Solar power panels are already commonplace, but soon we will be having hydrogen panels on the rooftops as well. The Belgian Professor Johan Martens (Surface Chemistry and Catalysis) is convinced of this, reports Knack magazine. Three years ago, he presented a panel that takes water vapour from the air at night and turns it into hydrogen during the day with sunlight. The development is almost market-ready.

“In Europe there is enough sun everywhere to make our hydrogen panel work,” says Martens in Knack. In this way, the panel can contribute to energy independence: it is small-scale, modular and ideal for decentralised production. ” What is really unique is that each panel can function autonomously because all functions are built in. Water vapour and sun, that’s all you need. You could describe the process as artificial photosynthesis.”

Martens and postdocs Tom Bosserez and Jan Rongé are now working on industrial production of the panels, which will be produced on a large scale from 2026 by Solhyd, a spin-off from the University of Leuven. The invention was nominated for last week’s finals of the prestigious European Inventor Award 2022 by the European Patent Office (EPO).
