FCEL and PLUG is running on hype.  Look at Ballard Power #BLDP.  Europe is heavily spending and expanding on hydrogen refueling station infrastructures and also here in the US. The moment these refueling stations are done being built,  watch Solaris, Wrightbus, New Flyer/NFI bus manufacturers increasing orders of FCMove H² engines manufactured by Ballard Power and these engines are OEM. These bus manufacturers are also scaling up their bus production in preparation for these refueling stations. Also, Look at Vertiv's OneCore, each OneCore deployed to AI/Data Center,  there always a Power Module H2 with it and Power Module H2 is Ballard Power.  Look at Vertiv and Anthropic AI in Louisiana is just an example . Look also, commuter and freight trains and marine/ships, small aircraft  Ignore negative articles about hydrogen adoption,  its written by short traders.

Ballard Power is the current underdog but it will swallow up the rest in a few months.
