Özet
The generation, separation, and storage of sustainable and environmentally friendly energy for use as a main energy source is a crucial element of the global economy. Hydrogen and SGP (salinity gradient power) are seen as viable alternatives to fossil fuels since they may be generated from environmentally friendly and clean sources, reducing reliance on fossil fuels. This study focuses on the use of membranes in renewable and environmentally friendly energy generation. Here, RED (Reverse Electrodialysis) and PRO (Pressurized Retarted Osmosis) use SGP, while fuel cells, microbial fuel cells, AEM electrolysis, SOE, AWE, and PEM electrolysis use hydrogen energy. In these technologies, membranes play a crucial role by serving as a selective permeable barrier, like the one used in purification processes. For these processes to achieve their maximum energy production capabilities, the development of membranes is of utmost importance. The research findings indicate that enhancing the performance of membranes employed in energy production requires several key improvements. In order to enhance the performance of RED membranes, it is imperative to augment ion selectivity while decreasing electrical resistivity and improving mechanical and chemical resistance as well as contamination resistance. In order to achieve optimal membrane permeability and selectivity and to reduce intrinsic concentration polarization and fouling of PRO membranes through the improvement of surface properties including hydrophilicity, roughness, and porosity, the morphology, thickness, and roughness of the PA layer must be meticulously controlled. In hydrogen energy-based processes, it is essential for membranes to possess many desirable characteristics, including strong ion conductivity, low gas permeability, high mechanical and chemical stability, and the ability to maintain consistent product quality throughout the process. This study provides a summary of the power production capacity, membrane types, and other characteristics found in the existing literature on these technologies. Furthermore, this study delineates the primary issues and potential strategies for addressing these fundamental challenges. The main conclusion drawn from this study is that the anticipated decreases in membrane expenses will play a significant role in advancing membrane technology. This, in turn, will not only enhance operational effectiveness but also foster more excitement for membrane research. This will help to advance these processes toward their theoretical capacity for energy generation.
