It's true! Why, just look how bad hurricanes have gotten.
If fuel cells were the way to safeguard from power outages from sever weather or other more local incidents, why do places like FL install traditional motor-driven gensets fueled by NG or or Diesel at each building to be backed up instead of a microgrid?
If a bad storm takes out the lines from the fuelcell to the building it does no good. In FL and CT most major supermarkets already have at least a small NG fired emergency generator to keep the lights and registers running. Here in CT some installed inlets to quickly hook up a larger diesel genset to power the refrigeration racks and HVAC. In FL most, if not all, have the inlet and many upgraded to large 500kw diesel sets to power the entire store.
