US manufacturer Nikola is the company currently making the most waves in the nascent hydrogen market, emerging as another success story similar to Tesla‘s. Its critics, however, consider the Phoenix-based would-be truck maker to be just as overrated as its competitor from Fremont, as it has yet to deliver on most of its promises.
The topic of hydrogen and fuel cells is also becoming increasingly hotly debated on the stock exchange. The takeover of Hydrogenics, the Canadian frontrunner in fuel cell systems for trucks and rail vehicles as well as for electrolysers, by the US company Cummins Engine, should make people sit up and even trigger a wave of further takeovers or participations of listed companies in the industry.
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.
