A spin-off from the Karlsruhe Institute of Technology (KIT), Photreon, gained significant attraction at the Hannover Messe event, where it highlighted its hydrogen production technology and presented a new photoreactor panel.
The project showcased a one-square-meter prototype designed to generate hydrogen using only water and sunlight.
“We avoid the detour through electrically powered electrolysis, producing chemical energy from sunlight and water,” said photreon co-founder Paul Kant.
This system operates independently of the electrical grid and does not require the electrolyzers typically used in green hydrogen production.
Now, look, I’m not going to claim this doesn’t have a whiff of a steaming pile of BS, but if this is really as good as it says, hydrogen would be back on the menu of green options.
If one were to make hydrogen producing solar farm specifically, this could have made sense if there were efficiency gains compared to pv + electrolyser. But there ain’t, and from what i understand won’t be
