Description du projet
Une nouvelle approche pour améliorer la production d’énergie solaire thermique
Financé par le programme Actions Marie Skłodowska-Curie, le projet ONESTEP vise à améliorer la production d’énergie photothermique dans les pays d’Europe du Nord qui ne bénéficient pas d’un ensoleillement constant. ONESTEP permettra de mieux comprendre l’ébullition induite par le rayonnement solaire dans les nanofluides. Il s’agit d’un facteur clé pour la production de vapeur à partir de l’énergie photothermique, car il permet d’améliorer l’efficacité de la technologie des capteurs solaires. Les chercheurs caractériseront deux nouveaux nanofluides et développeront de nouvelles techniques de mesure. En menant des tests d’ébullition et en élargissant les modèles existants, l’équipe de ONESTEP fournira de nouvelles méthodologies de recherche, dotant les chercheurs de compétences pour la recherche industrielle.
Objectif
As part of its Green Deal, the EU aims to decarbonize energy production by 55% compared to 1990 levels and must turn to renewable energy sources. While the northern European countries have some access to these sources, they do not have consistent amounts of sunlight for photothermal energy (PE) generation. Novel approaches are under development to allow these regions to benefit from solar resources. Solar radiation-induced boiling in nanofluids can be used for PE steam generation as it facilitates more efficient solar collector technology. However, knowledge of the mechanisms behind this boiling is severely lacking because the methods to measure these systems are inaccurate at scale and cannot be used for practical, opaque nanofluids, limiting the focus to macroscopic properties. Understanding these mechanisms is the key to advancing PE technologies. Therefore, this project endeavours to develop and use new methods to qualify and quantify the photothermal boiling process in nanofluids at the microscale. I will move from Canada to Europe to complete this ambitious project with three specific aims. First, I will characterize two novel candidate nanofluids: plasma-functionalized graphene and carbon nanofibers (mass-produced by the project exploitation partner). Second, I will develop new, distinct measurement techniques that separate this study from existing ones which only measure temperature and steam flow rate. One method will use bubble bursting acoustics to quantity the number and size of bubbles. The other will use a medical X-ray technique, computed tomography, to image photothermal boiling for the first time. Finally, I will perform boiling tests to determine potential mechanisms and extend the existing models. With these objectives fulfilled, new information and methodologies will be developed for future research, I will gain new skills and competencies to prepare me for a future in industrial research, and Europe will be ONESTEP closer to a greener future.
