$VRTON (+1,1%) Vertiv has with $BLDP (+1,18%) in my opinion an exciting data center setup in the showcase. Data centers, scalable from 200 kW to the multi-MW range. The Power Module H2 was demonstrated in Ohio with two Ballard 200 kW modules and is positioned as a zero-emission alternative to diesel generators.
In my opinion, the story is not yet in the course - but the technical validation is there.
