How is the world's first solar powered airport faring?

  TL;DR: It's ok, but expansion is tricky, as the initial installation (which was substantial) can only power the existing facilities. Also the dependability of the power grid is a concern as well.

  Grid stability is obviously the big concern, but I'm intrigued by the prospects of a hydrogen powered airport.

  Blue Planet Research in Hawaii has been demonstrating the ability to use solar energy to split water intro hydrogen, using the hydrogen as an energy storage device. The airport could use the hydrogen to power all the airport vehicles (baggage trollies, safety trucks, etc etc) saving money on fuel; that'd be a nice entry point.

  Later other airport equipment/generators could be transitioned to hydrogen powered and more panels added.
