There has been quite an interest in energy storage recently. And as ever more power-to-gas systems have been popping up all over Germany, project planners are increasingly turning their attention to the key elements found on-site: electrolyzers. These electrochemical units to create hydrogen have been around for a long time. (more…)
Last November, H2-international published a first market overview of residential fuel cell systems. This time, we will take a closer look at electrolyzers. To try and map the current situation on the electrolyzer market, we contacted 18 manufacturers, primarily from the German-speaking region, but also from across Europe and North America. Ten of them have sent us details on their electrolyzers. Nine of them have made it onto the product list; Diamond Lite and Proton OnSite provided virtually identical information. (more…)
When we compiled our list of currently available electrolyzers, we also asked manufacturers for their opinion on the market outlook of hydrogen technologies in Europe. Their assessment tended toward the positive; all ten businesses participating in the survey at least somewhat agreed that hydrogen technologies were developing at a satisfactory rate across the continent.

Splitting water into hydrogen and oxygen with the help of electrical energy is commonly known as water electrolysis. This process matches the oxyhydrogen experiments one may remember from the classroom, albeit in reverse. If the anode and cathode in an electrolyzer cell are separated by a semipermeable membrane or a diaphragm, the gases produced by the process can be directed out of the cell individually. (more…)
Graforce Hydro based in the Köpenick suburb of Berlin, Germany, is currently developing a high-frequency electrolysis solution. It would use an electric and a magnetic field to split water, explained Jens Hanke, Graforce’s founder. He has been working on the idea in the Technology Park Adlershof since 2010. By his own account, the high-voltage field directly above the water surface “creates plasma like on the sun.” The released electrons would split water into hydrogen and oxygen, he said. (more…)
