Накратко на български

Нанофлуидите (течности с тъмни наночастици) се изследват, за да се разбере как те генерират повече пара при слънчево нагряване. Това помага за подобряване на ефективността при производството на слънчева термична енергия и намаляването на вредните емисии.

Optimized Nanofluids for Efficient Solar Thermal Energy Production

Climate change is the greatest existential threat to the world. To overcome this challenge, the EU has set substantial decarbonization goals through the European Green Deal. Renewable energy production is among the main drivers of emission reduction and solar energy covers over half of today’s green energy generation. The most efficient solar technology is solar thermal energy capture: taking in radiation from the sun and using it directly as heat or to generate electricity through steam turbines. To improve the viability of solar thermal energy capture, water-based nanofluids (suspensions of dark, nanometric particles) are gaining traction because their photothermal (PT) boiling generates more steam than conventional technologies. However, upscaling is not currently feasible due to very little theoretical understanding of PT boiling and a lack of tools to improve this understanding. This project aimed to expand our knowledge of PT boiling and facilitate the development of novel nanotechnology for solar thermal applications. To that end, we (1) explored the material characteristics needed for boiling optimization, (2) endeavoured to develop innovative techniques to examine PT boiling using acoustics and x-rays, and (3) performed boiling tests to elucidate the mechanisms behind the PT boiling phenomenon.

Цел на проекта

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.
