Texto completoDi, Menno Di Bucchianico Daniele. "Development of processes for the valorization of lignocellulosic biomass based on renewable energies". Electronic Thesis or Diss., Normandie, 2023. http://www.theses.fr/2023NORMIR27.
Texto completoThe world is facing the impacts of climate change due to its long dependence on fossil fuels, and specifically Europe, which is facing an energy crisis, has recognized the fragility of its fossil fuel-dependent energy system and has moved strongly towards renewable energy resources. Among renewables, biomass not only powers bio-energy production but also serves as a vital source of bio-carbon, used to create high-value molecules, replacing fossil-based products. Alkyl levulinates, derived from biomass, particularly stand out for their potential as bio-additives and bio-fuels. Acid solvolysis of hexose sugars from biomass appears to be a promising and cost-effective production route, which requires further investigation not yet found in the literature. The potential of alkyl levulinate extends to its conversion into γ-valerolactone (GVL), a promising bio-solvent, commonly obtained by hydrogenation through molecular-hydrogen. Besides being a key reagent, hydrogen is also a promising energy carrier, facilitating the integration of renewable energy sources into the market. Hydrogen energy storage systems support this integration, promoting 'green' industrial transformation. This thesis focuses on technological investigation and sustainability assessment of a potential biorefinery system, integrating lignocellulosic biomass valorization, energy production, and hydrogen generation. The study encompasses experimental investigations, optimizing technologies for the production of butyl levulinate and its subsequent hydrogenation to GVL. Sustainability considerations are fundamental to the process configuration, aligning with the global shift towards renewable and carbon bio-resources. In order to answer the question of sustainability, the research presents a first section focused on the experimental investigation of the optimal technology for the production of butyl levulinate. The solvolysis of the biomass-derived hexose Fructose to butyl levulinate was investigated, in terms of optimal process conditions and kinetic modelling. Selected an effective heterogeneous catalyst, the effect of the solvent was investigated, showing the benefits of using GVL as co-solvent, together with butanol, on the conversion and dissolution kinetics of fructose. In these conditions, the solvolysis to butyl levulinate was studied in depth from a kinetic point of view, first by proposing a model for the solvolysis of 5-HMF, an intermediate in the fructose pathway, and then extending the modelling from fructose itself. A robust kinetic model, describing the reaction mechanism of solvolysis, was defined and validated, particularly under conditions of high initial fructose concentration (applying the concept of High-gravity), and including in the modelling the kinetics of dissolution, and degradation of fructose, under acidic conditions.In the second part of the research, the technological perspective was extended to the hydrogenation of butyl levulinate to GVL. Starting from a conceptual design phase, the overall fructose-to-GVL process scheme was defined, simulated, and optimized on the basis of the process intensification concept. In the third part, the process was then dropped into a real case study in Normandy, France, adapting the analysis to the local availability of lignocellulosic biomass and wind energy. The study defines a methodology for designing and integrating the energy-supply system, evaluating different scenarios. The sustainability assessment, based on key performance indicators spanning economic, environmental, and social dimensions, culminates in an aggregated overall sustainability index. The results highlight scenarios integrating the GVL biorefinery system with wind power and hydrogen energy storage as promising, demonstrating high economic profitability and reduced environmental impact. Finally, sensitivity analyses validate the robustness and reliability of the methodology, generally extendable also to other technological systems
Come previsto, il mondo sta affrontando gli effetti tangibili del cambiamento climatico come conseguenza di un'economia basata sui combustibili fossili per centinaia di anni. Oltre a dover affrontare e adottare misure correttive per limitare gli effetti del riscaldamento globale, l'Europa sta affrontando una grave crisi energetica, che rivela la fragilità del sistema energetico europeo, prevalentemente dipendente dalle importazioni di combustibili fossili. La geopolitica delle risorse fossili ha innescato la necessaria rimodulazione dell'economia energetica europea, che si sta spostando "forzatamente" verso le risorse energetiche rinnovabili per diventare un'economia fossile e a zero emissioni di carbonio. Nel panorama delle rinnovabili, le risorse più sfruttate sono l'energia solare, eolica e da biomassa. Oltre alla produzione di bioenergia, la biomassa è una fonte inestimabile di biocarbonio, che può essere sfruttata e valorizzata per la produzione di molecole ad alto valore aggiunto che possono essere utilizzate in vari settori industriali, per la produzione di carburanti, prodotti chimici, materiali e sostituendo i corrispondenti prodotti di origine fossile. In questo contesto, sono stati sviluppati sistemi innovativi di bioraffinazione della biomassa di seconda generazione per trasformare e decostruire la complessa struttura della biomassa in molecole piattaforma più semplici, che possono poi essere trasformate in molecole ad alto potenziale. Tra queste, gli alchil levulinati sono stati identificati per il loro notevole potenziale come bioadditivi e biocarburanti. Esteri dell'acido levulinico, questi composti possono essere ottenuti da derivati della biomassa, come i monosaccaridi dello zucchero, secondo diverse vie di reazione; tra queste, la solvolisi acida degli zuccheri esosi può essere una via di produzione promettente ed economicamente vantaggiosa, che richiede ulteriori indagini non ancora presenti in letteratura. Il potenziale degli alchil levulinati risiede anche nella possibilità di un ulteriore trasformazione mediante idrogenazione per produrre γ-valerolattone (GVL), una molecola con un mercato promettente come bio-solvente, grazie alle sue proprietà di stabilità, ecotossicità e biodegradabilità. L'uso dell'idrogeno gassoso è la via più comune per l'idrogenazione del GVL, ma, oltre a essere un reagente chimico fondamentale, l'idrogeno è anche uno dei principali protagonisti della transizione energetica. Infatti, come vettore energetico, l'idrogeno può portare alla piena penetrazione delle fonti energetiche rinnovabili nel mercato dell'energia, costituendo un complemento-tampone per lo stoccaggio delle energie rinnovabili intermittenti, attraverso la progettazione di sistemi di stoccaggio dell'energia dell'idrogeno (HydESS). L'accumulo di energia a idrogeno a lungo termine può consentire l'autosufficienza dei sistemi di energia rinnovabile, in quanto agisce da ponte tra le funzionalità dei sistemi Power-to-Hydrogen, in grado di assorbire i surplus energetici delle energie rinnovabili e di immagazzinarli, e quelle dei sistemi Hydrogen-to-Power, che restituiscono energia rinnovabile quando le fonti di energia primaria non sono disponibili. In quest'ottica, lo sviluppo di tali sistemi può portare all'integrazione completa e stabile delle fonti di energia rinnovabile in asset industriali già esistenti, così come in nuovi mercati industriali, come le bioraffinerie di biomassa lignocellulosica, promuovendo lo sviluppo di realtà industriali "verdi" in termini di trasformazione di materiali ed energia. Il mercato industriale globale si sta evolvendo verso la decarbonizzazione e la riqualificazione di diversi asset, attraverso investimenti in efficienza energetica e l'introduzione di processi green per la valorizzazione delle fonti rinnovabili, ma l'implementazione su larga scala di queste iniziative richiede un'analisi completa e approfondita della loro sostenibilità

Texto completoFollowing the environmental constraints to conventional power generation, renewable energy character grows very quickly thanks to government policies. In practice, the nature of primary sources is random, the introduction of renewable energy in an electrical network may impact the operation of the power system and the quality of the power. The use of probabilistic methods in planning the power system becomes necessary for a power system consisting of a large amount of less predictable sources. However, these probabilistic methods are currently limited to long-term planning due to their high computation time. In this thesis, a new probabilistic approach based on a coupling between the law of total probability and the first order reliability method is proposed to evaluate the reliability of the power system in short-term. It takes into account the probability of unanticipated failure of system components, the uncertainty in forecasts of renewable generation and consumption. With this method, the indicators used to quantify the reliability of the power system and the use of renewable resources can be determined. Therefore, the reliability of the power system incorporating less predictable renewable energy can be evaluated. The low computation time of the method allows it to be used to validate the short term planning, which is made one day in advance to the considered day (J)

Texto completoManaging the distribution of electrical energy from renewable sources such as solar and wind energy is a technological barrier to improve performance and stability of the whole process of transfer of energy sources. Thus, research on power lines used as communication media are very promising for the facility management of small and middle powers with many generators, not necessarily initially designed in a process reliability. In addition, this new option allows management to improve performance and stability in the overall process of energy transfer. This study is particularly directed to a distributed parallel management for photovoltaic and / or multi-generators including other technologies such as wind, for example connected to a DC network also serves as a communication such as PLC system architecture. The PLC, using the modulation technique, allows the transfer of information such as temperature, the instantaneous power, the self-test etc. ... needed to optimize the energy production. The aim of this work is the study of a CPL solution designed to work on HVDC bus connecting renewable energy production systems. Circuits developed for the CPL will be considered as interfaces between the DC-DC converter and smart HVDC bus. They will be based on a hardware part consists of a transceiver interface incorporating a modulation-demodulation on the HVDC bus and a signal processor which processes the information exchanged between the various input sensors and monitoring

Texto completoThe objective of this work aim to study the performance, reliability of semiconductor structures after their operation under extreme conditions, during and after electrical stress, thermal stress, and combined electro thermal stresses. The studied semiconductor structures are photovoltaic cells for applications in the field of renewable energies. These devices have been exposed to several types of degradation generating localized defects in the structures. The I (V) and C (V) characteristics and electrical parameters have been studied before and after each stress case. The Deep Level Transient Spectroscopy (DLTS) was used as advanced technique for tracking the defects created at the interface and in the bulk structures. The DLTS technique allows identifying and locating these defects within the devices, by determining their activation energy and their capture cross-Section

Texto completoThe modeling, management and optimization of renewable energy production systems is currently a challenge to develop the smart city concept. The goal of this thesis is to develop an intelligent and autonomous management system for the control and predictive supervision of the co-production of renewable energies based on smart networked sensors where the optimization is one problematic integration. From experimental measurements, we prove that it is possible to optimally self-manage the electricity production of renewable energy installations according to a combined or superposed approach of predictive models where experimental measurements allowed to refine them. Particularly, we show the useful of the proposed approach for the photovoltaic and wind turbine installations in an urban zone according to real physical parameter measurements (temperature, humidity, etc.). More precisely, this work proposes one predictive model based on the Weibull function of the power production of polycristallins and amorphous PV systems, and one 2,4 kW micro-wind system in a specific urban zone. The proposed method is has been reinforced by the statistical analysis of real measured data by using the Dickey-Fuller (DF), Goldfeld & Quandt (GQ), Durbin Watson (DW) tests and the Engle & Granger’s method. This work has shown the relevance and originality of the models developed for the reliable prediction of energy production from experimental measurements under real conditions and obtained from the GREEN platform. In addition to modeling aspects, this work has also show that it possible to implement technological solutions based on communicating sensors for the collect of physical parameters under real-time supervision IHM given the real time photovoltaic and micro-wind power productions

Texto completoOffshore wind power is quickly developing. Its cost-effectiveness, measured with the LCOE (Levelized cost of Energy) has not reached the one of onshore wind power yet. The cost of electrical connection impacts this cost-effectiveness. Depending on the distance to the onshore grid, many possibilities of architectures and associated technologies can be considered for this connection network (AC, DC etc.). The goal of this research is to provide a decision support framework for the assessment and the planning of architectures for electrical connecting networks.The architecture assessment relies on the calculations of the annual energy dissipated through the network, of the investment costs and of the annual energy curtailed due to the network unavailability. To compute these quantities, models and methods are proposed.It appears that to compare architectures, these must be have near optimal designs? Thus, a formulation of the electrical network design optimization is proposed. The formulation is generic in regard to the various architectures which are considered. A quick heuristic solving approach which gives near optimal solutions is proposed and implemented.The decision support framework makes it possible the design and the assessment of an architecture and is applied to two very different architectures. Finally, a probabilistic analytical method is proposed to take into account the models uncertainties and to study their propagation to the decision criteria

Texto completoThis thesis focuses on the study of the direct solar resource received in Reunion and numerical modeling of a solar power plant consists of: 1 / a field of linear Fresnel collectors in which circulates synthetic oil; 2 / two sensible heat storage tanks; 3 / an organic Rankine cycle. The main goal is to evaluate the performance of such power plant in the island area identified as suitable.To meet this goal, several studies have been conducted: (i) a beam solar radiation map of Reunion was made from satellite images of MeteoSat 7. This map was used to assess the availability of this resource; (ii) a new global-to-diffuse irradiance decomposition model was made from based-ground measurements at Saint-Pierre. This model is based on the representation of higher probabilities of occurrence of the diffuse fraction; (iii) the geometry of the solar collector and beam solar irradiance were modeled from an existing ray-tracing code. This code has been used, firstly, to dimension the collector using an optimization method. And secondly, to develop a fast method in order to simulate absorbed flux distribution on the linear receiver elements; (iv) unsteady-state heat transfers within the solar collector was modeled with a nodal approach; (v) annual electricity production of the power plant running in the south of the island was simulated with a monitoring and control strategy relevant for the demand of the local electricity grid.The models that have been developed during this thesis are design support tools and allow the study of control strategies control of solar power plants with linear Fresnel collector
Renaudineau, Hugues. "Hybrid Renewable Energy Sourced System : Energy Management & Self-Diagnosis". Thesis, Université de Lorraine, 2013. http://www.theses.fr/2013LORR0336/document.
Texto completoThis thesis interested on developing a stand-alone photovoltaic system with self-diagnosis possibility. A specific structure has been proposed consisting in a DC hybridization of photovoltaic sources, a Lithium-based battery and supercapacitors. Dynamics models of the boost converter and the current-fed dual-bridge DC-DC converter are proposed and an efficient state observer is proposed to estimate the models equivalent losses' parameters online. It is shown that the estimated parameters can be used in the energy management scheme, with in particular optimisation of the efficiency of paralleled structures. The photovoltaic source optimization is also studied with special attention on shading phenomenon and design of MPPT technique especially on the case of distributed series architecture. Through a specific hybridization structure, State-Of-Health estimation is tested on Li-ion and LiFePO4 batteries. It is shown that the isolated coupled-inductors Cuk converter is very efficient for battery estimation through current injection. Finally, a global energy management scheme is proposed, and the developed stand-alone photovoltaic system is validated to operate as supposed
