As hydrogen is considered to be one of the main future energy carriers to replace fossil fuels, new sustainable processes for hydrogen production need to be established, which combine low environmental footprint with positive techno-economic impact. Besides electrochemical water splitting using electrolysis, a variety of complementary light driven processes were proposed and investigated in recent years, as direct solar-to-hydrogen alternatives, i.e. (photo-)electrochemical, solar thermal, photocatalytic and photobiological methods, but have mostly been demonstrated at lab-scale. On the other hand long-term operational stability, insufficient efficiency under solar irradiation as well as missing data on scale-up, system integration and cost prevent further technological commercialization of these technologies. Therefore it is of pressing importance not only to identify active and efficient photocatalytic systems, but also to demonstrate their performance on system level. Therefore fundamental understanding of the underlying photophysical processes is needed to integrate advanced materials in new device concepts.
This symposium will focus on new trends in the field of light driven solar fuel generation, emphasizing on scaled-up fabrication and solar fuel production at long-term operation. Therefore experts with expertise in materials modeling, synthesis, characterization, systems integration, as well as techno-economic assessment are invited to contribute and discuss recent trends and future directions of solar fuel technology.
