Solar energy conversion of water into the environmentally clean fuel hydrogen offers one of the best long-term solutions for meeting future energy demands. Nature provides highly-evolved, finely-tuned molecular machinery for solar energy conversion that exquisitely manages photon capture and conversion processes to drive oxygenic water-splitting and carbon fixation. Our group has developed new energy conversion strategies that use one of Nature’s specialized energy-converters, the Photosystem I (PSI) protein, to drive hydrogen production from a synthetic molecular catalyst comprised of inexpensive, earth abundant materials. PSI and a cobaloxime catalyst self-assemble and the resultant complex rapidly produced hydrogen in aqueous solution upon exposure to visible light. This work establishes a strategy for enhancing photosynthetic effi
