Fraunhofer Centre for Applied Photonics (CAP) has developed a laser detection system to address hydrogen leak risks in nuclear waste storage. Hydrogen can be produced from nuclear waste, presenting safety hazards.

The £1.5M project, conducted over seven years and managed by FIS360 Ltd for Sellafield's Game Changers program, allows for the mapping of hydrogen concentrations across large areas. A new compact, hand-held device is under development, funded by Innovate UK and led by bp Plc, with a completion date set for 2029. This technology aims to enhance safety as reliance on hydrogen increases in the transition to a hydrogen-based economy.
