Solar Fuels: Challenges and Prospects

This lecture features a panel discussion with invited speakers discussing the challenges and prospects of solar fuels, focusing on solar hydrogen production systems, electrolyte distribution in prototypes, power requirements, material costs, and the practical implementation of technologies. The panelists address the high cost of hydrogen production, the need for smart engineering solutions to reduce costs, the importance of stability in long-term operation, and the potential markets for solar fuels. They also explore the advantages of photoelectrochemistry over traditional PV plus electrolysis systems, the potential for CO2 and nitrogen reduction, and the importance of benchmarking and standardization for large-scale systems.
