Info

  • Hydrogen Station Compression and Costs from NREL - [1]. Concludes cost of compression, storage, and
  • Diaphragm compressor - for hydrogen - [2]
  • Piston compressors provide high volume. Easier to do than diaphragm compressors. No need for ultra purity in hydrogen engines. [3]

Low Pressure Storage

  • Low pressure hydrogen storage - [4] - NJ demo house.

Companies

  • Pure Energy Centre - [5]

Hydrogen Cylinders

  • 2000 PSI - 194 cu f (5.5 cu m) [6]

Hydrogen Generator

  • 200 cc/min at 3-8 bar - $9k - [7]. With 1440 minutes/day - or 0.3 cu meter per day.
  • 1000 cc/min - $3280 - for 1000 ml/min - 1.4 cu meter/day. Alkaline, 4 bar. That is 130 grams of hydrogen per day. [8]
    • Redo the same - and 10x lower cost.
    • Need 3 hours of Honda EU1000 generator - or 2.7 kWhr.

Demonstration Hydrogen Houses

  • Hopewell Project - NJ - [9]. AKA Hydrogen House - [10]
  • Scientific American - Oh, only $500k for the off-grid home - [11]

Hydrogen Engines

Fuel Cells

  • 1kW costs $5k - [13]
  • 400W for 8k Euro [14]

Efficiency

  • Efficiency from electrolysis back to electricity in fuel cells is 45% with fuel cells - p. 11 - [15]

Seminal Work by Lovins

  • 20 hydrogen myths - [16]

Resources

  • Office of Energy Efficiency and Renewable Energy - [17]
