The company reported that it shipped 687 GenDrive fuel cell units during Q2 to customers that included Walmart, Procter & Gamble, and Central Grocers. This compares to 246 units shipped in the prior year period.
In its earnings press release, Plug Power said:
"The Company has secured GenDrive and GenKey deals with Volkswagen, BMW, Mercedes-Benz and Honda. The Company expects that success within the auto-manufacturing market will open up a plethora of global opportunities as these customers standardize on hydrogen fuel cells to power the electric lift trucks at their manufacturing sites worldwide."
Earlier this year, Plug Power - and the broader fuel cell space - was a huge market story, as shares in the sector exploded higher in March before tumbling through the spring.
Year-to-date, however, Plug Power is still on a tear, up more than 275%.
Other fuel cell stocks include Fuel Cell, up 2.5% in pre-market trade, and Ballad Power, also up 2.5% in the pre-market.
