Batteries are actually closed energy storage systems that store electricity electrochemically - and can release it again. In the case of a combination of fuel cell and electrolyzer, the energy conversion takes place differently: Here, energy storage takes place via hydrogen gas, in which water molecules are either generated (fuel cell) or split (electrolyzer). In principle, however, all three systems (battery, electrolyzer & fuel cell) are also compatible: In the form of a "hydrogen-producing battery".
The GELADEN-Podcast has often talked about new, very energy dense batteries for electric cars. In recent months, Chinese battery manufacturers such as CATL have been particularly prominent in this regard. The market for stationary batteries, on the other hand, is still often ignored: In addition to sustainable cell materials, one factor in particular plays a role here: the cost of inexpensive cells.
In precisely this niche, the zinc-hydrogen battery "Zn2H2" has now stood out as a possible hybrid solution for electricity storage with simultaneous hydrogen generation. The founders and developers Dr. Andreas Schamel and Dr. Robert Hahn present their innovation in the Battery Podcast as particularly efficient, scalable and especially cost-effective.
