Abstract:
AbstractSemiconductors and the associated methodologies applied to electrochemistry have recently grown as an emerging field in energy materials and technologies. For example, semiconductor membranes and heterostructure fuel cells are new technological trend, which differ from the traditional fuel cell electrochemistry principle employing three basic functional components: anode, electrolyte, and cathode. The electrolyte is key to the device performance by providing an ionic charge flow pathway between the anode and cathode while preventing electron passage. In contrast, semiconductors and derived heterostructures with electron (hole) conducting materials have demonstrated to be much better ionic conductors than the conventional ionic electrolytes. The energy band structure and alignment, band bending and built-in electric field are all important elements in this context to realize the necessary fuel cell functionalities. This review further extends to semiconductor-based electrochemical energy conversion and storage, describing their fundamentals and working principles, with the intention of advancing the understanding of the roles of semiconductors and energy bands in electrochemical devices for energy conversion and storage, as well as applications to meet emerging demands widely involved in energy applications, such as photocatalysis/water splitting devices, batteries and solar cells. This review provides new ideas and new solutions to problems beyond the conventional electrochemistry and presents new interdisciplinary approaches to develop clean energy conversion and storage technologies.

Abstract:
Thermosalient compounds, colloquially known as "jumping crystals", are promising materials for fabrication of actuators that are also being considered as materials for clean energy conversion because they are capable of direct conversion of thermal energy into mechanical motion. During heating and/or cooling, these materials undergo rapid phase transitions accompanied by large and anisotropic change in their unit-cell dimensions at relatively small volume change, causing the crystals to jump up to height of several centimeters. Although the list of about a dozen reported thermosalient materials has been expanded recently, this extraordinary phenomenon remains poorly understood. The main practical burden with the analysis of these crystals is their propensity to disintegrate during the transition. By using a combination of structural, microscopic, spectroscopic, and thermoanalytical techniques, we have investigated the thermosalient effect in a prototypal example of a thermosalient solid, the anticholinergic agent oxitropium bromide, and we proposed the mechanism responsible for the effect. We found that heating/cooling over the phase transition causes conformational changes in the oxitropium cation, which are related to increased separation between the ion pairs in the lattice. On heating, this change triggers rapid anisotropic expansion by 4% of the unit cell, whereby the b axis increases by 11% and the c axis decreases by 7%. The phase transition is reversible, and shows a thermal hysteresis of approximately 20 K. Additional interesting observations were that the high-temperature phase of this material can also be obtained by short exposure of the room temperature phase to UV light or with grinding.

Abstract:
The applications of electrochemical technology in environmental treatment, materials recycling, and clean synthesis are briefly reviewed. The diversity of these applications is shown by the number of industrial sectors involved. The scale of operation ranges from microelectrodes to large industrial cell rooms. The features of electrochemical processes are summarized. Available and developing electrode designs are considered and illustrated by examples including the regeneration of chromic acid electroplating baths, metal ion removal by porous, 3-dimensional cathodes, rotating cylinder electrodes (RCEs), and a reticulated vitreous carbon (RVC) RCE. The use of performance indicators based on mass transport, electrode area, and power consumption is emphasized. Electrochemical reactors for energy conversion are considered, with an emphasis on load-leveling and proton-exchange membrane (PEM) (hydrogen­oxygen) fuel cells. Ion-exchange membranes play an essential role in such reactors, and the variation of electrical resistance vs. membrane thickness is described for a series of extruded, Nafion® 1100 EW materials. The characterization of high-surface-area, platinized Nafion surfaces is also considered. The development of modular, filter-press cells as redox flow cells in electrical load-leveling applications is concisely described. Trends in electrode, membrane, and reactor design are highlighted, and the challenges for the development of improved reactors for environmental treatment are noted.

Abstract:
As a fundamental infrastructure of energy supply for future society, energy Internet (EI) can achieve clean energy generation, conversion, storage and consumption in a more economic and safer way. This paper demonstrates the technology principle of advanced adiabatic compressed air energy storage system (AA-CAES), as well as analysis of the technical characteristics of AA-CAES. Furthermore, we propose an overall architectural scheme of a clean energy router (CER) based on AA-CAES. The storage and mutual conversion mechanism of wind and solar power, heating, and other clean energy were designed to provide a key technological solution for the coordination and comprehensive utilization of various clean energies for the EI. Therefore, the design of the CER scheme and its efficiency were analyzed based on a thermodynamic simulation model of AA-CAES. Meanwhile, we explored the energy conversion mechanism of the CER and improved its overall efficiency. The CER based on AA-CAES proposed in this paper can provide a reference for efficient comprehensive energy utilization (CEU) (93.6%) in regions with abundant wind and solar energy sources.

Abstract:
The focus of this doctoral thesis is the atomic level design of photocatalysts and gas sensing materials. The band gap narrowing in the metal oxides for the visible-light driven photocatalyst as well as the interaction of water and gas molecules on the reactive surfaces of metal oxides and the electronic structure of kaolinite has been studied by the state-of-art calculations. Present thesis is organized into three sections. The first section discusses the possibility of converting UV active photocatalysts (such as Sr2Nb2O7, NaTaO3, SrTiO3, BiTaO4 and BiNbO4) into a visible active photocatalysts by their band gap engineering. Foreign elements doping in wide band gap semiconductors is an important strategy to reduce their band gap. Therefore, we have investigated the importance of mono- and co-anionic/cationic doping on UV active photocatalysts. The semiconductor's band edge position is calculated with respect to the water oxidation/reduction potential for various doping. Moreover, the tuning of valence and conduction band edge position is discussed on the basis of dopant's p/d orbital energy. In the second section of thesis the energetic, electronic and optical properties of TiO2, NiO and β-Si3N4 have been discussed to describe the adsorption mechanism of gas molecules at the surfaces. The dissociation of water into H+ or OH- occurs on the O-vacancy site of the (001)-surface of rutile TiO2 nanowire, which is due to the charge transfer from Ti atom to water molecule. The dissociation of water into OH- and imino (NH) groups is also observed on the β-Si3N4 (0001)-surface due to the dangling bonds of the lower coordinated N and Si surface atoms. Fixation of the SO2 molecules on the anatase TiO2 surfaces with O-deficiency have been investigated by Density Functional Theory (DFT) simulation and Fourier Transform Infrared (FTIR) spectroscopy. DFT calculations have been employed to explore the gas-sensing mechanism of NiO (100)-surface on the basis of energetic and electronic properties. In the final section the focus is to describe the optical band gap of pristine kaolinite using the hybrid functional method and GW approach. Different possible intrinsic defects in the kaolinite (001) basal surface have been studied and their effect on the electronic structure has been explained. The detailed electronic structure of natural kaolinite has been determined by the combined efforts of first principles calculations and Near Edge X-ray Absorption Fine Structure (NEXAFS).

Resumo: Um dos desenvolvimentos atuais mais significativos em sistemas energéticos está na área das células de combustível. Estes dispositivos que geram energia elétrica combinando hidrogênio (ou hidrocarbonetos) com o oxigênio do ar, apresentam-se como fortes vetores de desenvolvimento científico-tecnológico, que apontam no sentido de substituírem os motores à combustão interna na área dos transportes, assim como para gerar energia elétrica de um modo limpo e eficiente, dentro de um novo mercado, o da geração distribuída. O início das pesquisas em células de combustível ocorreu há mais de 150 anos, por William Grove, mas apenas nos últimos 15 anos, com o grande desenvolvimento na área de materiais, foi que a tecnologia em células e pilhas de combustível tomou-se bastante promissora no cenário energético mundial. É nesse contexto que surge o objetivo deste trabalho, levando em conta estudos e o desenvolvimento do Projeto Básico de uma Célula de Combustível de Eletrólito Polimérico (PEMFC), além de mostrar alguns campos de atuação que oferecem, já como dispositivos comercialmente viáveis, e servindo a sociedade. Considerou-se para tal a literatura especializada, com o projeto sendo construído a partir de software gráfico apropriado. Fezse também uma análise crítica dos dados disponíveis na literatura, anexando-se Folhas de Dados contendo especificações dos componentes da célula. Examinou-se a função de cada componente da célula, descrevendo os processos quimicos, e eletroquimicos que ocorrem neste reator assim como, as suas variáveis de projeto e de processo. Os muitos avanços alcançados no desenvolvimento tecnológico das PEMFC, principalmente no decorrer da década de 90, e a partir dela, através do esforço conjunto entre entidades governamentais e a indústria de vários países, demonstraram a viabilidade comercial desses geradores de energia, principalmente nas aplicações móveis. Assim, em um futuro determinista e imediato, as PEMFC se tornarão realidade como geradores de energia de alta eficiência e, de baixa emissão de poluentes, contribuindo para o desenvolvimento de uma sociedade mais comprometida com os impactos ambientais da geração e consumo de energia, posta a seu serviço e bem estar.

Abstract:

Electrocatalysis provides a practical solution to the increasing global energy demand while maintaining a sustainable environment. Recently nanoscale catalysts (nanoparticles, nanowires, and dealloyed surfaces) have been shown to have experimentally far superior performance than metallic crystals at sustainable energy conversion. However, the surface feature of these improved catalysts is still unknown, as the detection of the active sites directly from experiment has not been possible.

In this thesis work, we discuss using the quantum mechanics based muitiscale simulations and machine learning to understand the nature of these superior materials. We first studied jagged Pt nanowire (J-PtNW), which was shown to have performance at oxygen reduction reactions (ORR) 50 times better than Pt/C. We used multiscale simulations (reactive force field, and density functional theory) to explain this remarkably accelerated ORR activity from an atomistic perspective. Next, we looked into the irregular gold surfaces and copper surfaces (nanoparticles and dealloyed surfaces), which showed dramatically improved performance at CO2 reduction reactions (CO2RR) and CO reduction reactions (CORR). We developed the strategy to combine the reactive force field, density functional theory, and machine learning to identify the active sites responsible for their improved performance. This approach provided the possibility to understand the highly irregular and disordered surface, which is impossible with surface science experiments or with quantum mechanics. The identification of the active sites provides insights into new design concepts (alloys, NP, NW, and electrolytes such as ionic liquids) aimed at increasing product selectivity and rates simultaneously with reducing energy requirements.

This dissertation presents high-efficiency power conversion systems (PCSs) for clean energy resources. Among clean energy resources, fuel cells (FC), photovoltaic (PV) panels, and wind generators have been broadly investigated. However, these clean energy resources have the same power quality of low voltage and high current. For boosting the varied voltages of clean energy resources up to a constant DC-bus voltage for later inverter utilization, a high-step-up converter should be included into the PCS. In this dissertation, two high-efficiency high-step-up DC-DC converters are developed via employing coupled inductors. A soft-switching circuit based on the resonant theory is firstly proposed (chapter 2). Moreover, in order to improve the voltage gain and clamp the switch voltage, a three-winding coupled inductor is further adopted in the converter (chapter 3). On the other hand, for different kinds of rapidly promoted clean energy resources, a multi-input converter is developed. An active clamping circuit is employed for achieving turn-on zero-voltage-switching (ZVS) of all switches. In addition, based on the series-connected input circuits and the designed pulse-width-modulation driving signals, the conduction loss of the switches can be greatly reduced (chapter 4). For stable power supply and proper operation of clean energy resources, energy storage devices are necessary to be employed as backup powers. The demand of bidirectional power flow is considered to investigate a high-step-up bidirectional converter (chapter 5). By applying the proposed multi-input converters, the numbers of power conditioners in the PCS can be certainly reduced.

Abstract:
The development of efficient and clean energy conversion technologies is a key issue for the sustainability of energy technologies. Hydrogen is one of the best fuels for clean energy systems as its combustion product is only water. Therefore, the development of cost-effective energy conversion technologies for hydrogen generation is significant. Electrocatalytic water splitting using renewable energy is one of the best ways to obtain high-purity hydrogen and the process emits no carbon dioxide. Electrocatalytic reactions occur on the surface of electrode materials. Consequently, understanding and tuning the surface properties of electrode materials is a key aspect in the design and preparation of efficient electrocatalysts. Compared to other nanomaterials, such as nanowires or nanoparticles, the most important two features of two-dimensional (2D) nanomaterials for electrocatalysis are their tunable and uniformly exposed lattice plane and unique electronic state. This Thesis aims to synthesize and optimize novel 2D nanomaterials for the study of hydrogen-related electrocatalytic reactions. Our target reactions include the hydrogen evolution reaction (HER) and the nitrogen reduction reaction (NRR), which have great potential in hydrogen-related clean energy conversion systems. The first two chapters provide a systematic review of the development of 2D nanomaterials for electrocatalysis. The unique advances of 2D electrocatalysts are discussed based on different compositions and functions followed by specific design principles. Following this, various 2D electrocatalysts for a series of electrocatalytic processes involved in the water cycle, carbon cycle, and nitrogen cycle are discussed from their fundamental conception to their functional application. A significant emphasis is placed on various engineering strategies for 2D nanomaterials and their influence on intrinsic material performance, such as electronic properties and adsorption energetics. The first part of this Thesis focuses on the understanding of alkaline HER mechanism using 2D electrocatalyst as the platform. So far, the mechanistic understandings of alkaline HER are inapplicable to highly active nanostructured catalysts in practice. This is because most of nanostructured catalysts have complicated active sites, which cannot be identified carefully using theoretical calculations. Compared to other nanomaterials, 2D nanomaterials have uniformly exposed lattice plane which is considered as the ideal platform for the investigation of electrocatalytic reactions. Consequently, various 2D electrocatalysts with tunable active sites were synthesized and studied via advanced experimental measurements and theoretical calculations. First, a hybrid material of 2D C3N4@MoN was prepared using an interface engineering strategy. The intimate interaction of both inert C3N4 and MoN surfaces induced a highly active interface with tunable dual-active sites for alkaline HER. The enhanced activity originates from the synergy between the optimized hydrogen adsorption energy on the g-C3N4 sites and enhanced hydroxyl adsorption energy on the MoN sites. Second, atomically thin nitrogen-rich nanosheets, Mo5N6, were synthesized using a Ni-induced growth method. The 2D Mo5N6 nanosheets exhibit high HER activity and stability in natural seawater, which were superior to other TMNs and even the Pt benchmark. The superior performance of the nitrogen-rich Mo5N6 nanosheets originates from their Pt-like electronic structure and the high valence state of Mo atoms. Thirdly, a multi-faceted heteroatom-doping method (nitrogen, sulfur, and phosphorus) was applied to tune the electronic structure and HER activity of non-noble metals (Ni and Co) 2D layer directly and continuously without changing their chemical composition. The dopant-induced charge redistribution in the Ni metal 2D layer significantly influences its catalytic performance for the HER in alkaline media. The principle that bridges the dopant effect with the resultant HER activity is visualized with a volcano relationship. The second part of the thesis focuses on the exploration and synthesis of new 2D layered transition metal nitrides (TMNs) for hydrogen-related energy conversion. Firstly, the 2D layered W2N3 nanosheets with nitrogen vacancies was successfully obtained for the NRR. In this work, a new 2D layered W2N3 nanosheet was syntheiszed and the nitrogen vacancies demonstrate activity for electrochemical NRR A series of ex-situ synchrotron based characterizations show that the nitrogen vacancies in the 2D W2N3 nanosheets are stable due to the high valence state of the tungsten atoms and 2D confinement effect. Density function theory calculations suggest that the nitrogen vacancies provide an electron-deficient environment which facilitate nitrogen adsorption and lower the thermodynamic limiting potential of the NRR. Secondly, alkali molten salts were employed as the catalyst to explore and synthesize a new family of 2D layered TMNs under atmospheric pressure. The resultant 2D layered TMNs show superior performance for the HER with small overpotentials of 129 mV and 122 mV at a current density of 10 mA cm-2 in 0.5 M H2SO4 and 1 M KOH, respectively. This level of performance surpasses most of the 2D layered electrocatalysts reported in the literature. They also exhibit excellent oxidation resistance and film-forming properties for practical applications. At last, the challenges and perspectives of 2D nanomaterials for electrocatalysis were discussed. The novel 2D nanomaterials demonstrate great potential for energy-relevant electrocatalytic processes such as HER and NRR. By rationally modifying the surface property and electronic structure at atomic level, the 2D nanomaterials can be extended to more research areas. Moreover, insightfully unveiling the reaction mechanisms of electrocatalysis can lay a solid foundation for designing more efficient 2D electrocatalysts.

Johnston, Sweyn, John McGlynn, Veronica R. Prado, and Joseph Williams. Ocean Energy in the Caribbean: Technology Review, Potential Resource and Project Locational Guidance. Inter-American Development Bank, November 2021. http://dx.doi.org/10.18235/0003783.

Full text
Abstract:
This publication assesses the potential for deployment of the leading Marine Renewable Energy (MRE) technologies including Fixed Offshore Wind, Floating Offshore Wind, Ocean Thermal Energy Conversion across nine Countries of Interest (COI) in the Caribbean region. This is achieved by conducting a technology review, analysing resource levels in each of the COIs, and presenting the outputs of Locational Guidance work identifying preferred areas for potential future project development. This work concludes that MRE can offer a secure supply of indigenous clean energy, that resources are sufficiently abundant to meet the current and future energy demand of each of the COIs many times over, and that the leading MRE technologies are sufficiently advanced to be worthy of immediate prioritisation. This Technical Note draws on and presents outcomes from work undertaken in 2019 as part of a Technical Cooperation Agreement between the IDB and CDB under the Support for Sustainable and Resilient Projects in the Caribbean programme.

Kolodziejczyk, Bart. Unsettled Issues Concerning the Use of Green Ammonia Fuel in Ground Vehicles. SAE International, February 2021. http://dx.doi.org/10.4271/epr2021003.

Full text
Abstract:
While hydrogen is emerging as a clean alternative automotive fuel and energy storage medium, there are still numerous challenges to implementation, such as the economy of hydrogen production and deployment, expensive storage materials, energy intensive compression or liquefaction processes, and limited trial applications. Synthetic ammonia production, on the other hand, has been available on an industrial scale for nearly a century. Ammonia is one of the most-traded commodities globally and the second most-produced synthetic chemical after sulfuric acid. As an energy carrier, it enables effective hydrogen storage in chemical form by binding hydrogen atoms to atmospheric nitrogen. While ammonia as a fuel is still in its infancy, its unique properties render it as a potentially viable candidate for decarbonizing the automotive industry. Yet, lack of regulation and standards for automotive applications, technology readiness, and reliance on natural gas for both hydrogen feedstocks to generate the ammonia and facilitate hydrogen and nitrogen conversion into liquid ammonia add extra uncertainty to use scenarios. Unsettled Issues Concerning the Use of Green Ammonia Fuel in Ground Vehicles brings together collected knowledge on current and future prospects for the application of ammonia in ground vehicles, including the technological and regulatory challenges for this new type of clean fuel.
