Increasing the Activity of Catalysts

A key to producing green hydrogen more efficiently

13-Jan-2021

A layer as thin as a single atom makes a huge difference: On the surface of an electrode, it doubles the amount of water split in an electrolysis system without increasing the energy requirements. Thus, the ultrathin layer also doubles the amount of hydrogen produced without increasing costs. ...

Green hydrogen: buoyancy-driven convection in the electrolyte

For the first time investigated, how the liquid electrolyte throughout the cell behaves during electrolysis

23-Nov-2020

Hydrogen produced by using solar energy could contribute to a climate neutral energy system of the future. But there are hurdles on the way from laboratory scale to large-scale implementation. A team at HZB has now presented a method to visualise convection in the electrolyte and to reliably ...
