Plug builds fuel cell stacks to power electric motors (they dont build the motor). they are system integrators at the moment as they dont build the actual cell (Ballard ) but do everything else to make it possible.
There are emissions - water - just like all hydrogen fuel cell.
which stock are you talking about - you can name stocks if they are competitors or even type their whole name without getting bounced for TOS violations.
PLUG is exceptionally focused on well defined niche markets and is just starting to roll over the adjacent pins to the bowling pin they have already captured 90% market share of. (read Geoffery Moores excellent books on technology product marketing)
Many companies can thrive selling fuel cells and related technology but no one is taking PLUG out of their current market. Good luck with your vii$ and I would live to investigate them as if they have as good a product marketing strategy as PLUGs they will be worth investing in.
