Hydrogen Filling Station

Basics

• Generates Hydrogen and Dispenses it For Use in Devices Such as Fuel Cells, and Burners
• Is usually done by one of two methods:
  • Water Electrolysis
  • Hydrocarbon Reforming
• Can be dispensed in a compressed gas, or as a cryogenic liquid (Metal Hydride Storage Canisters Could Also be an Option, but are less preferable due to lifespan issues)

Off The Shelf Options

• $120k for this filling station
  • Millenium Reign Energy - $130k for 12 kg/day system. This makes $13,000 worth of fuel per year. No storage or dispensation.
  • With storage and dispensing at 6ksi; 2 kg/day production - only $120k [1]. 12 kg/day production - $325k - [2]
• This is a good project for the kids.
  • They have an education kit at 1 cu ft/hr for $4k [3]. This produces 1 kg in 350 hours - every 2 weeks. Good start.

  • They also sell the generators by themselves
