Material science in green hydrogen production: a GS3 Science & Technology and Energy Transition case study.

Why in news

Researchers at Oregon State University developed BVR-19, a metal-organic framework photocatalyst that uses sulfur bonds to produce green hydrogen from water without expensive metal catalysts.

Background

BVR-19 is a metal-organic framework that forms spontaneously in aqueous solutions at room temperature. The study highlights that while methane-steam reforming costs $1.50 per kilogram, green hydrogen currently costs around $5 per kilogram.
