On a similar note to my earlier post another resrach group in South Korea has made a major advance in producing Hydrogen from Hematite (iron ore) water and oxygen.

Unlocking the potential of rust: High-efficiency green hydrogen production from hematite

A research team affiliated with UNIST has made a discovery in developing a novel technology that produces high-efficiency hydrogen using hematite (α-Fe2O3), a form of iron oxide (Fe2O3), which has been exposed to oxygen and water.
This innovation has led to a 3.2-fold increase in efficiency compared to previous methods for producing hydrogen from water using sunlight. This breakthrough is expected to enable the use of more affordable and environmentally friendly energy in daily life.

Led by Ji-Hyun Jang in the School of Energy and Chemical Engineering at UNIST, the team has developed an eco-friendly hydrogen production system using hematite-based photoelectrodes with excellent electrical properties. The research is published in the journal ACS Energy Letters.
