The hydrogen and fuel cell units deployed in heavy-duty applications have been mostly test systems for onboard energy supply. Even those systems are far from being finished products. The shared opinion among research and development laboratories is that the technologies could be used to power cars and trucks, but only up to a certain weight or load.

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.
