Not sure how many might have caught Sankar's comment in either the CC or the AGM. 

One of the orders is actually replacing a hydrogen fuel cell installation. This may be important as I recall an analyst suggesting PLUG Power's days are numbered because as he said, their business model is outdated.

Can fuel cells keep up with high demand or do they still need a battery or capacitor charge for the moments demand soars ?

Either way, HD on board is another hugh credit. Thanks again for your great "digging"  skills hogey.
