Different horses for different courses.
Hydrogen is a solution... An expensive, limited solution. And not the best solution for every application.
I am a big supporter of hydrogen, but I don't support "solutions" which divert monies away from real, practical solutions. Plug falls into this second category, having squandered Billions on misguided schemes. This is the primary reason why I don't like Plug as a company or as an investment.
Hydrogen is great where it is great and I invest there. For PLUG, their niche is material handling, NOT Data Centers, or stationary power.
