As a consequence, we have assembled a summary of the latest g‐C3N4 based materials, their uses in solar energy adaption, and proper management of the environment. This research will further well explain the detail of the mechanism of all these photocatalytic processes for the next steps, as well as the age number of new insights in order to overcome the current challenges.

Abstract

This work is devoted to study the comparison of the conduction mechanism in bare barium hexaferrite (BaFe12O19) nanoparticles and tetraethyl orthosilicate-coated (SiO2)x/BaFe12O19 (x = 5, 10, 15 and 20 wt. %) nanoparticles. The modified sol–gel method was adopted for the synthesis of these nanoparticles. The structures, morphologies, elemental composition, vibrational modes, and dielectric properties of these nanoparticles were studied by x-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, Fourier transform infrared spectroscopy, and dielectric measurements, respectively. The crystallite size and particle size of BaFe12O19 nanoparticles decreased with SiO2 coatings, which can be attributed to the confinement of crystal growth of these nanoparticles with the coating. It was found that these (SiO2)x/BaFe12O19 nanoparticles have a uniform spherical shape, are non-agglomerated, and have a narrow particle size distribution. At room temperature, these (SiO2)x/BaFe12O19 nanoparticles showed distinctive behavior with varying frequency and SiO2 coatings. The experimental results in this work may provide fundamental support to the research and development of materials for energy storage devices.

Abstract

Recently proposed ambitious targets for Ireland and Northern Ireland will require that the power system of Ireland and Northern Ireland is capable of operating with significantly high levels of non-synchronous variable renewable generation. Ensuring such high levels of RES-E on the Ireland and Northern Ireland power system will require operation of the system with instantaneous penetration of non-synchronous renewables in excess of 90%. Such high levels of non-synchronous generation in an island system are unprecedented and pose considerable technical challenges. Transitioning from a level of instantaneous non-synchronous penetration of renewables of 75% to more than 90% will exacerbate existing technical challenges and may reveal new, as of yet, unaccounted-for-scarcities. The focus of this paper is on a sample of the detailed analysis for the Ireland and Northern Ireland power system from Work Package 2 of the Horizon 2020 funded EU-SysFlex project.

40. Load curtailment minimization by optimal placement of Unified Power Flow Controller

Author

Singh, J. G., Qazi, H. W., Ghandhari, Mehrdad, Singh, J. G., Qazi, H. W., and Ghandhari, Mehrdad

Abstract

In this paper, a new sensitivity-based approach is proposed to minimize the load curtailment by optimal placement of series controller of the Unified Power Flow Controller (UPFC) in the power system. The proposed sensitivity factors are derived in terms of change in load curtailment with respect to change in UPFC series control parameters. The effectiveness of the proposed method has been investigated by formulating an optimal power flow problem with an objective to minimize the load curtailment. Results have been obtained on IEEE 14-bus and IEEE 30-bus systems. It has been shown that required load curtailment drastically reduced with placement of UPFC and could be effective in various operating conditions of power system. With this technique, a large amount of power curtailment could be avoided, hence, saved from revenue loss, social disobedience, and customer service interruption., QC 20170109

Abstract

Recent years have seen the interest in demand response increase, in academia and in industry, for both large scale demands and aggregated domestic demands. A number of power systems have established demand response programs in energy, ancillary services and capacity markets, while many are currently undertaking system specific customizations. One of the key reasons for the burgeoning interest in demand response lies in its ability to enhance variable renewable penetration levels, through the provision of flexibility, wind/solar curtailment reduction and other system ancillary services. This paper will review and evaluate various demand response studies, projects and programs from different countries, examining the synergies with renewables integration, also identify some of the main barriers which exist to the deployment of such demand response at greater scale.
