Solar Fuels: A grand challenge of 21st century chemistry

The video discusses Caltech's Solar Army, led by Harry Gray, which aims to develop renewable fuels through artificial photosynthesis. The team is researching metal oxide catalysts to split water into hydrogen fuel using sunlight. Current catalysts are expensive and scarce, so the focus is on finding earth-abundant alternatives. The project involves students globally and aims to impact energy sustainability worldwide.
