Objectifs :
Ce travail de fin d’études a pour but de développer et d’implémenter une méthodologie d’analyse technico-économique des centrales d’énergie afin d’élargir le panel d’outils de modélisation disponible au sein d’EDF.  Cette méthodologie est ensuite validée sur des cas concrets.
Les modules économiques développés visent à terme l’implémentation des structures de coûts classiques des moyens de production d’énergie (Turbines, TAC, compresseur, etc.) ainsi que les indicateurs économiques permettant de réaliser l’analyse de cycle de vie d’un actif énergétique.

Résultats :
La première étape consiste, par une étude bibliographique, à relever les corrélations relatives aux différents moyens de production ainsi qu’aux indicateurs économiques.
Ces corrélations sont triées puis comparées avant d’être implémentées dans les modules manquants à la bibliothèque EcoSysPro.
Une méthodologie précise d’analyse économique est alors définie et appliquée à plusieurs cas d’étude. 
Une analyse technique et une modélisation précise de ces cas concrets sont menées afin d’en observer le bon comportement et d’en extraire les grandeurs utiles. 
En rassemblant ces deux axes de recherche, technique et économique, il est alors possible de valider cette méthode et de déterminer un optimum technico-économique de l’installation de production d’énergie considérée.

This Special Issue is entitled “Environmental Sustainability in Maritime Infrastructures”. Oceans and coastal areas are essential in our lives from several different points of view: social, economic, and health. Given the importance of these areas for human life, not only for the present but also for the future, it is necessary to plan future infrastructures, and maintain and adapt to the changes the existing ones. All of this taking into account the sustainability of our planet. A very significant percentage of the world's population lives permanently or enjoys their vacation periods in coastal zones, which makes them very sensitive areas, with a very high economic value and as a focus of adverse effects on public health and ecosystems. Therefore, it is considered very relevant and of great interest to launch this Special Issue to cover any aspects related to the vulnerability of coastal systems and their inhabitants (water pollution, coastal flooding, climate change, overpopulation, urban planning, waste water, plastics at sea, effects on ecosystems, etc.), as well as the use of ocean resources (fisheries, energy, tourism areas, etc.).

This Special Issue is a compilation of the recent advances in thermal fluid engineering related to supercritical CO2 power cycle development. The supercritical CO2 power cycle is considered to be one of the most promising power cycles for distributed power generation, waste heat recovery, and a topping cycle of coal, nuclear, and solar thermal heat sources. While the cycle benefits from dramatic changes in CO2 thermodynamic properties near the critical point, design, and analysis of the power cycle and its major components also face certain challenges due to the strong real gas effect and extreme operating conditions. This Special Issue will present a series of recent research results in heat transfer and fluid flow analyses and experimentation so that the accumulated knowledge can accelerate the development of this exciting future power cycle technology.

This Special Issue (SI) deals with different end-users’ perspectives on newly developed energy policy and technology. Although the importance of end-users’ preferences is not totally new to the energy sector, this issue needs to be urgently and consistently addressed if new policies, projects, and technologies are to be introduced successfully. The eight papers included in this SI are focused on various issues such as modeling the future energy demand, household energy consumption behavior, public perceptions of new energy technologies and projects, and ICT–energy efficiency interrelationship. Some papers also analyze end-users’ experiences with recently introduced energy technologies. Based on these eight articles with various topics, this SI will provide fruitful insights in assessing and forecasting the evolution of the future energy sector. I hope this SI can contribute to the increase in communication and cooperation among academic researchers as well as practitioners in energy fields.
